acceleration of rocket is given here as
now we know that
now integrating both sides
here since its given that rocket will accelerate for t = 10 s
so here we have
so after t = 10 s the speed of rocket will be 130 m/s upwards
Answer:
Yes
Explanation:
p = momentum of photon
E = energy of photon
c = velocity of light
Units of p = kg m /s
Units of E = kg m^2 / s^2
Units of E / p = {kg m^2 / s^2} / {kg m /s} = m/s
It is the unit of speed, so by the division of energy to the momentum, we get the speed. yes it is correct.
Answer:
If there is any sheets or padded material in this room you can cover the window, you could turn off all the lights if there is a light switch in the room, you could try to bring a bright flashlight in and shine it into the other room(try to annoy the person watching you so they leave), act really boring and hopefully make the other person lose interest.
Explanation:
(hint) If you actually get in a situation like this place your fingernail against the mirror or glass you think could possibly be a one-way mirror. If there's a gap between your nail and the mirror, it's most likely a genuine mirror :)
The formula for kinetic energy is
. Thus, the equation for velocity is
.
