When work is done and a force is transferred an object must move
When red light illuminates a grating with 7000 lines per centimeter, its second maximum is at 62.4°. What is the wavelength of this light?
ans: 633nm
Answer:
33.83W/m²
Explanation:
The intensity of the speake at the surface is
I = P/A
I = 2.03W / 0.06m²
I = 33.83W/m²
Answer:
motion energy to sound energy
Explanation:
you move your hands together, then clap then, which makes a sound. Hope that this helps you and have a great day :)
Work can be defined as the energy transferred from a body to its sorroundings, the energy spent to move a body, or the energy you need to alter a charged particle, so no energy, no work; thus, the statement is true.
