<h3># Question </h3>
Q1- the speed will increase because the particles will have more energy which causes them to move faster
Explanation:
<h3>With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature. </h3>
Answer:
Some muscles in the body are “involuntary”, which means you can't control them. The heart is made of a special involuntary muscle called cardiac muscle, and this muscle is made up of cells called cardiomyocytes (which literally means “heart muscle cells” in Latin)
Answer:
-4.72005 m/s
0 m/s
Explanation:
Displacement = 5220 km
Time = 12.8 days
The average velocity is given by

The average for the return flight is -4.72005 m/s
When the total displacement is divided by the total time of a journey then we get the average velocity.
Displacement is the minimum distance between the initial and final points of the journey.
Here, the displacement of the whole episode is 0 as the initial and final point is zero.
Hence, the average velocity for the whole episode is 0 m/s
M= gpe / gh
G= gpe / mh
H=gpe / mg
