Answer:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

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
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.
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.
Your science teacher gives you three liquids to pour into a jar. After pouring all of them into the jar, the liquids layer as seen in the image. What property of matter prevents the three liquids from mixing together? answers: density texture color mass
Answer:
Density
Explanation:
Each of the three liquids have different densities. Have you ever tried to mix oil and water? They don't mix because they have different densities.

im sorry this question is weird the school has some weird ones lol 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.

Z.M. says: I am building a small engine with link motion New shoots come up, but they in turn are killed off long before maturity. and no the golf ball is not denser even tho it sinks
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
What is science? APEX
A. Attempting to solve ethical problems through research.
B. Learning about the physical world through observation.
C. Using rules and patterns to predict what will do.
D. Determining a body of knowledge that never changes.
Science is Learning about the physical world through observation, therefore the correct answer for the given problem statement is option B
What is science?Science is the methodical, empirically-based pursuit and application of knowledge and understanding of the natural and social worlds.
A method of learning about the world is science. Science allows people to participate in the creation of new knowledge as well as use that knowledge to further their goals. It is both a process, a product, and an institution.
It helps us live longer and in better health, keeps track of our well-being, offers medication to treat illnesses, eases pain, helps us get water for basic requirements like food, gives us energy, and makes life more enjoyable with things like sports, music, and the newest things.
Thus, Science is Learning about the physical world through observation, therefore the correct answer for the given problem statement is option B
