1) 4°C : It has the highest density as shown on the graph.
2) Water expands when it freezes, making it less dense than just water.
3) The ice would sink to the bottom, then the rest of the water would freeze as well, the entire lake/river/whatever will freeze eliminating the organisms that live there.
Answer:
a)
m/s
b)
Angular frequency = 
Explanation:
As we know
q is the charge on the electron = 
C
B is the magnetic field in Tesla = 
T
r is the radius of the circle = 
m
mass of the electrons = 
Kg
a)
Substituting the given values in above equation, we get -
m/s
b)
Angular frequency =
The type of energy that depends on position is called
kinetic energy
from shortest wavelength to longest:
Ultraviolet
visible
infrared
microwave
so the answer is B
Answer:
cross at many points
Explanation:
According to the diagram it does not shows the real electric field as the electric field does not intersect with each other but according to the given diagram many lines are intersected with each other
So the correct option is C as it would be crossed at many points
Hence, the same would be relevant
