Calculate the kinetic energy of a
30 g bullet fired at 200 m/s.

Answers

Answer 1

Step 1: Identify the formula needed to solve this problem.

The formula for kinetic energy (KE) is:

KE = 1/2m~v^2

m = mass

v = velocity

Step 2: Make a list of the values given in the question.

mass (m) = 30 g

velocity (v) = 200 m/s

[tex] \frac{1}{2} m {v}^{2} \\ \frac{1}{2} \times 30 \times {200}^{2} \\ 15 \times 40000 \\ = 600000[/tex]

Answer 2

Answer:

6 × 10⁵ J

Explanation:

Kinetic Energy of a moving mass is defined as, half of the product of it's mass and the square of it's velocity.

[tex] \boxed{ \mathsf{K.E. = \frac{1}{2} m( {v})^{2} }}[/tex]

Mass of the bullet (m) = 30 gvelocity (v) = 200 m/ s

[tex] \implies\mathsf{K.E. = \frac{1}{2} \times 30 \times ( {200})^{2} }[/tex]

[tex] \implies\mathsf{K.E. = 15 \times 4 \times {10}^{4} }[/tex]

[tex] \implies\mathsf{K.E. = 60 \times {10}^{4} }[/tex]

[tex] \implies \underline{\mathsf{K.E. = 6 \times {10}^{5} J }}[/tex]

In order to detect an odor, molecules must first dissolve in the ____________ before they bind to the receptor sites of the ____________ .

Answers

For an individual to detect an odor then molecules must first dissolve in the

mucus before they bind to the receptor sites of the olfactory hairs.

The nose is the organ responsible for smelling and it possesses key

components such as the mucus found in the olfactory epithelium and

receptors found in the olfactory hairs for processing the type of smell to the

brain.

When individuals inhale substances, they are dissolved in the mucus to aid

their binding to the receptors and their subsequent relay of the signal to the

brain for processing.

How is real life fingerprinting different from the techniques used on CSI?

Answers

CSI used various techniques for fingerprinting like powder dusting, iodine fuming, silver nitrate soaking, etc to determine the fingerprint of criminals.

What do you mean by CSI?

CSI stands for Crime Scene Investigation. It is a brach that investigates crime scene evidence.

Real-life fingerprinting does not involve critical techniques for identification. While CSI performs various techniques and is able to find the most similarity between the real criminal involves in any violent activity.

Therefore, CSI used various techniques for fingerprinting like powder dusting, iodine fuming, silver nitrate soaking, etc to determine the fingerprint of criminals.

https://brainly.com/question/25961570

Real-life fingerprinting differs from CSI techniques. While CSI portrays fingerprint analysis as rapid and foolproof, reality involves a slower and more nuanced process.

Real-life fingerprinting is a more involved process than the quick and ostensibly error-proof fingerprint analysis seen on CSI. CSI frequently depicts fingerprint matching as a straightforward database search that produces instant identification. However, in the actual world, fingerprint analysis is carried out by skilled experts who painstakingly check ridge patterns, minute spots, and other traits to assure precise matches. To avoid mistakes, this procedure can be time-consuming and requires knowledge.

In addition, the way that huge, networked databases are shown in CSI oversimplifies reality. Although modern technology makes fingerprint comparison easier, the vast network of records that are easily available is more fantasy than reality. Real-world law enforcement databases are subject to stringent guidelines and restrictions.

B) the protons in each atoms.

C) all electrons in the atoms.

D) the valence electrons in each atom​

Answers

Answer:

C - All electrons in the atoms

Explanation:

It depends on the bonding for an explanation.

If one atom is a metal and one is a non metal it will be ionic. This is because one atom transfers its electron to the other atom giving them both a charge. They will then be bonded due to opposite forces of attraction.

If both atoms are non metals it will be covalent. Electrons pair together in the center of two atoms that have merged together and they share their electrons.

The invasive or introduced species in the United States has seen an economic impact since the damage can be seen in both animals and plants. Now with an invasive species brought about, the naturally occurring species are left fighting for a spot in the habitat and lose in most cases. So economically, the United States has to spend money to get rid of the invasive species

Some of the invasive species have been known to live all year long, and so during the winter seasons, they act as food sources to birds and other animals.

what determines how closely related 2 species are?

Answers

Answer:

Before: (Darwin did) Physical features and behavior

Now:

DNA Testing

Explanation:

Similarities are often easy to see when one looks at two organisms that evolved from a common ancestor, and until recently, looking at physical features and behavior was the only way to determine how closely related two organisms are. However, now scientists can also analyze DNA to discover how closely organisms are related. Every living creature has DNA, which has a lot of inherited information about how the body builds itself. Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms. This method can also help when looks are deceptive. One example of looks being deceptive is: The bat and the crow both have wings, and the squirrel does not. From this, one may think that bats and crows are more closely related than bats and squirrels, while the opposite is indeed the case.
