<h3>Answer;</h3>

They both involve wave interactions

<h3>Explanation;</h3>

Refraction is a property of a wave that refers to the bending of a wave as it moves from one medium to another.
Diffraction on the other hand is a property of a wave such that an object causes a wave to change direction and bend towards it.
Diffraction and refraction differ in that, refraction occurs when waves pass through an object while diffraction occurs when waves pass around an object.
The similarity between refraction and diffraction is that they both involve interactions of waves and causes waves to bend thus changing their direction.

A boy pulls with a 20 N force, at a 20 degree incline. What part of the force moves the wagon?

nalin [4]

Answer:

horizontal direction force move wagon at 18.79 N

Explanation:

given data

force F = 20 N

angle = 20 degree

to find out

What part of the force moves the wagon

solution

we know here as per attach figure

boy pull a wagon at force 20 N at angle 20 degree

so there are 2 component

x in horizontal direction i.e F cos20

and y in vertical direction i.e F sin20

so we can say

horizontal direction force is move the wagon that is

horizontal direction force = F cos 20

horizontal direction force = 20× cos20

horizontal direction force = 18.79 N

so horizontal direction force move wagon at 18.79 N

The quantity of heat Q that changes the temperature L1Tof a mass mof a substance isgiven by Q = cmt:T, where c is the specific h

White raven [17]

Answer:

a) Q = 80,000 cal

b) Q = 100,000 cal

c) Q = 540,000 cal

d) Q = 720,000 cal

Explanation:

a)1 kg from 0⁰ Ice to 0⁰ water, the heat produced is latent heat of fusion

$Q_{l} = ML_{f}$ = 1 * 80

$Q_{l}$ = 80 kCal = 80,000 cal

b) 1 kg of O°C ice water to 1 kg of 100°C boiling water

Specific heat capacity, c = 1000cal/kg.C

$Q_{c} = mc \delta T\\Q_{c} = 1 * 1000 * (100 - 0)\\Q_{c} =100000 cal$

c) 1 kg of 100°C boiling water to 1 kg of 100°C steam

Latent heat of vaporization is needed for this conversion

$Q_{v} = ML_{v} \\L_{v} = 540 kCal/kg\\Q_{v} =1* 540 \\Q_{v} = 540 kCal = 540000 cal$

d) 1 kg of O°C ice to 1 kg of 100°C steam.

Q = $Q_{L} + Q_{c} + Q_{v}$

Q = 80,000 + 100,000 + 540,000

Q = 720,000 cal
