The velocity of 16 m s-1 at an angle 0 to the horizontal. When the ball reaches its maximum height, its kinetic energy is 16 J.
A. What is the maximum height achieved by the ball from its point of release?
B. Calculate the initial vertical velocity of the ball.
C. What is the value of 0?
D. What is the speed of the ball after 1.0 s?
E. What is the displacement of the ball after 1.0s?
F. How long after the ball is thrown will it return to the ground?
G Calculate the horizontal distance that the ball will travel during its flight.

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:

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
