First law of thermodynamics
Explanation:
The statement that energy can that "energy can neither be created nor destroyed but changed or transformed from one form to another" is the first law of thermodynamics.
- Thermodynamics deals with energy changes that accompanies a process.
- we can deduce from the first law that energy is conserved in every system.
- Energy is simply not produced by converted from one form to another in nature.
- For example, the heat energy we derive from eating food is due to the chemical energy stored in them.
- The chemical energy is converted into heat energy during digestion.

Answer:
The families are thought to form as a result of collisions between asteroids. In many or most cases the parent body was shattered, but there are also several families which resulted from a large cratering event which did not disrupt the parent body (e.g. the Vesta, Pallas, Hygiea, and Massalia families).
Answer:
3500j
0.250 kg
14.14 m/s
220500 j
93.91 m/s
Explanation:
K.E =1/2 m v^2
first question
1/2×700×10=3500 j
second question
2×78.2/25^2= 0.250 kg
Third question
8kj=8000j
root (2×8000/80)= 14.14 m/s
Last one
P.E=MGH
so it will be
P.E=50×450×9.8=220500 j
the speed
root (2×220500/50)=93.91 m/s
By working with percentages, we want to see how many inches is the center of gravity out of the limits. We will find that the CG is 1.45 inches out of limits.
<h3>What are the limits?</h3>
First, we need to find the limits.
We know that the MAC is 58 inches, and the limits are from 26% to 43% MAC.
So if 58 in is the 100%, the 26% and 43% of that are:
- 26% → (26%/100%)*58in = 0.26*58 in = 15.08 in
- 43% → (43%/100%)*58in = 0.43*58 in = 24.94 in.
But we know that the CG is found to be 45.5% MAC, then it measures:
(45.5%/100%)*58in = 0.455*58in = 26.39 in
We need to compare it with the largest limit, so we get:
26.39 in - 24.94 in = 1.45 in
This means that the CG is 1.45 inches out of limits.
