Answer:
These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically; and finally, that energy flow occurs within.

2.25 amperes
Ohms law dictates that electrical voltage = current times resistance. Since you are given voltage and not the current, you will be dividing voltage by the resistance.
9.0V ÷ 4.0ohms = 2.25 amps

Answer:
I₂ = I₀ 1/4
Explanation:
For this exercise we use the definition of intensity which is the power per unit area
I = P / A
The emitted power is constant, so
P = I A
We can write this equation for the start and end point with index 2
I₀ A₀ = I₂ A₂
I₂ = I₀ A₀ / A₂
The spot area is the area of the circle
A₀ = π r₀²
We substitute
I₂ = I₀ r₀² / r₂²
It indicates that the radius of the spot is twice the initial radius
r₂ = 2 r₀
I₂ = I₀ (r₀ / 2 r₀)²
I₂ = I₀ 1/4
Answer:
A 26m
Explanation:
firstly the answer will not be part c as distance unit will be meters (m)
next, substitute the values of a and t as shown
the answer rounded off to 2 significant figures will be hence 26m
They both use messenger particles to carry the force. Gluons for the strong force and W and Z for the weak. And both sets of particles solely with the sub atomic particles of the nuclei: quarks and neutrinos. That is, their range is limited to the nuclei of the atoms and the ions.
