Answer:

25000W

Explanation:

Kinetic Energy, EK=(1/2)mv2. Energy is conserved, so the work done by the brakes, W, must be equal to the change in kinetic energy of the car, ∆EK. Therefore: W = ∆EK = (1/2)1000(152-52) = 0.51000200 = 100000 = 1*105J. Since power P = W/T, the average power output of the brakes is equal to the total work done by the brakes over the time that the brakes are applied for, therefore: P = 100000/4 = 25000W.

Which example is a body fossil? a) dino bones b) shrimp burrow c)dino footprint d)an ornithopod track
Harrizon [31]

Answer:

The hard structure like dino bones, teeth and shells are the examples of body fossils.

Option: A

<u>Explanation: </u>

The body fossils are common type of fossils found in the world. <em>These body fossils are formed by the remains of the ‘dead animals and plants’.</em> The body fossils are <em>hard parts of the dino teeth, bones, shells, woody trunks, branches, and stems.</em> The body fossils are formed in different ways and they are the remains of <em>the body parts of ancient animals, plants and other life forms.</em>

<em>They are rarely found in connected nature and are like large vertebrates like dinosaur bones, skulls and teeth’s. </em> The body fossils are also formed in different ways they are formed like a plants or animals dies in a watery environment and they can be buried in mud or silt they cannot decompose.

They build the top and hardens into the rocks at over time sedimentation.  Two types of tissues are decomposed, they are soft and hard tissues.in the decomposition of there leaving hard bones, shells and teeth’s are behind and soft tissues are quickly decomposes.

Hitman42 [59]

The question is incomplete, the complete question is;

Shah did not trust the results of an experiment that she had read about, so she is conducting the experiment herself. She goes through the same set of steps and measures the effect of the amount of sugar on a single organism.

Which best describes what Shah is doing?

replication

repetition

both repetition and replication

neither repetition nor replication

Answer:

replication

Explanation:

Replication in scientific experiments refer to the process of going through all the steps in an experiment in order to obtain the same set of results initially obtained.

All scientific experiments is expected to be replicated under identical experimental conditions. If the results obtained by a scientific investigation cannot be replicated under identical circumstances by other scientists, then the scientific data must be taken with a pinch of salt.

Shah is expected to obtain almost exactly the same data as the original researchers who first published the data.

A ringing bell sends sound waves in all<br> directions<br> places<br> sides
Strike441 [17]

Answer:

direction

Explanation:

because particles surround the bell, so when the bell vibrates, it causes particles surrounding it to vibrate back and forth vigorously. as these particles vibrate they collide with the neighbouring particles, passing on the energy.

hope this is what you are asking, if not please report it so that someone else gets to try it.
