Explanation:
a What is meant by zero error?
b Give an example of when you would have to allow
for it.
a) It is the error present in the measuring instrument that causes it to register a value even when there is no input or output being measured.
b) An example of when you would have to allow for zero error is when using a measuring instrument like a vernier caliper or micrometer screw gauge.
a) Zero error refers to the deviation or discrepancy in the measurement instrument, where the indication or reading on the instrument is not zero when the quantity being measured is zero. In other words, it is the error present in the measuring instrument that causes it to register a value even when there is no input or output being measured.
Zero error can occur due to various reasons such as manufacturing defects, wear and tear, misalignment, or improper calibration of the instrument. It can be positive or negative, depending on whether the instrument reads higher or lower than the actual value.
b) An example of when you would have to allow for zero error is when using a measuring instrument like a vernier caliper or micrometer screw gauge. These instruments are commonly used to measure the dimensions of objects with high precision.
In a vernier caliper, for instance, zero error can occur when the jaws do not close perfectly when there is no object being measured. If the caliper shows a reading other than zero when the jaws are closed, it indicates the presence of zero error.
To obtain accurate measurements, the zero error needs to be accounted for and compensated. This can be done by adjusting the position of the zero on the scale or by subtracting the zero error value from the measured readings.

Answer:
Explanation:
Given that,
h(t) = -9.8t² / 2 + 125t + 500
for t > 0.
At t = 0, the rocket is at height h = 500m, at a velocity of Vo = 125m/s.
We want to find the maximum height reached by rocket
Using mathematics maxima and minima
let find the turning point when dh/dt = 0
dh/dt = -9.8t + 125
dh / dt = 0 = -9.8t + 125
9.8t = 125
t = 125 / 9.8
t = 12.76s
Let find the turning point to know if this time t = 12.76 is maximum or minimum point
Let find d²h / dt²
d²h / dt² = -9.8
Since, d²h/dt² < 0, then, at t = 12.76s is the maximum points.
Then, the maximum height reached is
h = -9.8t² / 2 + 125t + 500
h = -9.8(12.76)² / 2 + 125(12.76) + 500
h = -797.80 + 1595 + 500
h = 1297.2 m
The maximum height reached is 1297.2 m
From the attachment, the maximum height is 1297.2m at t = 12.76sec.

The velocity of the punk at time t = 1.5 s is equal to 2.47 m/s.
What are the components of velocity?The object will have two velocities during the projectile motion, one is horizontal velocity and the other is vertical velocity. The horizontal velocity of the object is constant throughout the projectile motion but the vertical velocity is changed in the projectile motion.
Given that the velocity vector is making an angle θ with a horizontal table, θ = 35°
The vertical component of the velocity of the puck can be determined as:\(u_x = u Sin 35^o = 3.60 \times 0.573 =2.06 m/s\)

A 16.0 g bullet is moving to the right with speed 250 m/s when it hits a target and travels an additional 22.6 cm into the target. What are the magnitude (in N) and direction of the stopping force acting on the bullet
Answer:
The magnitude will be "2212 N".
Explanation:
The given values are:
Initial speed, u = 250 m/s
Final speed, v = 0
Mass, m = 16.0 = 0.016 kg
Distance, d = 22.6 cm
On converting cm into m, we get
d = 0.226 m
As we know,
⇒ \(v^2-u^2=-2ad\)
⇒ \(a=\frac{v^2-u^2}{-2d}\)
On putting the estimated values, we get
⇒ \(=\frac{(0)^2-(250)^2}{-2\times 0.226}\)
⇒ \(=\frac{0-62500}{-0.452}\)
⇒ \(=13,8276 \ m/s^2\)
Now,
Force, \(F=ma\)
On putting values, we get
⇒ \(=0.016\times 138276\)
⇒ \(=2212 \ N\) (magnitude)
The magnitude of the stopping force on the bullet is 2,212.4 N in opposite direction to the bullet.
The given parameters;
mass of the bullet, m = 16 gspeed of the bullet, u = 250 m/sdistance traveled by the bullet and the target, d = 22.6 cm = 0.226 mThe acceleration of the bullet is calculated as follows;
v² = u² - 2ad
where;
v is the final velocity when the bullet stops = 00 = 250² - a(2 x 0.226)
0.452a = 62500
\(a = \frac{62500}{0.452} \\\\a = 138,274.34 \ m/s^2\\\\\)
The magnitude of the stopping force on the bullet is calculated as follows;
F = ma
F = 0.016 x 138,274.34
F = 2,212.4 N
Thus, the magnitude of the stopping force on the bullet is 2,212.4 N in opposite direction to the bullet.

Describe the setup of the electromagnet. Why does the wire need to be a conductive material?
An electromagnet consists of a conductive wire wrapped around a magnetic core, creating a magnetic field when an electrical current is passed through it.
An electromagnet is a type of magnet that is created by running an electrical current through a wire. The setup of an electromagnet involves a few basic components. First, there must be a wire that is conductive, meaning that it can conduct electricity. This wire is usually wrapped around a core, which is often made of iron, steel, or another magnetic material. When an electrical current is run through the wire, it creates a magnetic field around the wire. This magnetic field then magnetizes the core, creating an even stronger magnetic field. The strength of the electromagnet can be controlled by adjusting the amount of current that is run through the wire. The wire must be a conductive material because it needs to be able to carry the electrical current that creates the magnetic field. If the wire were not conductive, then the electrical current would not be able to flow through it, and the magnetic field would not be created. In summary, the setup of an electromagnet involves a conductive wire wrapped around a magnetic core, which is magnetized by the electrical current running through the wire. The wire must be conductive to carry the electrical current and create the magnetic field.For more questions on electromagnet

