If one balloon requires more gas to inflate, then either the temperature or the volume must be different between the two balloons
The situation you described is not possible if both balloons are inflated at the same temperature and to the same volume. According to the ideal gas law, the volume of a gas is directly proportional to the amount of gas (measured in moles) present, assuming constant temperature and pressure.
If the temperature and volume are the same for both balloons, then the number of moles of gas in each balloon should also be the same. Therefore, it should take the same amount of gas to inflate both balloons.

The speed of your automobile has a huge effect on fuel consumption. Traveling at 65 miles per hour (mph) instead of 55mph can consume almost 20% more fuel. As a general rule, for every mile per hour over 55 , you lose 2% in fuel economy. For example, if your automobile gets 30 miles per gallon at 55mph, the fuel consumption is 21 miles per gallon at 70mph. If you take a 400-mile trip and your average speed is 83mph rather than the posted speed limit of 73mph, what is the extra cost of fuel if gasoline costs $3.26 per gallon? Your car gets 30 miles per gallon (mpg) at 63mph.
The extra cost of fuel for driving 83 mph instead of 73 mph is $3.7671.

if the electric field is 108 n/c at a distance of 59 cm from a point charge q, what is the value of q (in c)? (enter the magnitude.)
If the electric field is 108 n/c at a distance of 59 cm from a point charge q, the charge on the point charge is 9.98 x \(10^{-19}\) Coulombs.
We can use the equation for the electric field produced by a point charge to find the charge:
E = k * q / \(r^{2}\)
where,
E = the electric field, equal to 108 N/C
k = the Coulomb constant, equal to 8.99 x \(10^{9}\) N \(m^{2}\) / \(C^{2}\)
q = the charge
r = the distance from the point charge, equal to 59 cm = 0.59 m
Rearranging the equation to solve for q, we get:
q = E * \(r^{2}\) / k
Plugging in the values, we get:
q = 108 N/C * \((0.59 m)^{2}\) / 8.99 x \(10^{9}\) N \(m^{2}\) / \(C^{2}\) )
q = 9.98 x \(10^{-19}\) C

11.3 g/cm³ equals to 1130 kg/m³.
What is density?The mass of a substance per unit of volume is its density. Density is most frequently represented by the symbol ρ, however Latin letter D may also be used. Density is calculated mathematically by dividing mass by volume.
Given that 11.3 g/cm³.
Know that
1000 grams = 1 kg
1 grams = 1/1000 kg.

Charging an Insulator A small metal ball is given a negative charge, then brought near (i.e., within a few millimeters) to end A of the rod. What happens to end A of the rod when the ball approaches it closely this first time?
When the negatively charged metal ball is brought near end A of the rod, the phenomenon known as induction occurs, that is, end A becomes polarized, with the side closer to the ball acquiring a positive charge and the side farther away acquiring a negative charge.
When the negatively charged metal ball is brought close to end A of the rod, the negative charge on the ball repels the electrons in the rod, causing them to move away from the ball and redistribute along the rod. This redistribution of charge leads to a separation of charges within the rod.
The end of the rod closest to the ball (end A) experiences a deficiency of electrons due to their repulsion, resulting in a positive charge. This positive charge is induced by the presence of the negatively charged ball. Meanwhile, the end of the rod farthest from the ball acquires an excess of electrons and, therefore, a negative charge.
This polarization of the charges at the ends of the rod is a temporary effect that occurs when the negatively charged ball is in close proximity to end A. It does not involve the transfer of charge between the ball and the rod but rather a redistribution of existing charge within the rod.
This polarization occurs due to the repulsion of electrons by the negatively charged ball, causing a redistribution of charges within the rod.

What single color of light illuminating a ripe banana will make it appear black?.
The single color of light illuminating a ripe banana will make it appear black will be blue light.
When lit with blue light, ripe bananas appear black. Yellow is a combination of red and green, so if blue light is flashed onto a yellow banana, the fruit will absorb the blue light, leaving nothing for the banana to reflect. The banana seems black to the eyes because there is nothing for them to reflect back to them. So, when viewed with blue light, a ripe banana appears black.
A red shirt would seem black if only blue light were shined on it because no red light would be there to reflect the blue light, which would otherwise absorb it. Ripe bananas adhere to the same standard and also white objects, which seem white because they reflect all colors.

A steel plate (50 x 50 x 0.5 cm ) is to be cast using the sand casting process. If the liquid shrinkage of the steel during solidification is 3%, calculate the following - [1+2+2] a. Volume of molten metal required to avoid shrinkage b. Calculate the dimension of a cubical riser to avoid shrinkage c. Check the adequacy of the riser using Cain's method
To avoid shrinkage in a steel plate cast using sand casting, the volume of molten metal required is calculated considering the 3% liquid shrinkage. A cubical riser with a dimension of approximately 3.37 cm can be used to compensate for the shrinkage, but a comprehensive evaluation using Cain's method requires more specific information.
a. To calculate the volume of molten metal required to avoid shrinkage, we need to consider the liquid shrinkage of the steel. The liquid shrinkage is given as 3%, which means the solidified steel will have a volume that is 3% less than the molten metal volume. Therefore, we can calculate the volume of molten metal required as follows:
Initial volume = (50 cm) x (50 cm) x (0.5 cm) = 1250 cm³
Volume of molten metal required = Initial volume / (1 - shrinkage)
= 1250 cm³ / (1 - 0.03)
= 1288.66 cm³
b. To calculate the dimension of a cubical riser to avoid shrinkage, we need to determine the additional volume required to compensate for the shrinkage. Since the liquid shrinkage is 3%, the riser should have a volume equal to 3% of the volume of the steel plate. Therefore:
Volume of the riser = 0.03 x Volume of the steel plate
= 0.03 x 1250 cm³
= 37.5 cm³
To calculate the dimension of a cubical riser, we can assume all sides are equal. Let's denote the side length of the riser as "x." Then, the volume of the riser can be expressed as:
Volume of the riser = x³
Solving for x, we find:
x = ∛(Volume of the riser)
= ∛37.5 cm³
≈ 3.37 cm
Therefore, the dimension of the cubical riser should be approximately 3.37 cm.
c. Checking the adequacy of the riser using Cain's method requires additional information and calculations related to solidification time, cooling curves, and feeding range. Without these specific details, a comprehensive evaluation using Cain's method cannot be performed within the given context.
