Well, your muscles are made of of the two (most important) filaments. When one of them moves over the other <span>filaments, the muscles is contracted. If there is an answer choice, I may be able to provide you with a more accurate answer, if this did not already help. ;)</span>
The Correct answer: 18
They are also known as families because they are in the same column.
Answer:
Explanation:
average velocity is 41.6/1.89 = 22.0 m/s
initial velocity u is
22.0 = (u + u - 9.81(1.89))/2
44.0 = 2u - 18.5
62.56 = 2u
u = 31.3 m/s
max height is
v² = u² + 2as
s = (v² - u²) / 2a
s = (0² - 31.3²) / (2(-9.81)) = 49.9 m
49.9 = 41.6 = 8.27 m higher
In process numbers have been rounded to 3 s.d. for reporting purposes.
The magnitude of force acting on the body is 36N
As the temperature of the lead and helium is the same. Thus the average kinetic energy is also the same for lead and helium.
Reason:
It is given that a 5.0-kg bar of lead is placed inside a 12-L chamber filled with helium gas. The temperature of the lead and helium is the same. It is required to compare the average kinetic energy of the lead atoms and helium atoms.
The average kinetic energy is calculated as,
.
Here K is the average kinetic energy, R is the gas constant, N is the Avogadro's number, and T is the temperature.
As the temperature is the same for both lead and helium. As a result, the average kinetic energy is also the same for lead and helium.
