Answer:
3.004A
Explanation:
The voltage across an inductor is expressed as:
Given
f = 270Hz
V = 48V
L =0.053 H
Get the current
270 = I (2*3.14*270*0.053)
270 = 89.8668I
I = 270/89.8668
I = 3.004A
Hence the current in the inductor is 3.004A
Answer:
c
Explanation:
c. This can be either a converging or diverging lens, as more information is needed for a final determination.
Answer:
The sun is a star in the milky way galaxy and the sun has eight planets and large number of asteroids and comets that are revolving around them in a path. On the other hand, the moon are revolving around the planets. The composition of the star are absolutely different from the planets and there are lots of star but the sun is the closest to the earth.
Answer:
False.
Explanation:
The forces acting on the rocket would be the engine pushing it forward, but it would also be the force of gravity and air friction acting in the reverse direction of the force of the engine. And so some energy in the form of heat, vibration, etc. would be lost to these forces, and the maximum amount of work would not be converted into kinetic energy.
So it's wrong with the statement. The work done by the engine-generated power would be higher than the Kinetic energy, as some of the energy is lost to non-conservative forces (gravity, air resistance, etc.).
