An airplane is traveling at a fixed altitude with an outside wind factor. The airplane is headed N 40° W at a speed of 600 miles per hour. As the airplane comes to a certain point, it comes across a wind in the direction N 45° E with a velocity of 80 miles per hour. What are the resultant speed and direction of the airplane? Round your answers to the nearest hundredth.

Explanation:

Given

Plane is initially flying with velocity of magnitude

at angle of with North towards west

Velocity of plane airplane can be written as

Now wind is encountered with speed of at angle of

resultant velocity

for direction

west of North

no

sodium is solid at rt

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
