Answer:

the stone enters the water and slows down

Explanation:

Solution:

- When light is refracted it speed is slowed down or increases depending on the medium it enters. This depends on the ratio of air-water refractive index ratio.

- The speed of an object in air is faster than speed of an object in water. Because the refractive index of air is less than that of water. In refraction, the light changes direction slightly because it slows down or speeds up, depending on what medium it is changing into.

- From this we could say as the rock enters the water and slows down it models as if the light has been refracted.

10.67m/s²

32N

Explanation:

Given parameters:

Mass of the body = 3kg

velocity of the mass = 4m/s

radius of circle = 0.75m

Unknown:

centripetal acceleration = ?

centripetal force = ?

Solution:

The centripetal force is the force that keeps a radial body in its circular motion. It is directed inward:

   Centripetal acceleration  = \frac{v^{2} }{r}

   v is the velocity of the body

    r is the radius of the circle

  putting in the parameters:

   Centripetal acceleration = \frac{4^{2} }{0.75}

    Centripetal acceleration = 10.67m/s²

Centripetal force = m  \frac{v^{2} }{r}

          m is the mass

 Centripetal force = mass x centripetal acceleration

                              = 3 x 10.67

                              = 32N

A negatively charged particle is moving to the right, directly above a wire having a current flowing to the right, as shown belo
qwelly [4]

Answer:

Explanation:

As the current in the ire is towards right and the charge particle is above the wire, the direction of magnetic field due to the current carrying wire is perpendicularly outwards to the plane of paper. It is calculated by the Maxwell's right hand thumb rule. Now by using the Fleming's left hand rule, the direction of force is upwards.
