How much below the surface of earth does the acceleration due to gravity reduces to 36%?
Since, the acceleration due to gravity decreases by 36% of its value on the surface of the earth.
How much below the surface of the earth does the acceleration due to gravity become 10?
Answer Expert Verified Let the depth at which acceleration due to gravity ( g) becomes 70% or 7g/10 = d. d= 1920 km.
How does the value of acceleration due to gravity vary with height?
The acceleration of an object changes with altitude. The change in gravitational acceleration with distance from the centre of Earth follows an inverse-square law. This means that gravitational acceleration is inversely proportional to the square of the distance from the centre of Earth.
At what height above the earth’s surface the value of g is same as in a mine?
Answer Expert Verified ⇒ h = 40 Km (Ans.)
At what height above Earth’s surface is the value of g decreases by 2?
Answer (2) Acceleration due to gravity above the surface of earth at a height h is given 2 ‘ 1 ⎛ ⎞ ⎜ ⎟ ⎝ ⎠ e h g g R here, g ‘ = 0.98 g 2 0.98 1 e h R 2 0.02 e h R h = 0.01 R = 0.01 × 6400 km = 64 km 17.
At what depth is the value of G same as at a height of 40km from the surface of earth?
We know that d=2h so 2*40=d therefore d=80km where value of g is same as that on the height 40km.
What depth is below the surface of water?
Answer. Pressure under water is given by the sum of atmospheric pressure and pressure of fluid. Thus, depth in water at which pressure will be equal to twice the atmospheric pressure is 10.2 m.
At what depth below the ocean surface is the pressure equal to two atmospheres?
33 feet deep
What is the deepest spot in the oceans?
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 36,200 feet deep.
