Answer:
810.94 m/s
Explanation:
Applying,
v = √(2gR)............. Equation 1
Where v = escape velocity of the spherical asteroid, g = acceleration due to gravity, R = radius of the earth
From the question,
Given: g = 0.636 m/s², R = 517 km = 517000 m
Substitute these values into equation 1
v = √(2×0.636×517000)
v = √(657624)
v = 810.94 m/s
Hence, the escape velocity is 810.94 m/s
Geothermal power plants use the renewable resource of heat from within the Earth to generate electricity.
Explanation:
The correct statement is that geothermal power plants use the renewable resource of heat from within the Earth to generate electricity.
Geothermal energy is heat energy from within the earth.
- Geothermal energy is not available everywhere on the earth. It is restricted to certain geologic terrains.
- It is a renewable source of energy whose usage cannot be depleted at our current rate of consumption.
- This heat is used to produce electricity in areas where they occur.

Answer:
Be sure you understand two optics principles: the focal length of a convex mirror is NEGATIVE (by convention) and R / 2 = f.
Find f, take its negative, plug in the mirror equation and obtain Di = - 24 cm. This indicates that the image is virtual (as it should be in a convex mirror), is erect (as all virtual images are), is diminished (as it should be) and INSIDE the mirror as it should be.
Explanation:
We know average speed =total distance/time taken
So avg speed=(85+63)/(5+5)=14.8km/hr
Answer: A
Reason: one of his contributions was the development of a hierarchical system of classification of nature. Linnaeus also provided us with a consistent way to name species called binomial nomenclature. (From Internet)
