What else can I help you with?
a proton and electron have the same kinetic energywhich has longer wavelength?
the electron would have the longer wavelength b/c the proton has more momentum and λ=h/p (λ is wavelength, h is planc's constant and p is momentum)
What is the law of momentum?
The law of momentum states that the total momentum of a closed system remains constant before and after a collision, as long as no external forces are present. This principle is based on the conservation of momentum, which asserts that the total momentum in a system is conserved unless acted upon by an external force.
Why ping pong ball rolls in air for longer time?
A ping pong ball rolls for a longer time in air due to its low mass and high surface area, which results in less air resistance compared to heavier or more aerodynamic objects. This lower air resistance allows the ball to maintain its speed and momentum for a longer period before coming to a stop.
Goes in dry comes out wet longer it gets the stronger it becomes?
The answer to the riddle is a tea bag. When a tea bag is placed in hot water, it starts off dry and absorbs the water, becoming wet. As it steeps longer, the flavor becomes stronger, enhancing the tea's taste.
Radiation wavelength becomes longer what happens?
When radiation wavelength becomes longer, the energy of the radiation decreases. This generally corresponds to moving from higher energy regions of the electromagnetic spectrum (e.g. ultraviolet, X-rays) to lower energy regions (e.g. infrared, radio waves). This change in energy can affect how the radiation interacts with matter and the environment.
An object is at rest. Once there is enough force to overcome the inertia of the object the longer the same force acts on the moving object the (lessergreater) its change in momentum.?
Greater. Since force is directly proportional to the change in momentum, the longer a force acts on an object, the greater the change in its momentum.
How does the force and time change the momentum?
The force acting on an object over a period of time will change its momentum. The greater the force applied or the longer it is applied, the greater the change in the object's momentum. This relationship is described by Newton's second law of motion, which states that the change in momentum is equal to the force applied multiplied by the time it is applied for.
How does a wedge change an input force?
A change can happen when a mechanical advantage increases as it becomes longer and thinner.
Why athelete has to run before taking long jump?
An athelet always runs before jumping to gain momentum.This helps in jumping higher and longer as the rate of change of momentum becomes less and that is why he can jump higher and longer with the same amount of force.
How much momentum does and object have when it stops?
The Same! The statement above is true depending on what u mean. Think of it as a person running. While the person is running they have momentum ( momentum is mass times velocity). Now say they for some reason have to suddenly stop all at once, at the exact moment they stop the momentum is the same, this is why their body would jerk forward. However after that, when they were no longer moving, they would no longer have momentum, mathematically speaking that person's mass times their velocity of zero is then zero.
Which causes a bigger change in momentum of an object a big force for a short time or a small force for a longer time?
A big force applied for a short time causes a bigger change in momentum compared to a small force applied for a longer time. This is because momentum is the product of force and time, so a larger force produces a greater change in momentum in a shorter duration.
When a ball is hit with a given force why does contact over a long time impart more speed to the ball?
When the ball is in contact with the bat for a longer time, the force is applied over a longer duration, increasing the impulse and accelerating the ball to a higher speed. This is due to the impulse-momentum theorem which states that the change in momentum of an object is directly proportional to the impulse acting on it.
How a wedge changes an input force.?
A change can happen when a mechanical advantage increases as it becomes longer and thinner.
When can scientific theory be change?
whenever an experiment fails to confirm the theory it is no longer a theory ... it becomes a hypothesis
What is one way to increase the momentum of an object?
Momentum is of two kind. One is linear momentum and the other is angular momentum. Linear momentum is defined as the product of the mass and the velocity. Hence a vector quantity. To change the momentum of a given body with its mass constant, its velocity is to be changed. Velocity change could be made by changing its magnitude or direction or both. Angular momentum is the product of moment of inertial and the angular velocity. Same manner, angular momentum is also a vector quantity as angular velocity is a vector quantity. Most of us think that moment of inertia of a body about any prescribed axis is also a vector quantity. It is totally wrong as far as my approach is concerned. Moment of inertia is a scalar quantity. So to change the momentum, some force can be applied by allowing a moving body to collide with. Angular momentum can be changed by applying torque on it. Torque colloquially saying is a turning force. Moment of effective force about an axis is termed as torque.
The greatest change in momentum will be produced by a large force acting over a(n) period of time.?
The greatest change in momentum will be produced by a large force acting over a short period of time, as described by Newton's second law, F = dp/dt. A large force acting over a longer period of time would also produce a significant change in momentum, but the impact would be distributed over a greater duration.
Higher speeds require more space for a maneuver?
Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.
