The weight of a person is 500N and his foot imprint is 0.5 m square. Calculate the total pressure exerted by a person when he stands on both feet.

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

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
