We are going to focus on the gravitational force between Earth and our Moon. The Earth has a mass of about 6 x 10/24 kg and the
Moon has a
mass of about 7.3 x 10/22 kg. They are also currently about 4 x 10/8 meters apart.
The gravitational constant, G, is 6.67 x 10-/11 as always.
Question 1
If you were to weight yourself in the moon and the Earth, which would have the higher weight?

Answer:
Explanation:
Given:
- length of the concrete slab,
- temperature of observation,
- we've the coefficient of linear expansion for concrete,
- lower temperature limit,
- upper temperature limit,
<u>Change in length due to temperature can be given as:</u>
<u>Now at temperature 15°C:</u>
Hence the expansion crack between the slabs at this temperature must be:
Answer:
1.12 m
0.08291 m
Explanation:
u = Upstream velocity = 0.4 m/s
Re = Reynold's number = (turbulent)
= Viscosity of water =
Here the flow is turbulent so we have the relation
The approximate location downstream from the leading edge where the boundary layer becomes turbulent is 1.4 m
Boundary layer thickness relation is given by
The boundary layer thickness is 0.08291 m
