Causes of a severe storm are:
High winds
wildfires
hail
A severe thunderstorm includes winds of 58 MPH or greater
A. Transverse wave. This is because it’s not either of the other two
Answer:
Pressure
Surface
Flow
Fluency
Explanation:
*Surface
The surface tension is the force with which the surface molecules of a liquid are attracted to bring them inside and thus decrease the surface area.
*Flow
It is defined as resistance to flow. The viscosity of a liquid depends on the intermolecular forces:
-The higher the intermolecular forces of a liquid, its molecules have a greater difficulty moving between them, therefore the substance is more viscous.
-Liquids that are made up of long, flexible molecules that can bend and tangle with each other are more viscous.
* Pressure
if the molecules of the liquid have a greater intensity of intermolecular force, then they will be trapped in the liquid and will have less facility to pass into the gas phase.
on the contrary to lower intensity of intermolecular force, then the molecules can escape more easily to the gaseous state.
*Fluency
This property allows liquids to easily pass through a hole regardless of size, as long as this hole is at a lower or the same level of the container where the liquid is stored.
This property indicates the deformability of a liquid which is very wide without requiring mechanical stress.
Answer: DC Current
Explanation:
Battery is a source of constant potential difference and it will create a constant voltage across any conductor
due to this constant voltage difference the current in this conductor will remain constant
So here since the voltage across the conductor is constant so we can say that current in the conductor will remain constant and hence this is known as DC current.
While for variable current in direction and magnitude is to be obtained only when the conductor is connected with AC voltage source as we know that AC voltage is variable with magnitude and direction both
A battery is the power source for DC type of current. A battery is a source of constant potential difference that produces a constant current unlike in AC source where the voltage and hence the current changes its polarity continuously.Hence, the current produced by battery is direct current and not Alternating current.
Hope this helps........ Stay safe and have a Merry Christmas!!!!!! :D
