<span>A) The force multiplied by the time the objects are in contact.
Hope this helps!</span>
Yhuihoifjhh <span>F = Gm1m2 / r^2
if the masses are doubled then the force is increased by a factor of 4
if the distance is doubled the force is decreased by a factor of 1/ 2^2
the net result is no change in force</span>
Answer:
v = 22.54 mph.
Explanation:
Given that,
Distance moved, d = 200 m
Time, t = 19.8 s
We need to find the runner's average speed.
We know that,
1 mile = 1609.34 m
200 m = 0.124 miles
19.8 seconds = 0.0055 h
So,
Speed = distance/time
So, the runner's average speed is 22.54 mph.
That force is what most people would call the object's "weight".
Wherever the object is, its weight is
(mass) x (acceleration due to local gravity) .
On Earth, the acceleration due to gravity is 9.8 m/s² . (rounded)
The object's weight is (20 kg) x (9.8 m/s²) = 196 newtons .
(about 44.1 pounds)
