PLEASE HELP! Will give brainliest Q: How do you determine speed over a crooked path? Explain!

Tysm!

Explanation:

You cant if the path is crooked then speed wont help but throw you off the track over and over.

Depends.

Explanation:

It may be a bit harder because of the path's winding direction, but like the other question I answered, direction does not matter when calculating speed. So, you should be able to determine the speed using the formula per normal.

That is, if this path has railing of some form.

If not, then this answer is almost impossible.

No. Quite literally, it will be impossible, if not very difficult, to calculate an accurate speed.

(speed = distance ÷ time)

Hope this helped!

Source(s) used: My mind and a little bit of G*ogle as a refresher.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

the total distance traveled by the car is

30km + 49km = 79 km .
