Two particles are separated by 0.38 m and have charges of -6.25 x 10-9C and 2.91 x 10-°C. Use Coulomb's law to predict the force between the
particles if the distance is doubled. The equation for Coulomb's law is
F kanga, and the constant, k, equals 9.00 x 109 Nm2/C2.
A. -2.83 x 10-7N
B. 2.83 x 10-7 N
C. -1.13 x 10-6N
O D. 1.13 x 10-6N

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.

c. resource depletion
