Answer:

as temperature cools density increases

Explanation:

Density is the ratio of mass to volume. When the temperature varies, the volume of the liquid changes. ... Also, cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density.

What is the acceleration of an object that takes 20 sec to change from a speed of 200 m/s to 300 m/s ?

marin [14]

<u>Given</u><u>:</u>

initial velocity, u = 200 m/s

Final velocity, v = 300 m/s

Time taken, t = 20 sec

<u>To</u><u> </u><u>be</u><u> </u><u>calculated</u><u>:</u>

Calculate the acceleration of given object ?

<u>Formula</u><u> </u><u>used</u><u>:</u>

Acceleration = v - u / t

<u>Solution</u><u>:</u>

We know that,

Acceleration = v - u / t

☆ Substituting the values in the above formula,we get

Acceleration ⇒ 300 - 200 / 20

⇒ 100/20

⇒ 5 m/s²

At time t = 0 a car has a velocity of 16 m/s. It slows down with an acceleration given by

Leni [432]

Answer:

B

Explanation:

We know the inital velocity is 16 m/s

Acclereation is -0.5 m/s^2

And that final velocity is 0

We need to find time

$v _{f} = v _{i} + at$

$0 = 16 + ( - 0.5)t$

$- 16 = - 0.5t$

$32 = t$

The answer is B
