Answer:

A.) Launch a satellite

Explanation:

Landing on the moon takes years to figure out. (How, when, what is the purpose,  etc.)  Capturing an asteroid is beyond difficult and would also take years to figure out how to do so.

Launching a space probe has yet to be done BUT we have had a satellite launched (hence how we get satellite images.)

Bacteria and viruses are inactivated by temperatures above 139 ∘C in an autoclave. An autoclave contains steam at 1.00 atm and 1
andrezito [222]
To answer this question, we will use pressure law which states that:
"At constant volume of a fixed mass of gas, the pressure of the gas is directly proportional to the temperature"

This means that:
Pi / Ti = Pf / Tf where:
Pi is the initial pressure = 1 atm
Ti is the initial temperature = 100 + 273 = 373 degree kelvin
Pf is the final pressure that we want to calculate
Tf is the final temperature = 139 + 273 = 412 degree kelvin

Substitute in the equation with the givens to calculate the pressure as follows:
1 / 373 = Pf / 412
Pf = (1/373) * 412 = 1.104557641 atm

The heat capacity of water is 1cal degree'g1 (1 calorie per degree centigrade, per gram). You are given 1 gallon of water at 25
sdas [7]

Answer:

The heat needed to boil 1 gallon of water is 81,490.62 Joules.

Explanation:

Q=mc\Delta T

Where:

Q = heat absorbed or heat lost

c = specific heat of substance

m = Mass of the substance  

ΔT = change in temperature of the substance

We have :

Volume of water = V = 1 gal = 4546.09 mL

Density of water , d= 1 g/mL

mass of water = m = d × V = 1g/mL × 4546.09 mL =  4546.09 g

Specific heat of water = c = 1 Cal/g°C

ΔT = 100°C - 25°C = 75 °C

9 (boiling pint of water is 100°C)

Heat absorbed by the water to make it boil:

Q= 4546.09 g\times 1 Cal/g^oC\times 75^oC=340,956.75 Cal

1 calorie = 4.184 J

Q=\frac{340,956.75}{4.184} J = 81,490.62 J

The heat needed to boil 1 gallon of water is 81,490.62 Joules.

Describe the location of a proton within an atom. Compare the mass of a proton in regard to other subatomic
const2013 [10]

Explanation:

Protons are the positively charged particles found in an atom.

  • A proton is found within the nucleus of an atom.
  • Together with the neutron, they make up the nuclear region of an atom.

Protons and neutrons constitutes the bulk mass of the atom.

 The mass of a proton is 1.67 x 10⁻²⁷kg

The proton have the same mass as neutrons.

Compared to electrons, it is 1840 times the mass of an electron.
