To imagine that you were chosen to fly the first space shuttle that could travel at the speed of light and write a story about the trip, it is necessary to research astronomy in more detail to generate a more consistent essay.
<h3 /><h3>What would it be like to travel at the speed of light?</h3>
In science fiction films, it is common to portray stars as white, illuminated and stretched lines, demonstrating speed, but this is an unfounded reasoning, since light has no color and stars do not move at that speed.
Therefore, a trip at the speed of light would be common, the only difference would be the reduction of time when arriving at the places, as for example, according to research, a trip from Earth to Pluto at the speed of light would take about five and a half hours.
It would also not be possible to see the stars as in the movies, as their photons are not visible.

Answer:
- Question 1: You cannot make sure the ballon will not burst before it reaches 3,000m altitude because the volume will exceed 47.0 liters
Explanation:
<u>1. Data</u>
- Maximum volume of the balloon: 47.0 liters
At 3,000 m:
- Temperature at 3,000 m, T₁: 6.0ºC
- Pressure at 3,000m, P₁: 0.565atm
At ground:
- Temperature at ground, T₂: 20ºC
- Pressure at ground, P₂: 765mmHg
- Volume at ground, V₂: 30.0 liters
Questions:
- Will the balloon's volume be more than 47.0 liter?
- Amount in grams of helium in the ballon:?
<u>2. Unit conversions:</u>
a) Convert P₂ to atm:
- P₂ = 765mmHg × 1 atm/760.0mmHg = 1.00657895atm
b) Convert the temperatures to kelvin:
- T₁ = 6.0 + 273.15 = 279.15K
- T₂ = 20 + 273.15 = 293.15K
<u>3. Solution</u>
Question 1.
<u>Calculate the final volume of the balloon:</u>
Since the number of moles of helium gas inside the balloon remains unchanged, pV = nRT yields the combined gas law:
From which you can solve for V₁ and compute it:
Then, the volume of the balloon will exceed the gurantee of the manufacturer.
Question 2.
<u>a) Calculate the number of moles of helium</u>
<u>b) Calculate the mass in grams of helium</u>
<u />
Use the atomic mass of helium: 4.003g/mol
- mass = number of moles × molar mass
- mass = 1.2558mol × 4.003g/mol = 5.02g
Rounding to 2 significant figures: 5.0g
Explanation:
If velocity is increasing uniformly with time, this means the acceleration is constant. So we can use this formula,
Initial Velocity+Final Velocity/2.
Our total Velocity is 60 m/s. Let convert minutes to seconds, which is 120 seconds so we get
60m/s/120 s which we get 0.5 m/s.
Average velocity is 0.5 m/s^2.
