The largest reservoir of the Earth's carbon is located in the deep-ocean, with 36,000 billion tons of carbon stored, whereas approximately 65,500 billion tons are found on Earth combined.
This is by far the largest reservoir, carbon dioxide is stored in the interior of the earth in the form of carbonate rocks, such as limestone, dolomites, and chalk.
Answer:
The shear modulus of the polymer is 5 MPa
Solution:
As per the question:
displacement of the top plate, d = 2 mm = 0.002 m
Horizontal Force, P = 2 kN = 2000 N
Width of the block, w = 100 mm = 0.1 m
By small angle analysis:
Angle,
Now,
Stress, =
Answer:
42.9 cm
Explanation:
given,
speed of sound, v = 340 m/s
Frequency of tuning fork, f = 198 Hz
The length of the shortest air column closed at one end.
this is the case of the standing wave.
L = N λ
N = the number of complete sine waves in the standing wave.
The standing wave in the problem is the first harmonic of a pipe open at one end.
N = 1/4
we know,
v = f λ
340 = 198 x λ
λ = 1.717 m
now,
L = N λ
L = 42.9 cm
minimum length of the required pipe is 42.9 cm.
Answer: The electric repulsion between the two protons is stronger than the gravitational attraction.
Explanation: Please see the attachments below
<span>From formula we get
redius^3 = (period^2*(mass of Mars)*(Gravitational acceleration)))/4*pi^2
From Into this equation put period = 8.86 * 10^4 sec, mass of mars = 6.39*10^23 kg ,Gravitational acceleration= 6.67*10^-11 and pi = 22/7 and get value of r
which is 2.7 * 10^7 meters</span>
