Answer:
"332.8 m/s" is the right solution.
Explanation:
The given values are:
Wavelength,

Frequency,

As we know,
⇒ 
or,
⇒ 
By putting the given values in the above relation, we get
⇒ 
⇒ 
let the plane is flying at some angle theta with west towards north
Now we can use the components


now since plane has to fly towards west so net speed in north must be equal to speed in south for air
So we can say



so plane has to fly in direction 14.5 degree North of west
Insulators does not allow flow of electric charges at all.
bad conductors are those which can conduct electricity but offers more opposition (resistence) to the flow of current compared to the flow of current in a good conductor.
all dielectrics are insulators, but all insulators are not dielectric.
hope this help
Answer:
E = 4156.02 Vm⁻¹
Explanation:
The magnitude of the uniform electric field between the plates can be given by the following formula:

where,
E = Electric field strength = ?
ΔV = Potetial Difference = 293 V
d = distance between plates = 7.05 cm = 0.0705 m
Therefore,

<u>E = 4156.02 Vm⁻¹</u>
