kozerog [31]

Answer:

Energy

A wave is a disturbance that carries energy from one place to another through matter and space.

Explanation:

A wave can be defined as a form of disturbance that carries energy from one place to another through matter and space.

The energy of wave depends on the frequency of the wave and the wavelength (lambda) of that particular wave.

Mathematically,

V = f × lambda

Light requires 4.5 years to travel from the nearest star to earth. If we could travel there in a spaceship going 90% of the spee

weeeeeb [17]

Answer:

Time according to earth clock (T0) = 0.22 years (Approx)

Explanation:

Given:

Time taken by light = 4.5 years

Time taken by ship = 5 years

Speed of light = c

Speed of ship (v) = 90% of c = 0.9c

Find:

Time according to earth clock (T0) = ?

Computation:

Time dilation is ,

$T(Difference) = \frac{T0}{\sqrt{1-\frac{v^2}{c^2} } }\\\\ (5-4.5)= \frac{T0}{\sqrt{1-\frac{(0.9c)^2}{c^2} } }\\\\ 0.5=\frac{T0}{\sqrt{1-0.81} }\\\\T0 =0.2179$

Time according to earth clock (T0) = 0.22 years (Approx)

tourist travels 1500 miles using two planes. The second plane averages 50 miles per hour faster than the first plane. The touris

Genrish500 [490]

Answer

given,

tourist travels = 1500 miles

second plane averages 50 miles per hour faster than the first plane.

x = y + 50

The tourist uses the slower plane for the first 500 and the faster plane for the next 1000 miles.

total flying time = 6.5 hours

$\dfrac{500}{y} + \dfrac{1000}{x} = 6.5$

$\dfrac{500}{y} + \dfrac{1000}{y + 50} = 6.5$

$\dfrac{500(50 + y)+ 1000 y}{y(y + 50)} = 6.5$

$25000 + 600 y = 6.5 y^2 + 325 y$

$6.5 y^2 - 275 y - 25000 = 0$

on solving equation

y = 86.67 mile/hr

x = 86.67 + 50

x = 136.67 mile/hr
