Answer:The correct answer is30%.

Explanation:

Earth's albedo tells us about the how much energy absorbed from sun's radiation remains on the planet Earth and how much much energy absorbed is reflected back into space by its atmosphere.

About 30 % of the energy from the sun radiations falling on the Earth is reflected by the earth atmosphere back into the space.

A body of mass 2.78 kg is pushed straight upward by a 31.3 N vertical force. What is its acceleration (in m/s2)
Bingel [31]

To solve this problem we will apply the concepts related to Newton's second law for which the product of mass and acceleration is defined as the force applied to an object. Mathematically this is,

F_{net} = ma \rightarrow a = \frac{F_{net}}{m}

Here,

F_{net} = Net external Force

m = Mass of the body

a = Acceleration

The net force on the body would be given by the difference between the ascending force and the weight, therefore,

F_{net} = F-W

Here,

F = Upward Force

W = Weight

The Weight is,

W = (2.78kg)(9.81m/s^2)

W = 27.27N

Then the F_{net} is

F_{net} = 31.3-27.27

F_{net} = 4.03N

Finally replacing at the first equation we have,

a = \frac{4.03N}{2.78kg}

a = 1.44m/s^2

Therefore the acceleration of the stone is 1.44m/s^2

87% of men in the Silent Generation were employed when they were young. Predict: What percentage of Millennial men do you think
olga nikolaevna [1]

The 66 percent of Millennials were employed in the year 2018.

<h2>Millennials </h2>

Millennials are the people who are born between 1982 and 1998 while on the other hand, 87% of men in the Silent Generation were employed so there is a decrease occur in the employment rate from silent generation to Millennial generation.

<h3>Reason</h3>

The reason behind this decrease is the unavailability of employment opportunities and jobs for the people of Millennial generation so we can conclude that 66 percent of of Millennial men were employed in the year 2018.

So, a = 50

triangle CAB = a+a+x=180

CAB = 50+50+X=180

CAB = X = 180-100

X=80
