It is known that the gravitational force of attraction between two protons is much weaker than the electrical repulsion. For two protons at a distance d apart, calculate the ratio of the size of the gravitational attraction to that of the electrical repulsion. Specifically, find the magnitude of Fgravitational/Felectrical. Use the following data: k = 8.99×109 Nm2/C2 charge on one of the protons = 1.60×10-19 C G = 6.67×10-11 Nm2/kg2 mass of one of the protons = 1.67×10-27 kg.

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.
