ArbitrLikvidat [17]

Answer:

<em>c. The astronaut does not need to worry: the charge will remain on the outside surface.</em>

<em></em>

Explanation:

The astronaut need not worry because <em>according to Gauss's law of electrostatic, a hollow charged surface will have a net zero charge on the inside.</em> This is the case of a Gauss surface, and all the charges stay on the surface of the metal chamber. This same principle explains why passengers are safe from electrostatic charges, in an enclosed aircraft, high up in the atmosphere; all the charges stay on the surface of the aircraft.

A bullet was fired from a gun. The bullet had a mass of 50g and the kinetic energy of the bullet was 25 kJ. How fast did it go?
Elenna [48]

Answer:

given \:  \\ mass \: (m) = 50g \\ kinetic \: enegy \: (k.e) = 25kj \\ velocity(v) = x \\ form \\ k.e =  \frac{1}{2}  \times MV ^{2}  \\ 25 =  \frac{1}{2}  \times 50 \times v {}^{2}  \\ 25 = 25 \times v {}^{2} \\ v {}^{2}  =  \frac{25}{25}  \\ v {}^{2}  = 1 \\ v =  \sqrt{1}  \\ v = 1ms {}^{ - }

the car it go fast with velocity 1m/s
