<u>Answer:</u> The correct answer is Option D.

<u>Explanation:</u>

Diffraction is defined as the phenomena where light starts to bend as it passes through the edge of the object.

Interference is defined as the phenomena in which two waves superimpose each other to form a resultant wave having greater, lower or same amplitude.

Reflection is defined as the phenomena where the light falling on shiny surface bounces at different angles.

Refraction is defined as the phenomena in which bending of light takes place when it travels from one medium to another medium.

Hence, from the above information, it is visible that the correct answer is Option D.

It's refraction....When light bends on passing from one medium to another is refraction !

Jan is holding an ice cube. What causes the ice to melt?
Alexxandr [17]

The ice melts because Thermal energy from Jan’s hand is transferred to the ice.

<h3>What is thermal energy?</h3>

Thermal energy is the energy due to temperature difference.

Thermal energy flows from hotter to colder bodies.

The ice Jan is holding melts because heat is transferred from his hands t the ice.

In conclusion, thermal energy flow causes melting.

The image produced by a convex mirror is always closer to the mirror than it would be in a plane mirror for the same object dist
rosijanka [135]

Answer:

True

Explanation:

The image produced a convex mirror is always virtual irrespective of location. The size of the image is always smaller than the object. In a plane mirror the distance of the object and the distance of the image is same. But in a convex the image distance is always less than the object distance.

So, this statement is true.

Jose is loading his luggage into his car so that he can go to visit his grandmother. He lifts his suitcase up a 10 m staircase i
maxonik [38]

Answer:

The work done on the suitcase is, W = 600 J

Explanation:

Given,

The average force exerted by Jose on his suitcase,  F = 60 N

Jose carried the suitcase to a distance, S = 10 m

The work done on the suitcase is given by the relation

                           <em>W = F x S</em>

Substituting the given values in the above equation,

                            W = 60 N x 10 m

                                 = 600 J

Hence, the work done on the suitcase is, W = 600 J

How to solve part (b)?​
maria [59]

Answer:

<em>1.11m</em>

Explanation:

From the diagram we are given the following forces;

F1 = 24.3N

F3 = 30N

Since the sum of upward forces is equal to that of downward force, then;

F2 = F1 + F3

F2 = 24.3N + 30N

F2 = 54.3N

Required

Distance between B and C

First we need to get Length of AC

Take moment about A

Anticlockwise moment = F3 cos20 * AC

Anticlockwise moment = 30ACcos 20

Clockwise moment = 1.2 * F2

Clockwise moment = 1.2(54.3) = 65.16Nm

Applying the principle of moment;

Sum of ACW moment = Sum of CW moments

30ACcos 20 = 65.16

AC = 65.16/30cos20

AC = 65.16/28.19

AC = 2.31m

Get the distance BC

AC = AB + BC

BC = AC-AB

BC = 2.31 - 1.2

BC = 1.11m

Hence the separation between B and C is 1.11m

<em>Note that the force F1 got in (a) was the value used in the calculation.</em>
