Answer: Planets revolve around the Sun

Explanation: The heliocentric model implies that all the planets of the solar system, therefore, the Earth, together with their satellites orbit the Sun. This means that the Sun is the center of the solar system, not the Earth as it was believed to be under the influence of the teachings of the Church in the Middle Ages. The reason for this is that gravitational force acts between celestial bodies as a consequence of the huge masses that celestial bodies have. Since the Sun has a much larger mass than all the planets and satellites of the solar system, the greatest influence, that is, the attractive force, acts from the Sun, and all planets therefore revolve around the Sun. Also, the Earth has a larger mass than the Moon, so the Moon orbits the Earth, but together with the Earth it orbits the Sun because of the huge mass of the Sun.

An ant can travel approximately 30 meters per minute. How many meters could an ant move in 45 minutes.

Nastasia [14]

Answer:

From what I see, it's saying that every minute, the ant can move 30 meters. So how many meter would it move in 45 minutes?

30 meters = 1 min

x meters = 45 min

1 min x 45 = 45 min

30 meters x 45 = 1,350 meters

So, I believe the answer would be 1,350 meters.

hope this helps. :>

Why do the waves have different speeds in different layers of Earth's surface?

Genrish500 [490]

Answer:

Material's density

Explanation:

Seismic waves travel at different rates of speed based on a material's density. Hopefully, you understand that the Earth has three main layers: the crust, mantle, and core. Earthquake waves move faster through solids.

2. As a pendulum swings, its energy is constantly converted between kinetic

Alex

Answer:

at point F

Explanation:

To know the point in which the pendulum has the greatest potential energy you can assume that the zero reference of the gravitational energy (it is mandatory to define it) is at the bottom of the pendulum.

Then, when the pendulum reaches it maximum height in its motion the gravitational potential energy is

U = mgh

m: mass of the pendulum

g: gravitational constant

The greatest value is obtained when the pendulum reaches y=h

Furthermore, at this point the pendulum stops to come back in ts motion and then the speed is zero, and so, the kinetic energy (K=1/mv^2=0).

A) answer, at point F
