Answer:
Exact answer: a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.
Answer:
14,700 J
Explanation:
PE = Mgh = (75 kg)(9.8 m/s²)(20 m) = 14,700 J
Answer:
Resulting heat generation, Q = 77.638 kcal/h
Given:
Initial heat generation of the sphere, 
Maximum temperature, 
Radius of the sphere, r = 0.1 m
Ambient air temperature, 
= 298 K
Solution:
Now, maximum heat generation, 
is given by:
(1)
where
K = Thermal conductivity of water at 
Now, using eqn (1):
max. heat generation at maintained max. temperature of 360 K is 24924
For excess heat generation, Q:
where
Now, 1 kcal/h = 1.163 W
Therefore,
