The appearance of color is a result of the absorption and reflection of certain wavelengths of light. a shirt appears a certain color because it reflects that color of light. on the other hand, a shirt appears black when it absorbs all wavelengths of light and white when it reflects all wavelengths of light.

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?
