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]

While you’re waiting for the lactase solution to cool, read the directions on the test strips. The test strips in the Edmentum lab kit will react to glucose within a few seconds. If you use different strips, the reaction time may vary. Now follow these steps to test the solutions. Record your data in the answer space.
Milk and water solution: Fill the first test tube one fourth full of milk. Fill the small graduated cylinder with water and gently add it to the milk in the test tube until the test tube is half full. Use the stirrer to thoroughly mix the solution. Then insert the test strip for 10 to 20 seconds. Look at the test strip, and record whether it changed color. Wash the stirrer.

What condition occurs when epidermal cells are created too quickly? a. Acne c. Psoriasis b. Skin cancer d. Chicken pox.
The condition that occurs when epidermal cells are created too quickly is known as psoriasis. In this disease, the cell cycle of skin cells is abnormally accelerated.
Psoriasis is a skin disease associated with itchy patches of thick, red skin, especially in the knees, trunk, and scalp.
Psoriasis is an autoimmune disease caused when the immune system attacks healthy skin cells.
Psoriasis is well characterized by hyperproliferative keratinocytes, which are the most prominent type of cell within the epidermis.

Why do parasites not require complex nervous or muscular tissue?
Porque los parásitos no requieren tejido nervioso o muscular complejo?
Answer:
Hey mate.....
Explanation:
This is ur answer.....
Poorly developed nervous and muscular systems – because parasites live inside their hosts, they don't need eyes, ears or a keen sense of smell to detect potential predators nor a brain to facilitate escape. They have little need for a muscular system because they have no place to go.

What is the role of density changes in a convection cycle
Answer:
Explantion
Convection is heat transfer due to a density differential within a fluid. As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks. ... Air from above the ocean is colder and more dens
Convection is the transfer of heat caused by a density difference within a fluid. Water becomes less dense and rises as its temperature rises in the presence of a heat source.
What is convection?Convection is a method of moving heat that is also known as a heat transfer mechanism. When a fluid, such as air or water, is in motion, heat is transferred. Temperature differences across the fluid drive convection.
Differential heating causes convection currents. Warmer (less dense) material rises, while cooler (more dense) material sinks.
This movement is responsible for the formation of circulation patterns known as convection currents in the Earth's atmosphere, water, and mantle.
Convection is the heat transfer resulting from variations in density within a fluid. In the presence of a heat source, water becomes less dense and rises in density.
Thus, this is the role of density changes in a convection cycle.

Explain how pollution from one location
can affect the environment far away from the
source of the pollution
Answer:
Air quality is affected by natural processes. Wind can move pollutants from their source to far-away locations. It can still spread and harm living creatures and destroy their environments.
Explanation:
Air quality is affected by natural processes where wind can carry pollutants to places far away from their source which can still spread and harm living beings and destroy their environments.
What is Pollution?Pollution is defined as the introduction of harmful materials into the environment where the harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash which can also be created by human activity, such as waste or runoff produced by factories. Pollutants harm the quality of air, water and land.
Many things produce pollution such as cars spewing pollutants from their exhaust pipes. Burning coal to generate electricity pollutes the air. Industries and homes generate waste and sewage that can pollute land and water. Pesticides which is chemical poisons used to kill weeds and insects which is seep into waterways and harm wildlife.
Thus, air quality is affected by natural processes where wind can carry pollutants to places far away from their source which can still spread and harm living beings and destroy their environments.

Which of the following characteristics do homologous chromosomes exhibit?.
Homologous chromosomes carry alleles of the same traits and therefore, carry the genetic information for the same trait.
Homologous chromosomes are a pair of chromosomes with the same gene sequence but of different origins - one paternal and the other maternal.
Thus, homologous chromosomes carry the same traits, although could be of different forms. For example, one of the chromosomes might carry a gene for tallness while the other might carry a gene for shortness even though both tallness/shortness represent a gene for height.
