Imagine that the satellite described in the problem introduction is used to transmit television signals. You have a satellite TV

reciever consisting of a circular dish of radius R which focuses the electromagnetic energy incident from the satellite onto a receiver which has a surface area of 5 cm2. How large does the radius R of the dish have to be to achieve an electric field vector amplitude of 0.1 mV/m at the receiver

Answer:

1-As winds rise up the windward side of a mountain range, the air cools and precipitation falls.

2-Mountains and mountain ranges can cast a rain shadow. As winds rise up the windward side of a mountain range, the air cools and precipitation falls.

3-Mountains and mountain ranges can cast a rain shadow. As winds rise up the windward side of a mountain range, the air cools and precipitation falls. On the other side of the range, the leeward side, the air is dry, and it sinks.

4-Rain shadow deserts are formed because tall mountain ranges prevent moisture-rich clouds from reaching areas on the lee, or protected side, of the range.

5-Mountains and mountain ranges can cast a rain shadow. As winds rise up the windward side of a mountain range, the air cools and precipitation falls. On the other side of the range, the leeward side, the air is dry, and it sinks. So there is very little precipitation on the leeward side of a mountain range.

6-Mountains and mountain ranges can cast a rain shadow. As winds rise up the windward side of a mountain range, the air cools and precipitation falls. On the other side of the range, the leeward side, the air is dry, and it sinks. So there is very little precipitation on the leeward side of a mountain range.

? is the change in position relative to an initial location
umka21 [38]

Answer: c. displacement

Explanation:

Let's begin by stating clear that motion is the change of position of a body at a certain time. So, during this motion, the body will have a trajectory and a displacement.

In the specific case of the displacement, it is defined as the distance in a straight line between the initial and final position (is a vector magnitude).

Therefore:

Displacement s the the change in position relative to an initial location.

the gravational force is between two objects 18 N . if the distance between them is tripled and their masses are doubled. then w
Anni [7]
F_1 =  \frac{G m_1 m_2 }{r^2 } = 18N

F_2 = \frac{G M_1 M_2 }{R^2}

R = 3r

M_1 = 2m_1

M_2 = 2m_2

F_2 =  \frac{G 2m_1 2m_2}{(3r)^2} =  \frac{4}{9} *  \frac{G m_1m_2}{r^2} =  \frac{4}{9} * 18N

A 1,160 kg satellite orbits Earth with a tangential speed of 7,446 m/s. If the satellite experiences a centripetal force of 8,95
Juli2301 [7.4K]

Answer:

8.02×10⁵ m

Explanation:

Equation for centripetal force:

F = mv²/r

Solving for r:

r = mv²/F

Given:

F = 8955 N

m = 1160 kg

v = 7446 m/s

r = (1160 kg) (7446 m/s)² / 8955 N

r = 7.182×10⁶ m

The height above the surface is:

h = 7.182×10⁶ m − 6.38×10⁶ m

h = 0.802×10⁶ m

h = 8.02×10⁵ m
