Also 4 sec. Without air resistance, all objects fall with the same acceleration, and reach bottom in the same amount of time.

That completely depends on the size of the orbit. Similarly at Earth, a TV satellite takes 1 day for an orbit, but the Moon takes 27.3 days.

I'm not really good on this type of stuff :(
navik [9.2K]
Okay let me walk you through this, a resistor resists right? its in the name. so you can guess that it would be 4th one down, because if you resist you don't stop, you just slow down. So you should definitely know current is energy, and since electrons is energy you know that current is the second one down. You already have two. Heres a good test taking strategy, the first one says "materials that do conduct electricity just not as well as conductors" so you know that something that conducts electricity well is a conductor, the third one down. now you have 3/5 and you haven't used any real knowledge. So now you are stuck between something that blocks electricity and something that is okay with it. Since you know a conductor does good, wouldnt a semi-conductor be the first one? since it is semi or partially a conductor. Then you are left with insulators to block them out. I hope I left a decent enough explanation. :)

A horseshoe magnet is held vertically with the north pole on the left and south pole on the right. A wire passing between the po
sergejj [24]

Answer:

Force acts vertically downward

Explanation:

Solution:-

The force is downward. The field lines point from the north pole to the south pole, or left to right. We will apply the use of right-hand rule. Your fingers point in the direction of the current (away from you). Curl them in the direction of the field (to the right). Your thumb points in the direction of the force(downward).

How does the resistance change as you add bulbs to a series circuit? The resistance does not change. The resistance decreases. T
Anon25 [30]
Light bulbs are loads, so they have a certain amount of resistance associated with them. In series, Resistance total = R1 +R2 +R3...
So the more resistance you add, the more resistance there is! Therefore, the resistance increases!
