When you are pushing an object up an inclined plane, the object is gaining gravitational potential energy as it is gaining height. The kinetic energy of the object decreases and converts into that potential energy as you go up. When you have stopped, all of the kinetic energy of the object has fully been converted to gravitational potential energy.
Answer:
Explanation:
In an elliptical orbit , the angular momentum of the planet remains constant because velocity of planet makes a right angle to the direction to the star .
mvr = constant .
mv₁r₁ = mv₂r₂
v₁r₁ = v₂r₂
v₁ x 21 = 38 x 75
v₁ = 135.71 km/s .
Yes, they seem right to me.
Answer:
The speed is 
Explanation:
From the question we are told that
The mass of the first skater is 
The final speed of the first skater is 
The mass of the second skater is 
According to the principle of linear momentum conservation
Here 
Since they they started from a stationary position
So
While
substituting values
So 
=>
<span>Which color in the visible spectrum has the highest frequency?
The color in the visible spectrum that has the highest frequency is the
violet.
</span>
Violet waves have the most energy of the visible spectrum.
Remember: <span> c=fλ</span>
Therefore: <span> f=<span>c/λ</span></span>
Here c is the speed of light in a vacuum.
So:
As wavelength decreases, frequency increases and, as <span>E=hf</span>, where h is constant (Planck's constant), so does the energy that the waves carry. Waves with a short wavelength have the most energy.
<span>Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter - roughly half that.
</span><span>Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.</span>
