I would say mountain. As the volcanic lava and Ash builds up. The eventually forms a mountain. There are many volcanic mountains in the world, like mount. Everest.
F = G m1*m2 / r^2 => [G] = [F]*[r]^2 /([m1]*[m2]) = N * m^2 / kg^2
That is one answer.
Also, you can use the fact that N = kg*m/s^2
[G] = kg * m / s^2 * m^2 / kg^2 = m^3 /(s^2 * kg)
Answer:
3
Explanation:
Because the pressure in the air, it’s causes particles to move farther apart from each other.
There are several information's already given in the question. Let us write them down first.
Radius of the tank = 3 feet
Height of the tank = 10 feet
Value of pi = 3.14
Then
Volume of the cylindrical tank = 3.14 * (3)^2 * 10
= 3.14 * 9 * 10
= 282.6 ft^3
Now
Heating capacity of 1 cubic foot of natural gas = 1030 BTU's
Then
Heating capacity of 282.6 cubic foot of natural gas = 1030 * 282.6
= 291078 BTU's
I hope the procedure is clear enough for you to understand.
Work done in moving a proton = potential difference×Charge of a proton
= 164×1.6×10⁻¹⁹ = 2.624×10⁻¹⁷ J
This work done should be equal to change in kinetic energy.
Initial speed of proton is zero therefore K.E initial will be zero.
Work done = final kinetic energy = 2.624×10⁻¹⁷ J
K.E = mv²/2
v² = 2(2.624×10⁻¹⁷)/1.6×10⁻²⁷ = 3.28×10¹⁰ m/s
∴ v = 1.811×10⁵ m/s
