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

what should you do if you are not sure that an organism is a plant
Answer:
An organism refers to a living thing that has an organized structure, can react to stimuli, reproduce, grow, adapt, and maintain homeostasis.
Explanation:
An organism is a plant.
If you are not sure that an organism is a plant, you should observe and research the characteristics and behaviors of the organism to determine its classification.
What is the five kingdom classification?The five kingdom classification is a system of classifying living organisms into five major categories based on their fundamental characteristics. The five kingdoms are:
Monera: This kingdom includes single-celled prokaryotic organisms, such as bacteria.Protista: This kingdom includes single-celled eukaryotic organisms, such as algae and protozoa.Fungi: This kingdom includes multicellular, heterotrophic organisms, such as mushrooms and yeasts.Plantae: This kingdom includes multicellular, autotrophic organisms that are characterized by their ability to photosynthesize, such as trees, flowers, and grasses.Animalia: This kingdom includes multicellular, heterotrophic organisms that are characterized by their ability to move and sense their environment, such as animals and humans.Learn more about classification, here:

Explanation:
What is the function of the conjugation pilus?.
what will happen if phase changes didn't exist?
Answer:
Matter can exist in one of several different states, including a gas, liquid, or solid state. The amount of energy in molecules of matter determines the state of matter.
A gas is a state of matter in which atoms or molecules have enough energy to move freely. The molecules come into contact with one another only when they randomly collide.
A liquid is a state of matter in which atoms or molecules are constantly in contact but have enough energy to keep changing positions relative to one another.
A solid is a state of matter in which atoms or molecules do not have enough energy to move. They are constantly in contact and in fixed positions relative to one another.

Answer:
Explanation:
The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
________ is the passing of traits from generation to generation while _________ is the scientific study of traits being passed from generation to generation.
Answer:
Heredity,Genetics
Explanation:
Heredity is the passing of traits from generation to generation while Genetics is the scientific study of traits being passed from generation to generation.
Traits are the defining characteristics that are passed from generation to generation, and genetics is a branch of science to study heredity.
What is genetics?Genetics is the branch of science to study heredity and evolution, how genes originate and what changes occur over time.
Genes are segments of DNA upon chromosome code for protein, in the genetics gene is the major area of study. How a gene can be transferred from parents to a daughter and lead to heredity can be studied.
Heredity depends on the gene responsible for a particular trait and character, during evolution, there would be changes occur at the genetic level which leads to variation among species.
Therefore heredity is to pass traits, and the scientific study of it is genetics.
