Figure 1 (The Attached Image): A circuit is shown above. Assume the cell and wires are ideal. Find the voltage across the 4, R,4R resistor.
(This uses Kirchhoff's Laws)

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.

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
