Answer:

Gran Telescopio Canarias

Explanation:

There are numerous giant telescopes all over the world which give us amazingly details data of the Universe. These work in various wavelengths. Talking about the telescopes which operates in visible wavelengths, the largest operational telescope will be Gran Telescopio Canarias. This telescope has an aperture of 10.4m. It is situated in Canary Island, Spain.

In future larger telescopes such as Thirty Meter Telescope and EELT will will make it look like a small telescope.

There are initially No nuclei in a radioactive source. After a time interval of three half-lives, what is the number of nuclei t

ladessa [460]

The number of nuclei that have decayed after three half-lives is 12.5% of the original mass.

<h3>What is half live of radioactive isotope?</h3>

The half life of a radioactive isotope is the time taken for the element to decay to half of its original mass.

<h3>Number of nuclei decayed after 3 half lives</h3>

N = N₀/(2³)

N = N₀/8

N = 0.125N₀

N = 12.5% of N₀

where;

N is n number of nuclei that have decayed after 3 half lives
N₀ is the original mass

Thus, the number of nuclei that have decayed after three half-lives is 12.5% of the original mass.

Calculate the average net force.

MrRa [10]

Answer:

<h2>given</h2>

mass = 3950 kg

speed= 25m/ sec

time= 10.5 sec

force

<h2>Solution</h2>

<h3>☄️Formula of force </h3>

$\fbox{f = m.a}$

To find the force we need to find the Acceleration first.

accleration= change in Velocity/time

accleration= 25/10.5

accleration= 2.38 m/sec²

put the value of accleration in the formula of force

force = Mass . accleration

force = 3950 x 2.38

<h3>☄️force = 9,401 Newton</h3>

7. A double-slit experiment uses coherent light of wavelength 633 nm with a slit separation of 0.100 mm and a screen placed 2.0

Illusion [34]

Answer:

The distance between first-order and second-order bright fringes is 12.66mm.

Explanation:

The physicist Thomas Young establishes through its double slit experiment a relationship between the interference (constructive or destructive) of a wave, the separation between the slits, the distance between the two slits to the screen and the wavelength.

$\Lambda x = L\frac{\lambda}{d}$ (1)

Where $\Lambda x$ is the distance between two adjacent maxima, L is the distance of the screen from the slits, $\lambda$ is the wavelength and d is the separation between the slits.
