A small object begins a free-fall from a height of 22.0 m. After 1.30 s, a second small object is launched vertically upward from the ground with an initial velocity of 35.0 m/s.
At what height h above the ground will the two objects first
meet?

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

In a system, when potential energy decreases, then entropy also decreases. true false

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
