A 3.0-kilogram mass is traveling in a circle of 0.20-meter radius with a speed of 2.0 meters per second. what is the centripetal
1 answer:
You might be interested in
De broglie wavelength, , where h is the Planck's constant, m is the mass and v is the velocity.
Mass of hydrogen atom,
v = 440 m/s
Substituting
Wavelength
So the de broglie wavelength (in picometers) of a hydrogen atom traveling at 440 m/s is 902 pm
Answer:
The change in power is 4400 W.
Explanation:
Given that,
Power = 10 kW
Speed = 10 m/s
Increases speed = 12 m/s
Given equation is,
We know that,
The power is,
Put the value of F into the formula
We need to calculate the new power
Using formula for power
Put the value into the formula
We need to calculate the change in power
Using formula of change in power
Put the value into the formula
Hence, The change in power is 4400 W.
