In the netherlands there is an annual ice-skating race called the "tours of the eleven towns" the total distance of the course is 2.00*10 squared km and the record time is 5 hours, 40 minutes, and 37 seconds. calculate the average speed for the record time.

The average speed for the record time is 9.78 m/s.

Explanation:

Given that,

Total distance

Time

We need to calculate the average speed for the record time

Using formula of the average speed

Where, D = total distance

T = total time

Put the value into the formula

Hence, The average speed for the record time is 9.78 m/s.

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.
