When a rocket rises what is the reaction force?
A rocket in space operates off the expelled mass, from the conservation of momentum, dmv/dt = mdV/dt + Vdm/dt =0, The rocket is acceleration is mdV/dt = -Vdm/dt. The exhaust is Vdm/dt which is the force pushing the rocket forward as the exhaust goes out.
What causes your chest size to change when you breathe in?
The air pressure rises in your chest
How do rockets move?
a rocket moves when gasses expell from the back causing the rocket to move in the opposite direction a rocket moves when gasses expell from the back causing the rocket to move in the opposite direction
How does heat make paper spiral spin?
Heat causes air to rise by convection. As the air rises it applies pressure to the underside of the blades. This causes the paper spiral to spin.
What are two forces acting on a bubble as it rises through a liquid?
1) Weight in the downward direction 2) Upthrust due to the displaced liquid
What do Cohesion and Adhesion have to do with Capillary action?
The liquid rises up due to the forces of adhesion between the capillary and liquid.. It rises till the extent when adhesive and cohesive forces and external forces balance each other...

What is the main advantage of a multistage rocket?
that the total weight of the rocket is greatly reduced as the rocket rises
Does the force of gravity on the rocket get less as it rises?
Yes.
The Earth's mantle is made up of very hot material that rises to the top of the mantle cools then sinks reheats and rises again constantly repeating the cycle. This action which causes the Earth's cru?

As a rocket rises its kinetic energy changes. At the time the rocket reaches its highest point most of the kinetic energy of the rocket has been and mdash?
When an object - rocket or otherwise - rises, its kinetic energy gets converted to gravitational potential energy. At its highest point, if it rises directly upwards, all the kinetic energy will be converted to gravitational potential energy. However, its movement may also have a sideways component; in that case, not all the kinetic energy is converted to potential energy.
What is the rising action in story?
The rising action is before the climax. There the tension rises.
What causes us to think that heat rises?
Because of convection: heat rises and cold sinks
What is a plot's rising action?
it presents the tension the essential confusion of the story which usually involves key characters
What causes supply to grow as price rises?
law of supply
Why does oil in the wick of an oil lamp rises?
due to capilliary action
Capillary action occurs when water rises from the water table into?
The capillary fringe
