Answer:
300J
The total work done or energy transferred is equal to the product of the force and the displacement in the direction of the force applied.
In this case it would be
300N x 10m to get 3000J.
This energy is transferred in 10 seconds and since power is energy transferred per unit time.
3000J ÷ 10 = 300 Watts or 300 Joules per second.
so your answer is 300 W
Answer:
The two waves will add vectorially to produce a small amplitude wave in a valley phase.
Explanation:
The two waves will add vectorially to produce a small amplitude wave in a valley phase. This is because the amplitudes of the waves are slightly different and in opposite directions. When wave 1 cancels out all of wave 2, the resultant wave would be the slight difference between both waves, and it would be in the direction of wave 1 which is a valley phase.
Answer:
intensity is 8.9 x W/m²
power is 11.3 x W
Explanation:
Given data
distance = 20 light year
power output = 4.00 x 10^28
to find out
intensity of the starlight and the power of the starlight
solution
we know the intensity formula that is
intensity = power / area
so here power is 4.00 x 10^28 and area = 4π(20ly)²
intensity = 4.00 x 10^28 / (4π (20×9.46×10^15)²
intensity = 8.9 x
so intensity is 8.9 x W/m²
and
power is Intensity × Area
so power = 8.9 x × (π (6.37 × 10^6)²
power = 11.3 x
so power is 11.3 x W
