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)
Why do large fan blades take LONGER time to stop rotating than shorter blades?
Because of larger momentum. Larger bodies have larger momentum.
What is the law of momentum?
Put in the simplest form and avoiding the math there are two parts to the law of the pendulum. The longer the chord the longer it takes for each oscilation. Increasing length by 4 times doubles the period and halves the frequency. The horizontal speed at the bottom is the same as the vertical speed would be if the body had fallen the distance from its highest point. More detailed information, inluding an experiment simulator is available at: http://www.myphysicslab.com/pendulum1.html
Why do scientists think that climate is changing?
Scientists can measure that the global temperature is rising. They know that rising temperatures will change the climate. Weather happens from day to day, but climate change takes longer, several years, or several decades before it becomes clear that it is happening. That is the situation now. Scientists know that rising temperatures will change the climate.
How can you tell if a carrot goes bad?
It usually becomes quite limp and no longer crisp when bitten into.
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 does the wavelength of electromagnetic radiation change as its frequency decreases?
It becomes longer
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
How a wedge changes a input force?
A Wedge changes an input force by a change when a mechanical advantage increases as it becomes longer and thinner.

How can a supertanker have a huge momentum when it moves relatively slow?
When you gain speed, you also gain momentum, and that's why it takes a longer amount of time to stop or speed up.
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.
Why it is not easy to whirl a hammer by a longer chain?
because with a longer chain you are giving the hammer momentum so it will take more strength to move
Why does a moving ship take longer time to stop than taken by a car when brakes are applied to both?
Ship doesn't have brakes, it has to use reverse! But in any case, the reason a ship takes longer to stop than a car is that is has more momentum. Think of momentum as something that tells you how hard it will be to stop an object. More momentum means it will be harder to stop. Momentum is equal to the mass of the object times it velocity or speed. So a ship has a lot more mass that a car and takes longer to stop.
