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.

A student put her ear on one end of a long piece of lead. She asked her friend to
Ludmilka [50]

1) The length of the lead is 1700 m

2) The frequency of the wave is 400 Hz

Explanation:

1)

The wave in this problem is a sound wave, which is produced by the vibrations of the particles of air. It is a type of longitudinal wave (which means that the vibrations occur back-and-forth along the direction of propagation of the wave).

The speed of a sound wave in air is approximately

v = 340 m/s

In this problem, the sound wave is heard after a time of

t = 5 s

after the shot. Therefore, the distance travelled by the wave in this time (and therefore, the length of the lead) is

d=vt=(340)(5)=1700 m

2)

The frequency of a wave is the number of complete cycles made by the wave in one second.

For the wave in this problem, we are told that the wave has 2000 whole wavelengths in 5 seconds: this means that the wave completes 2000 cycles in 5 seconds. Therefore, we can find the frequency by setting up the following proportion:

\frac{2000}{5}=\frac{x}{1}

where x is the number of cycles made in 1 second. Solving for x,

x=\frac{2000\cdot 1}{5}=400 s^{-1}

Therefore, the frequency of the wave is

f=400 Hz

Which sphere has the longest gravitational potential energy?
sveticcg [70]
Gravitational potential energy is the higher it us above the ground the more gravitational potential energy it holds.Sphere 2 says it has three times the mass of sphere 1. Therefore the answer is Sphere 2 since it was raised three time the mass of sphere 1. and the rest of the answer choices dont make sense.
