D. Chlorofluorocarbon

This is a man-made carbon that causes the gradual thinning(deception) in the earth’s Ozone layer.

Hope this helped and pls mark as brainliest!

Which statement explains what causes the balloon to accelerate

victus00 [196]

The air leaving through the balloon's mouth pulls the balloon in the same direction as the exiting air, so the balloon experiences a net force. All air surrounding the balloon pushes the balloon forward.

A particle travels along a straight line with a velocity v = (12 – 3t2) m/s. When t = 1 s, the particle is located 10 m to the l

arlik [135]

Answer:

The displacement from t = 0 to t = 10 s, is -880 m

Distance is 912 m

Explanation:

$v = (12 - 3t^2) m/s = ds/dt$ . . . . . . . . . . A

integrate above equation we get

$s = 12t - t^3 + C$

from information given in the question we have

t = 1 s, s = -10 m

so distance s will be

-10 = 12 - 1 + C,

C = -21

$s(t) = 12t - t^3 - 21$

we know that acceleration is given as

$a(t) = dv/dt = -6t$

[FROM EQUATION A]

Acceleration at t = 4 s, a(4) = -24 m/s^2

for the displacement from t = 0 to t = 10 s,

$s(10) - s(0) = (12*10 - 10^3 - 21) - (-21) = -880 m$

the distance the particle travels during this time period:

let v = 0,

$3t^2 = 12$

t = 2 s

Distance $= [s(2) - s(0)] + [s(2) - s(10)] = [1\times 2 - 2^3] + [(12\times 2 - 2^3) - (12\times 10 - 10^3)] = 912 m$

Compute the area and circumference of a circle given the radius r if the radius is greater than or equal to 1.0; otherwise, you

Maslowich

In this question we shall present the algorithm in pseudocode, whose structure is now summarized:

1) Inputs.

2) Algorithms.

3) Outputs.

Please notice that While-cycles consider the requirement of using the algorithm as many times as user wants.

Name: Area-or-Circunference

CHAR - decide

REAL - radius, circumference, area

Say "Do you want to calculate? [Y] - Yes/[N] - No";

Write decide;

While (decide != 'Y' and decide != 'y' and decide != 'N' and decide != 'n'):

Say "Invalid option. Do you want to calculate? [Y] - Yes/[N] - No";

Write decide;

end-While

While (decide = 'Y' or decide = 'y'):

Say "Please indicate a radius";

While (radius < 0):

Say "Radius must be equal or greater than 0. Please indicate a

radius";

Write radius;

end-While

If (radius < 1):

circumference = 2*3.14*radius;

Say "The circumference has a value of %circumference length units";

Else:

circumference = 2*3.14*radius;

area = 3.14*radius*radius;

Say "The circumference has a value of %circumference length units

and the area has a value of %area square units";

end-If

Say "Do you want to calculate? [Y] - Yes/[N] - No";

Write decide;

While (decide != 'Y' and decide != 'y' and decide != 'N' and decide !=

'n'):

Say "Invalid option. Do you want to calculate? [Y] - Yes/[N] - No";

Write decide;

end-While

If (decide = 'N' or decide = 'n'):

Say "Good luck";

end-If
