The graph below represents a wave that takes 5 seconds to pass by: A (2 pts) Identify the following values:

i. Amplitude:

ii. Wavelength:

ii. Frequency:

iv. What type of wave is this?

B. (1 pt) Calculate wave speed. Show all work for full credit

(1 pt) Explain how the wave speed will change if the amplitude increases to C 0.40 m.

D. (1 pt) Assuming the wave maintains the same speed, if the wavelength were to increase to 6m, explain the effect on the frequency?​

i believe it is b. what was the cause of the big bang

hope this !

the higher the current the higher the mag field around it the higher the influence on the compass

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

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
