Answer:
60V
Explanation:
240V/12 loops = 20 volts per loop.
20 * 3 = 60 volts
Answer:
200 W
Explanation:
The power is given by the ratio between the amount of work done and the time taken to perform the work:

where in this problem we have
W = 2600 J is the work done
t = 13 s is the time taken to do the work
Substituting the numbers into the equation, we find

Answer:
t = 26.39 s
Explanation:
given,
Length of runway = 1.60 mi = 8448 ft
acceleration of the jet = 10.1 ft/s²
deceleration of the jet = 7.21 ft/s²
Let x be the distance of no return
using equation of motion
v² = u² + 2 a s
v² = 0 + 2 × 10.1 × x
v = √(20.2 x)
now, after reaching that Point the deceleration of the plane start
using equation of motion
final velocity of the first case will be the initial velocity of the second case
v² = u² + 2 a s
0 = 20.2 x - 2 x 7.21 x(8448-x)
34.62 x = 121820.16
x = 3518.78 ft
time taken to reach no return point


t² = 696.788
t = 26.39 s
time taken to reach the no return point is equal to 26.39 s.
