A scooter is moving with a speed of 18 m/s. Its mass is 20 kg. What is the magnitude of its momentum?
A. 360 kg.m/s
B. 2 kg.m/s
C. 3600 kg.m/s
D. 1.1 kg.m/s
<h2><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u>:-</h2><h3>Given:-</h3>Speed (v) of a scooter = 18 m/s
Mass (m) = 20 kg
<h3>To Find:-</h3>Magnitude of its momentum (p) = ?
<h3>Answer:-</h3>Since, we know that,
p = mv
So,
p = 20 kg × 18 m/s
p = 360 kg.m/s

Answer: A- It would increase
Explanation:
According to the law of universal gravitation:
Where:
is the module of the attraction force exerted between both objects
is the universal gravitation constant.
and
are the masses of both objects
is the distance between both objects
As we can see, the gravity force is directly proportional to the mass of the bodies or objects and inversely proportional to the square of the distance that separates them.
In other words:
<h2>If we decrease the distance between both objects, the gravitational force between them will increase. </h2>
