Seen through a traditional optical telescope, the space between stars and galaxies is pitch black. But, with a radio telescope,
Gemiola [76]

That's the Cosmic Microwave Background (CMB). (D)

It doesn't "provide evidence for the ... Theory". The Big Bang theory is the best explanation (so far) for the CMB and a lot of other observations.

Evidence isn't used to prove theories. Theories are attempts to explain evidence.

omeli [17]
The correct answer is remain the same because if the particles and temperature remain constant, when the pressure increases the temperature is not increasing so it would just stay the same

How much must a man weigh (force) if the pressure he exerts while standing on one foot which has an area of 25 m^2 exerts a pres
andriy [413]

Answer:

Weight, W = 125 N

Explanation:

Pressure, P = 5 Pa

Area, A = 25 m²

We need to find how much must a man weigh (force) if the pressure he exerts while standing on one foot which has an area of 25 m² exerts a pressure of 5 Pa. So,

Pressure = force/area

So,

F=P\times A\\\\F=5\times 25\\F=125\ N

So, the weight of the man is 125 N.

Which line could be added to show the difference a digita leader can make?
tia_tia [17]

Question: I was honored to be a part of an online group of students from the United States, Africa, and China seeking solutions to water shortages. While we all had great enthusiasm about changing the world, the project quickly dissolved because no one was willing to listen to differing viewpoints.

Which line could be added to show the difference a digital leader can make?

Answer:

The line that can be added to show the difference a digital leader can make is, "We saved the project by allowing each group to share their thoughts and then chose the best solutions"

Explanation:

A digital leader is the one who is innovative, creative, collaborative, experimental, curious and also able to network. The person should have forward thinking capability, most importantly should remain very adaptive, so that can remain relevant to the change. To archive this, he alone can do this. Must have different group of people through which could extract different ideas and views from which he/she could chose the right one for the desired situation.

An object in free fall near the surface of the earth accelerates at a rate of 78979.4 mi/hr What is the rate of acceleration for
Nina [5.8K]

Answer:

32.176 ft/s²

9.807 m/s²

Explanation:

Data provided in the question:

Acceleration of the free falling object = 78979.4 mi/hr²

a) In ft/s

Now,

1 mi = 5280 foot

and,

1 hour = 3600 seconds

thus,

78979.4 mi/hr = \frac{\textup{78979.4}\times\textup{5280}}{\textup{1}\times\textup{3600}^2}

or

78979.4 mi/hr = 32.176 ft/s²             ...............(1)

b) In m/s²

Now,

1 foot = 0.3048 m

thus,

we have from 1

32.17 ft/s² =  \frac{\textup{32.17}\times\textup{0.3048}}{\textup{1}\times\textup{1}^2}

or

78979.4 mi/hr = 32.176 ft/s²  = 9.807 m/s²
