According to Lenz’s law, the induced current itself creates a magnetic field to oppose the change in the external magnetic field.
Using the right hand rule, the clockwise current creates a magnetic field vertically downward.
By Lenz’s law, the created magnetic field points downward in response to...
if the external magnetic field points upward and is increasing in strength...
or points downward and is decreasing in strength.
We are told the external field is increasing in strength, so its direction must be vertically upward.
initial velocity = 0 = v₍i₎
final velocity = ? = v₍f₎
t = 12 sec
Acceleration = 4m/s²
First we have to find the distance d, for this we use the
formula,
D = v₍i₎t + 1/2at²
D = 0(12) + ½ (4)(12)²
Distance = d = 288 m
Now to find the Vf use the formula,
V₍f₎² = v₍i₎² + 2ad
V₍f₎² = (0)2 + 2(4)(288)
V₍f₎² = 2304
V₍f₎ = 48 m/s
so the velocity at the end of 12 sec is 48 m/s

The answer is A. Mixtures can be separated by physical means.
Mixtures can be separated through physical means while pure substances cannot be separated through physical means. Pure substances form compounds which are chemically bonded and can be separated through chemical means.
The majority of pelagic sediments are Biogenous
