List three limitations of human space travel

2 answers:

One of the biggest problem is radiation. Once you get out if the earth's magnetic field you have your astronauts exposed to solar radiation.
Even sending a team to mars is not possible because the radiation would almost certainly kill them. Until some way is figured out to shield the astronauts from the sun's radiation and other cosmic radiation we are pretty much stuck.

another limitation is the span of the human life. assuming that you want to go outside of the solar system, it is much too far to travel for a human.
in addition there is the speed limitation. of course, Einstein predicts that in order to travel at the speed of light, the substance must have no mass. therefore, it is impossible for a human - let alone a spaceship - to travel at that speed, crushing our dreams of interstellar travel (in a human lifespan).

Write a structural formula for 1-pentanol, the alcohol derived from pentane, by making a substitution on one of the carbon atoms

DedPeter [7]

To yield an alcohol from an alkane, one reaction could be from alkyl halide through hydrolysis reaction. The alkyl halide should be pentyl chloride. When you add water to it, the OH⁻ ion will replace Cl to make 1-pentanol, while the Cl⁻ ion binds with H⁺ to form HCl. The main product is pentanol, while the by-product is HCl.

A city's water supply is contaminated with a toxin at a concentration of 0.63 mg/L. For the water to be safe for drinking, the c

Shalnov [3]

Answer:

Approximately 22.37 days, will it take for the water to be safe to drink.

Explanation:

Using integrated rate law for first order kinetics as:

$[A_t]=[A_0]e^{-kt}$

Where,

$[A_t]$ is the concentration at time t

$[A_0]$ is the initial concentration

k is rate constant

Given that:- k = 0.27 (day)⁻¹

$[A_0]$ = 0.63 mg/L

$[A_t]=1.5\times 10^{-3}$ mg/L

Applying in the above equation as:-

$1.5\times 10^{-3}=0.63e^{-0.27\times t}$

$63e^{-0.27t}=150\times \:10^{-3}$

$e^{-0.27t}=\frac{1}{420}$

$t=\frac{100\ln \left(420\right)}{27}=22.37$

Approximately 22.37 days, will it take for the water to be safe to drink.

a scuba diver's tank contains 0.29g of oxygen compressed into volume of 2.3L. What is the pressure in the tank at 9C?

viva [34]

Answer:

The answer to your question is P = 0.18 atm

Explanation:

Data

mass of O₂ = 0.29 g

Volume = 2.3 l

Pressure = ?

Temperature = 9°C

constant of ideal gases = 0.082 atm l/mol°K

Process

1.- Convert the mass of O₂ to moles

16 g of O₂ -------------------- 1 mol

0.29 g of O₂ ---------------- x

x = (0.29 x 1)/16

x = 0.29/16

x = 0.018 moles

2.- Convert the temperature to °K

Temperature = 9 + 273 = 282°K

3.- Use the ideal gas law ro find the answer

PV = nRT

-Solve for P

P = nRT/V

-Substitution

P = (0.018 x 0.082 x 282) / 2.3

-Simplification

P = 0.416/2.3

-Result

P = 0.18 atm

When the substance dissolves the solution is not transparent true or false

bogdanovich [222]

Answer:

Some substances dissolve when you mix them with water. When a substance dissolves, it might look like it has disappeared, but in fact it has just mixed with the water to make a transparent (see-through) liquid called a solution.
