Answer:
image is 14.47 cm behind the lens
height is 2.11 mm
Explanation:
Given data
h = 2.03 cm
p = 1.39 m = 139 cm
focal-length f = 131 mm = 13.1 cm
to find out
Where is the image and How high is it
solution
we know focal length formula that is
1/f = 1/p + 1/q
put here value to find q
1/ 13.1 = 1/ 139 + 1 solbe/ q
q = 14.463066 cm
so image is 14.47 cm behind the lens
and
height is calculate
height / h = - q / p
put here all value
height = -14.47 / 139 × 2.03
height = −0.211324 cm
here -ve sign show image is inverted
so height is 2.11 mm
Answer:
x₂ = x₁ + v₁t + at²/2
Explanation:
Right out of the textbook.
Force = mass x acceleration
25N = 0.40kg x acceleration
25N/0.40kg = acceleration
acceleration = 62.5 N/kg
N/kg is the equivalent of m/s²
So your acceleration is 62.5 meters per second squared
Answer:
Fossil fuels release carbon dioxide into the atmosphere. Natural gas is the best fossil fuel in terms of energy output per unit of carbon dioxide emitted. Biomass is renewable because a new crop can be grown after each harvest, and biomass is a low carbon fuel. Biomass has the approximate chemical formula CHO.
