Answer:
a) m_ttoal = 40x, b) m_total = 100X, c) m_total = 400X,
d) m_total = 1000 X
Explanation:
La magnificación o aumentos es el incremento de del tamaño de la imagen con respecto al tamaño original del objeto, en la mayoria del os sistema optico la magnificacion total es el producoto de la magnificación del objetivo por la magnificación del ocular
m_total = m_ objetivo * m=ocular
apliquemos esto a nuestro caso
1) m_total = 4 x * 10 x
m_ttoal = 40x
2) m_total = 10X * 10X
m_total = 100X
3)mtotal = 40X * 10X
m_total = 400X
4) m _totla = 100x * 10 X
m_total = 1000 X
en este ultimo caso para magnificación grandes es decalcificar el objeto
The total magnification produced by different combinations of eyepiece and objective lenses in a microscope.
1. When the scanning (4X) objective is used, the total magnification will be 40X because the eyepiece magnification is 10X and the objective magnification is 4X.
2. When the low power (10X) objective is used, the total magnification will be 100X because the eyepiece magnification is 10X and the objective magnification is 10X.
3. When the high power (40X) objective is used, the total magnification will be 400X because the eyepiece magnification is 10X and the objective magnification is 40X.
4. When the oil immersion (100X) objective is used, the total magnification will be 1000X because the eyepiece magnification is 10X and the objective magnification is 100X.

Answer:
The radius is
Explanation:
From the question we are told that
The current is
The magnetic field is
Generally the magnetic field produced by a current carrying conductor is mathematically represented as
=>
Here is the permeability of free space with value
=>
=>
Given that,
Power = 60 W
Distance = 1.0 m
Distance between speakers = 1.5 m
We need to calculate the intensity
Using formula of intensity
Put the value into the formula
We need to calculate the intensity
Using formula of intensity
Put the value into the formula
We need to calculate the intensity of the sound waves produced by four speakers
Using formula for intensity
Put the value into the formula
Hence, The intensity of the sound waves produced by four speakers is 13.78 W/m².
The definition of waves that propagate through electric fields is called electromagnetic waves. The earth, despite being covered with clouds, can be 'affected' because waves such as sunlight or the moon have the ability to penetrate and be visible to the inhabitants of the earth. Microwaves and radio waves would be less affected by the clouds that cover the Earth.
Through these waves, you can know that there is beyond the clouds.
Ultraviolet light, microwaves and radio waves are the radiations that penetrate through the clouds and reach the Earth's surface.
Therefore, the answer is Yes, ultraviolet light, microwaves and radio waves are the forms of radiation that penetrate and reach the ground.
It is indeed possible to learn about the universe beyond the clouds due to other non-visual forms of radiation, mainly radio waves and gamma rays, which can penetrate through the clouds and reach the earth's surface.
Yes, even if Earth were completely blanketed with clouds and we could not see the sky, we could still learn about the universe beyond the clouds. This is because, in addition to visible light which would be blocked by the clouds, the universe also emits various other forms of radiation that can penetrate the clouds and reach the ground.
Two major types of radiation that could penetrate the dense clouds are radio waves and gamma rays. Radio waves are a form of electromagnetic radiation used in many areas of science and technology, while gamma rays are highly energetic forms of radiation and are used in fields such as astronomy to get valuable information about distant celestial bodies.

Answer:
The force constant of the spring is 735 N/m.
Explanation:
It is given that,
Mass of fruit, m = 1500 g = 1.5 kg
Compression in the scale, x = 0.02 m
We need to find the force constant of the spring on the scale. The force acting on the scale is given by using Hooke's law. So,
Also, F = mg
k is force constant
So, the force constant of the spring is 735 N/m.
Explanation:
It is given that,
Distance, r = 3.5 m
Electric field due to an infinite wall of charges, E = 125 N/C
We need to find the electric field 1.5 meters from the wall, r' = 1.5 m. Let it is equal to E'. For an infinite wall of charge the electric field is given by :
It is clear that the electric field is inversely proportional to the distance. So,
E' = 291.67 N/C
So, the magnitude of the electric field 1.5 meters from the wall is 291.67 N/C. Hence, this is the required solution.
Answer:
5N
Explanation:
(25 N - 20 N = 5 N)
