Answer:

the distance between adjacent fringes is increased by a factor o 2

Explanation:

To find how the distance between fringes is modified you can use the following formula for the calculation of the distance between fringes:

\Delta y=\frac{\lambda D}{d}

D: distance to the screen

d: distance between slits

λ: wavelength of the light

if d is decreased by a factor of 2, that is d'=1/2d, you have:

\Delta y'=\frac{\lambda D}{d'}=\frac{\lambda D}{(1/2)d}=2\Delta y

hence, the distance between adjacent fringes is increased by a factor o 2

A 200-kg object has a 50-Newton rightward net force being applied to it. What is the magnitude of the rightward acceleration on
katovenus [111]
The formula for acceleration is force divided by mass.

Force = 50 N

Mass = 200 kg

Acceleration = ???

\frac{50}{200} = \frac{1}{4}

\frac{1}{4} = 0.25

~~

Acceleration = 0.25 m/s²

jek_recluse [69]

Answer:

A(n)  <u>living wage</u> is the idea that people should be able to purchase the essentials of life by working a forty-hour workweek. Many local municipalities have as a result set higher minimum wages than the federally mandated minimum wage to accomplish this goal.

Explanation:

Living wage is the idea given to reduce poverty specially in cities with higher costs. It's based on the fact that one who works forty hours per week, he or she should be able to afford the basic needs of life that includes the water, food and shelter. Research has shown that the implementation of this concept has played the role in reducing poverty and enhancing the quality of life of workers. Countries like New-Zealand and united kingdom has supported this concept.

The speed of sound is dependent on which of the following?
aleksandr82 [10.1K]
<span>Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. The speed of sound in room temperature air is 346 meters per second. so that would be answer A</span>

Katyanochek1 [597]
This means it doesn't change its velocity and it doesn't have momentum. 3. Examples of Newton's 1st Law  If you slide a hockey puck on ice, eventually it will stop, because of friction on the ice. It will also stop if it hits something, like a player's stick or a goalpost.

What qualifications do you need to be a research scientist?
Vedmedyk [2.9K]

The qualifications boil down to: College education.

In most university or industrial research organizations, you might be able to work there as a member of the team who doesn't get much pay or much respect, with research going on all around you directed by other people, after you've gotten you Master's degree.

But you really don't have a shot at leading anything, or having much to say about what's being researched or how, until you have a PhD degree in the field where you'd like to do the research.

(Did I mention how proud I was to be present about 6 weeks ago, in a land far away, when my daughter was awarded a PhD degree in Molecular Biology ? I didn't want to let you get away without hearing about that.)
