Answer:
Jim's kinetic energy is 54.67 J.
Explanation:
Given that,
Mass, m = 15 kg
Velocity, V = 2.7 m/s
We need to find the Jim's kinetic energy. We know that when the object is in motion, it has kinetic energy. This energy is given by :
E = 54.67 J
So, Jim's kinetic energy is 54.67 J. Hence, this is the required solution.
B) The beam of light will bend three times: small angle of refraction through container wall; larger angle of refraction through water; small angle passing out of a container.

A solution, an example is salt and water. brainliest?
When ALL the forces are equal, or in general when <span>forces in the opposite direction are equal
so we can have newton example:
10 newtons X -10 newtons
netforce = 0 newtons</span>
Answer:
= 53.4 m/s
Explanation:
Velocity of a sound is given by the formula;
Velocity = Frequency × 2 (Length)
Frequency = 30 Hz
Length = 89 cm, equivalent to 0.89 M
Therefore;
Velocity = 30 × 2 ×0.89
= 53.4 m/s
Thus; the velocity or the speed of sound is 53.4 m/s
