Find the current in the 5 Ω resistor. Find the potential at b w. r.t. that at a if the 5 Ω resistor is removed and the terminals a-b are open circuited. The 5 Ω resistor removed from the circuit and the 90 V source is replaced by a 10 Ω resistor. Determine the resistance that will be measured across a-b.

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
