Answer:
The distance traveled!
Explanation:
This is a velocity time graph of an object moving in a straight line due North.
Answer:
Acceleration is 9.8 m/s^2
Explanation:
If the boulder falls from the cliff then the gravitational force will apply on it and due to gravitational force, the acceleration will be generated. Moreover, the acceleration generated in this case will be called the acceleration due to gravity. Therefore, the acceleration will remain constant irrespective of time and height because the gravitational force is constant. Thus, acceleration is 9.8 meters per second square.
Answer:
1 m = 100 cm
6 m = 600 cm
63 cm is less than either of those.
Answer:
B) 4/5
Explanation:
The magnitude of the electric force between the two spheres is given by
where
k is the Coulombs' constant
q1 and q2 are the charges on the two spheres
r is the distance between the two spheres
Initially, we have
So the force is
Later, the two spheres are brought together so they are in contact: this means that the total charge will redistribute equally on the two spheres (because they are identical).
The total charge is
So each sphere will have a charge of
So, the new force will be
And so the ratio of the two forces is
