Abaseball, hit 7 feet above the ground, leaves the bat at an angle of 75 and its caught by an outfielder 7 feet above the ground and 300 feet from home plate. how high does the ball rise? round your answer to the nearest integer.

139 ft/s

Explanation:

Given

ball leaves the bat at angle of

as the height with ball is launched and height of fielder is same so its vertical displacement is zero and ball is considered to complete a projectile motion with range =300 ft

Also range of projectile is given by

where u= launch velocity

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.
