What is the most important reason to control the condition of a experiment

Answers

Answer 1
Answer: The most important reason to control the conditions of an experiment is to make sure that the environment is affecting the results of the experiment--which would void the study.

How is the frequency of an electromagnetic wave related to energy?A) As the frequency of the wave decreases, its energy increases.
B) As the frequency of the wave fluctuates, its energy decreases.
C) As the frequency of the wave increases, its energy also increases.
D) As the frequency of the wave changes, its energy remains constant.

Answers

As the frequency of the wave increases, its energy also increases. The correct option is C.

The frequency of an electromagnetic wave is defined as the number of oscillations or cycles per unit of time.

The frequency of the wave, on the other hand, is directly proportional to energy.

The energy of an electromagneticwave is precisely proportional to its frequency, according to the equation E = hf, where E represents energy, h is Planck's constant, and f is the frequency of the wave.

Simply said, higher frequency waves have more energy than lower frequency waves.

This is true over the whole electromagneticspectrum, from radio waves to gamma rays. The energy carried by the wave rises as the frequency of the wave increases.

Thus, the correct option is C.

What are the divisions within a shell called

Answers

The divisions within an atom's shell are called subshells. This means that each shell consists of several subshells that are made up of orbitals. Each orbital consists of 1 or 2 electrons. The outermost shell of an atom is what we call the valence electrons, and they are what participate in chemical bonding.

The Sun and most stars are made almost entirely of a. hydrogen and carbon. b. helium and nitrogen. c. oxygen and nitrogen. d. helium and hydrogen.

Answers

So the question is what are the Sun and most stars almost entirely made of. So most stars, including our Sun are made out of hydrogen and helium. There is also a small percentage of oxygen, carbon and nitrogen and also very small quantities of iron, silicone and other metals. So the correct answer is d.

There are some cases where distance time graph of a particle is vertical . So could you please tell me when it is possible????

Answers

-- If time is the horizontal axis and distance is the vertical axis, then it's not possible
for the particle's distance/time graph to be a vertical line.  That would indicate that
the particle covered some distance in zero time, indicating infinite speed.

-- If distance is the horizontal axis and time is the vertical axis, and the particle's
distance/time graph is a vertical line, then that indicates that the particle's distance
doesn't change with time. In other words, the particle is at rest, and its speed is zero.
when the body is in rest or in constant speed

A wave x meters long has a speed of y meters per second. The frequency of the wave isa. x/y hertz
c. y x hertz
b. y/x hertz
d. y x hertz

Answers

The correct answer is (b.) y/x hertz. That is because the formula to get the frequency is f =  v / w. The following values (v=y meters / second; wavelength = x meters) must be substituted to the equation, which leaves you y/x hertz.

Answer:

b. y/x hertz