In his famous gold foil experiment, Ernest Rutherford discovered that the atom was mostly composed of empty space, and that a small, dense nucleus containing the majority of the atom's mass was located at its center.
What is Rutherford?
First Baron Rutherford of Nelson Ernest Rutherford, OM, FRS, HonFRSE The father of nuclear physics is, a New Zealander who lived from 30 August 1871 to 19 October 1937. He is regarded as the greatest experimenter since Michael Faraday by Encyclopaedia Britannica (1791–1867). He worked outside of his home country for a significant portion of his career, both in Canada and in the Kingdom. Early research by Rutherford led to the discovery of the radioactive element radon, the idea of radioactive half-life, and the classification and naming of alpha and beta radiation. At McGill University in Quebec, Canada, this work was completed. It served as the foundation for his 1908 Nobel Prize in Chemistry, which was given in recognition of his studies into to the disintegration of a elements.
He also found that a small percentage of alpha particles, which are positively charged particles, were deflected rather than passing straight through the gold foil. This led to the conclusion that the atom was composed of a positively charged nucleus surrounded by negatively charged electrons.

Two loudsspeakers emit identical sound waves along the x axis. THe osund at a point on the axis has maximum intensity when the speakers are 40 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 50 cm. If the distance between the speakers continuse to increase, at what separation will the sound intensity again be a maximum?
Answer: 30 cm.
Solving
The situation described is that of two sources of sound waves that are separated by some distance. The two waves interfere with each other constructively at some points and destructively at others. When they interfere constructively, the amplitude (and intensity) of the sound wave is greater than when they interfere destructively.
When the speakers are 40 cm apart, the waves that they produce are in phase at some points on the axis, leading to constructive interference and a maximum in the intensity of the sound. As the distance between the speakers is increased beyond 40 cm, the points of constructive interference move farther apart, and the intensity of the sound decreases. When the speakers are 50 cm apart, the waves that they produce are exactly out of phase at some points on the axis, leading to complete destructive interference and a minimum in the intensity of the sound.
If the separation between the speakers continues to increase, the points of constructive interference will move closer together again, and the intensity of the sound will increase. The separation between the speakers at which the intensity of the sound will again be a maximum can be found using the following equation:
d = λ/2 + nλ
where d is the separation between the speakers, λ is the wavelength of the sound wave, and n is an integer that represents the number of half-wavelengths between the speakers.
At the maximum, the separation is an even multiple of half the wavelength, so we can use the formula above with n = 1. The wavelength can be found from the distance between the speakers at the minimum, which is 50 cm, and the distance at the maximum, which is 40 cm:
λ = 2(d_max - d_min) = 20 cm
Substituting λ and n into the formula gives:
d = λ/2 + nλ = 10 cm + 20 cm = 30 cm
Therefore, the sound intensity will be a maximum again when the separation between the speakers is 30 cm.

The frequency of microwaves in a microwave oven is 2450 MHz . What is the mode number for electromagnetic standing waves in a 42.9- cm -wide microwave oven?
The mode number for the electromagnetic standing waves in a 42.9-cm-wide microwave oven with a frequency of 2450 MHz is 7.
The mode number of standing waves in a microwave oven can be found using formula:
n = 2L/λ
λ = c/f
where c is the speed of light in vacuum and f is frequency of the microwaves.
We are given frequency of microwaves as 2450 MHz. Converting this to SI units, we get:
\(f = 2.45 * 10^9 Hz\)
The speed of light in vacuum is approximately \(3.00 *10^8 m/s\).
Now we can calculate wavelength:
\(\lambda = c/f \\\lambda = (3.00 * 10^8 m/s) / (2.45 * 10^9 Hz) \\\lambda = 0.1225 m\)
We are also given the width of the microwave oven as 42.9 cm, which we convert to meters:
L = 0.429 m
Now we can calculate the mode number:
\(n = 2L/\lambda \\n = 2(0.429 m) / 0.1225 m \\n = 7\)

Most people can throw a baseball farther than a bowling ball, and most people would find it less painful to catch a flying baseball than a bowling ball flying at the same speed as the baseball. Explain these two situations in terms of
Newton’s First Law of Motion
Newton’s Second Law of Motion
Based on Newton's first and second law of motion most people would find it less painful to catch a flying baseball than a bowling ball flying at the same speed as the baseball because the mass of the baseball is smaller and will require smaller force to be stopped.
What is Newton's first law of motion?
Newton's first law of motion first law of motion states that a body at rest or uniform motion in a straight line will continue in that path unless acted upon by an external force.
Newton's first law of motion is also called law of inertia because it depends on mass of the object.
An object with a greater mass will require greater force to be stopped or get moving.
Based on Newton's first law of motion most people would find it less painful to catch a flying baseball than a bowling ball flying at the same speed as the baseball because the mass of the baseball is smaller and will require smaller force to be stopped.
Also according to Newton's second law of motion, the force applied to an object is proportional to the product of mass and acceleration of the object. Thus, a baseball with smaller mass will require smaller force to be stopped.

What are the statements about?The term "Friction charges" refers to the process of charging an object by rubbing it against another material. When two materials are rubbed together, electrons can be transferred from one material to the other, creating a static electric charge. The resulting charge on the object is referred to as "friction charges."
Therefore, in terms of Loss electrons: The term "Loss electrons" refers to a situation in which an object loses electrons and becomes positively charged. This can occur when electrons are transferred from the object to another material through a process such as friction charging or electrical discharge. When an object loses electrons, it has a surplus of positively charged particles and is said to have a positive charge.
