Answer:

4 seconds

Explanation:

Given:

v₀ = 20 m/s

v = 0 m/s

a = -5 m/s²

Find: t

v = at + v₀

0 m/s = (-5 m/s²) t + 20 m/s

t = 4 s

A coil lies flat on a level tabletop in a region where the magnetic field vector points straight up. The magnetic field suddenly
Inessa [10]

Answer:

c. Clockwise

Explanation:

As per FARADAY's the rate of change in magnetic flux linked with a coil will induce EMF in the coil and this will result the induce current in the coil.

Here we know that the direction of induced current in the closed loop is in such a way that the magnetic flux due to induced current always oppose the flux due to which it is induced

So we can say that if the flux linked with the coil will increase with time then flux of induced current will be in opposite direction to oppose the increasing flux.

So here when magnetic field becomes stronger then the induced current is in such a way that will always oppose the increasing flux of magnetic field

So we will say that correct answer will be

c. Clockwise

The direction that an induced current flows in a circuit is given by
AURORKA [14]

Answer:

Lenz's law

Explanation:

it  states that induced emf  of  different polarities induces a current whose magnetic field opposes the change in magnetic flux through the coil  in order to ensure that original flux is maintained through the coil  when current flows in it.

according to Faraday' s law of electromagnetic induction

Where -ve sign due to lenz's law

Emf is the induced voltage also known as electromotive force

N is the number of loops.

dϕ Change in magnetic flux.

dt Change in time.

What evidence would you observe if the law of conservation of mass is obeyed when mixing two solutions?​
Marianna [84]

Answer:

You should have noticed that the number of atoms in the reactants is the same as the number of atoms in the product. The number of atoms is conserved during the reaction. However, you will also see that the number of molecules in the reactants and products are not the same.
