Ablock of mass 20 kg on a horizontal surface where uk= 0.4is pushed against an initially relaxed spring that has a force constant k = 100 n/m, compressing it 1.50 meters. it is then released, what is the maximum velocity of the mass?

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

A6.0-μf air-filled capacitor is connected across a 100-v voltage source. after the source fully charges the capacitor, the capacitor is immersed in transformer oil (of dielectric constant 4.5). how much additional charge flows from the voltage source, which remained connected during the process?

If jason ii needs 15 kw of power at 300 volts to operate, what amperage of current must flow through the cable?
