Answer:
C. 500 watts
Explanation:
power is defined as the rate of work done
When a force causes a object to move, work is being done on the object by the force.
Answer:
The answer is 4th choice. Down with a speed less than v.
Explanation:
The momentum of the person and the balloon need to cancel each other out. Momentum formula of the balloon is as following:
At the moment of t=0, the person and the balloon has the 0 speed.
When the person starts to climb on a balloon, balloon need to cancel this momentum out. We know that the balloon is more heavier than the person. So balloon need to go down with the speed of less than v.
Quartzite is produced when grains of quartz in sandstone are welded together when the rock is subjected to high temperatures. Quartzite<span> or Quarzit is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. </span><span>It is formed when a quartz-rich sandstone is altered by the heat, pressure, </span>
Hi! I think the answer is C. as we have never visited the planet we can’t be 100% sure but we can have an idea of what the planet might me like. With experimenting with the simulation it can help you get an understanding or an idea of what the planet might be like exactly like option C. I hope this helped Goodluck :)
Answer:
Explanation:
De la información dada:
La distancia total recorrida= 650 m + 500 m
La distancia total recorrida= 1150 m
La magnitud se puede calcular utilizando el teorema de Pitágoras.
a² = b² + c²
a² = 500² + 650²
a² = 250000 + 422500
a² = 672500
a =
a = 820 m
La dirección del desplazamiento resultante es la dirección noreste desde el punto de partida.
