Carbon is pulled from the atmosphere in the carbon cycle through the process of photosynthesis. Details about photosynthesis can be found below.
<h3>What is photosynthesis?</h3>
Photosynthesis is the process whereby green plants obtain their nutrition by utilizing energy from sunlight.
Green plants absorb carbon in the form of carbon dioxide from the atmosphere and use it in the photosynthetic process.
This means that one way that carbon is removed from the atmosphere during the carbon cycle is through photosynthesis.

Answer:
50 degrees
Explanation:
Usually in physics in solving such questions refractive index of air is taken as 1.00 (n=1.00) by assuming that air is a vacuum. Hence, the light ray passes from water to air at an angle of incident of 40 degrees, it means that it has angle of 50 degrees to the normal line.
Answer:
B.)Angular momentum is always conserved
Explanation:
Angular momentum is given by:
where
m is the mass of the object
v is its speed
r is the distance between the object and the centre of its circular trajectory
In absence of external torques, angular momentum is always conserved. That means that for the spinning star, if its radius r decreases (because it shrinks), in order for L (the angular momentum) to be conserved, the speed (v) must increases, therefore the spinning star speeds up.
So, the correct choice is
B.)Angular momentum is always conserved
From 50km/h to 0km/h in 0.5s we need next acceleration:
First we convert km/h in m/s:
50km/h = 50*1000/3600=13.8888 m/s
a = v/t = 13.88888/0.5 = 27.77777 m/s^2
Now we use Newton's law:
F=m*a
F=1700*27.7777 = 47222N
Answer:
a. The magnitude of the magnetic field is changing.
b. The magnetic field is changing direction with respect to the bracelet.
c. The bracelet is moving in the magnetic field.
Explanation:
Magnetic flux is a measure of the total magnetic field that passes through a given area. The value of the flux depends on the magnitude of the magnetic field, the area it crosses and its orientation relative to the magnetic field. Therefore, all three reasons are valid.
