In photosynthesis, what two compounds are produced during the light-dependent reaction then used in the light-independent reaction?
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

If a person pulls a cart to the right at 5N of force and another person pulls to the left with a 15N of force? What is the net force and it what direction
Answer:
The net force is 10 [N] acting to the left
Explanation:
To solve this type of problem we must make a sum of the forces acting on the cart, since the forces are vectors, we know that vectors can be added, In this way forces that go in the same direction are added and forces in opposite directions are subtracted.
FL = force to the left = - 15 [N]
FR = force to the right = 5 [N]
FT = Resultant force [N]
- 15 + 5 = FT
FT = - 10 [N]
The negative sign tells us that the force acts to the left.

Patty decides to try another experiment. From the
same branch, she drops a large, heavy rock and a
small pebble. What would happen this time?
Answer: They will fall at the same time
Explanation:I had a google doc about this
When air resistance is considered, the effect of the air resistance will cause the rock to fall faster than the pebble which will be delayed due to its lesser weight. In the absence of air resistance, both rock and pebble will fall down at the same time.
What are free fall and air resistance?Free fall is a motion of an object in which the force of gravity is the only force acting upon it. A body moving upwards would not be considered to be falling. But if the body falls under the effect of the force of gravity, it is said to be in free fall.
Free fall is a type of motion in which no air resistance is considered and the force acting upon an object is only gravity. All bodies under such conditions fall with an equal rate of acceleration, regardless of their masses.
As a body falls through the air, have suffered some degree of air resistance. Air resistance is the collisions of the surface of an object with molecules present in the air. The factors that have a direct effect on the amount of air resistance are the cross-sectional area and the speed of the object.
As the rock had greater weight than the pebble in the absence of air resistance it will fall faster than the pebble.

B. When researchers draw conclusions that are consistent with their observations.
C. When researchers blind themselves to participants in the groups, so they don't accidentally reveal the information.
D. When the personal opinions, Ideas, or judgments of the researchers influence their research.
When the personal opinions, Ideas, or judgments of the researchers influence their research, then the experimental investigation and observation are considered biased, therefore the correct answer is option D.
What is the scientific claim?Scientific claims are statements made in science based on an experiment.
These Scientific claims are backed by experimental data and their true results obtained from scientific investigation and experimentation.
The right response is option D because experimental study and observation are deemed biased when the researchers' own ideas, beliefs, or judgments affect their findings.

(1) A block of mass 800g is pulled from rest on a horizontal
frictionless bench by a steady force of F and it travels 16m in 2
seconds. Find:
(a) The acceleration?
(b) The value of F?
Answer:
a) 8m.[tex]s^{-2}[/tex]
b) 6.4N
Explanation:
a)Using [tex]s=ut+1/2at^{2}[/tex]
s=16
u=0
t=2
a=?
16=1/2a(4)
a=8m.[tex]s^{-2}[/tex]
b) F=ma
Where m is in kg
Convert 800g to kg
800/1000=0.8kg (1000g in a kg)
F= 0.8 x 8 = 6.4N
A general contractor drives 5 miles to the hardware store in 10 minutes. He shops for needed tools for 30 minutes, then drives to his customer’s home at an average speed of 45 mph. He arrives 20 minutes later. Calculate the average speed from the time the contractor leaves his office to the time he arrives at his customer’s home.
Given parameters:
Distance to hardware shop = 5 miles
Time to reach hardware shop = 10 minutes
Time spent at the shop = 30 minutes
Average speed to customer home = 45 mph
Time taken for the travel = 20 minutes
Unknown:
Average speed of the contractor = ?
Solution:
Average speed is the total distance covered divided by the total time taken.
Average speed = [tex]\frac{total distance}{total time taken}[/tex]
total distance = distance to hardware shop + distance to customer's home
We do not know the distance to customer's home but we have been given the speed and time, so we can find the distance.
Distance = speed x time
Convert the time to hrs and solve;
60 minutes = 1 hr
20 minutes = [tex]\frac{20}{60} hr[/tex] = [tex]\frac{1}{3} hr[/tex]
So, Distance = 45mph x [tex]\frac{1}{3} hr[/tex] = 15miles
Now;
Total distance = 5 + 15 = 20miles
Total time = time to reach hardware shop + time to reach customer's house
= 10 + 20
= 30 minutes
Convert the time from minutes to hrs;
60 minutes = 1hr
30 minutes = [tex]\frac{30}{60}[/tex] = 0.5hr
So;
Average speed = [tex]\frac{20}{0.5}[/tex] = 40mph
The average speed is 40mph

Three pucks A, B, and C are shown sliding across ice at the noted speeds. Air and ice friction forces
are negligible (they are assumed to not exist) Rank the forces needed to keep them moving
greatest to least. You must justify your answer
A=2 m/s
B= 4 m/s
C=6 m/s
The puck that required the greatest force to be stopped is puck C, followed by puck B and the least is puck A.
Applied force
The force needed to stop the pucks or applied to stop the pucks is determined by applying Newton's second law of motion as shown below;
F = ma
F = mv/t
where;
F is the applied forcem is the mass of the pucksv is the speed of the puckst is the timeFrom the quation above, the applied force is directly proportional to the speed of the pucks. Thus, the greater the speed of the puck, the greater the required force to stop the puck.
Therefore, the puck that required the greatest force to be stopped is puck C, followed by puck B and the least is puck A.

A mass is dropped from a height h above the ground, and freely falls under the influence of gravity. Which graphs here correctly describes the displacement and velocity of the object during the time the object is falling? Consider the "up" direction to be positive.
Which graph is it?
Answer:
B
Explanation:
The only force acting on the block is gravity, so the block has a constant, negative acceleration. This means the velocity of the block is decreasing at a constant rate, so the answer is B, D, or E. Velocity is the rate of change of displacement, and answer choice B is the only one that has a displacement graph that matches that idea.
Answer: Graph B here correctly describes the displacement and velocity of the object during the time the object is falling. Option B is correct.
It is given that the mass of an object is dropped from height 'h' above the ground and "up" direction is taken to be positive.
It is required to find the graph which describes the displacement and velocity of the object during the time the object is falling.
Which graphs here correctly describes the displacement and velocity of the object during the time the object is falling?If any body falls freely towards the ground, then its acceleration is decreasing constantly with respect to time. That means velocity of an object will also be decreased as shown in graph B. Also we know that velocity is the rate of change of displacement.
As it is given in question that up direction is positive then it is also considered that downward be negative means decreasing.
Therefore, both the quantities are decreasing. So graph B correctly describes the displacement and velocity of the object during the time the object is falling.
