The correct answer to the question is D.Biosphere


Every planet has it's own gravity.Hence, they have their own atmosphere.The concentration of particles and gases may vary from planet to planet depending on their force of gravity.

Every planet contains the lithosphere,the hard and  rigid outer layer which contains the crust and mantle.  

Earth is the only habitable planet which supports biosphere.Its atmosphere contains 20% of oxygen along with nitrogen which are responsible for sustaining various types of flora and fauna as well as evolution of new species.

The acceleration produced by a net force on a body is inversely proportional to the mass of the body. true or false
ExtremeBDS [4]
Hi! This is true because F = mA. If we increase mass, we should expect acceleration to be lower. If we decrease mass, we should expect acceleration to increase. Think of it this way - it is harder to make a heavier person go faster then slower and faster again.

<h3>What is Quadratic equation ?</h3>

A quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic equation is y = ax^{2} + bx + c, where a, b, and c are numbers and a cannot be 0

P(A) = 0.006 a^{2} - 0.02a + 120

123 = 0.006- 0.02a + 120

0=0.006 a^{2} - 0.02a - 3

you can use the quadratic equation  formula to solve for the man's age.

A = (-b ± (\sqrt{b^{2} - 4*a*c})  ) / (2a)

A = (0.02 ±  \sqrt{(-0.02)^{2} - 4*0.006*(-3)}/ (2*0.006)

A = (0.02 ± \sqrt{0.0076}) / 0.012

A = 9 , -5.67

Age of the man will be 9 years

During a 400-m race, a runner crosses the 100 m mark with a velocity of 12 m/s. What would be her final position if she maintain
Cerrena [4.2K]

Answer:

Explanation:

Given that

Total race distance is 400m

Her initial velocity was 0m/s²

At the 100m mark, after she has travelled 100m, her final velocity was v=12m/s²

Using equation of motion

Let determine her constant acceleration

v²=u²+2as

12²=0²+2×a×100

144=0+200a

144=200a

a=144/200

a=0.72m/s²

Then we want to know her position after another 10second

So total time is 10+12=22seconds

Then, using equation of motion

Let determine his postion

S=ut+½at²

S=0•t+½×0.72×22²

S=0+174.24

S=174.24 m

Her position will be 174.24m
