Answer:
Velocity = distance / time
if distance is same and time is 1/2
Velocity = distance / time/2
velocity = 2 (distance /time)
Velocity,= 2 * velocity
Velocity will be doubled

Matter is predominantly know to exist in three states-
-Solid
-Liquid
-Gas
The three states can be interconverted at appropriate temperature and pressure conditions. Each state exhibits unique properties which are influenced by the intermolecular forces that hold the atoms together in these states.
Ans: Thus, Every time matter changes from a liquid to a gas, the matter also experiences a change in the <u>state (or phase)</u>
Based on what you have read about wind turbines and dams, how does a generator work? A loop of ______ spins in a ______ field, producing ______ current.
Answer:
Wire
Magnetic
Electric
Explanation:
The generator works on the principle of converting mechanical energy into electrical energy.
For example in a wind turbine generator, the mechanical energy is the wind that pushes the blades of the turbine directly that leads to conversion of this it's linear motion to the rotary motion required to make rotor of the generator to spin. Finally, the harder the wind pushes, the more the mechanical energy applied and consequently, the more electrical energy can be generated.
Now, all generators work because of the effect of the magnetic field moving past an electrical coil.
Thus, the movement of a magnet across a single loop of wire produces a voltage that is induced within the wire loop as a result of the magnetic field produced by the magnet.
As a voltage is induced across the wire loop, electrons begin to flow around the loop thereby generating electric current.
