Satelite communication is only possible using

Physics

the correct answer is B) digital transmission


zimovet [89]3 years ago

None of the choices is correct.

Satellite communication is quite effective using either analog OR digital transmission.

Sound can't be used for satellite communication at all. (There's no medium to carry the sound to or from the satellite, and if there were, then the round-trip up and down through a geostationary satellite would take at least a minute at the sea-level speed of sound.)

Cellular devices can work but aren't required.

How much force is needed to accelerate a 9760 kg airplane at a rate of 4.6 m/s^2
seropon [69]
Assuming air resistance / friction is negligable:

force = mass × acceleration

f = m × a
f = 9760 × 4.6
f = 44896N

f= 45kN (2 sig fig)

I hope this helps. If you have any questions, feel free to ask

At what type of plate boundary is lithosphere created?
zloy xaker [14]

Answer:

divergent

Explanation:

When two plates are moving away from each other, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the Earth and erupts to form new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges.

A potato is launched from the ground at an 73 degree angle with a velocity of 48 m/s.
Wittaler [7]

Answer:

107.4 meters

Explanation:

gravity is 9.8m/s^2

max height = (velocity squared times sin squared angle) ÷ ( speed of gravity times 2 )

max height = (48 squared times sin of 73 squared) ÷ ( 9.8 times 2 )
