Answer:
True.
Explanation:
The given statement is true that the law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.
According to this law, the forces between two masses can be calculated by the product of their masses and divided by the square of the distance between them. Mathematically, it can be written as :
G is universal gravitational constant
Hence, the given statement is true.
According to the statement:
a) speed is equal to 118 km/h in kilometres per hour.
b) yes it is exceeding 90km/h.
<h3>What does speed mean?</h3>The pace at which an object's position changes in any direction is referred to as speed. Speed is defined as the ratio of something like the distance traversed to the time required to cover that distance. . . Speed is a scalar quantity since it just has a direction and no magnitude..
<h3>How are the speeds determined?</h3>Speed is determined by dividing the distance by the time. Calculating the units for speed requires knowledge of the units for both time and distance.. The units in this example will be meters per second (m/s), since the distance is measured in meters (m) and the time is measured in seconds (s).
(a)s₂= 118.km/h is its speed in kilometres per hour.
1h = 3600s
1km = 1000m
s₂= (33m/s) *
= 118.8km/h
s₂= 118.km/h
(b) yes it is exceeding 90km/h.
