Harold the hurler is a physics student who is renowned for his baseball pitching arm. in order to determine the amount of work he performs in throwing a baseball, harold devises an experiment. he stands at the bottom of a deep pit and hurls a 146-g baseball through an open third-floor window in a nearby building. harold\'s aim is so accurate that the ball then smoothly enters the tube of the baseball absorber that harold invented and patented. in this device the ball compresses a spring until it comes momentarily to rest, and this maximum amount of compression is recorded as 43.1 cm. the spring\'s force constant is 817 n/m, and the position of the baseball\'s momentary rest is 7.71 m above ground level. the point in the pit where the hurler starts his pitch is 11.3 m below ground level. how much work does harold perform on the baseball? take g = 9.80 m/s2.answer in j

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.
