C
- In 1665, Isaac Newton discovered that white light consists of seven colours. He found that if a beam of white light is passed through glass prism then it will split in to seven colours. These colours are red, orange, yellow, green, blue, indigo and violet (VIBGYOR).

Question 2
yarga [219]

Answer:

24.4 m

Explanation:

first we have to calculate how long the cat will be in the air, in vertical direction this is free fall from 4m (poor cat, hope he survived) with acceleration of g=9.81 m/s^2

time = sqrt ( 2 * height / g)

time = sqrt (2 * 4 / 9.81)

time = 0,903 s

then we know his horizontal flight was 22 m long, so ve can calculate verical speed

speed = length / time

speed = 22 m / 0,903 s

speed = 24.363 m

as you are asked to give 3 significant numbers answer is 24,4 m

What two motions combine to produce an orbit
NeX [460]
Field motion ( as opposed to collision motion) which are forces like gravity. And Static motion ( as opposed to kinetic motion)
Static motion is where an object moves on or around another moving object. (Circular motion)

How can the motion of a charged particle be used to distinguish between a magnetic field and an electric field in a certain regi
Helen [10]

Answer:

The charged particle follows a spiral path in a magnetic field.

Explanation:

A charge immersed in a region with an electric field experiences a force that acts along the same direction of the electric field. In particular:

- The force has the same  direction as the electric field if the charge is positive

- The force has the opposite direction as the electric field if the charge is negative

Therefore, a charge moving in an electric field is accelerated along the direction of the electric field.

On the other hand, a charge in motion in a region with a magnetic field experiences a force that acts perpendicular to the direction of the field. This means that a charge in motion in a magnetic field will acquire a circular motion in the plane perpendicular to the direction of the magnetic field.

As a result, if the particle has also a original motion outside this plane, its final motion will consist of:

- A uniform motion along that direction, +

- A circular motion along the plane perpendicular to the field

So, the resultant motion of the particle will be a spiral path. So the correct answer is

The charged particle follows a spiral path in a magnetic field.

Cold water will warm to room temperature faster in a: a) Black pot
Viktor [21]

Answer:

black pot

Explanation:

option a is correct

Cold water will warm to room temperature faster in a Black pot as we know that Black surfaces and good absorbers of heat in comparison to other surfaces. Moreover, Silver a good reflector of heat. It reflects most of heat incident on it, the cold water will take longer time to come the room temperature in Silver pot.
