Answer:
1964.8 J
1150 Joules
Explanation:
m = Mass of bullet = 0.5 kg
= Change in temperature = (327-20)
c = Specific heat of lead = 128 J/kg °C
=
= Latent heat of fusion of lead =
(Values taken from properties of lead table)
Heat is given by
The heat needed to raise the bullet to its final temperature is 1964.8 J
Change in volume is given by
The volume of the bullet when it comes to rest is
Heat needed for melting
The additional heat needed to melt the bullet is 1150 Joules
Answer:
Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity.
It is falling instead of flowing, because elavation is an important part of the hydroeletric power plant, since gravity is a thing, and there was elevation, than it would be falling and not flowing.
Should be -9.8m/s^2!!! The force of gravity is the only thing pushing it down!!
