At the instant the second bulb is connected ...
... the brightness of the <u>first bulb</u> doesn't change
... the brightness of the <u>second bulb</u> changes from dark (no brightness) to equal to the first bulb
Answer:
The answer to your question is: d = 0 m, it does not move
Explanation:
Data
vo = 20 m/s
a = -1 m/s2
t = 40 s
d = ?
Formula
d = vot + (1/2)at²
Substitution
d = (20)(40) + (1/2)(-1)(40)²
d = 800 - 800
d = 0 m It suggest that it does not move.
I hope it can help you
Answer:
1440 N
Explanation:
The electrostatic force between the two charges is given by:
where:
is the Coulomb's constant
is the value of each charge
r = 20.0 cm = 0.20 m is the separation between the charges
Substituting numbers into the equation, we find
The correct option is
a. Acetyl-CoA combines with a pyruvic acid to make glucose in the Krebs cycle.
Explanation:
The Krebs citric acid cycle happens within the mitochondrial matrix and generates a pool of energy (ATP, NADH, and FADH2) from the oxidization of pyruvate, the tip product of metabolism. Pyruvate is transported into the mitochondria and loses dioxide to make acetyl-CoA, a 2-carbon molecule.
Back then, Robert Hooke found cells from a cork and named it cells. Later on, Matthias Schleiden found cells from plant parts and concluded that all plants are made of cells. Theodor Schwann, after observing many different animal cells, concluded that all animal have cells. Several years later, Rudolf Virchow hypothesized that cells divide to form new cells. Virchow proposed that every living organism has cells. His observations and conclusions and those of others are summarized in the cell theory
