What's the Coulomb's law?

Answers

Answer 1
Answer:


In layman's term:
like charges don't attract while opposite charges doelectrostatic forces between point A( which is charged) and point B (which is also charged) are proportional to the charge of point A and point B. there is also something else about this  law that I don't quite remember.

___________________________________________________

Here is the formula:

F = k x Q1 x Q2/d^2

What the formula means:

F=force between charges

Q1 and Q2= amount of charge

d=distance between these two charges

k= Coulombs constant (proportionally constant)

________________________________________________

I think that about covers it and hopefully this helped.

Answer 2
Answer: Coulomb's law states that if you place two particles of respective charges q_1,q_2 at a distance d from each other, one will exert the following force on the other :

\vec{F}=k(q_1q_2)/(d^2)\vec{u} where \vec{u} is a unit vector from the first charge to the other and k is a positive constant.

A direct consequence of this is that two charges of same sign repel each other, while two charges of opposite signs attract each other.

A strand of 10 lights is plugged into an outlet. How can you determine if the lights are connected in series or parallel? A) Unscrew one light. If the other lights stay on, it's a series circuit. B) Unplug the strand. If the first light stays on, it's a series circuit. C) Unscrew one light. If the other lights turn off, it's a series circuit. D) Cut the strand in half. If the plugged in half stays on, it's a series circuit

Answers

Answer: C) Unscrew one light. If the other lights turn off, it's a series circuit.

Explanation:

In a series circuit, all the components in the same path. The current in the entire circuit is same. The voltage drop across each component is different. If one component does not work, the entire circuit breaks and other components also stop working. On the other hand, in a parallel circuit, voltage drop across all the components is equal. Trouble in one component does not effect other components.

Hence, to check whether the lights are connected in series or in parallel, one light should be unplugged and if the other lights still work, it means they are connected in parallel otherwise in series. Thus, correct option is C) Unscrew one light. If the other lights turn off, it's a series circuit.

this answer is c because a series series circuit only has one path unlike a parallel circuit which has multiple circuits.

How do simple machines make work easier? A.
They add energy to the work.

B.
They increase the force needed to work.

C.
They reduce the speed of work.

D.
They increase the distance over which a force is applied.
C.?

Answers

Answer:  D.  They increase the distance over which a force is applied.

Explanation:

Simple machines are basic mechanical devices which make our work easier like lever, pulley, wheel and axle, inclined plane, wedge and screw. The magnitude of the force or direction is altered using a simple machine. They increase the distance over which a force is applied. They use mechanical advantage to increase the magnitude of the force.
