How long after Car B started the race wil Car B catch up with Car A? Express the time in terms of given quantities. Review Cars A and B are racing each other along the same straight road in the following manner: Car A has a head start and is a distance DA beyond the starting line at t 0. The starting line is at z-0. Car A travels at a constant speed vA Car B starts at the starting...

Solve Part D please
Learning Goal: To understand how the conservation of energy and Newton's second law can be combined to solve kinetic problems. As shown, a large globe has a radius R and a frictionless surface. A small block with mass m starts sliding from rest at the top of the globe and slides along the globe's surface. The block leaves the globe's surface when it reaches a height h above the ground. The system's geometry is shown for...

Changing Capacitance Yields a Current Each plate of a parallel-plate capacator is a square with side length r, and the plates are separated by a distance d. The capacitor is connected to a source of voltage V. A plastic slab of thickness d and dielectric constant K is inserted slowly between the plates over the time period At until the slab is squarely between the plates. While the slab is being inserted, a current runs through the battery/capacitor circuit. (Figure...

please show work.
Part C Find the dimensions [v] of speed. Express your answer as powers of length (/), mass (m), and time t View Available Hint(s) 11에 Submit There are three dimensions used in mechanics: length (), mass (m), and time (t). A combination of these three dimensions suffices to express any physical quantity, because when a new physical quantity is needed (e.g., velocity), it always obeys an equation that permits it to be expressed in terms of the...

Part C, D and E please
(6%) Problem 11: A capacitor of capacitance -8.5 F is initially uncharged. It is connected in series with a switch of negligible resistance, a resistor of resistance R-15 k2, and a battery which provides a potential difference of VB 135 V 20% Part (a) Immediately after the switch is closed, what is the voltage drop VC, in volts, across the capacitor? VC-0 Correct! 20% Part (b) Immediately after the switch is closed, what is...
