Relate temperature to the average kinetic energy in a material.
1 answer:
<u>Answer:</u>
Temperature is always directly proportional to average kinetic energy of the material.
<u>Explanation:</u>
The average kinetic energy is given by the formula
Where K = average kinetic energy . R = gas constant , NA = avogadro's number, T = temperature
From the formula we can clearly see that K is directly proportional to T i.e kinetic energy increases with increase in temperature.
As a substance when it absorbs the heat , temperature increases which makes the faster movement of the particles thus increasing the kinetic energy.The above formula is applicable to gaseous molecules.

a) -2.516 × 10⁻⁴ V
b) -1.33 × 10⁻³ V
Explanation:
The electric field inside the sphere can be expressed as:
The potential at a distance can be represented as:
V(r) - V(0) =
V(r) - V(0) = ₀
V(r) = ₀
Given that:
q = +3.83 fc = 3.83 × 10⁻¹⁵ C
r = 0.56 cm
= 0.56 × 10⁻² m
R = 1.29 cm
= 1.29 × 10⁻² m
E₀ = 8.85 × 10⁻¹² F/m
Substituting our values; we have:
= -2.15 × 10⁻⁴ V
The difference between the radial distance and center can be expressed as:
V(r) - V(0) =
V(r) - V(0) =
V(r) =
V(r) =
V(r)
V(r) = -0.00133
V(r) = - 1.33 × 10⁻³ V
