Answer:

D.)it orbits near the Kepler belt

Explanation:

The Kuiper belt is an area similar to the asteroide belt extending from the orbit of Neptune to about 50 AU from the Sun. It mainly consists of icy asteroids and dwarf planets, which are rocky objects big enough to be defined as planet but that do not have enough gravity to clear their orbit from other obejcts.

Pluto was discovered in 1930 - initially it was classified as a planet, although it is much smaller than the other 8 planets of the Solar System. However, it has been recently de-classified to dwarf planet because its gravity is not enough to clear its orbit from other objects (asteroids). Pluto is located inside the Kuiper belt, so option D is correct. Other dwarf planets in the Kuiper belt are for instance Haumea and Makemake.

What average force is required to stop a 980 kg car in 9.0 s if the car is traveling at 91 km/h ?

kozerog [31]

Newton's second law of motion:
F=ma
$a = \frac{v}{t}$
You convert from km/h to m/s by dividing by 3.6:
$v = 91 \div 3.6$
$v = 25.3 \: \frac{m}{s}$
Then a is:
$a = \frac{25.3}{9}$
$a = 2.8 \frac{m}{s {}^{2} }$
Then:
F=(980)(2.8)=2744 N

stellarik [79]

The current in the wire has created a magnetic field with its north pole at the top of the rod. A magnetic field influences electric currents.

<h3>What is a magnetic field?</h3>

A magnetic field is a type of field that influences the position and direction of the electric current.

The magnetic field also refers to the one where magnetic forces act to shape an electrical current.

The only material and/or body capable of altering an electrical current in a magnetic field is the presence of another magnetic field.
