If the sphere is positively charged, the positive rod is repelled by the sphere while the negative rod is attracted by the sphere.
<h3>What is an electrical charge?</h3>
An electrical charge can be positive or negative. From the laws of electrostatics, unlike charges attract while like charges repel. As such the effect observed when the rods are individually brought near the sphere will decide the charge on the sphere.
If the sphere is neutral, there is no effect observed when each rod is brought near the sphere. If the sphere is positively charged, the positive rod is repelled by the sphere while the negative rod is attracted by the sphere.

Answer:
A. the tendency of moving objects to stay in motion
Explanation:
just did it on ap3x
With only two resistors in parallel, it's relatively easy
to calculate their combined equivalent resistance.
R = (their product) / (their sum)
= (18Ω x 23.5Ω) / (18Ω + 23.5Ω)
= (423Ω²) / (41.5Ω)
= 10.2 Ω
Answer:2.541
Explanation:
Well , Potential Energy = mgh
m=mass = 82
g=acceleration of gravity=9.80m/s^2
h=what we are looking for
PE=mgh
PE/(mg) = h
Substitute in the values:
1970/(82 x 9.8) = h 2.541
