“Energy from the sun tends to affect only a small part of Earth's system."
Answer: False
Explanation: The sun is one of earths primary energy sources. Without the sun, all animals, plants, humans would die. The sun's energy provides warmth for humans and plants and animals cannot grow without the sun.
The statement "Energy from the sun tends to affect only a small part of Earth's system" is false.
What energy comes from the sun to Earth?The sun emits several forms of energy, including visible light, ultraviolet radiation, infrared radiation, and X-rays. Of these, visible light is the most abundant form of energy that reaches the Earth's surface.
The visible light from the sun provides the energy that drives the Earth's climate and weather patterns, powers photosynthesis in plants and algae, and is responsible for the colors we see in the world around us.
In addition to visible light, the sun also emits ultraviolet (UV) radiation. Some of this UV radiation is absorbed by the Earth's atmosphere, which helps to protect us from its harmful effects, but some of it reaches the Earth's surface and can cause skin damage and other health problems.
The sun also emits infrared radiation, which is responsible for heating the Earth's surface and atmosphere. This heat is important for the Earth's climate and weather patterns and is also used to generate electricity in solar power plants. The energy from the sun is essential for life on Earth and has a major impact on virtually every aspect of the Earth's system.
Here in the Question,
Energy from the sun has a major impact on the entire Earth system, from the atmosphere to the oceans to the land surface. The energy from the sun drives the Earth's climate and weather patterns, it powers the hydrologic cycle and drives ocean currents, and it provides the energy for photosynthesis, which is the basis of the Earth's food chain.
The energy from the sun that reaches the Earth's surface is also responsible for many physical and chemical processes that occur in the Earth's crust and upper mantle. For example, the energy from the sun powers the movement of tectonic plates, which leads to earthquakes, volcanic eruptions, and the formation of mountains.
The energy from the sun affects virtually every aspect of the Earth's system, from the smallest microorganisms to the largest geological features.
Therefore, the statement "Energy from the sun tends to affect only a small part of Earth's system" is false.

Explanation:
If water is flowing in a 1-inch diameter pipe with an average velocity of 3 m/s and the wall roughness is 400 microns, calculate the wall shear stress.
Answer:
Shear stress is 50.63 Pascal
Explanation:
As we know shear stress = [tex]\frac{\rho V^2 f}{8} \\[/tex]
Rho is the density
V is the velocity
f is the value from Moody's chart
We will know determine Reynolds number to determine the flow type and then the f value
[tex]R_e = \frac{ \rho*V*D}{u}[/tex]
[tex]R_e = \frac{1000*3*0.0254}{0.001} = 76200[/tex]
This is a turbulent flow and hence the roughness index is [tex]\frac{E}{D} = 0.0157[/tex], From this we get f = 0.045
Now shear stress = [tex]\frac{1000 * 3^2 * 0.045}{8} = 50.63[/tex] Pa

Example 1. An iron ball of mass 3 kg is
released from a height of 125 m and falls
freely to the ground. Assuming that the
value of g is 10 m/s2, calculate
(i) time taken by the ball to reach the
ground
(ii) velocity of the ball on reaching the
ground
(iii) the height of the ball at half the time it
takes to reach the ground.
According to the equations of motion, the time taken to reach the ground is 5 seconds.
Using;
s = ut + 1/2gt^2
s = distance
u = initial velocity
t = time taken
g = acceleration due to gravity
Note that u = 0 m/s since the object was dropped from a height
Substituting values;
125 = 1/2 × 10 × t^2
125 = 5t^2
t^2 = 125/5
t^2 = 25
t = 5 secs
Velocity on reaching the ground is obtained from
v = u + gt
Where u = 0 m/s
v = gt
v = 10 × 5
v = 50 m/s
At half the time it takes to reach the ground;
s = ut + 1/2gt^2
Where u = 0 m/s
s = 1/2gt^2
s = 1/2 × 10 × (2.5)^2
s = 31.25 m

una pieza pesa 80N al aire, posteriormente se sumerge completamente en glicerina, ¿cuál es el peso dentro de la glicerina si el volumen desalojado es de 1280cm3 y la densidad de la glicerina es de 1200kg/cm3?
Answer:
El peso de la pieza dentro de la glicerina es 64.93 N.
Explanation:
El principio de Arquímedes nos indica que “todo cuerpo sumergido dentro de un fluido experimenta una fuerza ascendente llamada empuje, equivalente al peso del fluido desalojado por el cuerpo”.
Entonces, el peso del cuerpo dentro del fluido (peso aparente) será igual al peso real que tenía fuera de él (peso real) menos el peso del fluido que desplaza al sumergirse (peso del fluido o fuerza de empuje). Matemáticamente se expresa como:
Paparente=Preal−Pfluido
El peso del fluido desplazado o fuerza de empuje ejercida por el líquido está dada por la expresión:
Pfluido = ρliq • Vcpo • g
en donde:
Vcpo = el volumen que desplaza el cuerpo ρliq = la densidad del líquido donde se sumerge el cuerpo g = 9.81 m/s²Entonces, en este caso:
Paparente= 80 N - 1200 [tex]\frac{kg}{m^{3}}[/tex]* 0.001280 m³* 9.81 [tex]\frac{m}{cm^{2} }[/tex]
Resolviendo:
Paparente= 64.93 N
El peso de la pieza dentro de la glicerina es 64.93 N.

Explanation:
Name the type of component that has a greater resistance as the current through it increases
Answer:
filament bulb, filament lamp
Explanation:
More length of a wire is a component that has a greater resistance as the current through it increases.
The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions present in the wire as they pass through. The moving electrons can collide with the ions present in the metal.
This makes more difficult for the current to flow and causes resistance in the wire so we can conclude that more length of a wire is a component that has greater resistance as more current passes through it.

Light is incident perpendicularly from air onto a liquid film that is on a glass plate. The liquid film is 70.2 nm thick, and the liquid has index of refraction 1.50. The glass has index of refraction 1.40. Calculate the longest visible wavelength (as measured in air) of the light for which there will be totally constructive interference between the rays reflected from the top and bottom surfaces of the film. Assume that the visible spectrum lies between 400 nm and 700 nm.
Answer:
λ₀ = 421.2 10⁻⁹ m
Explanation:
This is an exercise in constructive interference by reflection, let's review some concepts:
* When a ray goes from a medium with a lower index to one with a higher index, it undergoes a phase change of 180º, in this case we have a phase change from the air to the film
* Within the material the wavelength changes according to the spare part index of the material
λₙ = λ₀ / n
By including these two aspects, the constructive interference equation remains
2 n t = (m + ½) λ₀
λ₀ = [tex]\frac{2nt}{m+ \frac{1}{2} }[/tex]
we substitute
λ₀ = 2 1.50 70.2 10⁻⁹ / (m + ½)
let's substitute some values of m
m = 0
λ₀ = [tex]\frac{210.06}{0.5}[/tex] 10⁻⁹
λ₀ = 421.2 10⁻⁹ m
is in the visible range
m = 1
λ₀ = [tex]\frac{210.6}{1+0.5}[/tex] 10⁻⁹
λ₀ = 140.4 10⁻⁹ m
This outside visible range, is ultraviolet light
