Answer:
The magnitude of the voltage is and the direction of the current is clockwise.
Explanation:
Given that,
Number of turns = 9
Magnetic field = 0.5 T
Diameter = 3 cm
Time t = 0.14 s
We need to calculate the flux
Using formula of flux
Put the value into the formula
We need to calculate the emf
Using formula of emf
Negative sign shows the direction of current.
Hence, The magnitude of the voltage is and the direction of the current is clockwise.
We know that momentum = mass times velocity
So a. 720 kgm/s
The external auditory meatus, or ear canal, funnels sound to the eardrum. It is part of the outer ear.
Answer:
sound waves need a medium to travel on because the molecules of the solid liquid gas etc... it carries sound waves from one point to another. which goes for other substances sound cannot travel through the vaccum Because the vaccum has no molecules and the vibration that is needed to carry the sound waves
Explanation:
hope this helped your question!
