Answer:
B
Explanation:
im sure that the last one and the first are correct and the second one is wrong .
Answer:
when volume and the number of particles are constant
Explanation:
Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Gay Lussac's law is given by;

The ideal gas law is the equation PV = nRT
Where;
P is the pressure.
V is the volume.
n is the number of moles of substance.
R is the ideal gas constant.
T is the temperature.
Generally, raising the temperature of an ideal gas would increase its pressure when volume and the number of particles are constant.
This ultimately implies that, when volume and the number of particles are held constant, there would be a linear relationship between the temperature and pressure of a gas i.e temperature would be directly proportional to the pressure of the gas. Thus, an increase in the temperature of the gas would cause an increase in the pressure of the gas at constant volume and number of particles.
It would be true. Excess radiation causes cancer.
Answer:
Explanation:
Given
mass of car 
Vertical displacement 
spring constant 
Considering we need to find out compression in the spring when it reaches to ground
Here Gravitational potential Energy is converted to kinetic energy which finally converts to Elastic Potential Energy
suppose x is the compression in spring
Potential Energy=mgh
Elastic potential energy
