Given that,
The electric field is given by,
Suppose, B is the amplitude of magnetic field vector.
We need to find the complete expression for the magnetic field vector of the wave
Using formula of magnetic field
Direction of 
vector is the direction of propagation of the wave .
Direction of magnetic field = 
We need to calculate the poynting vector
Using formula of poynting
Put the value into the formula
Hence, The poynting vector is 
Answer:
is there any pictures or diagrams that i could use to base this question off of
Explanation:
Using Fnet= ma, constant motion means 0 acceleration, Fnet ( force ) will be also 0
For contact forces to act two objects need to be touching each other in order for the force to be exerted. This force is the result of the electromagnetic repulsion between the electrons of the two objects. Field forces are not required to touch as an object placed in a the field produced by an object will have a force exerted on it. Generally the force exerted decreases with distance from the source.
Sodium and chlorine
Explanation:
The two substances found in the greatest abundance among major salts dissolved in sea water are Sodium and chlorine. These salt forms the common salt known as table salt.
- Sea water is salty because it tastes like common salt we use for cooking.
- The sodium and chlorine in table salts makes up the bulk of sea water.
- Table salt can be manufactured by evaporating sea water because it is saturated with this solute.
- Sodium chlorides combines electrovalently in sea water.
