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.

Calculate the amount of charge necessary to exert a force of 35 N in an electric field of 300 N/C.

densk [106]

Answer:

The amount of charge is "0.117 C" i.e., option A.

Explanation:

The given values are:

Force,

$\vec{F}$ = 35 N

Electric field,

$\vec{E}$ = 300 N/C

Charge,

q = ?

As we know,

⇒ $\vec{F}=q\vec{E}$

On substituting the given values in the above formula, we get

⇒ $35=q\times 300$

⇒ $q=\frac{35}{300}$

⇒ $q=0.117 \ C$

Which of the following is the best paraphrasing of the Heisenberg uncertainty principle? Which of the following is the best para

weqwewe [10]

<h2>Answer:The more precisely you know the position of a particle, the less well you can know the momentum of the particle</h2>

The Heisenberg uncertainty principle was enunciated in 1927. It postulates that the fact that each particle has a wave associated with it, imposes <u>restrictions on the ability to determine its position and speed at the same time. </u>

In other words:

It is impossible to measure simultaneously (according to quantum physics), and with absolute precision, the value of the position and the momentum (linear momentum) of a particle.

<h2>So, the greater certainty is seeked in determining the position of a particle, the less is known its linear momentum and, therefore, its mass and velocity. </h2><h2 />

In fact, even with the most precise devices, the uncertainty in the measurement continues to exist. Thus, in general, the greater the precision in the measurement of one of these magnitudes, the greater the uncertainty in the measure of the other complementary variable.

A baseball travels a distance of 20 meter at a speed of 25m/s. How much time did it take?

Whitepunk [10]

The baseball takes 0.8 s to travel a distance of 20 m at a speed of 25 m/s.

<u>Explanation:</u>

It is known that speed is the rate at which any object covers a particular distance.

So $speed =\frac{\text { distance }}{\text { time }}$

Hence, it is known that speed is directly proportional to distance covered and inversely proportionate to the time taken to cover this distance.

Similarly, the time taken by any object to cover a distance is directly proportionate to the distance and inversely proportionate to the velocity of the object.

As the distance is given as 20 m and speed is given as 25 m/s, then the time can be easily obtained by finding the ratio of distance to speed.

Here,

$\text { Time }=\frac{\text {distance}}{\text {speed}}=\frac{20}{25}=0.8 \mathrm{s}$

Thus, the baseball takes 0.8 s to travel a distance of 20 m at a speed of 25 m/s.
