An airplane requires a much less force in order to get off the ground than a rocket does, since a rocket needs to exit Earth’s atmosphere.

Planes typically travel at much slower speeds that traditional rockets, as they are faced with varying restrictions that affect how quickly they fly.

Both forms of transportation, although very different in certain aspects, are similar in the fact that they both need to adhere to similar constraints. Although most airplanes aren’t faced with the challenge of exiting the atmosphere, they do need to focus on their fuel, their safety, etc. just as rockets do as well.

In an AC circuit with a single inductor L=1mH, what is the frequency if Irms=1.6A when Vrms=10V?
Blizzard [7]

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

Suppose a bird takes off from a tree and flies in a straight line. It reaches a speed of 1o miles per second. What is the change
lora16 [44]

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

A typical protostar may be several thousand times more luminous than the sun. what is the source of this energy?
padilas [110]

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.
