During the annual shuffleboard competition, renee gives her puck an initial speed of 8.12 m/s. once leaving her stick, the puck slows down at a rate of -3.06 m/s2. how long did it take to stop?

Explanation:

Let be the acceleration.

Let be the initial velocity.

Let be the final velocity.

Let be the time taken.

As we know from the equations of motion,

Given,

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.

a displacement distance is size of displ
