Diverging lens

Explanation:

Given parameters:

Power of lens = -2.0D

Unknown:

Focal length = ?

Solution:

The power of lens is the reciprocal of the focal length;

P = $\frac{1}{f}$

where f is the focal length

f = $\frac{1}{P}$ = $-\frac{1}{2}$

The lens is a diverging lens

All of the planets and their satellites orbit the Sun in the same direction, and all their orbits lie near the same plane. True

MissTica

Answer:

True

Explanation:

The Sun rotates in the counterclockwise (CCW) direction when seen from its north pole. Since, the planets revolve around the Sun because of its gravity, the revolution of all the planets and their moons as seen from the north of the Sun is in CCW direction.

In fact most of the solar system bodies rotate in the same direction that is CCW. Some major exceptions to this are Venus and Uranus.

Almost all the planets and moons were made from the planetary disk around the Sun. Thus, they lie nearly in the same plane.
