An object moves 2.5 m. This is an example of a Distance

Answer: Option A

<u>Explanation:</u>

Direction denotes whether positive or negative or the left and right direction of an object. Speed and velocity are used to represent the distance travelled by the object with respect to the time taken by the object to travel.

Distance and displacement denotes the position the object has travelled from its previous location. Hence Option A is correct and B, C, D are irrelevant.

20km every 1 hr is what 20km/hr means.

so 3hrs is 20km*3=60km.

State the law of conservation of momentum<br>

trapecia [35]

Answer:

Law of conservation of momentum states that. For two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied. Therefore, momentum can neither be created nor destroyed.

A satellite is in orbit 36000km above the surface of the earth. Its angular velocity is 7.27*10^-5 rad/s. What is the velocity o

bagirrra123 [75]

Answer:

v = 3.08 km/s

Explanation:

Given that,

The angular velocity of the satellite = $\omega=7.27\times 10^{-5} rad/s$

A satellite is in orbit 36000km above the surface of the earth.

The radius of the earth is 6400 km

Let v is the velocity of the satellite. It can be calculated as :

$v=r\omega\\\\v=(36000\times 10^3+6400\times 10^3)\times 7.27\times 10^{-5}\\\\v=3082.48\ m/s\\\\v=3.08\ km/s$

So, the velocity of the satellite is 3.08 km/s.

The kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s is_____

Bond [772]

When you are talking about calculating the kinetic energy of an object, the formula is as stated:

Ek =1/2mv²

Where m is mass and v is velocity. Sub all those numbers in and you'll get 25J of kinetic energy.
