Along solenoid with 1.00 3 103 turns per meter and radius 2.00 cm carries an oscillating current i 5 5.00 sin 100pt, where i is in amperes and t is in seconds. (a) what is the electric field induced at a radius r 5 1.00 cm from the axis of the solenoid? (b) what is the direction of this electric field when the current is increasing counterclockwise in the solenoid?

Efficiency is an action of doing something. for example when you take a test. good efficiency means you did well but bad effeciency or no effiency means you did bad.

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
