Which statement best describes how scientists and engineers work together

Physics
1 answer:
alexandr402 [8]3 years ago
6 0

Answer:

Option D: Engineers come up with scientific questions when they are

developing their design, and scientists do research to answer

them.

Explanation:

Normally, scientists work involves study of how nature works while engineers work is to create new things, such as websites, products e.t.c. Now, the objectives of engineers and scientists are different because they follow different processes while working to achieve their results. Scientists perform experiments using the scientific method which involves processes such as constructing hypothesis and testing with an experiment while, engineers usually follow the creativity based design engineering processes which involves developing of prototype solutions and testing those solutions.

Thus, it's clear that engineers deal with design while scientists deal with research.

The correct answer will be option D

Which si unit whould be most appropriate for describing the length of a shoe?
aniked [119]

Answer:

Milimeters

Explanation:

This kind of question must be checked with everyday elements, in this way we will analyze each of the options until we reach the appropriate:

kilograms can not be because this unit serves to measure the mass not the length.

kilometers (km) is a unit of length, but however it does not serve for this measurement since a km is equivalent to 1000 meters, therefore measuring the length of a shoe with a ruler measuring 1000 meters is very impractical.

milliliters is a unit of volume, and can often be found in the measurement of volume content of liquids, for example 700 milliliters of milk or 1000 milliliters of water. Therefore it is impractical to measure a shoe with a unit of volume.

In this way the way to measure a shoe correctly is using a ruler or measuring instrument graduated in millimeters.

A starship blasts past the earth at 2.0*10^8 m/s .Just after passing the earth, the starship fires a laser beam out its back of
Vilka [71]

Answer:

at the speed of light (c=3.0\cdot 10^8 m/s)

Explanation:

The second postulate of the theory of the special relativity from Einstein states that:

"The speed of light in free space has the same value c in all inertial frames of reference, where c=3.0\cdot 10^8 m/s"

This means that it doesn't matter if the observer is moving or not relative to the source of ligth: he will always observe light moving at the same speed, c.

In this problem, we have a starship emitting a laser beam (which is an electromagnetic wave, so it travels at the speed of light). The startship is moving relative to the Earth with a speed of 2.0*10^8 m/s: however, this is irrelevant for the exercise, because according to the postulate we mentioned above, an observer on Earth will observe the laser beam approaching Earth with a speed of c=3.0\cdot 10^8 m/s.

Find the wavelength of a 26 Hz sound wave traveling through air at 20ºC. Hint: speed of sound at 20ºC = 343 m/s
Usimov [2.4K]
The correct answer for the question that is being presented above is this one: "B. 13m." 

The formula of wave velocity is this:
wave velocity = f * <span>λ
</span>λ = v / f
<span>λ</span> = 343m/s / 26Hz
λ = 13.20m .. ans (b) 

Here are the following choices:
A. 5m 
B. 13m 
C. 28m 
D. 58m
