Answer:
Displacement is the shortest distance from your initial position to your final position. Therefore, displacement is a measurement of distance and not an "end-point."
The charge of 1 mole of proton is equivalent to 1.60217656x10^-19 coulombs. This is also called an elementary charge. Multiply that by 3 to get the net charge of three moles of protons.
Charge of 3 mol protons = 3 x 1.60217656x10^-19 = 4.81x10^-19 coloumbs
So the answer is <span>c) 4.81×10 −19 C</span>
Answer:
A.
Explanation:
momentum depends on weight and speed
Answer:
The speed maximum speed is 
Explanation:
The centrifugal force always acts on the cylinder and move away the rotating platform from the rotational axis. so the centripetal force provide by the frictional force:
Therefore
coefficient of static friction: 
mass of the cylinder: 
\
distance of the cylinder from the turntable: 
cross multiply to find v
