A 120-V AC circuit has a 20.0-Ω resistor connected in series to a capacitor for which the capacitive reactance is XC = 45.0 Ω . 1. What is the phase constant?
2. What is the average rate at which energy is dissipated in the circuit?
3. If the resistance in the circuit is 25.0 Ω, what would the capacitive reactance have to be in order for the power factor to be 0.37?

concave lenses are used here. they spread the light out before it reaches the convex lens in the eye, therefore letting the image focus directly on the retina. hyperopia is known to you probably as farsightedness.

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
