Answer & Explanation:

Scientists call them all electromagnetic radiation. The waves of energy are called electromagnetic (EM) because they have oscillating electric and magnetic fields. Scientists classify them by their frequency or wavelength, going from high to low frequency (short to long wavelength).

If a seagull drops a shell from rest at a height of 12 m how fast is the shell moving when it hits the rocks
Dvinal [7]

As seagull drops a shell from rest at a height of 12 m, so we use kinematic equation of motion,

v^{2} = u^{2} +2g h

Here, h is the height, u is initial velocity , v is final velocity and g is acceleration due to gravity.

Given,  h = 12 m.

We take, g = 9.8 \ m/s^2 and u = 0 because seagull drops a  shell from rest.

Therefore, the speed of shell when it hits the rocks,

v^{2} = 0 + 2 \times 9.8 m/s^2 \times 12 \ m = 235.2 (m/s)^2 \\\\ v = \sqrt{235.2 (m/s)^2} = 15.33 \ m/s^2

A jogger runs 300 meters due east and then turns and runs 500 meters due west.
valentina_108 [34]
It’ll be 200 meters West because 500-300=200 and The west direction has the greatest force you could say ... Anytime you have a question asking about displacement you subtract then use the direction with the greatest number ..

Summarize how the sign of the charge affects the direction of the force (attraction or repulsion) in two complete sentences or m
Oksi-84 [34.3K]
  • Unlike charges attract .
  • like charges repel .

There are two types of charges

Namely :

  • positive
  • negative

On loosing electrons , a neutral body acquires positive charge .

On gaining electrons , a neutral body acquires negative charge .

The amount of charge present in a body , either positive or negative , is expressed in terms of an integral number of charge of an electron , which is considered the elementary entity of an electric charge .
