Answer:
The maximum value of the magnetic field in the given wave is 6.67 nT.
Explanation:
Given;
maximum value of the electric field, E₀ = 2.0 V/m
The maximum value of the magnetic field in the given wave is calculated as;
where;
c is the speed of light = 3 x 10⁸ m/s
Therefore, the maximum value of the magnetic field in the given wave is 6.67 nT.
Answer:
mass and speed determine object's kinetic energy
potential energy is the energy of position
the more mass and height the more potential energy it has

Insulators do not allow electrons to move easily through them.
Resistance of a wire is directly proportional to its length and inversely proportional to the square of its radius.
Thus, if the length is doubled, and the radius is halved:
R₂ = 2R₁/(1/2)²
R₂ = 8R₁
Therefore the resistance increases eight times.
