A 77 ton monolith is transported on a causeway that is 3500 ft long and has a slope of about 3.6 degrees. How much force paralle
const2013 [10]

Answer:

4.8 ton

Explanation:

We are given that

Mass,m=77 ton

Displacement,s=3500 ft

\theta=3.6^{\circ}

We have to find the force parallel to the incline would be required to hold the monolith on this causeway.

The force parallel to the incline would be required to hold the monolith on this causeway=Fsin\theta

Using the formula

The force parallel to the incline would be required to hold the monolith on this causeway=77sin3.6=4.8 Ton

At what water depth will a deep-water wave with a wavelength of 40 meters begin to "feel bottom"? 5 meters 15 meters 20 meters 1
ella [17]
The answer is 20 meters would be the water depth started to feel bottom. This is half of the wavelength. The reason behind this is the wave travels half or the partial of the wavelength underneath the surface. For that reason that is where the wave would be starting to feel the ground.
