A) ATP and NADPH
B) ATP and ADP
C) NADP+ and ADP
D) NADPH and NADP+
Answer:
The answer choice is: A) ATP and NADPH
Explanation:
Your question is asking the components that are created during light - dependent reaction, and then used in independent reaction. That would be shown in the photo below!
ATP and NADPH is created from light dependent then transfered and transformed into different components from the calvin cycle (light independent cycle)
Two compounds are produced during the light-dependent reaction then used in the light-independent reaction - A) ATP and NADPH
Photosynthesis is a process that takes place in the Chloroplast of plant cells. Autotrophs obtain their energy source (food) in the presence of sunlight.
The photosynthesis process occurs in two distinct stages; light-dependent reaction and light-independent reactions.
the light reactions take place in the thylakoid membranes of chloroplasts.The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesisThese molecules are the energy storage molecule ATP and the reduced electron carrier NADPH.Thus, two compounds are produced during the light-dependent reaction then used in the light-independent reaction - A) ATP and NADPH

How can you find the frequency or period of ocean waves?
Answer: As you probably have seen in the ocean or a lake, the stronger the wind, the higher the waves. The period and wavelength can be expressed in terms of their reciprocals, the wave frequency ω = 2(pi)/T, and the wave number κ = 2(pi)/λ.
Explanation: To find the period, we solve for T=1f, given the value of the frequency (f=2s−1). T=12 s−1=0. 5 s. Since one definition of wavelength is the distance a wave has traveled after one complete cycle (or one period), the values for the wavelength (λ=0.9m) as well as the frequency are given.

A runner is jogging in a straight line at a
steady vr= 8.4 km/hr. When the runner is
L= 6.3 km from the finish line, a bird begins
flying straight from the runner to the finish
line at vb= 42 km/hr (5 times as fast as the
runner). When the bird reaches the finish
line, it turns around and flies directly back to
the runner.
Answer:
Total distance traveled by bird is 10.5 km.
Explanation:
Given that,
Velocity of runner= 8.4 km/hr
Distance = 6.3 km
Velocity of bird = 42 km/hr
Suppose, How far does the bird travel?
We need to calculate the time of bird
Using formula of time
[tex]t=\dfrac{d}{v_{b}}[/tex]
Put the value into the formula
[tex]t=\dfrac{6.3}{42}[/tex]
[tex]t=0.15\ hr[/tex]
We need to calculate the distance runner travels during time period
Using formula of distance
[tex]d=v_{r}\times t[/tex]
[tex]d=8.4\times0.15[/tex]
[tex]d=1.26\ km[/tex]
We need to calculate the distance of runner to FL
Using distance
[tex]d'=6.3-1.26[/tex]
[tex]d'=5.04\ km[/tex]
We need to calculate the net closing speed between runner and bird
Using speed
[tex]v'=v_{r}+v_{b}[/tex]
[tex]v'=8.4+42[/tex]
[tex]v'=50.4\ km/hr[/tex]
We need to calculate the time for runner and bird to meet
Using formula of time
[tex]t=\dfrac{d}{v'}[/tex]
Put the value into the formula
[tex]t=\dfrac{5.04}{50.4}[/tex]
[tex]t=0.1\ hr[/tex]
We need to calculate the distance covered by runner
Using formula of distance
[tex]d=vt[/tex]
Put the value into the formula
[tex]d=8.4\times0.1[/tex]
[tex]d=0.84\ km[/tex]
We need to calculate the distance covered by bird to runner
Using formula of distance
[tex]d=vt[/tex]
Put the value into the formula
[tex]d=42\times0.1[/tex]
[tex]d=4.2\ km[/tex]
We need to calculate the total distance
Using distance
[tex]D=6.3+4.2[/tex]
[tex]D=10.5\ km[/tex]
Hence, Total distance traveled by bird is 10.5 km.

What is inertia?
Inertia is the resistance of an object to any change in motion. Inertia is proportional the mass of the object: in fact, as we experience in common situations, the larger the mass of an object, the more difficult it is to change its motion.
Inertia of an object is its inherited property. It is the measure of its mass. It is clear that the inertia of an object depends directly on its mass. Mass of an object is the amount of matter contained in it. It is same at every location.
Given that in the case four thing Biscuit, Feather, Elephant, a 1st grader out of which Feather, Biscuit, a 1st grader, Elephant is order of LEAST inertia to MOST inertia.

