Good offer but I dont know any of this sorry
D.
The gravitational of a body is possessed by the body due to the virtue of its position.
The formula for gravitational potential energy is,
P.E = mgh joules
Substituting the values
196*9.8*250= 49k
Answer: work is the pressure acting through the change in volume
Explanation:
In the same way that work is defined as force operating over a distance, work is the pressure acting through the change in volume. Pressure is comparable to force in pressure–volume work, while volume is analogous to distance in the classic definition of work.
The amount of energy needed to increase the temperature of a substance by
is given by:
where
m is the mass of the substance
is the specific heat capacity of the substance
is the increase of temperature
In our problem,
, while
and the specific heat capacity of iron is
if we plug these numbers in the equation, we find the amount of energy needed:
Explanation:
Sorry but I don't Understand question
