Answer:
The temperature raise is = 0.14 [C]
Explanation:
In order to find the temperature difference we must use the following equation:
But first we need to find the original volume V:
When the volume is increased the diameter will be larger:
D1 = 0.125[m] + 0.0002[m] = 0.1252[m]
Therefore the new radius will be:
r1=0.0626[m]
The new volume is:
Replacing all the calculated values in the equation:
Answer:
<u>Temperature is a quantity which conveys the thermal state of a body (i.e., the degree of hotness or coolness of the body). It determines the direction of the flow of heat when two bodies at different temperatures are placed in contact. The S.I. unit of temperature is Kelvin (K)</u>

Answer:
Maximum angle = 3.43⁰
Explanation:
Say that you are given the following information:
vertical distance between the charge plate = 0.03 m
length of the plate = 0.5 m
velocity of the electrons = 5 × 10⁶ ms⁻¹
the maximum angle is given by the formula:
where d = vertical distance between the charge plate
l = length of the plate
substituting the values l and d gives:
maximum angle,
= 3.43⁰
