Velocity = distance/time taken
Velocity = 5(1000)/25(60)
Velocity = 3.33 m/s
Answer : 96 candelas
Explanation : Luminous intensity is a quantity of light that is emitted by a light source with a solid angle in a particular direction.
We know the formula of luminous intensity
Luminous intensity = illuminance x distance from light source
So, the intensity of the source will be 96 candelas.

Field strength =force/unit mass
= 14.8N/ 4kg = 3.7N/kg
Air resistance, also called drag, acts upon a falling body by slowing the body down to thr point where it stops accelerating, and it falls at a constant speed, known as the terminal volocity of a falling object. Air resistance depends on the cross sectional area of the object, which is why the effect of air resistance on a large flat surfaced object is much greater than on a small, streamlined object.
