... power p supplied to a resistor whose resistance is r when it is known that it has a voltage δv across ... supplied to a resistor whose resistance
i squared r = 0.03x0.03x1000=3x0.03x10=.9W
Air resistance, also called drag, acts upon a falling body by slowing the body down to thr point where it stops accelerating, and it falls at a constant speed, known as the terminal volocity of a falling object. Air resistance depends on the cross sectional area of the object, which is why the effect of air resistance on a large flat surfaced object is much greater than on a small, streamlined object.
52m/s is the answer because before it was gonna accelerate it was 52 m/s
Postitive ions have more protons than electrons, because protons are positively charged. Electrons have a negative charge, so if there were less protons than electrons the job would be negative. If there were the same amount of both, then the positive and negative charges balance each other out, making a neutral charge.
