Frequency because all the other things may have to do with energy but frequency is the one that has to do with number of wavelength passed by a certain point or a certain time
They would have the magnetic parts of the rocks oriented differently. This leaves a trace that allow scientists to find out how often this actually happens (as far as I remember, it's on average once in 800 000 years)
Options:
a) 10 m/s²
b) 8 m/s²
c) 4.4 m/s²
d) More information is needed
Answer:
d) More information is needed
Explanation:
The acceleration due to gravity at an altitude h above the surface of a planet is given by the equation:
.................(1)
where the altitude above the surface of the planet X, h = 3000 km
Acceleration due to gravity at the surface of the planet, g₀ = 10 m/s²
To be able to get the acceleration due to gravity, g, at an altitude h above the surface of the planet, all parameters must be substituted into equation (1).
Unfortunately, the radius, R, of the planet, X, is not given. This means that there are no sufficient parameters(information) to find the acceleration due to gravity at an altitude h above the surface of the planet.
