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.
Why does water go higher up a straw?
Water rises up a straw due to capillary action, which is the result of adhesive forces between the water molecules and the material of the straw. This causes the water to climb up the walls of the straw, against the force of gravity.
What is it called when water rises against gravity?
Capillary action is when water rises against gravity due to the interaction between the water molecules and the surface of a narrow container, such as a straw or plant roots. This phenomenon occurs because the adhesive forces between the water and the container's surface are stronger than the cohesive forces between the water molecules.
What forces is acting when 2 people is on the sea-saw in unbalanced forces?
When two people are on a seesaw and one side is lower, the unbalanced forces are gravity acting on the people's masses. The force pulling down on one side causes it to lower while the other side rises, creating an imbalance.
Why does the liquid in the reservoir go up the tube?
The liquid rises up the tube due to capillary action, which is the ability of a liquid to flow in narrow spaces without the assistance of external forces like gravity. This occurs because the adhesive forces between the liquid and the tube are stronger than the cohesive forces within the liquid itself.
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
Why does water go higher up a straw?
Water rises up a straw due to capillary action, which is the result of adhesive forces between the water molecules and the material of the straw. This causes the water to climb up the walls of the straw, against the force of gravity.
Does the force of gravity on the rocket get less as it rises?
Yes.
What is it called when water rises against gravity?
Capillary action is when water rises against gravity due to the interaction between the water molecules and the surface of a narrow container, such as a straw or plant roots. This phenomenon occurs because the adhesive forces between the water and the container's surface are stronger than the cohesive forces between the water molecules.
What is the rising action in story?
The rising action is before the climax. There the tension rises.
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 forces is acting when 2 people is on the sea-saw in unbalanced forces?
When two people are on a seesaw and one side is lower, the unbalanced forces are gravity acting on the people's masses. The force pulling down on one side causes it to lower while the other side rises, creating an imbalance.
What are the 3 features of a rocket that affect drag?
The three features of a rocket that affect drag are its shape, surface roughness, and speed. The shape, particularly the nose cone design, influences how air flows around the rocket, impacting drag forces. Surface roughness can create turbulence, increasing drag by disrupting the smooth airflow. Lastly, as the rocket's speed increases, drag typically rises due to the increased air resistance encountered at higher velocities.
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
