Does the type of surface (grass, carpet, asphalt, linoleum) affect the distance a toy car can travel

Hello!

Yes it does, based on the texture of the surface

grass and carpet (big, rough texture)- it will move slower, which will cause the car to move a shorter distance

asphalt and linoleum- this will cause the car to move faster, which will lead the car a longer distance

Hope this helps a little!!!

step-by-step explanation:

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.
