A dog sled was moving to the right on an icy surface with low friction, when the connecting rope between the sled and the dogs broke. What happens to the motion of the sled? *

The sled will slow down in speed

Explanation:

According to Newton's first law of motion, a body will continue to be at rest or uniform motion unless acted upon by an external force.

In this situation, once the connecting rope between the sled and the dogs breaks, the motion of the sled will reduce because it is no longer connected to the dog that is providing the motion, hence the source of motion is no longer connected to the sled

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 components of a vector are the parts of the vectors that are to each other.
