Sphere a is attached to the ceiling of an elevator by a string. a second sphere is attached to the first one by a second string. both strings are of negligible mass. here m1 = m2 = m = 3.14 kg.(a) the elevator starts from rest and accelerates downward with a = 1.35 m/s2. what are the tensions in the two strings in newtons? t1 = nt2 =.(b) if the elevator moves upward instead with the same acceleration what will be the tension in the two strings in newtons? t1 = = .(c) the maximum tension the two strings can withstand is 92.6 n. what maximum upward acceleration (in m/s2) can the elevator have without having one of the strings /s2.

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
