Which equation represents a fusion reaction?

Answers

Answer:

B

Explanation:

I took the test

The equation that represents a fusion reaction is ²₁H + ²₁H = ⁴₂He and the correct option D.

A fusion reaction is a type of nuclear reaction that involves the merging or combining of two or more atomic nuclei to form a heavier nucleus. This process releases a significant amount of energy.

In fusion reactions, the atomic nuclei overcome the electrostatic repulsion between positively charged protons and come close enough for the strong nuclear force to bind them together. This typically occurs at extremely high temperatures and pressures, such as those found in the core of stars or in experimental fusion reactors.

The most well-known fusion reaction is the fusion of hydrogen isotopes, deuterium and tritium, to form helium. This reaction is the primary process that powers the Sun and other stars, and it is also the focus of research efforts to achieve controlled nuclear fusion for practical energy production on Earth.

Thus, the ideal selection is option D.

When you touch the screen of a smartphone, these receptors are sending messages to the brain.
pain receptors
thermoreceptors
proprioreceptors
mechanoreceptors



EXPLAIN

Answers

The mechanoreceptors are for touch, thermoreceptors detect changes in temperature, pain receptors detect pain, this only leaves proprioreceptors, therefore, this is your answer

Answer:

Mechanoreceptors

Explanation:

If Propriorceptors are for sensing light, thermoreceptors are for decenting temperatures, and pain receptors are for detecting injury, then mechanoreceptors would be used for sensing touch, and in this case you are touching the iphone screen, so mechanoreceptors is the correct answer.

~Read the article excerpt then respond to the question below.~
"Scientists make synthetic substances by arranging atoms and molecules in the lab. They use what they know about different types of atoms and molecules to arrange them and make the kinds of substances they want.
Synthetic medicines aren’t any different at the atomic level from the natural medicines found in the rainforest. After all, molecules are just molecules—whether they’re made in nature or in a lab, the same types of atoms arranged in the same ways always form the same molecules that behave in the same ways."

At the atomic level, are synthetic medicines different from natural medicines?
Explain your thinking.

Answers

Although herbal medicines are less potent in comparison to synthetic drugs in some cases but still these are consider less toxic or having less side effect in contrast to synthetic drugs. The ultimate norm for any medicine (human made or natural) is their non-toxicity, effectiveness, specificity, stability and potency.

As the mass of an object increases, what happens to the gravitational force created by that object?

Answers

Answer:

the gravitational force is proportional to the mass of both interacting objects, bigger objects will attract each other with a greater gravitational force. So the mass of either object increases, the force of gravitational attraction between them also increases.

Answer:

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force.So the gravitational attraction between them also increases.
