Camels can run faster than horses in desert give reason.​

Explanation:

Camels have wider hoofs, the reduced pressure of their feet makes the camel run faster in the desert. Their eyes are used to blowing sand so it does not affect their speed.

As they have a wider hoofs their foot dont sink in sand so they can easily run or walk.

because camels have wider hoofs and reduced pressure of their feets

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:

it has to be b, about 97 percent.
