Answer:
Part a)

Part b)

Part c)

Part d)

Explanation:
Part a)
For hanger we know that it will have tension force upwards while it has downwards its weight so we will have

so we have

Part b)
now for car that is rolling on the floor the net force is given as



Part c)
now we know that the cart and the hanger both are connected to each other
so they must have same acceleration
so we will have



Part d)
now we know that
M = 2.40 kg
m = 0.50 kg
so we will have


Answer:
Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
Answer:
magnetic flux linkage includes number of turns, N while magnetic flux has no N
Since number of turns are not significant to units, they become similar.
Infrasound sound is any sound that are below the sound a human can hear, elephants use it to communicate with other elephants.
Explanation:
It is given that,
Speed of the sports car, v = 85 mph = 37.99 m/s
The radius of curvature, r = 525 m
Let
is the normal weight and
is the apparent weight of the person. Its apparent weight is given by :

So, 



or

Hence, this is the required solution.
