Two asteroids are found at the same distance from the Sun. However, one asteroid is twice as massive the other. According to New
astraxan [27]

Answer:

IS TWICE THAT OF THE GRAVITATIONAL FORCE BETWEEN THE SMALLER ASTEROID AND THE SUN

Explanation:

The equation for gravitational force is:

F = G *  \frac{m1 * m2}{r^2}

where G is the gravitational constant.

Given that distance remains constant, and the mass of the bigger asteroid is bigger, we can get the following relation:

G *  \frac{2*m1 * m2}{r^2} = G *  \frac{m1 * m2}{r^2}

Here we can see that multiplying the mass by 2 gives us 2 times the gravitational force for the bigger asteroid.

Thus, the gravitational force for the bigger asteroid and the sun is two times that of the smaller asteroid and the sun.

Hooke's law states that the force, F, in a spring extended by a length x is given by
timofeeve [1]

Answer:

dimensions of k are  kg / s^2

Explanation:

F=ma   (Newton's second law)

F=-kx   (Hooke's law)

so equate both

-kx = ma

k = -ma/x

= mass * acceleration / distance  (dimensions, -1 has no dimension)

= kg * m/s^2 / m

= kg / s^2
