What is Photosynthesis?Photosynthesis is the conversion of light energy to electrical energy in green plants and several other organisms. Green plants employ light energy during photosynthesis to convert water, carbon dioxide, and mineral into oxygen- and energy-rich organic molecules.
Photosynthesis is essential to the preservation of life on Earth, and its significance cannot be overstated. The amount of food and other organic materials on Earth would quickly decline if photosynthesis stopped. The majority of life forms would vanish, and eventually the atmosphere of Earth would be that few of gaseous oxygen.
The only organisms that might survive in such an environment would be chemosynthetic bacteria, which can use the hydrogen gas of specific inorganic materials and are not reliant on the conversion of light energy.

A 0.37 kg rock is thrown vertically upward from the top of a 37 m
cliff. When it hits the ground at the base of the cliff, the rock has a
speed of 33 m/s. Consider that air resistance is negligible. Use
conservation of total mechanical energy principle to find
a. The initial speed of the rock.
b. The greatest height of the rock as measured from the base of the
cliff.
c. Comment on the types of mechanical energy of the rock when
i) it is thrown upward, ii) it reached the maximum height, and
iii) it reached the base of the cliff.
(a) The initial speed of the rock is 19.1 m/s.
(b) The greatest height of the rock as measured from the base of the
cliff is 55.6 m.
(c) i. As the ball is thrown up, its kinetic energy is converted to potential energy.
ii. When then ball reaches the maximum height, its kinetic energy becomes zero and it will have maximum potential energy.
iii. When the rock reaches the base of the cliff, its potential energy becomes zero and it will have maximum kinetic energy.
Conservation of mechanical energyThe initial speed of the rock is determined by applying the principle of conservation of mechanical energy as shown below;
Ui + K.Ei = Uf + K.Ef
mghi + ¹/₂mvi² = mghf + ¹/₂mvf²
(0.37 x 9.8 x 37) + ¹/₂(0.37)vi² = (0.37 x 9.8 x 0) + ¹/₂(0.37 x 33)²
134.16 + 0.185vi² = 0 + 201.47
0.185vi² = 201.47 - 134.16
0.185vi² = 67.31
vi² = 67.31/0.185
vi² = 363.84
vi = √363.84
vi = 19.1 m/s
Height reached by the rock from top cliffvf² = vi² - 2gh
0 = vi² - 2gh
2gh = vi²
h = vi²/2g
h = (19.1)²/(2 x 9.8)
h = 18.6 m
Maximum height reached by rock from the base of the cliffThe maximum height from the base = 37 m + 18.6 m = 55.6 m
When the ball is thrown up, its kinetic energy is converted to potential energy.
When then ball reaches the maximum height, its kinetic energy becomes zero and it will have maximum potential energy.
When the rock reaches the base of the cliff, its potential energy becomes zero and it will have maximum kinetic energy.

What’s the weight of an object on Earth with a mass of 230 kg?
The weight of an object on Earth with a mass of 230 kg is 2256.3 newtons (n).
What is weight?The weight of an object is the force acting on the object due to the acceleration of gravity. It is defined as the vertical force experienced by a mass as a result of gravitation.
Weight is obtained from the product of mass and acceleration due to gravity (g). The object gets accelerated due to gravity when the object is in free fall. The value of g is 9.8 m/s².
From the given,
mass of an object = 230 kg
weight of an objcet=?
weight (w) = m×a, where m is the mass of the object and the unit of mass is the kilogram, a is the acceleration due to gravity and its unit is m/s², and w is the weight of the object and the unit of weight is Newton.
w = m×a
= 230×9.81
= 2256.3 N
w = 2256.3 N
Thus the weight of an object is 2256.3 N.

Answer:
Angular momentum increases and gravitational potential energy decreases after the bug lands.
Explanation:
After the bug lands, the rod begins to rotate. As the system was at rest before, when it begins to rotate, its angular momentum increases from zero to positive.
As the rod begins to rotate, the heavier mass of bug and sphere goes down while the lighter mass of sphere goes up. So the system's gravitational potential energy decreases.

A force of 345 N is applied to a 70 kg scooter. What will the scooter's
acceleration be?
Explanation:
here, force applied (N) = 345 N
or, mass of scooter (m) = 70 kg
now, acceleration (a) = ?
we know, force = mass × acceleration
or, 345 = 70 × acceleration
or, acceleration = 345/70
therefore, acceleration = 4.9 m/s2 (meter/second square)

a. We can calculate the amount of work by calculating the area under the graph.
first area (rectangular): 2.5 x 6 = 15
second area(trapezoid): 1/2 x (6+10) x 2.5 =20
total work done: 35 J

The diagrams show four bodies moving in the directions shown. The only forces acting on the bodies are shown in each diagram.
Which body gains the most kinetic energy when moving a distance of 1.0m ?
Answer:
C - the greatest net force is on c with 25N - 10N = 15N
a = F / M
a = (v2 - v1) / t so C has the greatest acceleration and will reach the greatest velocity
KE = 1/2 M v^2
The diagrams show four bodies moving in the directions shown. The only forces acting on the bodies are shown in each diagram. The option C body gains the most kinetic energy when moving a distance of 1.0m.
What is kinetic energy?When some amount of force is applied on a object it can store a energy in that object. That is the kinetic energy. Mathematically the mass of the object and its change in acceleration in that object makes the kinetic energy. It is a vector quantity.
How can we calculate the kinetic energy?
To calculate the kinetic energy we are using the formula,
U= (1/2)mv²
U = (1/2) ma²t²
Or, U= (1/2)ma × at²
Or, U= F × (1/2)at²
From this calculation we can see that if there is more force applied on a body that generates more kinetic energy on that object.
According to the question ,
Force of the object of Option A has (F) = f₂ - f₁
= (20 - 10)
= 10N
Force of the object of Option B has (F) = 10N
Force of the object of Option C has (F) = f₂ - f₁
=(25-10)= 15N
Force of the object of Option D has (F) = f₂ - f₁
= (30-30)
= 0N
According to the question, option C has the most amount of force and we know the more force generate the more kinetic energy. So it has the more kinetic energy.
We can easily say that, The option C body gains the most kinetic energy when moving a distance of 1.0m
