Answer:
Kinetic energy of the brick is 26.4 Joule
Answer: Final temperature of a gold nugget will be 297 K
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

q = heat released = -4.85 kJ = -4850 J
m = mass of metal = 376 g
= final temperature of metal = ?
= initial temperature of metal = 398 K
c = specific heat of metal =



Thus the final temperature of a gold nugget will be 297 K
Let:
<span>m- 0.0600Kg </span>
<span>v1- +50.0 m/s </span>
<span>v2- -42 m/s </span>
<span>a) </span>
<span>momentum1 - momentum2 = impulse </span>
<span>p1 - p2 = Ft </span>
<span>m(v1 + v2) = Ft </span>
<span>Ft = 0.54 N-s </span>
<span>b) </span>
<span>Work is traditionally force times distance but an easy way to get through this one is to think logically and keep your units straight: </span>
<span>The racket creates an overall velocity of 90 m/s for the ball: </span>
<span>W=(Ft)*(V) </span>
<span>W=0.54 N-s * 90 m/s </span>
<span>W=48.6 N-m = 48.6 J</span>
Answer: you are the person in charge of building a nuclear power plant in Florida. your first choice is to select a site for building the power plant.
Explanation: To find the answer, we need to know more about the nuclear power plants and the criteria to select the site for power plant.
<h3>
What you mean by nuclear power plants?</h3>
- Nuclear power can be defined from the nuclear fission reaction.
- These power plants will heat the water to produce steam and this steam is used to spin large turbines and thus generates electricity.
<h3>How to select the site for nuclear power plant?</h3>
- We have to consider the following things,
- keep distance from populated area.
- distance from load center.
- Accessibility to site.
- Water availability and fuel availability.
- waste disposal.
Thus, we can conclude that, before building a nuclear power plant, our first choice should be to select a site.
