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]

Crime-scene work often involves obtaining a DNA sample from a drop of blood to help identify persons who may have been involved. Frequently, the size of the DNA sample is extremely small, too small for easy analysis. Which of the following laboratory procedures could criminologists use to amplify the amount of DNA present?

A: Cloning and gel electrophoresis
B: Cloning and polymerase chain reaction (PCR)
C: DNA splicing and polymerase chain reaction (PCR)
D: Vector amplification and DNA splicing

Answers

Amplification of DNA is a very useful tool in the study of the human genome. DNA amplification ensures the production of multiple copies of the needed segment.

Criminologists can use Cloning and PCR to amplify the amount of DNA present...

Cloning involves creating identical copies of a particular DNA segment in study. Then amplification of the DNA using polymerase chain reaction will aid in amplifying and producing thousands of these copies of short targeted segments in minutes. This tool is very useful in ensuring the multiplication of that particular targeted sequence for analysis.

Answers

Answer: At low latitudes, near the equator, direct overhead sunlight received all year warms surface waters.

Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.

Explanation:

Answer:

The density of ocean water is so varied, that while there may be a generally considered variation due to temperature, taking random samples in a wide variety of places, thus you can distinguish no real pattern.

Which hormone is responsible for the development of the male secondary sex characteristics? estrogen progestin progesterone testosterone.

Answers

Answer:

It is Testosterone

Explanation:

The hormone responsible for the development of the male secondary sex characteristics is testosterone. Hence option D is correct.

What is testosterone?

Testosterone is a hormone primarily produced in the testes of males and to a lesser extent in the ovaries of females and the adrenal glands of both sexes. It is an androgen, or a hormone that promotes the development of male characteristics.

Testosterone plays a crucial role in the development of male reproductive tissues, such as the testes and prostate, as well as in the growth of muscle mass and bone density.

It is also responsible for the development of secondary sex characteristics in males, such as facial hair growth, a deepening of the voice, and the growth of Adam's apple. Testosterone also regulates sex drive (libido) and sperm production.

In females, testosterone is produced in smaller amounts and helps regulate the menstrual cycle and promote bone density.

An imbalance of testosterone levels in either males or females can lead to various health issues, including infertility, osteoporosis, and disorders of sexual development.

Hence option D testosterone is correct.

The Mojave Desert is a desert that comprises parts of southern California and small parts of Northern California, southwestern Utah, southern Nevada, and northwestern Arizona, in the United States.

A desert is a biome which receives very little annual precipitation. As a result of this it exhibit very hot and dry climatic conditions. The soil generally losses it's fertility which may either become compact or remain in loose form due to erosion like sand. The plants exhibit fleshy leaves so as to prevent the loss of water through transpiration.