A ball at rest rolls across a frictionless floor at 12.0 m/s/s. How far will it travel in
8.00 s?
Answer:
The distance, d travelled by the ball is 768 metres.
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of final speed from the initial speed all over time.
Hence, if we subtract the final speed from the initial speed and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{initial \; speed - final \; speed}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]
v and u is initial and final speed respectively, measured in [tex]ms^{-1}[/tex]
t is time measured in seconds.
Given the following data;
Acceleration = 12.0m/s²
Time, t = 8secs
Velocity =?
First, we would calculate its velocity;
[tex]a = \frac{v - u}{t}[/tex]
Since the ball rolls at rest, initial velocity is zero (0).
[tex]V = a * t[/tex]
[tex]V = 12 * 8[/tex]
[tex]Velocity = 96ms^{-1}[/tex]
We can now solve for the distance;
[tex] Velocity = \frac{distance}{time}[/tex]
Therefore,
[tex]Distance = velocity * time[/tex]
[tex]Distance = 96 * 8[/tex]
Distance = 768m.

1. Use Newton’s Laws to explain why an object in space that has no motion has to be shoved to move in the first place.
2. Use Newton’s Laws to explain why a bowling ball will slow down and stop when rolled on a flat surface, like a street.
3. Use Newton’s Laws to explain why, when a 100Kg astronaut throws a 9Kg bowling ball forward in space, she moves backward but slower.
Answer:
An object in space that has no motion has to be shoved to move in the first place because of newton's first law of motion. A bowling ball will slow down and stop when rolled on a flat surface, like a street because of rolling friction which comes under Newton's first law of motion. When a 100Kg astronaut throws a 9Kg bowling ball forward in space, she moves backward but slower, this is because of Newton's third law of motion.Explanation:
This is due to Newton's first law of motion, explaining that an object in space that has no movement has to be moved to move in the first place. There is no external force or gravitational force in space, so the body can stay at rest and be forced to move first. Explaining why a bowling ball, like a street, can slow down and stop when rolled on a flat surface. This, again, is attributed to Newton's first law of motion. Due to rolling friction, it happens. The electrons on the surface of the ground in the atoms push against the electrons that touch the ground in the atoms on the surface of the ball as you roll a ball on the ground. A rolling ball stops when the surface on which it rolls opposes its motion. A ball rolling, due to friction, ceases.Explaining that when a 100 kg astronaut throws a 9 kg bowling ball forward in space, she travels backward but slower, due to Newton's third motion rule , which states that when force is applied, each body exhibits equal and opposite reaction. In this case, the astronaut's mass is greater, so the ball's acceleration will be less than the astronaut 's mass (since the body's mass is inversely proportional to the acceleration). Therefore, because of the reverse direction and slowly because of no gravitational force in space, the girl shifts backward while tossing the ball forward in space.Newton's Law of Motion -
FIRST LAW - The first law of Newton states that if a body is at rest or moving in a straight line at a constant speed, it will stay at rest or continue to travel at constant speed in a straight line unless it is acted upon by a force.
SECOND LAW - The second law of Newton is a quantitative explanation of the changes that a force can cause in a body 's motion. It states that the rate of change of a body's momentum in time is proportional to the force exerted on it in both magnitude and direction.
THIRD LAW - The third law of Newton notes that they apply forces to each other when two bodies interact, which are equal in magnitude and opposite in direction. Often known as the law of action and reaction, the third law is. In analyzing static equilibrium problems, where all forces are balanced, this law is essential, but it also applies to bodies in uniform or accelerated motion.
Hence , all the three explainations consist of newton's first and third laws of motion.

A man runs at 7.5 m s-1 due east across the deck of a ship which moves at 10.0 m s-1 due north. Determine the resultant velocity of the man( his velocity relative to the water)
Answer:
12.5 m/s North/east
Explanation:
I thought of it as a graph. I basically just found the distance between the points (0,0) and (10, 7.5)!
The resultant velocity of the man is 12.5 m/s.
What is velocity?The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.
Velocity of the man: v₁ = 7.5 m/s (due east )
Velocity of the ship: v₂ = 10 m/s. ( due north.)
Hence, the man and the ship move in perpendicular direction.
So, his velocity relative to the water = the resultant velocity of the man
= √(7.5² + 10²) m/s = 12.5 m/s.
Hence, resultant velocity of the man is 12.5 m/s.
