Light with a wavelength of x is incident on a metal. What would happen if the light's wavelength was changed to 4x? A.
Nothing would change.
B.
More electrons would be ejected.
C.
The ejected electrons would have more kinetic energy.
D.
The result would depend on the metal's threshold frequency.

im guessing its B

Explanation:

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
