What has to be different to allow refraction to occur?a. the medium
b. the light
c. the wave
d. the speed

Answers

Answer 1

Answer: a. the medium

For refraction to occur, there has to be change from one medium to another. For example rays of light would refract as the travel from air to water.

What do multimillion-dollar sponsorships of famous athletes symbolize? a)globalization b)leadership
c)commercialization
d)sportsmanship

Answers

These sponsorships are somehow related to globalisation, as they are a global phenomenon, but some of them are on a very local scale, so globalisation is not a necessary part in them.

The best answer is c) commercialisation - atheletic competitions are turned into sources of profit, and athletes compete with the thought of winning money through it and the companies hope to increase their revenue by advertising during the sports events

An object is dropped from a height H above the ground. This free-falling object requires 1.02 s to travel the last 39 m before hitting the ground. From what height H above the ground did the object fall?

Answers

Answer:

H = 95.3 m

Explanation:

Let the height from which object fall down is H

so the total time to fall is given as

$H = (1)/(2)gt^2$

now it cover 39 m in last 1.02 s of its path

$H - 39 = (1)/(2)g(t - 1.02)^2$

so now we have

$(1)/(2)gt^2 - 39 = (1)/(2)g(t - 1.02)^2$

by solving above equation

$t = 4.41 s$

Now the total height is given as

$H = (1)/(2)gt^2$

$H = (1)/(2)g(4.41)^2$

H = 95.3 m

Can somebody please explain to me how the acceleration in simple hormonic motion is proportional to the displacement..

Answers

When you graph simple harmonic motion in an acceleration versus displacement graph, the graph at any point would be linear. The graph would also pass through the origin giving proportionality of acceleration to negative displacement. Definition of proportionality neglects the negative value of the displacement so therefore acceleration is proportional to displacement. The acceleration of the motion is always directed towards equilibrium and so at maximum displacement, there would be greatest negative acceleration and vise versa.At the origin, the displacement would be zero and acceleration would also be zero

As a wave moves through a medium, particles are displaced and
