The charge entering the positive terminal of an element is q = 5 sin 4 π t mc while the voltage across the element (plus to minus) is v = 3 cos 4 π t v (a) find the power delivered to the element at t = 0.3 s

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
