In 2021 the James Webb Telescope will begin operation focusing on infrared wavelengths and must be kept extremely cold.

<h3>What is James Webb Telescope?</h3>

The James Webb Telescope is the most important optical telescope present in space, which is employed by astronomers to observe celestial bodies and physical phenomena in the universe.

This space telescope (James Webb Telescope) is based on the infrared wavelengths that cover a specific length of 0.57 to 28-micrometer waves and enable to observe different spectra across the Universe.

In conclusion, in 2021 the James Webb Telescope will begin operation focusing on infrared wavelengths and must be kept extremely cold.

Fittoniya [83]

Answer:

118.776 mmHg

Explanation:

The equation of the reaction is;

C4H10(g) + 13/2 O2(g) ------> 4CO2(g) + 5H20(g)

Now the mole ratio according to the balanced reaction equation is;

1 : 6.5 : 4 : 5

Hence, the total number of moles present = 1 + 6.5 + 4 + 5 = 16.5 moles

Mole fraction of water vapour = 5/16.5 = 0.303

We also know that;

Partial pressure= mole fraction * total pressure

Partial pressure of H20(g) = 0.303 * 392 mmHg = 118.776 mmHg

Answer:

As the temperature of the water increases, the time needed for the dye to spread decreases. This is because the kinetic energy between the liquid particles increases, therefore helping the dye to dissolve and spread throughout the water.

rusak2 [61]

5. 25 x 10⁻⁷mg

Explanation:

This is mass conversion from mg to kg;

The kg is a quantity of mass used to measure the amount of matter in a substance.

Given mass = 5.25 x 10⁻¹³kg

The kilo- is a prefix that denotes 10³

therefore;

1000g = 1kilogram

the milli- is a prefix that denotes 10⁻⁻³

1000mg = 1g

Now that we know this, we can convert:

5.25 x 10⁻¹³kg x $\frac{1000g}{1kg} x \frac{1000mg}{1g}$ = 5. 25 x 10⁻¹³ x 10⁶mg

= 5. 25 x 10⁻⁷mg
