Answer:
Induced emf through a loop of wire is 3.5 V.
Explanation:
It is given that,
Initial magnetic flux, 
Final magnetic flux, 
The magnetic flux through a loop of wire decreases in a time of 0.4 s, t = 0.4 s
We need to find the average value of the induced emf. It is equivalent to the rate of change of magnetic flux i.e.



So, the value of the induced emf through a loop of wire is 3.5 V.
The answer you are looking for is 400 joules.
The purpose of this lab is to determine whether the surface of an area would affect the coefficient of Friction. My classmates and I have learned a lot in this lab and that there could have been some errors in our lab because the strength of how a person pulls it might be a slight different than the normal force. I learned from this lab that the <span>surface area would have no effect on the coefficient of friction. </span>
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.
You get the net force acting on the object.
