If you and your brother both have 70 kg of mass, then . . .

-- you both weigh about 154 pounds on Earth.

-- You both weigh about 25 pounds on the Moon.

-- If you stand about 2 meters (6-1/2 feet) apart, then the force
of gravity pulling you together is about  8.2 x 10⁻⁸ newton.

That's about  0.00000029 ounce.

THAT's why.

The correct choice is 'c'.

Answer:

c)the gravitational forces of people is so small it is overshadowed by that of earth.

Explanation:

The gravitational force between two objects is given by:

F=G\frac{m_1 m_2}{r^2}

where

G is the gravitational constant

m1 and m2 are the masses of the two objects

r is the distance between the two objects

From the formula, we see that the gravitational force depends on the masses of the objects: since the mass of the Earth (5.97\cdot 10^{24} kg is much much larger than the average mass of one person (80-100 kg), then the gravitational force exerted by the Earth on a person is also much much larger than the gravitational force between two people.

How do the echoes of the sounds of animals help them?
anastassius [24]
Animals like bats and whales use something called echolocation (sounds or echoes that travel to the other animal) these echoes can let one animal let another one know that danger is near or that food is nearby etc it's like a telephone line

Describing the motion of an object
Galina-37 [17]

Answer:

In physics, motion is the change in the position of an object over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. The motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame.
