The velocity of a ball changes from ‹ 6, −6, 0 › m/s to ‹ 5.84, −6.32, 0 › m/s in 0.04 s, due to the gravitational attraction of the Earth and to air resistance. The mass of the ball is 110 grams. (a) What is the acceleration of the ball? = $$ (m/s)/s (b) What is the rate of change of momentum of the ball? d/dt= $$ (kg · m/s)/s (c) What is the net force acting on the ball? net= $$ N

1. A frictionless and massless piston-cylinder device initially contains 1 kg of H2O with a specific internal energy u of 1200 kJ/kg. Heat is added through a constant pressure process at 5 MPa to the system until the specific enthalpy h is 3666.5 kJ/kg. a. Find the change in specific internal energy u in kJ/kg, b. Find the heat added to the system assuming no heat losses to the surroundings and c. Draw the T-v diagram.

Use KCL and Ohm's law to determine the current through each of the resistors R4, R5, and R6 in the given figure. Assume v<sub>s</sub> = 10 V, R<sub>1</sub> = 100 ?, R<sub>2</sub> = 200 ?, R<sub>3</sub> = 50 ?, R<sub>4</sub> = 95 ?, R<sub>5</sub> = 95 ?, and R<sub>6</sub> = 95 ?. Since the three resistors must have equal currents, I<sub>95</sub> ? is ____ mA. (Round the final answer to two decimal places.)
