1. Mount Kilimanjaro, 19,341 feet
2. Mount Kenya, 17,057 feet
Depends, what are the lengths given?
it might be c. this one is actually confusing. i am sorry that i couldn't help that much.
hope you get the answer you need.
I think there is a mistake in the subject area. This has nothing to do with geography, but with physics. This topic is about the linear expansion of conductive materials when heated to a higher temperature. The equation for linear expansion is
ΔL = L0*α*ΔT, where
ΔL is the change in length when heated
L0 is the original length of the rod
α is the coefficient of linear expansion; this is an empirical data for a specific kind of material
ΔT is the change in temperature
Since ΔL is same for lead and quartz, we can equate them.
L0,lead*α,lead*ΔT = L0,quartz*α,quartz*ΔT
The α for lead is 29×10^6 °C/m while the α for quartz is 14×10^6 °C/m. Since ΔT are the same for both materials, ΔT will be cancelled out. Therefore, the equation for L0,quartz is:
L0,quartz = (L0,lead*α,lead)/α,quartz
L0,quartz = (0.10 m*29×10^6 °C/m)/14×10^6 °C/m
L0,quartz = 0.207 m
The distances between planets will vary depending on where each planet is in its orbit around the Sun. Sometimes the distances will be closer and other times they will be farther away.
The reason for this is that the planets have elliptical orbits and none of them are perfect circles. As an example, the distance between the planet Mercury and Earth can range from 77 million km at the closest point, to as far as 222 million km at the farthest. There is a huge amount of different in the distances between the planets depending on their position on their orbit path
