His apparent weight will be the greatest when the elevator accelerating upward.

acceleration is the rate of to the  change of the velocity of an object with respect by  time.

When a person stand in an elevator moving upwards, he feels heavier because the elevator's floor presses harder on his feet, and the scale will show a higher reading than when the elevator is at rest.

According to Newton's second law

R = mg + ma

where;

R is the reading of the scale = apparent weight of the person

mg is the normal weight of the person

ma is the upward force acting on the person

final velocity(v)= 22m/s

time(s) = 3.5 sec

impulse = force × time

force = change in momentum/time taken

f= m(v-u)/t

f = 1.5( 22 – 15 ) / 3.5

f= 1.5 ( 7 ) /3.5

f= 10.5/3.5

f = 3N

The reason why Saturn's rings appear bright is because sunlight reflects off the ring material.

Because the ice particles in Saturn's rings scatter and reflect sunlight, the rings appear dazzling. Astronomers have long known that when Earth is directly between Saturn and the sun, Saturn's rings reflect sunlight with the greatest intensity. When light reflects off flat, polished surfaces (like a mirror or a pond) in a specific direction, it might appear exceptionally bright. The rings' actual nature becomes clear upon closer inspection. A mix of factors, such as gravity and collisions between the ring particles themselves, account for the rings' appearance of uniformity. Although the planets appear to be perfectly spherical, their spin causes them all to slightly bulge around the equator. The Saturnian ring system is the largest ring system in the Solar System.

The amplitude of an oscillating system is the magnitude of change in the oscillating variable with each oscillation. Sound waves in air, for example, are oscillations in atmospheric pressure, and their amplitudes are proportional to the pressure change during one oscillation.

When a wave travels through a medium, it loses energy as it moves. As the distance between the wave and its source grows, it spreads out over a larger and larger area. As the wave spreads through the medium, it loses energy and its amplitude decreases.
