What kind of rays are produced when a metal, such as tungsten, is bombarded with electrons moving with very high velocities?
a. x-rays
b. gamma rays
c. cathode rays
d. infrared rays

x-rays

Explanation: When the electrons from the filament strike the tungsten target, x-rays are created photons are created if they either hit a target nucleus directly (rare) or their path takes them close to the nucleus. If a high- speed electron hits the nucleus of a target atom, all its kinetic energy is transformed into a single x-ray photon.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
