Answer:
0.5m
Explanation:
v=f×lamda
v is 300m/s, f is 600Hz, lamda is ?
lamda=v/f
lamda=300/600
lamda =3/6=1/2m
None of the given options is correct based on the relationship for the components of the crate's weight.
The given parameter:
- <em>Angle of inclination, = q</em>
The vertical component of the force on the crate is calculated as follows;
The horizontal component of the crate is calculated as follows;
Thus, we can conclude that none of the given options is correct based on the relationship for the components of the crate's weight.

Answer:
The number of crates is 84580.
Explanation:
mass, m = 30 kg
height, h = 0.9 mm
Power, P = 0.5 hp = 0.5 x 746 W = 373 W
time, t = 1 minute = 60 s
Let the number of crates is n.
Power is given by the rate of doing work.
Answer:
Explanation:
What happens to the total amount of kinetic energy is that as the train of coaster train loses height, they tend to speed up, this makes their potential energy to convert to kinetic energy due to the height, and as the motion continues, there is continuous gaining and losing of height by the object and its speed.
Each time there is a gain in height, there is also a corresponding conversion of kinetic energy to potential energy and while for each loss of height, there is also a corresponding conversion of potential energy to kinetic energy and this is as a result of speed.
This illustrates the relationship between work and energy.
