Which technology is NASA developing that will help astronauts reach Mars? Corona Freedom Orion Skylab
stiv31 [10]

Answer:

The answer is "Orion technology"

Explanation:

NASA tested that perhaps the abort system on the Biomechanical properties fires faster than that of the rocket, possibly costing colonists during launch or a crisis. It test is a significant step forward in Agency's plans again for the Artemis space mission, which will pave the way for human missions to The moon. NASA is building a humanoid spacecraft for long-range space missions for the first time in generations.  As just a result, they are beginning a new age of space travel. Orion would be used to transport the crew into space as a surveillance vehicle. Also, it helps astronauts to flights and ensures a safe return to orbit in the case of an emergency release.

Below are 10 different metric prefixes and their abbreviations. Match them up. :)
Sladkaya [172]

Answer:

1.G → giga  

2.da → deca

3.n → nano

4.m → milli

5.M → mega

6.k → kilo

7.c → centi

8.d → deci

9.h → hecto

10.µ → micro

Explanation:

In descending order:

1.G → giga (1 . 10⁹)  

5.M → mega (1 . 10⁶)

6.k → kilo (1 . 10³)

9.h → hecto (1 . 10²)

2.da → deca (1 . 10¹)

8.d → deci (1 . 10⁻¹)

7.c → centi (1 . 10⁻²)

4.m → milli (1 . 10⁻³)

10.µ → micro  (1 . 10⁻⁶)

3.n → nano (1 . 10⁻⁹)

In example:

1000000 m = 1 Mm

0,000000001 m = 1 nm

This graph represents a population of molecules in a gas versus the distribution of the average velocity(speed) of its molecules
pshichka [43]

Answer:

Part A

Given that the graph is symmetrical and bell shaped, the average kinetic energy is given by the midline of graph, which corresponds to the common speed of the highest number of the population

Part B

The formula for the average kinetic energy, K.E. = (3/2)·(R/NA)·T

Therefore, the part of the graph that indicates the temperature of the sample is the average kinetic energy. K.E.

Part C

At a lower temperature, the heat is less evenly distributed and we have the distribution T2 higher than T1

In the 17th century, Newton proposed that light was a stream of particles. The wave-particle debate continued for over 250 years
leonid [27]

Light as a wave

  • Young's Double Slit Experiment.
  • Davisson-Germer Experiment

Light as a particle

  • Einsteins Photoelectric Effect Phenomenon
  • Diffraction Phenomenon of Particles

<h2>Define the following terms:-</h2><h3> 1)Photoelectric Effect</h3>

Electrons are released when a material is exposed to electromagnetic radiation, such as light, and this is known as the photoelectric effect. These electrons are referred to as photoelectrons.

<h3>2)Diffraction </h3>

When a wave hits a wall or an opening, several phenomena known as diffraction take place. It is described as the interference or bending of waves through an aperture into the region of the geometric shadow cast by the obstruction or aperture.

<h3>3)Davisson-Germer Experiment</h3>

In the Davisson-Germer experiment, conducted by Clinton Davisson and Lester Germer between 1923 and 1927 at Western Electric (later Bell Labs), electrons scattered by a nickel-metal crystal's surface showed a diffraction pattern. This was an experimental turning point in the development of quantum mechanics and supported the wave-particle duality concept first put forth by Louis de Broglie in 1924.

<h3>4)Young's Double Slit Experiment.</h3>

One of the most significant physics experiments was Young's Double Slit experiment. Thomas Young directed it in 1801. Despite the fact that Huygens' experiment had demonstrated that light has a wave character, the light at the time was still thought of as a beam of particles due to Newton's renown.
