Which is associated with a fission reaction? *
podryga [215]

Answer: Radioactive waste

Explanation:

The nuclear fission reaction consists of heavy atomic particles or heavy nucleus, like plutonium and uranium and in radioactive heavy metals. In the fission reaction the nucleus get split into equal masses of particles. This process is associated with release of large amount of energy. The fission of radioactive waste can cause deadly mutations in living beings.

An expandable container of oxygen has a volume of 30.0mL at a pressure of 36.7psi. If the pressure of the oxygen is reduced to 2
ELEN [110]

Answer:44.04mL

Explanation:Parameters given

V1 = 30.0mL

P1 = 36.7psi

P2 = 25.0psi

V2 = ??

From Boyle's gas law, which states that "the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature"

This means that,

the pressure of a gas tends to increase as the volume of the container decreases, and also the pressure of a gas tends to decrease as the volume of the container increases.

Mathematically, Boyle's can be represented as shown below

P= k/V

Where P = Pressure, V = Volume and k is constant

Therefore,

PV = k

P1V1 = P2V2 =PnVn

Using the formula

P1V1 = P2V2

V2 = P1V1/P2

V2 = (36.7psi × 30.0mL) / 25.0psi

V2 = 1101.0/25.0

V2 = 44.04mL

faust18 [17]

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.

A geology student found an irregularly shaped rock, with a mass of 28.63 grams, and placed it into a graduated cylinder with a v
EastWind [94]

Density is simply the ratio of mass over volume. In this case, the volume of the rock is the difference of after and before it was dropped into the cylinder.

volume = 19.73 mL – 13.31 mL = 6.42 mL

 

density = 28.63 g / 6.42 mL

<span>density = 4.46 g/mL</span>
