Answer:

Displacement

Explanation:

We are given that average velocity is different than average speed.

We have to find what involves average velocity.

Average velocity:It is defined as the displacement per unit time.

Mathematical representation,

Average velocity=\frac{displacement}{time}=\frac{ds}{dt}

Average speed:It is defined as the distance per unit time.

Average speed=\frac{distance}{time}=[tex]\frac{s}{t}

Average velocity is different from average speed because calculating average velocity involves displacement but average speed involves distance.

In order to induce electrical energy into a conductor or generator, what three factors must be present?
salantis [7]
The electricity produced by a generator works through the concepts of the following three factors; magnetic field, voltage and current. When a conductor with current flowing in it is placed in a magnetic field, it will cause the electrons to move in a direction perpendicular to the magnetic field. When working with generators, the guide for this direction is Fleming's Right Hand Rule. Since the electron move in perpendicular motion with magnetic field all the time, it would cause it to spin in a helical direction. These turns would then induce voltage and create electricity.

A women who normally weighs 400 N stands on top of a ladder so high she is one full additional earth radius above the surface of
AveGali [126]

The woman weighs 100N now.

Explanation:

Given:

F is given as 400N

one full additional earth radius formed

To Find:

Weight of the woman=?

Solution:

We know that gravitational force is inversely proportional to the square of radius.

f_g=\frac{1}{r^2}

where

f_g is the gravitational force

r^2 is the radius square

So when radius is doubled, the force becomes one fourth of the original.

Therefore \frac{1}{4} \times400 = 100N

A rope is vibrating in such a manner that three equal-length segments are found to be vibrating up and down with 321 complete cy
kolbaska11 [484]

Answer:

<u>2.48 m</u> is the length of the rope.

Explanation:

Cycle period is 321

Time is 20 second

Wave travels at speeds = 26.4 m/s

We know that,

\text { Frequency }=\frac{1}{T} \text { (For one cycle) }

Frequency required for 321 complete cycle in 20 seconds is

\text { Frequency }(f)=\frac{321}{20}

Frequency = 16.05 hz

We know that,

\text { Wavelength }=\frac{\text { wave velocity }}{\text { frequency }}

\lambda=\frac{v}{f}

λ = wavelength, the distance between "wave crests" (m)

v = wave velocity, the "speed" that waves are moving in a direction (m/s)

f = frequency, (cycles/ or Hz)

\lambda=\frac{26,4}{16.05}

λ = 1.65 m

As per given question "length of the rope has three equal length segment"

\mathrm{Length of the rope}=\frac{3}{2} \lambda

\mathrm{Length of the rope }=\frac{3}{2} \times 1.65

\mathrm{Length of the rope}=1.5 \times 1.65

Length of the rope = 2.48 m

Therefore, length of the rope is <u>2.48 m.</u>
