Explanation:
Angular momentum is conserved.
I₁ ω₁ = I₂ ω₂
(½ Mr² + md²) ω₁ = (½ Mr²) ω₂
(½ (35 kg) (2.3 m)² + (84 kg) (2.3 m)²) (0.28 rev/s) = (½ (35 kg) (2.3 m)²) ω
ω = 1.624 rev/s
ω = 10.2 rad/s
Round as needed.
4. 540 Kilometers
5. 200 s

Answer:
<em>The total potential (magnitude only) is 11045.45 V</em>
Explanation:
<u>Electric Potential
</u>
The total electric potential at location A is the sum of all four individual potentials produced by the charges, including the sign since the potential is a scalar magnitude that can be computed by

Where k is the Coulomb's constant, q is the charge, and r is the distance from the charge. Let's find the potential of the rightmost charge:

The potential of the leftmost charge is exactly the same as the above because the charges and distances are identical

The potential of the topmost charge is almost equal to the above computed, is only different in the sign:

The bottom charge has double distance and the same charge, thus the potential's magnitude is half the others':

The total electric potential in A is


The total potential (magnitude only) is 11045.45 V
If you press on your arm force is applied work done is if it moves.
One answer could be if I was to press my hand on a table.
