2. Discuss the relationship between electric and magnetic fields.

Using the equation T=2π√L/g solve for L

Two slits 0.200 mm apart. Light of wavelength 488 nm impinges on the slits and the interference pattern is observed on a surface 1.00 m from the slits. How far from the central axis is the fourth maxima? (9.8 mm)

5. The name for the thick, insulated cables used for jump starting a car is A. alligator cables B. jumper cables C. ignition cables D. terminal cables

How long does light take to travel from the sun to earth? heres the exact question: light travels at 300,000 km. s. The sun is a total of 148 million kilometres from the earth. How long does it take light to travel from the sun to the earth

Which of the following describes an ectomorph body type? Broad, muscular, and may have difficulty losing weight Long, slender, and may have difficulty gaining weight Short, overweight, and may have difficulty losing weight Tall, strong, and easily

What element will form an ionic bond with carbon

State the condition for maximum current to be drawn from the cell

Anti-reflective coatings on lenses use thin-film interference to eliminate the reflection of a particular color. Suppose a glass lens (ng = 1.53) is covered with a thin film (nf = 1.31) to prevent green light (λ = 534 nm) from being reflected.

Light incident on a surface at an angle of 45 degrees undergoes diffused reflection. At what angle will it reflect?

A ship on the surface of the ocean receives a sonar echo back from an underwater object. The echo path from the object to the ship is at an angle of 35 degrees above the horizontal and takes 3s to return. (Velocity of sound in sea water = 1500m/s).
