What else can I help you with?
A 30 kg girl and a 25 kg boy face each other on friction free roller blades the girl pushes the boy who moves away at a speed of 1 0 m s the girls speed is m s?
0.55
Which laws of motion is illustrated by a man on a banca who pushes a floating log and the banca moves away from the log?
Newton's third law of motion.
What are four possible outcomes of competition?
The competition pushes both competitors to do better so both prosper.Competitor A wipes out B.Competitor B wipes out A.The competition pushes both competitors so hard that they both fail, and someone else moves in.
How does a plane moves forward in the air?
A plane flies forwards by exerting a force on the air with its wings. the air pushes back on those wings with an equal force that propels the bird forwards
A roller coaster moves 200ft horizontally it rises 135ft at angle of 30degrees above horizontal It travels 135ft at angle of 40degrees below horizontal What is displacement from start point to end?
420 feet at about an angle of -3 degrees.
A 30 kg girl and a 25 kg boy face each other on friction free roller blades the girl pushes the boy who moves away at a speed of 1 0 m s the girls speed is m s?
0.55
What type of friction pushes a skater ahead?
Kinetic friction between the skates and the ice provides the force that pushes the skater ahead. As the skater moves forward, the friction between the skates and the ice creates the necessary push for movement.
Why do wind turbines spin?
Wind turbines spin because of the force of the wind turning the blades. The wind pushes the blades, causing them to rotate. This rotation is then converted into electricity through a generator within the turbine.
How does a fan moves?
a fan moves air with fan blades.
Does a fan changes electrical energy into mechanical energy?
Yes, a fan converts electrical energy into mechanical energy by using the electrical power to rotate its blades and create airflow. The fan motor transforms the electrical energy into kinetic energy, which moves the blades and pushes air.
Where can I learn what a green power generator is?
A wind turbine is what it is. It's very tall (big) and moves (spins) and it generates power from the wind that pushes the blades. This is green since it's powered by wind, and it generates power.
If an object moves through the air what is the friction?
Fluid Friction .
What causes some of the potential energy of a moveing rollar coster to be converted to thermal energy?
Friction between the roller coaster and the track surfaces causes some of the potential energy to be converted to thermal energy. As the roller coaster moves along the track, friction generates heat due to the resistance between the surfaces, leading to a transfer of energy in the form of heat. This conversion ultimately results in a loss of energy from the system.
What energy is produced when air moves large turbines that generate electricity?
Kinetic energy is produced when air moves large turbines that generate electricity. As the air pushes the turbine blades, they spin and convert the kinetic energy into mechanical energy, which is then converted into electricity through a generator.
When cold air moves toward warm air it pushes the warm air?
I pushes the warm air upwards.
How will the velocity of the book change as it moves across a surface with no friction?
The velocity of the book will remain constant as it moves across a surface with no friction.
The friction that occures when an object moves through a fluid is called?
fluid friction
