Answer: g = 10.0 m/s/s
Explanation:
For a simple pendulum, provided that the angle between the lowest and highest point of his trajectory be small, the oscillation period is given by the following expression:
T = 2π √L/g , where L = pendulum length, g= accelleration of gravity.
We can also define the period, as the time needed to complete a full swing, so from the measured values, we can conclude the following :
T = 140 sec/ 101 cycles = 1.39 sec
Equating both definitions for T, we can solve for g, as follows:
g = 4 π² L / T² = 4π². 0.49 m / (1.39)² = 10.0 m/s/s
Answer:
Explanation:
The total charge is distributed over the two objects:
The plate and the rod must have 
. So the charge transferred from the plate to the rod is:
Number of electrons:
D. Pragmatism applies to everyone, but utilitarianism is concerned with the upper class.
Answer:
four seconds
Explanation:
A player who catches the ball and is being closely guarded may hold the ball for four seconds, then dribble the ball for four seconds, then hold the ball for another four seconds, then pass, will not be in violation of this rule.
Without magnetic domains a magnet would have its magnetism. Magnetic domains are clusters of iron atoms that line up in the same direction when magnetized. When not magnetized the iron atoms scatter.
