The correct answer is rock cycle
<span>Earth's rotation is the rotation of the planet Earth around its own axis. The Earth rotates from the west towards east. As viewed from North Star or polestar Polaris, the Earth turns counter-clockwise.</span>
Off the top of my head, I only know 9 and 11, so I'll answer those two.
9) A heterotroph is an organism that relies on other organisms for food/energy
An autotroph can produce its own food from inorganic compounds (light)
11) Vascular plants have specialized tubes for transporting nutrients
Nonvascular plants do not have such tubes and are simpler
D) because the refrigerator was much heavier than the other objects
The equation for electric potential of a point charge is:
V=(k*q)/r where k=9*10^11 N m²/C², q is the charge and r is the distance from the charge to the point in which we are calculating the potential.
q=-5.2*10^-6 C
r=12 cm = 0.12 m
Now we plug in the numbers and get:
V=-3.9*10^5 Volts, so the correct answer is the second one.
