What does an electromagnet do?
butalik [34]
An electromagnet is a device that sends electricity through a coil of wire to produce a magnetic field. This leads to a magnet that can be controlled - turned on and off with the flip of a switch, or increased or decreased in strength. The coils are often wrapped around a regular magnet to make it stronger.

Infrasounds _____.
LiRa [457]

Infra sounds are sounds with frequencies below 20 Hz.The popular concept that infra sounds are in audible holds false

Explanation:

  • Some example of Infrasounds  are- some animals such as whales, elephants and giraffes which  communicate with each other  using infrasound over long distances.
  • Various natural phenomenon such as Avalanches, volcanoes, earthquakes, ocean waves, water falls and meteors also generate infrasonic waves
  • Infrasound, is sound that is lower in frequency than 20 Hz or cycles per second.
  • Even the human body can generate mechanical vibrations at very low frequencies, which are known as the  infrasonic waves. Such low-frequency vibrations/infrasonic waves  are produced by physiological processes—such as heartbeats, respiratory movements, blood flow in vessels, and other processes.

A 2150 kg satellite used in a cellular telephone network is in a circular orbit at a height of 780 km above the surface of the e
Tom [10]

Answer:

a)F=16741.9N

b)\frac{F}{W}=0.795

Explanation:

The gravitational force on the satellite is calculated with Newton's Gravitation Law:

F=\frac{GMm}{r^2}

Where M=5.97\times10^{24}kg is Earth's mass, m=2150kg is the satellite mass, r=R+h is the distance between their centers, where h=780000m is the height of the satellite (from Earth's surface) and R=6371000m is Earth's radius, and G=6.67\times10^{-11}Nm^2/kg^2 is the gravitational constant.

a) With these values we then have:

F=\frac{GMm}{r^2}=\frac{(6.67\times10^{-11}Nm^2/kg^2)(5.97\times10^{24}kg)(2150kg)}{(6371000m+780000m)^2}=16741.9N

b) And the fraction this force is of the satellite’s weight <em>W=mg</em> is:

\frac{F}{W}=\frac{GMm}{mgr^2}=\frac{GM}{gr^2}=\frac{(6.67\times10^{-11}Nm^2/kg^2)(5.97\times10^{24}kg)}{(9.8m/s^2)(6371000m+780000m)^2}=0.795
