Answer:

Gravity is best described as a fundamental force.

Explanation:

Gravity is one of the 4 fundamental forces(3 of the forces out of 6).  

The description of mass is independent to Gravity. Since an objects mass determines the strength of the pull of Gravity. But it is not Gravity itself.

Molecular pull is more of a density determination. For example the pull between the atomic particles of a solid is stronger than those of a gas.

Thrust is a kind of acceleration. It is the push and resist to the drag force.

The height of the Washington Monument is measured to be 170 m on a day when its temperature is 35.0°C. What will the change in i
Alecsey [184]

Answer:

The deformation is 0.088289 m

The final height of the monument is 170-0.088289 = 169.911702 m

Explanation:

Thermal coefficient of marble varies between (5.5 - 14.1) ×10⁻⁶/K = α

So, let us take the average value

(5.5+14.1)/2 = 9.8×10⁻⁶ /K

Change in temperature = 35-(-18) = 53 K = ΔT

Original length = 170 m = L

Linear thermal expansion

\frac{\Delta L}{L} = \alpha\Delta T\\\Rightarrow \Delta L=\frac{\alpha\Delta T}{L}\\\Rightarrow \Delta L=9.8\times 10^{-6}\times 53\times 170

The deformation is 0.088289 m

The final height of the monument is 170-0.088289 = 169.911702 m (subtraction because of cooling)

Katarina [22]

Answer: Simple machine

  • The movable inclined plane is called wedge.
  • A simple machine is a machine, which contains lever and wedge, is used to push the things apart.  
  • The mechanical advantage of a wedge is given by the ratio of length of its slope to its width.
