Two people are paddling a canoe downstream with a speed of 3.5 km/h relative to the river. If the river is flowing at 22 km/h, how long will it take
them to reach the canoe dock 25 km away?
A. 1.4 h
B. 1.2 h
c. 1.6 h
D. 1.0 h

What is a good example of instantaneous speed

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
