Child slide down a hill with an acceleration of 2.9 m/s^2 if she start with an initial velocity of 2.3 how far does she travel in 5.0 second

 Distance traveled in 5 seconds = 47.75 meter.

Explanation:

 We have equation of motion , , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.

 In this the velocity of body = 2.3 m/s, acceleration = 2.9 , we need to calculate displacement when t = 5 seconds.

So, distance traveled in 5 seconds = 47.75 meter.

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 answer is a 3.8cm
