The potential energy is 490 because
1•9.8•50=490 hope it helps!
B. a solar storm that moves across the sun's surface
Radiation is the only one that can pass through a vaccum (like space). You need a medium for conduction and convection to work. Therefore the answer is radiation.
<h2>
Answer: Both objects have charges of the same sign</h2>
When two electrically charged bodies come closer, appears a force that attracts or repels them, depending on the sign of the charges of this two bodies.
This is stated by Coulomb's Law:
"The electrostatic force between two point charges and is proportional to the product of the charges and inversely proportional to the square of the distance that separates them, and has the direction of the line that joins them"
Mathematically this law is written as:
Where is a proportionality constant.
Now, if and have the same sign charge (both positive or both negative), a repulsive force will act on these charges.
Answer:
Electricity works by getting a bunch of conductor elements together and creating a flow of electron-stealing patterns through them. This flow is called a current. Conductors need to be surrounded with insulators so the electrons can only go in one direction.
