Both deal with the biology of the tissue in your mouth and the synthetic material that the tools are made of.
Answer: calculate the free fall distance and velocity without air resistance from, the free fall.
Explanation:
To find out something's speed (or velocity) after a certain amount of time, you just multiply the acceleration of gravity by the amount of time since it was let go of. So you get: velocity = -9.81 m/s^2 * time, or V = gt. The negative sign just means that the object is moving downwards
Answer:The direction the wave travels is parallel to the displacement of the medium.LW.
Electromagnetic waves are an example of this type of wave. TW
Sound waves are an example of this type of wave.LW
Ir the wave propagates in the x‑direction, the medium is also disturbed in the x‑direction. LW
If the wave propagates in the x‑direction, the medium is disturbed in the y‑ and/or z‑direction. TW
The direction the wave travels is perpendicular to the displacement of the medium.TW
Explanación:
the main difference of Transversal AND Longitudinal waves (TW AND LW) is that the disturbation direction in the media with respect to the travel direction is well different for both cases. For TW the perturbation oscilatiew perpendicular to propagation direction of the wave.
In constrant for LW the disturbation oscilates in the same direction as the wave is propagating.
The force of gravity is equal to the mass times centripetal acceleration.
Fg = m v^2 / r
The force of gravity is defined by Newton's law of universal gravitation as:
Fg = mMG / r^2
Therefore:
mMG / r^2 = m v^2 / r
MG / r = v^2
v increases as r decreases. So the planet with the smallest orbit (closest to the sun) will have the highest orbital velocity. Of the four options, that's Mercury.

Which explanations provide support for continental drift theory? Check all that apply.
Dinosaurs lived on many continents.
Coal fields match up across continents.
Tropical plant fossils were found in Arctic areas.
Similar rock types are found across continents.
Evidence of glaciers can be found in South Africa.
Coal fields match up across continents.
Similar rock types are found across continents.
Tropical plant fossils were found in Arctic areas.
Evidence of glaciers can be found in South Africa.
<h3><u>
Explanation:</u></h3>
The way the continents on the earth shifts its position is explained by the Continental drift theory. Alfred Wegener was the one who fist proposed this theory in 1912. This theory also explains how similar rocks are formed on the different continents and also the reason why some of the animal and plant fossils looks similar.
The evidences that supports the continental drift theory can be Coal fields match up across continents. Fossils of Glossopteris supports the theory of continental drift with coal fields and coastlines
. The land features, climate changes are some of the evidences that also supports the theory of continental drift.The evidences of the glaciers that can be found in South Africa also supports the explanation of the continental drift.
