It means that the potential difference between the metal can and the little button on top of the battery is about 1.5 volts.
That's strictly the result of the chemicals in the battery, and has nothing to do with its size. If a battery as big as a house has the same chemistry inside that the AA has, the big one will also have 1.5 volts between its terminals. (But it'll run your flashlight much longer than the AA will, before it runs down.)
Answer:
Acceleration = 9.8 m/sec2
Explanation:
We know that the acceleration due to gravity is 9.8 m/sec2 near the surface of earth.
Remember that the gravity is always affecting everything on earth at every instant, even the rock at the very top of it's trajectory. It doesn't mind if the velocity is zero for an instant or if there's air resistance, the gravity force is there, and always aims towards the center of the earth.
So for all the trajectory of the rock, gravity is 9.8 m/sec2
The combination of all of the forces acting on object is net force.
Answer: Q = 8.37×10^-9L/s
Explanation: since the depth of the surface is normal to the flow, ø = 90
