What kind of charge does an object have when it has given away electrons?

Step2247 [10]

Electrons have a negative charge, so if you give away electrons, you give away negative charge, thus ending with a positive charge.

At the local playground, a 21-kg child sits on the right end of a horizontal teeter-totter, 1.8 m from the pivot point. On the l

Alja [10]

Answer:

Counterclockwise

Explanation:

We need to calculate the clocwkise and the counterclockwise torque.

The clockwise torque is the one generated by the child sitting on the right. This torque is given by:

$M_C = F d$

where

$F=mg=(21 kg)(9.8 m/s^2)=205.8 N$ is the force exerted by the child (his weight)

d = 1.8 m is the distance from the pivot point

So, the clockwise torque is

$M_C = (205.8 N)(1.8 m)=370.4 Nm$

The counterclockwise torque is the one generated by the adult pushing on the left, and it is given by

$M_A = F d$

where

F = 151 N is the force applied

d = 3.0 m is the distance from the pivot

Substituting,

$M_A = (151 N)(3.0 m)=453 Nm$

So, the net torque is

$M_A - M_C = 453 Nm - 370.4 Nm=82.6 Nm$

And since the counterclockwise momentum is greater than the clockwise one, the teeter-totter will rotate counterclockwise.
