Answer:

Explanation:
From the question we are told that:
Charge 
Velocity 
Angle 
Magnetic field 
Generally the equation for Force is mathematically given by


Therefore


Answer:
1. The change in temperature of the material.
2. The length of the material.
3. The type of material.
Explanation:
The term linear expansion is defined as the increase in length of any conductor when there is a change in temperature. The new length of any wire or rod is given by :

is the initial length of the rod
is the coefficient of linear expansion
is the change in temperature
It is clear that the linear expansion of a material depends on :
1. The change in temperature of the material.
2. The length of the material.
3. The type of material.
So, all options are correct.
distance of each pan from the center or fulcrum is given as

now if dishonest shopkeeper shifted it by 0.633 cm from center
so distance on each side is given as


now the weight is balance as


now we will have

now we can find the percentage change as


Arrhenius' equation relates the dependence of rate constant of a chemical reaction to the temperature. The equation below is the Arrhenius equation

where k is the rate constant, T is the absolute temperature. As the temperature of the system increases, the rate constant also increases and vice versa.
Answer:

Explanation:
From conservation of energy states that
