what will happen if phase changes didn't exist?​

Answers

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.

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

Answers

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]

________ is the passing of traits from generation to generation while _________ is the scientific study of traits being passed from generation to generation.

Answers

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.

Explain how Photosynthesis and Cellular Respiration are important in your everyday life. Be Scientific! 5-6 sentences!

Answers

Answer:

Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathway through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.

Photosynthesis is a very important process in plants. It helps in the formation of glucose in plants. Cellular respiration takes place in human beings.

What is energy?

Energy is the ability to do work. All living organisms require energy to do work. Energy is transformed to chemical energy in plant cells through a process called photosynthesis.

Plants utilise the chemical energy stored during photosynthesis in their cellular respiration for essential life functions. Energy is changed during both photosynthesis and cellular respiration.

The light-dependent and light-independent processes of photosynthesis are also important for plant management.

Therefore, Photosynthesis is a very important process in plants. It helps in the formation of glucose in plants. Cellular respiration takes place in human beings.
