the answer is 4.

explanation:

A student lists some possible ways to investigate the transfer of kinetic energy using ice in a sample of water. The procedure would be best to investigate the transfer of kinetic energy is Determine temperature and mass of water. Put ice in water. Record the time for ice to melt. Therefore, option 4 is correct.

What do you mean by kinetic energy ?

The term kinetic energy is define as the energy of motion, observable as the movement of an object. The formula of kinetic energy is as follows:

Kinetic energy = 1/2 mv²

Kinetic energy exists in every moving object and particle. Kinetic energy is demonstrated by a person walking, a soaring baseball, a crumb falling from a table, and a charged particle in an electric field.

Kinetic energy is the energy held by a moving object. Kinetic energy exists in the earth's rotation around the sun, you walking down the street, and molecules moving in space.

Thus, option 4 is correct.

Can someone tell me the answer to this?

Explanation:

Answer:

Explanation:

Help please! i dont understand

1. Mass no.= protons+ neutrons,
Therefore, mass no. of sodium = 11 + 12 = 23

2. Total no. of electrons in a neutral sodium atom (has not reacted with anything, thus has not lost any electrons, thus is neutral) = Atomic no. = electron no. = 11

3. So as mass no. of magnesium is 24, and mass no. = protons+neutrons, and no. of protons is 12, then no. of neutrons= atomic no. - protons = 24-12= 12

4. Atomic no. = no. Of electrons= 13

5. Mass no. = protons+neutrons= 31
No. Of neutrons=16
Therefore, no. Of protons= Mass no. - neutrons= 31-16=15
Also- no. Of protons=no. Of electrons= 15 (another way to solve)

The equation shows a chemical reaction using 64 grams of calcium, 162 grams of zinc carbonate, and 152 grams of calcium carbonate.

calcium + zinc carbonate → calcium carbonate + zinc

According to the law of conservation of matter, how much zinc is present in the product?
Group of answer choices

74 grams

98 grams

88 grams

64 grams

Answers

98 grams I think so

It’s 74 grams
162-152=10
64+10=74
So 74 grams is the answer

What is true about the force acting on the cars at the end of a roller coaster ride as they slow down right before stopping?

Answers

That the gravity dosent Change

The cars will slow down as a result of unbalanced forces and negative acceleration.

What is Inertia?

Inertia is the ability of an object to continue its current motion until and unless some external force causes its speed or direction to change. Inertia is described in the Newton's first law of Motion.

The cars are slowed due to negative acceleration of the object eventually to a stop, because of these unbalanced forces due to friction which are acting on them. The riders, which have inertia, are also acted on by the unbalanced forces throughout the ride causing them to change their state of motion.

Answer:

Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.

Explanation:

Interesting fact...

Why are there differences between the cooling rates of sand and water? Sand cools off faster than water because sand is a solid. Water heats up slower and cools off slower than sand. Sand heats up faster and cools off faster than water.

As a variable and to count as land. As if you were at a beach, this sand would count as the sand that the sun would be beaming on. ^^

What is the relationship between the French in Louisiana and the native people? The zika virus was first identified in Uganda in 1947. The virus is transmitted from person to person by a bite from a mosquito. It is commonly carried by the Aedes mosquito which is prevalent throughout Central Africa. The virus has more recently spread to the Americas (South, Central, and now North) and is expected to spread to Europe. There is a concern that the virus may reach epidemic proportions. Zika virus is related to yellow and dengue fever. Common symptoms are low grade fever and a distinctive skin rash and other symptoms include vomiting, headache, and muscle and/or joint pain. Pregnant women should avoid traveling to areas known to have zika virus present because the virus is known to cause microcephaly and developmental difficulties related to the central nervous system. Based on the paragraph above, class discussions, and other VALID (be careful with your selection of e-materials! CDC Center for Disease Control is a good place to start) sources of information please answer the following questions. 1. State a reason why the virus has spread to the Americas and likely to spread to Europe. 2. Define the term microcephaly.3. What bones of the fetal skull would be affected by zika?

Eduardo has been reading about the use of drone technology in recent military conflicts and is not quite sure what to think. On the one hand, the use of drones means that military missions can be executed without putting American lives at risk. On the other hand, this very fact means that our political leaders might be quicker to resort to military solutions when other solutions might be available. Eduardo is also concerned about other effects of fully mechanized battle operations. For instance, unlike a human soldier, a drone can neither hear nor sympathize with a mother pleading for the life of her innocent child. Eduardo has decided to research the topic of military drones in more detail and write an essay in which he decides whether the use of drone technology is a positive or negative development in the history of American military action. Which type of argument will Eduardo be making? a. Argument of factb. Argument of definitionc. Argument of evaluationd.
