Answer:
greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range
Explanation:
Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
Answer:
a) i = -9.63 cm
, h ’= .0.24075 cm erect
b) i = 259.74 cm
,
Explanation:
For this exercise let's start by finding the focal length of the lens
1 / f = (n-1) (1 / R₁ - 1 / R₂)
1 / f = (1.70 -1)) 1 / ∞ - 1/13)
1 / f = 0.0538
f = - 18.57 cm
Now we can use the constructor equation
1 / f = 1 / o + 1 / i
1 / i = 1 / f - 1 / o
1 / i = -1 / 18.57 -1/20
1 / i = -0.1038 cm
I = -9.63 cm
For the height of the
image let's use magnification
m = h '/ h = - i / o
h ’= -h i / o
h ’= - 0.5 (-9.63) / 20
h ’= .0.24075 cm
b) we invert the lens
The focal length is
1 / f = (1.70 -1) (1/13 - 1 / int)
1 / f = 0.0538
f = 18.57 cm
1 / i = 1 / f -1 / o
1 / I = 1 / 18.57 - 1/20
1 / I = 3.85 10-3
i = 259.74 cm
h ’= - 0.5 259.74 / 20
h ’= 6.4935 cm
Based on data from world energy consumption, the estimated humanity’s current consumption of energy in one day is above 208 million joules per day.
<h3>What is energy consumption?</h3>
Energy is the ability to do work. Therefore, energy consumption refers to the amount of energy used to do work.
Humans need energy for various purposes such as;
- lighting
- heating
- operation of machines
- feeding, etc.
Due to rapid growth on population as well as technology, the human energy consumption is on the increase.
In 2020, the world primary energy consumption was 71,4 GJ per person for a world population of about 7.7 billion people.
Therefore, the estimated humanity’s current consumption of energy in one day is above 208 million joules per day.
