Answer the following question

Ray Of Light [21]

Answer:

A) OA, AB, BC

B) 25m/s^2

C) see explanation

D) 25

E) Rest

Explanation:

From the Velocity time graph shown:

The positive slope = OA ; This is positive because, it is the point of uniform acceleration on the graph.

Constant slope = AB, the slope here is constant because, AB on the graph is the point of constant velocity.

-ve slope = BC

B) Acceleration of body in path OA.

Acceleration = change in Velocity / time

Acceleration = (150 - 0) / 6

Acceleration = 150/6 = 25m/s^2

C) Path AB is Parallel to the because it marks the period of constant velocity (that is Velocity does not increase or decrease during the time interval).

D) Length of BC

BC corresponds to the distance moved, that velocity / time

Velocity = 150 ; time = 6

Therefore Distance (BC) = 150/6 = 25

E.) Velocity =0 ; Hence body is at rest

Use the passage to answer the question.

Studentka2010 [4]

This is not something that waves do because they need a medium to travel through, while particles do not.

<h3>How light travels in space?</h3>

A light travels without any medium while on the other hand, a medium is required for sound waves to move from oe place to another. Sound is a mechanical wave that cannot travel through a vacuum.

So we can conclude that electromagnetic waves like light do not require medium for its propagation.

A boy whirls a stone in a horizontal circle of radius 1.50m and at height 2.00m above level ground. The string breaks, and the s

Eddi Din [679]

Answer:

$a_{cp}=162.2m/s^2$

Explanation:

The time the stone takes to fall can be calculated considering only the vertical component with the formula:

$y=y_0+v_{0y}t+\frac{a_yt^2}{2}$

Taking the inital height as 0m and downward direction positive, since it departs from (vertical) rest we have:

$y=\frac{gt^2}{2}$

Which gives us a time:

$t=\sqrt{\frac{2y}{g}}=\sqrt{\frac{2(2m)}{(9.8m/s^2)}}=0.64s$

Horizontally, on that time the stone travelled a distance x=10m, which means its horizontal speed was:

$v_x=\frac{x}{t}=\frac{10m}{0.64s}=15.6m/s$

Since <u>this speed is the tangential velocity</u> while whirling, the centripetal acceleration of the stone was:

$a_{cp}=\frac{v_x^2}{r}=\frac{(15.6m/s)^2}{(1.5m)}=162.2m/s^2$

Compare and contrast vertical and lateral acceleration

Drupady [299]

The answer to the question asked above is vertical acceleration is the acceleration of a body in a vertical path either up or down, while lateral acceleration is the acceleration of body in a side manner either left of right.
