A fast ferry takes 4 hours to cross a lake an average speed of 108km/h. On a particular day, it travaled at an average speed of 94km/h for 4 hours. What was the remaining distance?

Remaining distance will be 56 km

Explanation:

As we know that the distance traveled is given as the product of speed and time

So we will have

so total distance to cross is given as

Now if it moves with speed of 94 km/h for 4 hours then distance covered by it

Remaining distance is given as

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
