The current required by the 60W bulb is three-fifths that required by the 110W bulb
<h3>Electrical Power</h3>
- Electrical power is defined as the amount of electrical work done per second
- Power = electrical work done in joules/time taken in seconds
The formula for calculating power is as follows:
Assuming the voltage across the light bulbs is the same
From the formula, P = IV;
I = P/V
For the 60 W bulb
I₁ = 60/V
For the 100W bulb
I₂ = 100/V
Taking ratios of the currents:
I₁/I₂ = {60/V}/{`100/V}
I₁/I₂ = 3/5
Therefore, the current required by the 60W bulb is three-fifths that required by the 110W bulb

Suppose object A<span> is a cue ball and object </span>B<span> is an eight ball on a pool table. If the cue ball strikes the eight ball, the cue ball exerts a force on the eight ball that sends it rolling toward the pocket. At the same time, the eight ball exerts an equal and opposite force on the cue ball that brings it to a stop. Note that both the cue ball and the eight ball each experience a change in momentum. However, the sum of the momentum of the cue ball and the momentum of the eight ball remains constant throughout.</span>
The answer is c.velocity is speed and direction
Answer:
22.505 seconds
Explanation:
V =19.8m/s
V = a*to
t1 = 19.8/3.3
= 6seconds
Distance travelled during acceleration
= 1/2 x 3.3 x 6²
= 59.4m
X_total = x1 + x2
X2 = 373-59.4
X2 = 313.6m
t2 = x2/v
= 313.6/19.8
= 16.505
Total = 16.505 + 6
= 22.505 seconds
the minimum time in which an elevator can travel the 373 m from the ground floor is 22.505 seconds.
