Answer:
Mechanical waves are defined by which of the following?
C. All of the above
Since, mechanical waves are created when an energy source vibrates, and they carry energy from one place to another through a medium, this is the right option.
Mechanical waves need an energy source to produce them?
True because a mechanical wave needs an initial energy input.
A wave has a wavelength of 100 mm and a frequency of 6 Hz. What is its speed?
600 mm/s
Wave speed = wavelength X frequency
Wave speed = 100 X 6
Wave speed = 600 mm/s
Amplitude of a wave is?
B. How high the wave is from resting point
By definition of amplitude.
Answer:
MISSING DATA, SPEED AT WHICH IT WAS LAUNCHED OR INITIAL
DISTANCE THAT REACHED UPWARDS

The formation ice sheets cause the Earth's surface to sink so much that when the ice melts, the crust and mantle does not rebound.
Explanation:
The above-mentioned statement is the only false statement
During the Ice ages, large continental parts were covered under thick ice sheets. This imposed a superincumbent additional load on the Earth's crust.
Isostasy refers to the balance that exists between parts of Earth's mantle and crust. Isostatic adjustments are a common phenomenon. As a result of isostatic adjustments, several parts of the world have risen by as much as 900 feet as an adjustment to superincumbent load since ice ages. E.g. Parts of Scandinavian countries have witnessed these activities and also undergoing this process.

See Explanation
Explanation:
The density of a substance is an intrinsic property. Intrinsic properties are properties that are characteristic of a material. It does not depend on the amount of substance present.
Since density is an intrinsic or intensive property, If you cut a piece of gold in half, the density of each piece will still be 19.32 g/cm 3 because density does not depend on the size of the gold piece.
Answer:
the value of x is 3.7 because they are arranged in a particular manner.
