The answer to that is D. If u think about all u have to do is multiply 5 times 2 = 10
Answer:
Part a)
F = 0.056 N
Part b)
a = 28.13 m/s/s
Explanation:
Part a)
Electrostatic force between two charged balls is given as
now we will have
r = 2 cm
now we will have
so here we have
Part b)
Now due to above force the acceleration of one ball which is released is given as
Earth has an atmosphere. which burns up small meteriods but doesn't burn up the big ones. the atmosphere also gives us weather which wears away the craters.
Answer:
Explanation:
charge of electron, e = 1.6 x 10^-19 C
V1 = 0 V
V2 = -12 V
Change in potential, ΔV = V1 - V2 = 0 - ( - 12) = 12 V
potential energy, U = q x ΔV
U = 1.6 x 10^-19 x 12
U = 1.92 x 10^-18 J
Option D,Plate Tectonics
In the rock cycle, surface events takes place at the surface of earth. Thus,
weathering and erosion are surface events, while the subsurface events he take place in the deeper section of the earth . Examples of sub surface events are plate tectonics and mountain building or anything that takes place in the inner core of earth.
