Answer:
h = 30.61 m
Explanation:
In this problem they indicate the pressure at the bottom of the lake and the density of the water, for which they must ask what is the depth of the lake.
The pressure is given by the expression
P = 
+ rho g h
P - P_{atm} = rho g h
The gauge pressure value is P- P_{atm} = 3 105 N / m²
h = 
let's calculate
h = 
h = 30.61 m
Answer:
The leaf cells would be unable to convert the sun's energy to make food.
Explanation:
The chloroplast in the leaf are used to make food for the plant. If the leaf loses its chloroplast, the leaf with not be able to use solar energy to manufacture their food.
- During photosynthesis, green plants manufacture their food.
- They use sunlight to cause a reaction between carbon dioxide and water.
- The sunlight is trapped using chlorophyll present in the leaf.
- In the absence of the chlorophyll contained in the chloroplast, no solar energy would be generated to cause the reaction to take place.
As we know that P=IV so P = (0.5A)(4.5V)
P= 2.25 watt
I dont know the answer i just want brainy points<span />
Answer:
λ = 1.388 x 10⁻⁶ m = 1388 nm
Explanation:
We can use the Young's Double Slit experiment formula here to solve this numerical:
where,
λ = wavelength = ?
Δx = distance between adjacent bright fringes = 1.62 cm = 0.0162 m
d = slit separation = 0.24 mm = 0.00024 m
L = distance from screen to slits = 2.8 m
Therefore,
<u>λ = 1.388 x 10⁻⁶ m = 1388 nm</u>
