The capacitors we looked at were all within their 20% tolerance window. But many were still significantly different from their advertised values. For situations that require high-precision, it is possible to buy capacitors with a much smaller tolerance (like 1%). But they are much more expensive! So they are only used where necessary. Think about some of the places capacitors are used in practice (feel free to research this as well). Give two examples of situations that might call for a higher-precision capacitor.

The movement of electrons between atoms is called an

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
