Answer:
gravitational potential energy of 10 kg mass is 122.625 J
Explanation:
Gravitational Potential energy gain is given as

here we know that
m = 10 kg
h = 1.25 m
now from above formula we have


So gravitational potential energy of 10 kg mass is 122.625 J
Explanation:
The specific heat capacity is the heat or energy required to change one unit mass of a substance of a constant volume by 1 °C. The formula is Cv = Q / (ΔT ⨉ m) .
semiconductors ... silicon, germanium etc ...
Answer:
Michael's final velocity is 19.62 m/s.
Explanation:
We can find the final velocity of Michael by using the following kinematic equation:
(1)
Where:
: is the final velocity =?
: is the initial velocity = 1.62 m/s
a: is the acceleration = 1.2 m/s²
t: is the time = 15 s
By entering the above values into equation (1) we have:


Therefore, Michael's final velocity is 19.62 m/s.
I hope it helps you!
The answer is C Because it is just C
