Nearly all physics problems will use the unit m/s for acceleration explain why is not the unit given as m/s as it is for speed?

In physics, Ohm's law says that current through a wire, I, is directly proportional to voltage, V, and inversely proportional to resistance, R: [ I=V/R. ] It's also true that resistance is directly proportional to the length of the wire.

The grounded conductor and the grounding conductor are one and the same conductor and perform the same function.

5. Which is not true about a wave in the open ocean? D A Water particles move in a circular path. B As the wave travels, water particles pass the energy along by moving in a circle. O C Water particles travel with the wave.

Which of these is not a way to build resilience?

How much would a 100kg man weigh on the surface of the sun where the acceleration is 274 m/s
