volume of box is 30cm cube breadth is 5cm height is 2m find length

Answers

Answer:

3 cm

Explanation:

I think the question have some error because if height = 2 m = 200cm.

Volume of box = l * b * h

V = 30 cm³

b = 5 cm

h = 2 cm

l = ?

V = l * b * h

30 cm³ = l * 5 * 2

l = 30 / 10

l = 3 cm

Psychology is not considered a natural science. While it deals with the study of the human mind and behavior, psychology is generally classified as a social science rather than a natural science.

What are natural sciences?

Natural science is a branch of science that deals with the study of the natural world, including the physical, chemical, and biological aspects of nature. It is a systematic and empirical approach to understanding the natural phenomena that occur in the universe. Natural sciences include subjects such as physics, chemistry, biology, geology, and astronomy, among others.

These sciences use the scientific method to investigate and explain the behavior of the natural world, relying on observation, experimentation, and analysis of data to formulate theories and laws that can explain natural phenomena. Natural science plays a critical role in our understanding of the universe and has contributed immensely to technological advancements in various fields. Therefore, option (B) is correct.

scientist use empirical evidence, logical thinking, and tests to ___ a scientific explanation.​

Answers

Answer:

Explanation:

The only word I can think of is confirm.

I choose confirm because they have already used empirical evidence (evidence that is primarily found by the senses. We hear something, we see something, We smell something -- although this is rather rare. Probably we would hear or see something first). We've used logical thinking, and we've likely even performed experiments.

So we've done all the ground work. All of these things are needed to confirm a scientific thought or premise that has been proposed. All of them aim at confirming what  we proposed.

Can you answer this math homework? Please!

Answers

[tex]\large \mathfrak{Solution : }[/tex]

9. An object which is in circular motion (moving along a circle) is said to be accelerating because it changes it's direction constantly even if it is moving with a constant speed. cuz acceleration is change in either magnitude or direction of an object with respect to time.

therefore, it's still acceleration as change in direction with time.

10. Average speed of an object can be calculated by dividing the total distance covered by an object by time taken to cover that distance.

i.e

[tex] \boxed{speed = \dfrac{distance}{time} }[/tex]

it can be re- arranged to find the distance as :

[tex] \boxed{distance = speed \times time}[/tex]

[tex]time = \dfrac{distance}{speed} [/tex]

11. speed = 20 m/s : conversion into km/h

distance covered : 4 km = 4000 m

[tex]time = \dfrac{distance}{speed} [/tex]

[tex]t = \dfrac{4000}{20} [/tex]

[tex]t = 200 \: \: sec[/tex]

time taken = 200 seconds

12. let's use the first equation of motion to find the acceleration :

[tex]v = u + at[/tex]

[tex]50 = 80 + 120a[/tex]

[tex]50 - 80 = 120a[/tex]

[tex]a = \dfrac{ - 30}{120} [/tex]

[tex]a = - \dfrac{1}{4} m/s {}^{2} [/tex]

[tex] - 0.25 \: \: m/s {}^{2} [/tex]

if the light is both wave and particle ..
then when light is said to be wave and when it is said to be particle ?​

Answers

Answer:

Consider electrons incident on a Young's double slit

If one slit is covered, the electrons will form a maximum, on the screen, as if they were particles incident on the screen

If both slits are open, the pattern formed on the screen will be the same as if a wave were incident on the screen, even tho electrons are slowed to the point that only 1 electron is incident on the screen at one time.

That means that the electron interferes with itself to create the  interference pattern on the screen, and there is no way to determine which slit the electron went thru without destroying the interference pattern.

What value relates the speed of light in a vacuum to speed of light in a given material?

Answers

The index of refraction

Hold up let me tell you why!!!
The index of refraction which is also known as refractive index is defined as speed of light in a vacuum divided by the speed of light in a giver material.
The formula for index of refraction is:
(n = c ÷ v)
This is where n represents index of refraction
C which represents of light in a vacuum
And V represents speed of light in a given material.
So the speed and the direction of light changes when it moves from one medium to another. And the change direction is basically called refraction......
