For an electromagnetic wave described by b = 8 × 10–6 sin(5000πx – 3 × 1011πt), where b is in tesla, x is in metre and t is in second, the incorrect parameter is.

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

Asystem containing an ideal gas at a constant pressure of 1.22×10^5 pa gains 2140 j of heat. during the process, the internal energy of the system increases by 2320 j. what is the change in volume of the gas?

What is the power rating of the lightbulb if 3.0 a flow through it when connected to a 15 v battery
