Elecromagnetic waves can travel through a vacuum, but a mechanical wave cannot.
Mechanical waves can only exist in a medium, such as air or water. Electromagnetic
waves behave like waves and particles, but mechanical waves only behave
like waves. </span>
Answer:
"Magnitude of a vector can be zero only if all components of a vector are zero."
Explanation:
"The magnitude of a vector can be smaller than length of one of its components."
Wrong, the magnitude of a vector is at least equal to the length of a component. This is because of the Pythagoras theorem. It can never be smaller.
"Magnitude of a vector is positive if it is directed in +x and negative if is is directed in -X direction."
False. Magnitude of a vector is always positive.
"Magnitude of a vector can be zero if only one of components is zero."
Wrong. For the magnitude of a vector to be zero, all components must be zero.
"If vector A has bigger component along x direction than vector B, it immediately means, the vector A has bigger magnitude than vector B."
Wrong. The magnitude of a vector depends on all components, not only the X component.
"Magnitude of a vector can be zero only if all components of a vector are zero."
True.
The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere.
The stratosphere is stratified in temperature, with warmer layers higher and cooler layers closer to the Earth; this increase of temperature with altitude is a result of the absorption of the Sun's ultraviolet radiation by the ozone layer.
This is in contrast to the troposphere, near the Earth's surface, where temperature decreases with altitude.
The border between the troposphere and stratosphere, the tropopause, marks where this temperature inversion begins. Near the equator, the stratosphere starts at as high as 20 km around 10 km at mid altitudes, and at about 7 km at the poles.
Stratospheric temperatures also vary within the stratosphere as the seasons change, reaching particularly low temperatures in the polar night. Winds in the stratosphere can far exceed those in the troposphere, reaching near 60 m/s in the Southern polar vortex.
So the correct answer for the above is
c. is where most weather occurs
