Answer:
994.718Hz
Explanation:
[V(rms) / I(rms)] = 2ΠfL
Vrms = 10V
Irms = 1.6A
L = 1mH = 1*10⁻³H
f = ?
[V(rms) / I(rms)] = 2ΠfL
10 / 1.6 = 2π*1*10⁻³f
6.25 = 6.28*10⁻³f
f = 994.718Hz
The frequency across the inductor is 994.718Hz
Answer:
10miles/second
Explanation:
Change in velocity of the bird is expressed as the difference between the final velocity and initial velocity of the body.
Change in velocity = Final velocity - initial velocity
Since the bird takes off from the tree, the initial velocity of the bird = 0miles/sec
Final velocity = 10miles/secs
Change in velocity = 10-0
Change in velocity = 10miles/second
The source of this energy is from the release of gravitational energy as the protostar continues to shrink.
<h3>How are stars born and what is a protostar?</h3>
Nebulae have as possible differences in gas and dust. Some factors, such as turbulence, can cause one of them to contract. This contraction of the set of materials causes the elaboration and execution of this phase of materials, generating what is usually called, in this protostar.
A protostar is formed by the contraction of a giant molecular cloud in the interstellar medium. Stars form within relatively dense concentrations of interstellar gas and dust known as molecular clouds.
