(express your answer in the proper SI unit and without scientific notation)QUESTION 3How much electric force (in N) exist between two electron separated by a distance of 5.0 x 1015 m?The answer (in fundamental Sl unit) is(type the numeric value only)QUESTION 4(COLLAB Gauss's Law for Mass) Journey through the Center of the Earth. A 1024.kg blue ball is dropped from an initial z-position of 2.9 x 106 mthrough the center of a planet with radius 6 x 106 m. If the mass of the planet is 32.1 x 1015 kg, measure the displacement of the ball at time t = 7 s? QUESTION 1(10 blanks) If the gravitational potential energy of the water is equal to the increase in the internal energy of the water, compute the change in itstemperature (in Kelvin), if water drops from a height of 50 m. Assume no work is done on/by the water (C = 4184 J/kg K)Sol.Using the first law of thermodynamics:AU-Q -SinceW =ThenAU-QBut, by virtue of the problem, the internal energy is equal toAU =WhileQ =ΔΤThenh=ATΔΤ-K (2 decimal place)
