Planets in our solar system do not revolve around the sun in perfect circles. Their orbits are more like ovals that scientists describe as which of the following? A.
revolutionary
B.
rotational
C.
periodical
D.
elliptical

Answers

Their orbits are more like ovals that scientists describe as elliptical.

Orbit

It is a regular, repeating path, which one object in space takes around another one.

The comets, planets, asteroids, and other objects in the solar system orbit the Sun.

The majority of the objects orbiting the Sun move close or along to an imaginary flat surface. This imaginary surface is known as the ecliptic plane.

All the orbits are elliptical that shows that they are ellipse, identical to an oval.

The planets in the solar system do not revolve around the Sun in perfect circles, their orbits are more like ovals, which are illustrated by scientists as elliptical.

Thus, the correct answer is option D.

The correct answer of the given statement above would be option D. The planets in our solar system do not revolve around the run in perfect circles. And their orbits are more like of a shape of an oval in which it is described as elliptical. This is according to the Law of Orbits by Kepler.

A 0.100-kilogram apple falls from a height of 1.50 meters to 1.00 meters. Ignoring frictional effects, what is the kinetic energy of the apple at this height?

Answers

Answer:

The kinetic energy of the apple at this height is 0.49 J.

Explanation:

Mass of apple, m = 0.1 kg

It falls form a height of 1.5 meters to 1 meters. We need to find the kinetic energy of the apple at this height. As the apple is falling, the decrease in potential energy is equal to the increase in kinetic energy. Using the conservation of energy as :

$E_k=-\Delta E_p$

$E_k=-mg\Delta h$

$E_k=-0.1* 9.8* (1-1.5)$

$E_k=0.49\ J$

So, the kinetic energy of the apple at this height is 0.49 J. Hence, this is the required solution.

before the fall, at 1.50 m, all the energy is potential and none is kinetic.

As it's falling the apple has both kinetic and potential energies. The decrease in potential energy is equal to the increase in kinetic energy

KE = -ΔPE
= -mgΔh
= -(0.100 kg)(9.81 m/s²)(1.00 m - 1.50 m)
= 0.491 J
