Determine a mathematical expression for the source. Meaning use the unit step function u(t) in your expression. 3.2: At t =0- (just before the voltage changes), for the polarities indicated, determine the voltage across each component and the current through each component. 3.3: At t=0+ (just after the voltage changes), determine the voltage across each component and the current through each component for the polarities indicated in the circuit.

Where are the options ?

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.

The correct answer is antinodes

The law of conservation of momentum will be the same no matter where you apply it.the equation will be  77.4 + m (mass of canister) *3.6
