If a truck is travelling east on a straight road and travels 100 meters in 25s what is the truck's velocity?
1 answer:
Answer:
Velocity of the truck, v = 4 m/s
Explanation:
It is given that,
Distance covered by the truck, d = 100 m
Time taken by the truck, t = 25 s
Let v is the velocity of the truck. We know that the velocity is a vector quantity. Mathematically, it is given by :
v = 4 m/s
So, the velocity of the truck is 4 m/s. Hence, this is the required solution.

The relationship between the masses of the object and the gravitational force between them is a direct relationship
Explanation:
The gravitational force between two objects is given by the equation:
where
is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between them
We observe that:
- The gravitational force is proportional to the masses of the two objects, m1 and m2, so if the masses increase, the force will increase as well (so, this is a direct relationship)
- The gravitational force is inversely proportional to the square of the separation between the objects, so if the distance is increased, the force will decrease (so, this is an inverse relationship)
