The force between two magnetic poles will increase as their separation is increased. true or false?

Answers

Answer 1

Answer: False, because the force between two charged objects decreases as distance between them increases, as per the universal magnetic force law:

F = kq1q2 / r^2, where F is the force, r is the distance between the objects, k is the universal magnetic constant, and q1 and q2 are the unit charge per unit mass values,

Answers

Answer: The correct answer is "force".

Explanation:

Magnet has two poles: South pole and North pole.

Magnetic field lines are the surrounding around the magnet in which magnetic force can be experienced.

Like poles repel each other. There is force of repulsion between like poles. Unlike poles attract each other. There is force of attraction between the opposite poles.

Magnetism is a force. It is not a power. The power is the rate of doing work.

Magnetism is not a form energy.

Therefore, the correct option is (A).

your answer would be a, it is a force.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:

The mechanical advantage of a lever can be calculated.

Explanation:

If the length of the effort arm and the length of the resistance arm are given we can calculated the mechanical advantage of a lever. It is also defined as the ratio of output force to the input force. Mathematically, it is given by :

$MA=(F_o)/(F_i)$

Where

$F_o$ is the output force

$F_i$ is the input force

A lever is a simple machine in which there is a Plank that is free to free to rotate around a pivot. So, the correct option is (a) "the mechanical advantage of a lever can be calculated".

Answers

Answer:

$\Delta t = (\Delta x)/(v) \n\n$

Explanation:

Given the expression $v\:=(\Delta x)/(\Delta t)$ , we are to find the value of Δt from the expression. To find Δt, we will make Δt the subject of the formula from the given expression as shown;

$v\:=(\Delta x)/(\Delta t)\n\ncross\ multiply\n\nv*\Delta t = \Delta x\n\nDivide \ both\ sides \ of\ the \ resulting \ equation \ by \ v\n\n(v*\Delta t)/(v) = (\Delta x)/(v) \n\n\Delta t = (\Delta x)/(v) \n\n$

Hence the equivalent expression for $\Delta t = (\Delta x)/(v) \n\n$ .
