Given:
The mass of each sphere is
The distance between the two spheres is r = 2 m
To find the gravitational force that one sphere exerts on the other.
Explanation:
The gravitational force is caculated by the formula
Here, the universal gravitational constant is
Substituting the values, the gravitational force will be
Final Answer: The gravitational force that one sphere exerts on the other is 1.04 x10^-8 N.

The rate of bullets per minute = 6000 per minute
= 6000/6 per sec
=10 bullets per sec
as we know
F=n * m * v
=10 . 200 . 25 .10^-3
= 2N</span>

Answer and Explanation: To know how much tape he will need, we have to calculate the perimeter of each parallelogram-shaped stripe.
Perimeter is the sum of all the sides of a figure.
For a parallelogram:
P = 2*length + 2*width
So, we need to determine width and length of the stripe.
Width is 3 inches. Length is the hypotenuse of the right triangle, whose sides are 6 and 18 inches. Then, length is
h = 19 in
Perimeter of the first stripe is
P = (2*19) + (2*3)
P = 44 inches
The hazard sign has 3 stripes. So total perimeter is
44 + 44 + 44
132 inches
To outline the parallelogram-shaped stripes, Charles need a total of 132 inches of tape. Since one roll has 144 inches, he will have enough tape to finish the job.
