Magnetic fields and electric fields are similar on the basis of the forces and its application.

<h3>What is an electric field?</h3>

An electric field is an electric property that is connected with any location in space where a charge exists in any form. The electric force per unit charge is another term for an electric field.

Magnetic and electric fields have certain similarities, are as follows;

1. Both the electric force and magnetic forces are the non-contact forces.

2. Both acts between the two entity having certain mass.

3. Both have their respective ranges.

Hence, magnetic fields and electric fields are similar on the basis of the forces and its application.

A small marble attached to a massless thread is hung from a horizontal support. When the marble is pulled back a small distance

s2008m [1.1K]

Answer:

f' = 2 f

Explanation:

The frequency of the pendulum that swings in simple harmonic motion is given by :

$f={2\pi}\sqrt{\dfrac{l}{g}}$

Where

l is the length of pendulum

g is the acceleration due to gravity

If the length of the thread is increased by a factor of 4, such that, l' = 4 l, let f' is the new frequency such that,

$f'={2\pi}\sqrt{\dfrac{l' }{g}}$

$f'={2\pi}\sqrt{\dfrac{4l}{g}}$

$f'=2\times {2\pi}\sqrt{\dfrac{l}{g}}$

f' = 2 f

So, the new frequency of the pendulum will become 2 time of initial frequency. Hence, the correct option is (b) "2f"

How much work is done if a 50N weight is lifted to a height of 10m?

borishaifa [10]

500J

Explanation:

Given parameters:

Weight of the body = 50N

Height = 10m

Unknown:

Work done = ?

Solution;

Work done is the force that moves a body through a particular distance in the direction of the force.

In this problem, we can solve the problem by relating work done to the potential energy used in lifting the mass.

The weight on a body, a force in the presence of gravity

weight(weight) = mg

where m = mass of body

g = acceleration due to gravity

Work done = Fxd

Where F = force on the body

d = distance moved

Potential energy = mgh

where h is the height

P.E = work done = Weight x height = 50 x 10 = 500J

the particles that make up a rock are constantly in motion however a rock does not visibly vibrate. why do you think this?

Ivahew [28]

I think this is because the particles don't know or care about each other,
and they act completely without any peer pressure. The direction in which
any one particle vibrates is completely random, and there is no connection
or influence among the particles. That means that any direction is just as likely
as any other direction for the next vibration, and they all wind up vibrating in
different directions. There is a tiny tiny tiny tiny chance that all of them could
vibrate in the same direction for just an instant; if that ever happened, the rock
would suddenly jump up in the air. That's actually true, but the chance is so tiny
that it hasn't ever happened yet. In fact, the chance is so tiny, that when scientists
do their calculations of particle vibrations, they assume that the chance is zero,
and that makes the calculations simpler.
