Astronaut Rob leaves Earth in a spaceship at a speed of 0.960c relative to an observer on Earth. Rob's destination is a star sys
xxMikexx [17]

Answer:

A) 15.0 years

Explanation:

Due to the distance to the star system is in light-year units, we can compute the time by using:

t=\frac{d}{v}=\frac{14.4 l-y}{0.960}=15l-y

then, Rob will take to complete the trip about 15 light-years.

hope this helps!!

Calcula la energia potencial de Tamara que tiene una mas de 50kg y se encuentra, 80 metros arriba en el borde de un edificio
Ilya [14]

Responder:

39200 J

Explicación:

Dado:

Masa de Tamara (m) = 50 kg

Altura a la que se encuentra Tamara (h) = 80 m

Aceleración debido a la gravedad (g) = 9.8 m / s²

La energía potencial de un objeto de masa 'm' ubicada a una altura 'h' sobre el suelo se da como:

U=mgh

Ahora, conecte los valores dados y resuelva la energía potencial. Esto da,

U=50\times 9.8\times 80\\\\U=39200\ J

Por lo tanto, la energía potencial de Tamara ubicada a una altura de 80 m es 39200 J.

Find the velocity (in m/s) of a proton that has a momentum of 4.96 X 10^-19 kg.m/s.
kramer

Answer:

The velocity of the proton is 2.965*10^{8} \frac{m}{s}

Explanation:

The momentum of a particle is defined as the product of its mass by its velocity and we can calculate it using the following formula:

p=m*v Equation (1)

Where:

p: Is the momentum in kg*m/s

m: Is mass of the particle in kg

v: Is the velocity of the particle in m/s

Data known:

m= 1,6726 × 10^–27 kg : mass of the proton

p= 4.96 X 10^-19 kg.m/s.

We replace this data in the Equation (1):

4,96*10^{-19} =1.6726*10^{-27} *vv=\frac{4.9*10^{-19} }{1.6726*10^{-27} }

v=(\frac{4.96}{1.6726} )*(10^{27-19} )

v=2,965*10^{8} m/s

Answer: The velocity of the proton is 2.965*10^{8} \frac{m}{s}
