If water is leaking from a certain tank at a constant rate, is it leaking at a rate that is greater than 12 liters per hour?(1 l
Margarita [4]

Answer:

Yes  it is possible because 3.33 is greater than 2.

Explanation:

Given that,

1 liter = 1000 milliliters

Suppose water is leaking from the tank at a rate that is greater than 2 milliliters per second.

We need to change the unit in ml/s

12 lit/hr=\dfrac{12000}{3600}

12 lit/hr=3.33\ ml/s

Hence, Yes  it is possible because 3.33 is greater than 2.

How long does it take oxygen to diffuse a distance of 1 mm in water at room temperature? How long does it take oxygen to diffuse
Viktor [21]

Answer:

option A

Explanation:

given,

travel distance = 1 mm

diffusion constant for the  molecule  of oxygen in water = 1 x 10⁻⁹ m²/s

we know that

 t = \dfrac{x^2}{2D}

t is the time taken for diffusion

x = 1 mm = 10⁻³ m

D is the diffusion

 t = \dfrac{(10^{-3})^2}{2\times 10^{-9}}

 t = \dfrac{(10^{3})}{2}

        t = 500 s

so, the option to the answer is 170 s

the correct answer is option A

Angling of the focal track of the anode to create a large actual focal spot and a smaller effective focal spot describes (the):
Vsevolod [243]

Angling of the focal track of the anode to create a large actual focal spot and a smaller effective focal spot describes the line focus principle

<h3>What is the line focus principle?</h3>

The line focus principle states that as the anode angle is reduced, the actual focal spot also becomes small but the heat loading is increased.

It also explains the relationship between the anode surface and the effective focal spot size.

As a result of this, by angling the target, effective area of the target is made much smaller that the actual area of electron interaction.

Hence, angling of the focal track of the anode to create a large actual focal spot and a smaller effective focal spot describes the line focus principle.

Describe one new piece of information that you learned about one of the featured scientist
statuscvo [17]

Answer:

<u>Development in science:</u>

There a number of individuals in the world around us who has improved the field of science and made it easy for us to know this universe more easily then ever. This universe is still unexplored and there are going to be more then billions of stars which are still not studied and has an immense amount of information regarding the universe.

<u>Stephen Hawking:</u> The scientist who made it easy for each of us to know the universe and more over the cosmos in a more detailed form, as before this no one knew about the different patterns of entities and there properties.

<u>A genius who was handicapped:</u>

He was a genius in cosmology, mathematics, and other subjects of science as he was diagnosed by the amyotrophic lateral sclerosis(ALS), which made it unable for him to live a normal life.But, he communicated through a computer which detected his nerve signals and shared his thoughts about any thing or subject.

<u>Why him?</u>

Stephen hawking was just tremendous in making it more understandable about the black holes, time worms, and space etc.As it was known to very small number of people before he took the stage.
