Answer:

Explanation:

Positive values for position indicate that the object is in front of the starting point and negative values tell us that the object is behind the starting point. (time = 9.5, position = 0) the object is at the starting point.

At what speed must a 0.6 kg stone be thrown in order that it has a relativistic mass of 0.76 kg? (c = 3.00 x 10^8 m/s) A) 0.6976

soldier1979 [14.2K]

Answer:

The speed of the stone is 0.6138 c.

(B) is correct option.

Explanation:

Given that,

Mass of stone m= 0.6

Relativistic mass = 0.76

We need to calculate the speed

Using formula of rest mass

$m_{r}=\dfrac{m_{0}}{\sqrt{1-\dfrac{v^2}{c^2}}}$

$v^2=(\dfrac{m_{0}^2}{m_{r}^2}-1)c^2$

Put the value into the formula

$v^2=(\dfrac{0.6^2}{0.76^2}-1)\times c^2$

$v=\sqrt{0.37673c^2}$

$v=0.6138c$

Hence, The speed of the stone is 0.6138 c.

How many seconds would it take a radio wave to travel from the planet Venus to

xz_007 [3.2K]

Answer:

La distancia media de Venus al Sol es de 108.159.260,51 Km

La distancia media de la Tierra al Sol: 149.597.870,691 Km

La diferencia entre una y otra distancia media te darÃ¡ el promedio de distancia de la Tierra a Venus: 41.438.618,181 Km.

Siendo la velocidad de la luz: 299.792,458 Km / seg

Divides: 41.438.618,181 Km / 299.792,458 Km / seg = 138,22433 segundos

138,22433 seg / 60 seg = 2,30374 minutos

Este tiempo es el que tarda la onda de radio en viajar del planeta Venus a la Tierra.

La velocidad de la onda de radio se conviene en considerarla igual al de la velocidad de la Luz en el vacÃo.
