Answer:
The power in this flow is
Explanation:
Given that,
Distance = 221 m
Power output = 680 MW
Height =150 m
Average flow rate = 650 m³/s
Suppose we need to calculate the power in this flow in watt
We need to calculate the pressure
Using formula of pressure
Where, = density
h = height
g = acceleration due to gravity
Put the value into the formula
We need to calculate the power
Using formula of power
Put the value into the formula
Hence, The power in this flow is
Answer:
Explanation:
m = Mass of water = 2 kg
c = Specific heat of water =
= Change in temperature =
Change in thermal energy is given by
Cale's change in thermal energy was .
(a) -1.208 m
The position of the particle at time t is given by
where:
is the initial position
is the initial velocity
is the acceleration
Substituting into the equation t=3.70 s, we find the position after 3.70 seconds:
(b) -0.838 m/s
The velocity of the particle at time t is given by:
where
is the initial velocity
is the acceleration
Substituting t = 3.70 s, we find the velocity after 3.70 seconds:
<h3><u>Answer;</u></h3>
Smooth muscles
<h3><u>Explanation</u>;</h3>
- Smooth muscles are the muscles that cause blood vessels to dilate and constrict. Smooth muscles forms the supporting tissues of the blood vessels and hollow internal organs such as intestines, bladder, etc.
- Hormones such as vasopressin and Norepinephrine trigger the contraction of smooth muscles and thus constricting the blood vessels.
- When these hormones production is stopped then the smooth muscles will relax and thus dilating the blood vessels.
