Set the voltage drop across the light bulbs to approximately 4 V by adjusting the knob of the power supply and the rheostat. Measure the voltage drop across and the current through the light bulb. Repeat the measurement for the other two light bulbs. Make a note on the brightness of each light bulb.

Global warming was a major concern some people do not care global warming is fake it is not real the percentage of it happening  is slight 

This is the answer of your question

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.

C. the electric current passes from the slip rings, through the brushes, and to the collection device.
