Answer:
Adiabatic.
Explanation:
Any process in which there is no heat tranference is called adiabatic. In the situation, it is explained that due to the change of volume there is no heat between the gas and the environment.
Answer:
F = 39.2 N
Explanation:
Since, the object is in uniform motion. Therefore, the frictional force on object will be:
Frictional Force = μk N = μk mg
where,
μk = coefficient of kinetic friction = 0.2
m = mass of crate = 10 kg
g = 9.8 m/s²
Therefore,
Frictional Force = (0.2)(10 kg)(9.8 m/s²)
Frictional Force = 19.6 N
The horizontal component of force must be equal to this frictional force to continue the uniform motion:
F Sin 30° = 19.6 N
F = 19.6 N/Sin 30°
<u>F = 39.2 N</u>
Answer:
0
Explanation:
Displacement is a vector from initial to final point. Because initial and final point are the same, so displacement is 0.
It 45 because it has to be this and that and ur gay
S= 343m/s
F=256Hz
WL= 343ms/256-1
WL=V/F
= 1.339844m
