Answer:

The display of dawn and the reflection of radio waves back to Earth result from the ionosphere.

Explanation:

Ionosphere is one of the layers of the earth's atmosphere, characterized by containing charges of ions and electrons and covering between 60 km and 500 km altitude. The ionosphere - also known as thermosphere - is located between the mesosphere and the exosphere. This layer of the atmosphere is constantly ionized due to the radiation it receives from cosmic and solar rays. This layer is responsible for the display of dawn and the reflection of radio waves back to Earth.

A cyclist rides 6.2 km east, then 9.28 km in a direction 27.27 degrees west of north, then 7.99 km west. A. What is the magnitud
Pani-rosa [81]

Answer:

Explanation:

given,

cyclist ride  6.2 km east and then 9.28 km in the direction of 27.27° west of north and then 7.99 km west.

vertical component = 9.28 cos∅

                                = 9.28 cos 27.27°

                                = 8.24 km

horizontal axis component = 9.28 sin ∅

                                             = 9.28 sin 27.27°

                                             = 4.5 km

distance of the final point from the origin

                            = 7.99 -(6.2-4.5)

                            = 6.29 km

displacement

d = \sqrt{6.29^2+8.24^2}

d = 10.37 km

b) tan \theta = \dfrac{6.29}{8.24}

θ = 37.36°

A planet orbits a sun in a clockwise elliptical orbit as shown in the diagram below
STatiana [176]

Answer:

Greatest gravitational energy is at "C".

The planet has to do work "against" the field to get to "C".

Also, if m v R (angular momentum) is constant then as R increases v must decrease for this term to be constant and KE = 1/2 M v^2  must decrease also to get to point C.
