The momentum of a photon with a wavelength of 5.9*10^-7 meter is A. 8.9 * 10^26 kg*m/s B. 1.6 * 10^-19 kg*m/s C. 1.1 * 10^-27 kg*m/s D. 3.9 * 10^-40 kg*m/s-p=h/wavelength p=(6.6 X 10^ -32)/(5.9X10^-7)

Can Voltage drop across Resistances connected in Parallel, if Resistances are too low

In other words if there is too much load on the circuit (parallel) would the voltage drop? and does the Voltage Stabilizer keeps the voltage up in that situation?-Your power source ALWAYS has some kin

Please anyone help me to solve the following answer.

An air-conditioner is removing heat from a room at 20°C at a rate of 7200 kJ/h and rejecting the waste heat to the outdoors at 35°C. If the coefficient of performance of the air-conditioner is 3, the

Physics Thermal Question. Please Please Help

Please anyone help me to solve the following QUESTION? Thank you.

Hot combustion gases (assumed to have the properties of air at room temperature) enter a gas turbine at 0.8 MPa and 1500 K at a rate of 2.1 kg/s, and exit at 0.1 MPa and 800 K. If heat is lost from th

Physics / Calculating energy on a capacitor

If the potential difference across a capacitor is doubled, by what factor does the energy stored change? Knowing that U=1/2QV and U=1/2CV^2i can use one formula and get that the energy increases by a
