Answer:
The answer is C
Explanation:
The magnitude of the gravitational force depends inversely on the square of the radial distance between the centers of the two masses. Thus, essentially, the force can only fall to zero, when the denominator that is r becomes infinite.
Without being provided a list of items, I would have to generally say that everything around you is matter. There are a few exceptions to this list, but a general rule of thumb is anything you can touch, taste, smell or hold would be considered matter. Sound, light, time (Dr. Who may disagree) and heat would be considered non-matter items.
The first answer in the blank is pours out of you, the second answer in the space provided is diffuse. It is because a person who has an effusive personality will likely pour out his or her emotions while the motor oil will likely diffuse if this has been spilled out of the can.
Answer:
Explanation:
We shall consider all movement with respect to water assuming that river is at rest or motionless .
speed of canoe = 5 m /s
in five minutes , distance between hat and canoe = 5 x 60 x 5
1500 m
This distance will be covered by man in return journey . In this case his speed is 5 m /s again considering river constant .
So this will be covered at 5 m /s
time taken = 1500 / 5 = 300 s
= 5 minutes .
so it will take 5 minutes to row back to reclaim his hat .
