Into molecules of

oxygen.
The complete reaction of the photosynthesis is in fact:
and the energy of the light coming from the sun is also used to make the reaction possible.
We can solve both parts of the problem by using the lens equation:
where
f is the focal length
is the distance of the object from the lens
is the distance of the image from the lens
Let's also keep in mind that for a converging lens, the focal length is taken as positive, so f=+19.0 cm.
(a) In this case,
. So, the lens equation becomes
And so the distance of the image from the lens is
where the positive sign means the image is real, i.e. is located behind the lens (opposite side of the real object)
(b) In this case,
. So, the lens equation becomes
And so the distance of the image from the lens is
where the negative sign means the image is virtual, i.e. is located in front of the lens (i.e. on the same side of the real object)
Answer: D
Explanation: B and C are irrelevant in this context, there is no reason to consider them. The answer is D as if the ball pushes the bat left, the bat pushes back on it in the opposite direction (to the right)
Momentum is always conserves in a collision, so 2460*130 + 1225*89 = total momentum. After the collision, you can treat the two vehicles as one mass and divide momentum by mass to obtain velocity. 428825/3685 = 116.37 km/hr. Closest answer is B
