HELP! A 20-kg bag of rice dropped from an airplane. What is the gravitational force on the bag? Acceleration due to gravity is 9.8 m/s/s.)
10.02 N

19.6 N

20.8 N

196 N

Answers

Answer:

20.8

Explanation:

I took it and it was right

196N is the gravitational force on the bag. So, the correct option is D.

What is gravitational force?

Any two items in the universe can be attracted to one another by the gravitational force. All mass-containing objects are drawn towards one another by this attraction, which also keeps the moon in its orbit around the Earth and the planets in their orbits around the sun.

The mass of the two objects and their separation determine the gravitational force's strength. The force of gravity between two objects is directly proportional to their masses and inversely correlated to the square of their distance, according to Newton's law of universal gravitation.

The gravitational force on the bag can be calculated using the formula:

force = mass x acceleration due to gravity

Plugging in the given values, we get:

Force = 20 kg x 9.8 m/s/s

Force = 196 N

Therefore, the correct option is D.

a. a gain of protons

b. a loss of protons

c a gain of electrons

d. a loss of electrons

Explanation:

:) answer mom

The charge of object y will be positive since it will have excess proton and less electron.

What is positive charge?

A positive charge is obtained when an atom losses its electron usually a metal. It simply defines the excess of proton in an atom or deficient of electron in an atom.

If object x acquires a negative charge, then object y must have supplied the excess electron to it.

Thus, the charge of object y will be positive since it will have excess proton and less electron.
