In figure (10), an experiment is set up to find out which metal is the best conductor of heat. Balls are stuck with wax to rods made from different metals as shown in diagram X. The rods are heated at one end. Some of the balls fall off, leaving some as shown in diagram Y. Which labeled metal would be the best conductor of heat – A, B, C, or D?
PLS GIVE ANSWER QUICK I LL MARK YOU AS BRAINLIEST

Answers

The answer is A as rod A has the least amount of wax which means that it melted the most equaling more heat

Metal A would be the best conductor of heat as the most number of balls fell from the vibration of particles.

Often referred to as a "heat conductor," a conductor of heat is a substance or material that makes it simple for heat to pass through it. Heat energy is transported from the higher-temperature region to the lower-temperature region when there is a temperature differential between two points in a conductor.

The passage of thermal energy from one molecule to another within the conductor is what causes this heat transfer process to happen. The best conductor is Metal A. The most heat, or the energy of the vibration of particles, will be conducted by the best conductor. As the greatest number of balls dropped as a result of particle vibration, metal A transmitted heat the best.

is a little weird srry A large rock is much heavier than a small water balloon. Yet, you observe that they fall at a similar rate. Why is this? The larger size of the large rock slows it down to the small water balloon speed. Water balloons change shape so that they can fall faster. The force pulling the large rock down is greater, but it takes more force to move it. The golf ball may be smaller, but it is denser.

Answers

Answer:

The force pulling the large rock down is greater, but it takes more force to move it.

Explanation:

There's a greater force on the large rock, but it's harder to move because of its large mass.  The force on the golf ball is smaller, but it has less mass, so it doesn't take as much force to move it.

So a large force on a large mass will have the same acceleration as a small force on a proportionately small mass.

Explanation:

Any two objects that have mass attract each other with a force we call gravity.  You probably never noticed this for small objects, because the force is so weak.  But the Earth has lots of mass, and so it exerts a big gravitational force on you.  We call that force your weight.  The fact that gravity is actually a force of attraction is not obvious.  Prior to the work of Isaac Newton, it was assumed that gravity was simply the natural tendency of objects to move downward. this is why they

There’s a time with gravity where no matter what the objects move at the same force. There’s a point where it reaches its max speed and cannot go faster.
