Answer:

Using the Lunar Module to travel back to Earth

Explanation:

During the Apollo 13 Mission (Launched on April 11, 1970), two days in the mission on the way to the Moon, an explosion occurred in the oxygen cylinder of the Service Module due to which Lunar landing was aborted and a quick plan was devised to bring back the Astronauts alive on Earth.

The oxygen tank of service module was used to generate electrical power and provide breathable air in the command module. The command module became uninhabitable because of quick loss of oxygen in the service module. Due to this the only option was to use the Lunar Module to get back on Earth.

Lunar module was designed to support 2 Astronauts for 2 days on Moon. A lot of procedures were drafted by Mission Control, Houston so that it could support 3 astronauts for 4 days. Although the crew faced a lot of challenges and hardships during the return journey, they came back on Earth safely after going around Moon and making a record of farthest space travel by any human being. The capsule carrying the crew , splashed in South Pacific ocean on April 17, 1970.

3. An airplane is heading north with an airspeed of 325 m/s with a wind from the east at 55.0 m/s. What is the airplane's veloci
liraira [26]

Let <em>a</em> denote the airplane's velocity in the air, <em>g</em> its velocity on the ground, and <em>w</em> the velocity of the wind. (Note that these are vectors.) Then

<em>a</em> = <em>g</em> + <em>w</em>

and we're given

<em>a</em> = (325 m/s) <em>j</em>

<em>w</em> = (55.0 m/s) <em>i</em>

Then

<em>g</em> = - (55.0 m/s) <em>i</em> + (325 m/s) <em>j</em>

The ground speed is the magnitude of this vector:

||<em>g</em>|| = √[ (-55.0 m/s)² + (325 m/s)² ] ≈ 330. m/s

which is faster than the air speed, which is ||<em>a</em>|| = 325 m/s.

What intermolecular force is responsible for the attraction between an ion and a polar molecule?
Pani-rosa [81]

Answer:

Dipole ion forces

Explanation:

Dipole ion forces are attractive forces between an ion (an atom that has lost or gained an electron, so it has a charge) and a polar molecule. A molecule is a dipole when there is an asymmetric distribution of electrons because the molecule is made up of atoms of different electronegativity. The ion then attaches to the part of the molecule that has its opposite charge: the positive end of the polar molecule faces the anion (negatively charged ion) and the negative end of the polar molecule faces the cation ( positively charged ion).

I think least electricity is used between probably 7-8a.m. and 4-5p.m.

This is because, around those times, the suns already out. Depending on how sunny it is, it may not be as cold as all the other times of the day. And by then, buildings are typically already warmed all up. Everybody's body heat also may play a factor in buildings. ( if there is a ton of people )

An observer notices that 12 waves pass by in 4 seconds. What is the frequency of these waves? 0.33 Hz 16 Hz 48 Hz 3 Hz
Dennis_Churaev [7]

Answer:

Frequency = 3 Hz

Explanation:

Frequency is a measure of Hertz. Recall that Hertz is the unit expressing cycles/second, where one second is the denominator of the fraction for simplicity. If there are 12 waves every four seconds, and one wave represents one cycle, dividing 12 waves by 4 seconds will give the answer of 3 waves (or cycles) per one second.
