Gamma rays are the highest energy EM radiation and typically have energies greater than 100 keV, frequencies greater than 1019 Hz, and wavelengths less than 10 picometers.
<span>Birds which famous for performing a ritualized mating dance are: The Grebes
Grebes most commonly live near a fresh water source.
They conducted this ritual because When two Grebes with opposite sex dances near each other, they will release some sort of pheromones that make them attracted to one another. </span>
Pretty sure physical, a chemical change would be something of the time of acid rain, meanwhile physical changes are the ones that affect the form not the actual chemical composition
Answer:
magnitude of net magnetic field at given point is
Explanation:
As we know that magnetic field due to a long current carrying wire is given as
here we we will find the magnetic field due to wire which is along x axis is given as
r = 2 m
now we have
into the plane
Now similarly magnetic field due to another wire which is perpendicular to xy plane is given as
r = 2 m
now we have
along + x direction
Since the two magnetic field is perpendicular to each other
So here net magnetic field is given as
