a long wire carries a current toward the north in a magnetic field that is directed vertically downward. what is the direction of the magnetic force on the wire?

Answers

The magnetic force on the wire will be directed to the east.

The direction of the magnetic force on the long wire carrying a current toward the north in a magnetic field directed vertically downward would be to the east.

This is because of the right-hand rule, where if you point your right thumb in the direction of the current and your fingers in the direction of the magnetic field, the resulting force would be perpendicular to both, pointing to the east in this case.
When a long wire carries a current toward the north in a magnetic field that is directed vertically downward, you can determine the direction of the magnetic force on the wire using the right-hand rule.

Step 1: Point your right thumb in the direction of the current (north).
Step 2: Curl your fingers in the direction of the magnetic field (downward).
Step 3: The direction of the force on the wire will be the direction your palm is facing.

Following these steps, the magnetic force on the wire will be directed to the east.

A shorter electromagnetic wave is _____. more powerful less powerful hotter colder

Answers

Answer

more powerful 

Explanation
Electromagnetic waves are waves that do not require material medium for propagation. For example x-rays, UV and gamma rays.

From the wave equation, V= λf, when the wavelength is short the frequency is high. 
Frequency determines the intensity of the wave. When high the frequencies are high the waves has more penetrating power, hence more powerful. 

Answer:

More powerful

Explanation:

I answered it and got it right.

If a rod attached to the approaching charge if the rod consists of "stiff" spring-like bonds for which atoms undergo small oscillations. What can we say, about these springlike bonds when the charge is first, furthest away and second, closest to the source charge

Answers

Answer: hello options related to your question is missing attached below is the missing part of your question

answer: No charge of the length of the bonds expected because the rod did not touch the charge source ( option A )

Explanation:

When the Charge is first, Furthest away and second  and closest to the source charge. The spring like bonds can be said to have No charge of the length  of the bonds expected because the rod did not touch the charge source when Furthest away the bond with charge will be less effective
