We will use a video to study Faraday's law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. Specifically, we will: . 1. Examine some of the main principles behind Faraday's law.
2. Apply Lenz's law to determine the direction of the induced emf.
3. Take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field.
4. Use the horizontal scale provided to determine the speed of the coil.
5. Calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.

the plateau is likely to turn into a desert do to corrosion.

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
