Window ventilators are used for ensuring a supply of fresh air from the outside into the interior. They are used in rooms with natural ventilation, mechanical extract ventilation or hybrid ventilation. ... It automatically adjusts the inflow of fresh air depending on the level of relative humidity in the room.

Explanation:

Increased levels of oxygen in the atmosphere due to photosynthesis caused rates of weathering to increases which aided in the formation of soil.

The process in which use of solar energy occur by  plants, algae and certain bacteria convert them into chemical energy and starch called as photosynthesis.

Photosynthesis occur in chloroplast of the green plant which has its own DNA, genes and synthesize their own proteins.

photosynthetic Pigments are also involve in this process which is responsible for trapping sunlight present in chlorophyll pigment of chloroplast, like chlorophyll a, b and c.

some of the Bacteria have chlorophyll known as bacteriochlorophyll which can absorb infrared rays, Carotenoids which are yellow, orange or red-coloured pigments that absorb bluish-green light., Xanthophyll, Phycobilins.

We have to divide 2 by 232 and 327

232/2= 116    327/2=163

Answer:

The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move. Eventually, most of energy used by organisms is transformed into heat and dissipated.

Answer:

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. Thus, swimmers must stroke downward in the water to stay afloat and propel forward. This movement is equal and opposite to the force the water exerts against the swimmer to stop them from moving.

Answer:

gravity

Explanation:

Hi there!

[tex]\large\boxed{\text{B. 32.73N}}[/tex]

To calculate the tension, we must calculate the acceleration of the system.

Begin with a summation of forces:

∑F = -M₁gsinФ + T - T + M₂g

Simplify and solve for acceleration: (Tensions cancel out)

[tex]a = \frac{-M_1gsin\theta + T - T + M_2g}{M_1+M_2}[/tex]

Plug in values. Let g = 10 m/s²

[tex]a = \frac{-3(10)(sin30)+8(10)}{3+8} = 5.91 m/s^{2}[/tex]

Now, to find tension, let's sum up the forces acting on ONE block. For simplicity, we can look at the hanging block:

∑F = -T + W

ma = -T + W

Rearrange to solve for T:

T = W - ma

We know the acceleration, so plug in the values:

T = (8)(10) - (8)(5.91) = 32.73 N

Answer: As the light moves through the diamond, it is scattered and fractured, creating the sparkle that diamonds are known for. This is the refraction. ... This refraction and dispersion also creates natural light and dark areas in the refracted light, depending on where the light hits along the planes of the diamond

a). 1.2 s

b). 3.81 m

c) v= 6.8 m/s

d) v= 27.05 m/s

Speed is define as the distance per unit time. It is also define as how fast an object is  moving.

According to the question:

Height = 1.5 m , speed = 7.0 m/s.

a)By using 1st equation of motion

[tex]V = V_{0} + g*t.\\V = 0 \\V_{0} = 7.0 m/s.g = -9.8 m/s^2\\0 = 7 + (-9.8 m/s^2)*t\\t = 1.2 s[/tex]

b.

[tex]h = 1.5 + V_{0} *t + 0.5g*t^2\\V_{0} = 7.8 m/s\\t = 1.2s , g = -9.8 m/s^2\\h = 3.81 m[/tex]

c.

[tex]V^2 = V_{0} ^2 + 2g*d\\V_{0} = 7.8 m/s\\g= -9.8 m/s^2.\\d= 2.2-1.5 = 0.7 m\\V = 6.8 m/s[/tex]

d.

[tex]V^2 = V_{0} ^2 + 2g*h\\V_{0} = 0\\g = +9.8 m/s^2.\\h = 6.8 m\\V = 27.05 m/s[/tex]

This process is thought to have been the main source of energy for the sun in the early stages of its development before nuclear fusion reactions in the sun's core became the dominant source of energy.

Gravitational contraction is the process by which a celestial body, such as a star, generates energy through the release of gravitational potential energy as it contracts and becomes denser.

Here,
This process is thought to have been the main source of energy for the sun in the early stages of its development before nuclear fusion reactions in the sun's core became the dominant source of energy.

As the sun contracted and became denser, the temperature and pressure in its core increased, leading to the initiation of nuclear fusion reactions. These reactions transformed hydrogen into helium and released a tremendous amount of energy in the form of light and heat, which has sustained the sun for billions of years.
