A. 0.5 hz because frequency os the amount of waves that pass per one second.

Answer:

b. 2Hz

Explanation:

Frequency is defined as the number of wavelengths passing a particular point per second.

If 3 crests pass a point in two seconds, then we know that 6 crests pass the point per second.

Therefore 2 wavelengths pass the point per second, and hence the frequency of the wave is 2Hz.

Increasing the amount of current that flows through a wire ______ the strength of an electromagnet

Anestetic [448]

Electromagnet is in form of solenoid

and the magnetic field due to solenoid is given as

$B = \mu_0 n i$

here

i = current in the loop

so when we increase the current in electromagnet the magnetic field of the solenoid will increase

this will increase the strength of the electromagnet

so the answer would be

<em>INCREASE</em>
