Answer:
Because molecules are to small for us people to see with the bare eye, unless you use a telescope.
Explanation:
Current is the amount of charged passed divided by elapsed time.
I = Q/Δt
I = current, Q = charge, Δt = elapsed time
We also know an electron has a charge of 1.6×10⁻¹⁹C, so let us find the total charge by multiplying this unit of charge by the total number of electrons:
Q = 1.6×10⁻¹⁹(3×10²⁰) = 48C
We also have Δt = 6s, so let's plug these values in to solve for I:
I = 48/6
I = 8A
The answer is D) second/meter
Answer: She could research what geologists have already discovered about the canyon.
She could hike into the canyon and make observations of the rocks in each layer.
She could compare her observations of the rock layers to other rock layers in the area.
I think the answer is D: gravity
