There's not enough information here to calculate the answer.

Somewhere nearby, it tells you something about the numbers of turns of wire on the primary and secondary windings, but you didn't pass that info on to us. No answer is possible without it.

What is the difference between transverse and longitudinal waves?
Fed [463]

To explain how transverse and longitudinal waves work, let us give two examples for each particular case.

In the case of transverse waves, the displacement of the medium is PERPENDICULAR to the direction of the wave. One way to visualize this effect is when you have a rope and between two people the rope is shaken horizontally. The shift is done from top to bottom. This phenomenon is common to see it in solids but rarely in liquids and gases. A common application usually occurs in electromagnetic radiation.

On the other hand in the longitudinal waves the displacement of the medium is PARALLEL to the direction of propagation of the wave. A clear example of this phenomenon is when a Slinky is pushed along a table where each of the rings will also move. From practice, sound waves enclose the definition of longitudinal wave displacement.

Therefore the correct answer is:

C. In transverse waves the displacement is perpendicular to the direction of propagation of the wave, while in longitudinal waves the displacement is parallel to the direction of propagation.

A car is traveling due north at 23.6 m>s.
alexira [117]

A car is traveling due north at 23.6 m>s.

Find the velocity of the car after 7.10 s if its

acceleration is

The acceleration is known to be: a(t) = 1.7 m/s2.

We must integrate over time to obtain the velocity function, and the results are:

v(t) = (1.7m/s^2)

*t + v0

If we suppose that we begin at 23.6 m/s, then the initial velocity is: v0 = 23.6 m/s, where v0 is the beginning velocity.

The velocity formula is then: v(t) = (1.7m/s2).

*t + 23.6 m/s

We now seek to determine the value of t such that v(t) = 27.8 m/s.

Consequently, v(t) = 27.8 m/s = (1.7 m/s2)

*t + 23.6 m/s = (1.7 m/s2) 27.8 m/s - 23.6 m/s

t = 2.5 seconds when *t 4.2 m/s = (1.7 m/s/2)

At such acceleration, 2.5 seconds are required.

amm1812

Answer:

X'=50.4\,m

Explanation:

Given that:

Height of jump, h=100\,m

length of elastic cord, l=30\,m

spring constant of the cord, k=40\,N.m^{-1}

mass of the body that jumps, m=80\,kg

Force on the bungee elastic cord:

F=m.g

F=80\times 9.8

Now this force F will be responsible for the elongation in the elastic cord, so:

F=k.x ............................(1)

where :

k = spring constant

x = extension in the elastic cord

using eq. (1)

80\times 9.8=40\times x

x=19.6\,m

So the cord stretches 19.6 meters more beyond its original length of 30 meters.

Hence, the remaining distance from the river surface at the bottom is:

X'=100-(30+19.6)

X'=50.4\,m
