Given: Mass m = 5.00 Kg; Height h = 12 m; Time t = 15 s
Required: Power P = ?
Formula: P = Fd/t = mgh/t
P = (5.0 Kg)(9.8 m/s²)(12 m)/15 s
P = 39.2 Kg.m²/s² or
P = 39.2 J
The only common property is that both of those things are comprised of H2O.
Given that the velocity of a car increases by 40 m/s in 80 seconds, the acceleration of the car will be given by:
a=(final velocity-initial velocity)/(time)
thus;
final velocity=40 m/s
initial velocity=0
time=80 seconds
hence;
a=(40-0)/80
=0.5m/s^2
An electric current has an associated magnetic field when the flow occurs in. This is also known as magnetic effect of current which has been<span> observed and quantified by </span>Ampere's Law<span>.
</span>Meanwhile, Current is produced in a conductor when it is moved through a magnetic field because the magnetic lines of force are applying a force on the free electrons in the conductor and causing them to move. This process of generating current in a conductor by placing the conductor in a changing magnetic field is called induction<span>.

Hence, when a electric wire is placed nearby another wire carrying current, due to magnetic effect of current in the wire carrying electric current, current is induced in the wire. Hence the electric pulse and it is known as induction.
