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.

The 88-lb force P is applied to the 210-lb crate, which is stationary before the force is applied. Determine the magnitude and d
Marina86 [1]

Answer:

F=-88Ib

Explanation:

From the question we are told that:

Force P=88Ib

Mass of crate M_c=210Ib

Generally the equation for Frictional force F is mathematically given by

Friction\ force (f) = friction\ coefficient\ (u) * Normal\ reaction (N)

F=u*N

with \mu =0.47

F=98.7Ib

Therefore since Static Friction supersedes applied force body remains at rest.

Frictional force =88Ib (negative)

F=-88Ib

Is electrical conductivity?
expeople1 [14]

Answer:

can't tell if this is question, it is not written correctly

Explanation:

Electrical conductivity is the measure of a material's ability to allow the transport of an electric charge. Its SI is the siemens per meter, (A2s3m−3kg−1) (named after Werner von Siemens) or, more simply, Sm−1. It is the ratio of the current density to the electric field strength.
