What happens to the gravitational force between two objects if the distance between them triples?

2 answers:

5 0

So as two objects are separated from each other, the force of gravitational attraction between them also decreases. ... If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).

So the answer you are looking for is B.

The answer will be B.

Gravity obeys something called the inverse square law.

This means if distance increases by a factor of x, the force of gravity will decrease by a factor of x^2

For example, if distance increases by 2, the force would be 4 times weaker

If Distance increases by a factor of 3, the force will be 9 times weaker

Two lumps of clay approach each other from opposite directions and collide head on inelastically, combing into one large lump af

Nataly [62]

Answer:

Before collision:

momentum to right = .14 * 3.5 = .49 kg m / s

momentum to left = .62 * 4.81 = 2.98 kg m / s

Total momentum = .49 - 2.98 = - 2.49 to left

M V = -2.49 net momentum to left

V = -2.49 / (.14 + .62) = -3.28 m/s to left

anyanavicka [17]

Answer:

$a = 4.07 m/s^2$

now his maximum speed is given as

$v = 3a = 12.21 m/s$

Explanation:

Total time for which Usain Bolt accelerated is given as

$t_1 = 3 s$

now the velocity after uniform acceleration is given as

$v_1 = 0 + 3a$

now remaining time for which he run for the finish line is given as

$t_2 = (9.69 - 3) = 6.69 s$

now the distance moved by him during uniform acceleration is given as

$d_1 = \frac{1}{2}a(3^2)$

$d_1 = 4.5 a$

another distance that he moved for uniform speed is given as

$d_2 = (3a)(6.69)$

$d_2 = 20.07 a$

now total distance moved by him is 100 m so we have

$20.07 a + 4.5 a = 100$

$a = 4.07 m/s^2$

now his maximum speed is given as

$v = 3a = 12.21 m/s$

A 1.7 kg model airplane is flying north at 12.5 m/s initially, and 25 seconds later is observed heading 30 degrees west of north

maxonik [38]

Answer:

Average net force = 0.62 N

Explanation:

We are given;

Mass; m = 1.7 kg

Initial velocity; u = 12.5 m/s

Final velocity; v = 25 m/s

time; t = 25 seconds

Now, we are told that the final velocity was 30° west of North. So, resolving this velocity along the horizontal gives;

v = 25 cos 30°

Now, using Newton's first equation of motion gives;

v = u + at

Where a is acceleration

Plugging in the relevant values gives;

25 cos 30° = 12.5 + 25a

21.6506 - 12.5 = 25a

a = (21.6506 - 12.5)/25

a = 0.3660 m/s²

Now, magnitude of the average net force would be; F = ma

F = 1.7 × 0.366

F ≈ 0.62 N
