Answer:
C
Mass is directly proportional to the Force of Gravity. If Mass increases, then the Force of Gravity increases; however, Distance is indirectly (or inversely) proportional to the Force of Gravity. If Distance increases, then the Force of Gravity decreases.
Explanation:
The formula for the force of gravity between two objects is
where
G is the gravitational constant
m1, m2 are the masses of the two objects
d is the separation between the two objects
We notice the following:
- F is directly proportional to the masses, . This means that if one of the masses increases, then the force between them, F, increases in a proportional way
- F is inversely proportional to the square of the distance, . This means that if the distance between the two objects is increased, the force between them will decrease, and vice-versa.
So, the correct answer is
C
Mass is directly proportional to the Force of Gravity. If Mass increases, then the Force of Gravity increases; however, Distance is indirectly (or inversely) proportional to the Force of Gravity. If Distance increases, then the Force of Gravity decreases.
Explanation:
Given that,
Initial velocity, u = 11.3 m/s
Angle above the horizontal,
Time of flight :
Horizontal distance traveled is given by :
x = ut
x = 11.3 m/s × 1.32 s
x = 14.916 m
Maximum height is given by :
Hence, time of flight is 1.32 s, horizontal distance is 14.916 m and maximum height is 2.14 m.
