Answer:

In a mixture, each substance is still the same and don't really combine. In a compound, the substances are chemically combined (so the substances that went in have technically changed).

Explanation:

A compound contains atoms of different elements chemically combined together in a fixed ratio. While on the other hand, a mixture is a combination of two or more substances where there is no chemical combination or reaction.

Owls, hawks, and eagles are types of raptors, animals which have hooked beaks and sharp claws, and are therefore adapted for seizing prey animals. Hawks and eagles differ from owls in that they eat their prey animals by tearing them into small pieces, picking out the flesh, and avoiding most of the fur and bones. They also have strong stomachs that can digest most of the bone material which they might eat. The relatively small amount of indigestible bone and fur that remain will be compacted by their stomach muscles into a pellet similar to the owls. Do you think an eagle pellet would be as useful for dissecting as an owl's? Why or why not? Explain your reasoning.

Answers

I do not think that the eagles pellet would be as useful for dissecting as an owls

An eagle pellet wouldn't be as useful for dissection as an owl pellet. The pellet also contains the animal's bones and fur.

What is dissection?

Dissection is the dissection of an animal or plant's body to examine the anatomical structure. In pathology along with forensic medicine, autopsy is used to identify the cause of human death. In biology or natural science classrooms under middle school as well as high school, less thorough dissections of plants or smaller animals stored with a formaldehyde solution are often carried out or displayed.

Medical students on medical schools perform in-depth dissections on adult and child cadavers, both fresh and preserved, as part of their instruction in topics including anatomy, pathology, and forensic medicine. As a result, dissection is frequently performed at an anatomy lab or a mortuary. An eagle pellet wouldn't be as useful for dissection as an owl pellet. The pellet also contains the animal's bones and fur.

Therefore, an eagle pellet wouldn't be as useful for dissection as an owl pellet. The pellet also contains the animal's bones and fur.

The average speed of the blocks are 0.36 m/s.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed with respect to time. As at time t = 0 , the speed is also zero, and at time t = 2.5 s , the speed will be
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
The answer is 0.36 m/s credit to the guy above me (give him Brainlyist) but I also had to do this assessment.

Newton's second law of motion is F = ma.

A net force of 60 N north acts on an object with a mass of 30 kg. Use Newton's second law of motion to calculate the amount of acceleration the object will experience. Then explain how the amount of acceleration will change if the net force or the mass of the object increases.

Answers

Answer:

this was asked before here the screenshot

If F=ma then A= f/m so 60 divide 30 = 2
If force increases then acceleration will increase too example 90/30=3
But if mass increases acceleration decreases example 60/60 =1
