Calvin Cycle is the part of the process of photosynthesis, by which Plant makes Food (Glucose), it is independent of the light. It is essential as it is the primary source of energy on the earth

Answer:
250 kg/m3
Explanation:
The total volume of the raft is length times width times height
V = lwh = 2 * 3 * 0.5 = 3 m cubed
The volume of the raft that is submerged in water is 1/4 of total volume
3 /4 = 0.75 m cubed
Let water density = 1000 kg/m cubed and g = 10 m/s2
The buoyant force is equal to the weight of water displaced by the raft
F = 0.75 * 1000 * 10 = 7500 N
This force is balanced by the raft weight, so the weight of the raft is also 7500N
Mass of raft is 7500 / g = 7500 / 10 = 750 kg
Raft density is mass divided by volume = 750 / 3 = 250 kg/m3
This is a question about converting energy from one form to another.
<span>While it is sitting on the ledge, it isn't moving, so at that point it doesn't have any kinetic energy. What it has is gravitational potential energy due to its height above the ground. </span>
<span>Just as it lands, it's at ground level, so it doesn't have any gravitational potential energy anymore. </span>
<span>The reason is that on the way down, it sped up, so all its original gravitational potential energy was turned into kinetic energy. </span>
<span>So if you can work out how much potential energy it had to start with, you will know that that is how much kinetic energy it ended up with just before it landed. </span>
<span>potential energy = m * g * h </span>
<span>where m is the mass, g is the acceleration due to gravity and h is the height </span>
potential energy = 4.45 * 9.81 * 0.800 = 35.3 J
Hope that helps. Please give me Brainlyest answer. :]
Answer:
Explanation:
A mover carries a box across a room. A weightlifter lifts a barbell off the ground. A weightlifter holds a barbell above the head.
that what i think
The answer is B. X-rays and gamma rays. The electromagnetic spectrum consists of all types of electromagnetic radiation. The EM spectrum is arranged from the longest wavelength with the lowest frequency and lowest energy which are the radio waves and microwaves to the shortest wavelength with the highest frequency and highest energy which are the x-rays and gamma rays. Visible light that can be seen by a humans is a small portion in between the ultraviolet and infrared rays.
