Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that the friction force on two boxes is given as
Now we know by Newton's II law
so we have
Part b)
For block B we know that net force on it will push it forward with same acceleration so we have
Part c)
If Alex push from other side then also the acceleration will be same
So for box B we can say that Net force is given as

Explanation:
hmmm,
In a gas, for example, the molecules are traveling in random directions at a variety of speeds - some are fast and some are slow. ... If more energy is put into the system, the average speed of the molecules will increase and more thermal energy or heat will be produced.

Explanation:
Answer:
158.82 rad/s
Explanation:
radius of tyre, r = 34 cm = 0.34 m
tangential speed, v = 54 m/s
Let the angular speed of the pebble is ω.
The relation between the tangential speed and the angular speed is
v = r x ω
where, r is the radius and ω be the angular speed.
54 = 0.34 x ω
ω = 158.82 rad/s
Thus, the angular speed of the pebble is 158.82 rad/s.
