A laser pulse takes 2.56 seconds to travel from Earth to the Moon and return. Use this to calculate how far away the Moon is. Ho
Deffense [45]

Answer:

x = 3.84\times 10^{5}\,km

This delay affect conversations in the sense that recipient will be receive the message just 2.56 seconds after the message was sent.

Explanation:

The laser pulse has an ondulatory nature as electromagnetic wave, which can travel in the void. Speed of light is constant and distance between Earth and the Moon is:

x = 0.5\cdot c\cdot \Delta t

x = 0.5\cdot (3\times 10^{5}\,\frac{km}{s})\cdot (2.56\,s)

x = 3.84\times 10^{5}\,km

This delay affect conversations in the sense that recipient will be receive the message just 2.56 seconds after the message was sent.

A projectile is fired straight upward from earths surface with a speed c given by: v^2= GM/2R. Where M is the mass and R is the
Scilla [17]

Answer:

4R/3

Explanation:

r = Distance from the surface of the Earth

R = Radius of Earth

G = Gravitational constant

M = Mass of Earth

m = Mass of satellite

v²= GM/2R

Loss of Kinetic energy is equal to Gain in potential energy

\frac{1}{2}mv^2=\frac{GMm}{R}-\frac{GMm}{r}\\\Rightarrow \frac{1}{2}m\frac{GM}{2R}=GMm\left(\frac{1}{R}-\frac{1}{r}\right)\\\Rightarrow \frac{1}{2}\frac{1}{2R}=\frac{r-R}{Rr}\\\Rightarrow \frac{1}{4}=\frac{r-R}{r}\\\Rightarrow r=4r-4R\\\Rightarrow -3r=-4R\\\Rightarrow r=\frac{4}{3}R

∴ The farthest the projectile reaches from the center of the earth is \mathbf{\frac{4}{3}R}
