<span>In order to find the value of "a" and "b", first of all perform the multiplication in the parenthesis.
Thus
(3.5x1016) = 3556
and
(2.2x1010) = 2222
As per question;
(3556)x(2222) = 10 axb
By dividing both sides by "10"
we get
(3556)x(222.2) = axb
or
(355.6)x(2222) = axb
by comparing both sides of the equation,
we get that a = 3556 and b = 222.2
or
a = 355.6 and b = 2222

Answer:
Sympathetic nervous system
Explanation:
The sympathetic nervous system of the autonomic division prepares the body for stress or emergency conditions by generating the “fight-or-flight” responses. The sympathetic nervous system triggers the release of stress hormones from the adrenal medulla to generate the set of physiological responses.
There is dilation of the pupil, and an increased rate of heartbeat and increased blood pressure. Other responses include dilation of airways and dilation of blood vessels that supply blood to skeletal muscles, heart muscles, liver, etc. Under the given emergency condition, the sympathetic nervous system of Meghan was activated to generate the fight or flight response.
Potential gravitational energy is computed with the formula:
Where:
PEgrav = Potential gravitation energy (J)
m = mass (kg)
h = height (m)
g = acceleration due to gravity (9.8m/s^2)
Take note that acceleration due to gravity is a constant.
All you need to do is put in what you know and solve for what you don't know. So your given is the following:
PEgrav = 3,528J
m = 24 kg
g = 9.8 m/s^2
Put that into your formula:
The height of the cliff is 15m.
During the day, due to the presence of sunlight, the process of photosynthesis peaks over that of respiration. Photosynthesis uses carbon dioxide to make carbohydrates releasing oxygen as a byproduct. During the night, because there is no sunlight, the rate of photosynthesis drops. This, therefore, causes the rate of respiration to surpasses the rate of photosynthesis. In respiration, oxygen is consumed and carbon dioxide is released.
