Photosynthesis is a process in plants wherein light energy is converted to chemical energy, which is then stored as glucose. This is stored in the chloroplasts.
Photosynthesis is divided into two stages: the light and dark stage. In the light stage, the light energy is converted into ATP and NADPH, these are like the energy cells of the plant. After the light stage, the ATP and NADPH that were produced are used in the dark stage. The dark stage will use these energy cells to transform carbon dioxide into sugar.
Answer:
Therefore, a. chemical energy plant store when light is transformed during photosynthesis.
Explanation:
Photosynthesis is the process plants and some algae use to convert light energy to chemical energy stored as sugar within chloroplasts .
Photosynthesis is 6CO2 + 6H20 + light energy = glucose + 6 oxygen.
Photosynthesis is divided into two main stages: light reaction and dark reaction. The light reaction converts light energy into adenosine triphosphate,
B. The work done is equal to the area under the curve.
C. Work cannot be determined from this type of graph.
D. The work done is equal to length of the curve.
E. The work done is equal to the slope of the curve.
Answers
With a force/distance graph, the work is the area under the graph.
If the graph is curved, broken, or some other screwy shape that makes it difficult to
get the area in any simple way, then work is the integral of the function represented
by the graph.
Final answer:
The work done by a force over a given displacement, as represented in a force versus position graph, is equal to the area under the curve.
Explanation:
In a force versus position graph, the work done by the force over the given displacement is represented by the area under the curve. The work done is the integral of the force with respect to displacement which, in a graphical representation, translates to the area under the curve of the force versus position graph. For example, if the force is constant, the graph will be a rectangle, and the work done will be the product of force (height of the rectangle) and displacement (width of the rectangle). If the force is variable, the area under the curve might need to be calculated by dividing it into small sections and summing up their areas.

Answer:
Magnitude of potential energy is increased by factor "2"
Explanation:
As we know that if two charge particles are placed at some distance "r" from each other then the electrostatic potential energy between two charge particles is given as
now we know that if the charge of one of the charge particle is increased to twice of initial charge then
now we can say from above two equations that
so on increase one of the charge to twice of initial value then the potential energy will become TWICE
What is the definition of law of conservation of energy
Answers
Answer:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. This is particularly confusing in the case of non-conservative forces, where energy is converted from mechanical energy into thermal energy, but the overall energy does remain the same. The only way to use energy is to transform energy from one form to another.
Explanation:
Hope this helps!
Answer:
means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.

Answer:
This new element belongs to the group 2.
Explanation:
In the periodic table, the vertical columns are called groups (or families). The elements in the same group share similar chemical and physical properties.
One of these properties is the same amount of outer valence electrons.
For example, in the group 1 the elements have 1 outer valence electron (If we assume that the element is in a neutral state which is without electrical charges).
If this new element has 2 electrons in its outer level it will belong to the group 2. The group 2 is well-known as alkaline earth metals.
For example, the magnesium (Mg) and the calcium (Ca) belong to the group 2.

The speed of the plane without a wind is 430 miles/hr and speed of the wind is 20 miles/hr.
What is Speed ?
Speed is a rate of change of distance with respect to time. i.e. v=dx÷dt. Speed can also be defined as distance over time
i.e. speed= distance ÷ time
it is denoted by v and its SI unit is m/s. it is a scalar quantity.
Speed shows how much distance can be traveled in unit time.
To find dimension for speed is, from formula
Speed = Distance ÷ Time
Dimension for distance is [L¹] ,
Dimension for Time is [T¹],
Dividing dimension of distance by dimension of time gives,
{L¹] ÷ [T¹] = [L¹T⁻¹]
Dimension for speed is [L¹T⁻¹].
Consider,
Speed of the plane = v
Speed of the wind = u
Speed of the wind in the direction of wind is,
v + u = 450 miles/hr.....1
Speed of the wind in the opposite direction of wind is,
v - u = 410 miles/hr.....2
Adding equation 1 and 2
2v = 860
v = 430 miles/hr
Subtracting equation 1 and 2
2u = 40
u = 20 miles/hr
Hence the speed of the plane without a wind is 430 miles/hr and speed of the wind is 20 miles/hr.
