Answer:
B. Bend away from each other
Explanation:
To solve this problem we will use the concepts related to thermal expansion in a body for which the initial length, the coefficient of thermal expansion and the temperature change are related:
Where,
= Change in Length
= Coefficient of linear expansion
= Change in temperature
= Initial Length
Our values are:
Replacing we have,
Therefore the change in milimiters was 0.4126mm
Answer:
r = 9521.29
Explanation:
Given:
Gravitational Force = (Fg)
Student Mass 1 = 71 kg (M)
Student Mass 2 = 67kg (m)
Gravitational constant = (G)
r = 9521.29
Answer:
\Delta E=1.22\times 10^{-22}J
Explanation:
The energy of electron in any state is given by here h is planck's constant n is state of electron L is the infinte potential well m is the mass of electron
We know that
Potential well dimension =
Mass of electron
So energy required to electron to jump from ground state to 3rd state
Hello! I am not that good at these things but I think that the answer is A
