Answer:
6. Acceleration = 4.74 m/s^2
7. Centripetal force = 40.5 N
Explanation:
Problem 6.
Recall that the centripetal acceleration is defined as: , where V is the object's tangential velocity, and r the radius of the circular motion. Therefore, in or case, the centripetal acceleration would be:
which we can round to 4.74 m/s^2 (option b in your list)
Problem 7.
Now we need to find not just the centripetal acceleration using the same formula as above, but then the centripetal force.
Now we calculate the centripetal force by multiplying this acceleration times the mass of the object following the definition of force as mass times acceleration:
Centripetal force = 5.0 kg * 8.1 m/s^2 = 40.5 N

True
Explanation:
The number density of an ideal gas at stp is called the loschmidt number, being named after the Austrian physicist Johann Josef Loschmidt who first estimated this quantity in 1865
n =
where is the Boltzman constant
T is the temperature
P is the pressure
Loschmidt Number is the number of molecules of gas present in one cubic centimetre of it at STP conditions.Loschmidt constant is also used to define the amagat, which is a practical unit of number density for gases and other substances:
1 amagat = n = 2.6867811×1025 m−3,
