In a process called “photosynthesis,” plants use the energy in sunlight to convert CO2 and water to sugar and oxygen. The plants use the sugar for food; food that we use, too, when we eat plants or animals that have eaten plants and they release the oxygen into the atmosphere.
So it’s PHOTOSYNTHESIS
Answer:
B. Shear Modulus
Explanation:
In this scenario, the friction force between the sliding block and the floor causes the block to deform.
Hence, the elastic modulus which describes the relationship between stress and strain for a block of iron sliding across a horizontal floor is Shear Modulus.
Shear Modulus can be defined as the ratio of shear stress to shear strain with respect to a physical object.
This ultimately implies that, Shear Modulus arises as a result of the application of a shear force on an object or body which eventually leads to its deformation. Thus, this phenomenon is simply used by scientists to measure or determine the rigidity of an object or body.
Mathematically, Shear Modulus is given by the formula;
Where;
G is the Shear Modulus.
F is the force applied to the object.
A is the area of the object.
l is the length of the object.
Dx is the change in length.
Shear Modulus is measured in Pascals.
Answer:
no
Explanation:
this may be wrong, but i would assume no because they have to cover the same distance therefore the faster runner would cross the finish line first.
Answer:
The maximum distance Charles will push down the trampoline ≈ 0.342 m
Explanation:
The given parameters are;
The mass of the trampoline artist, m = 75 kg
The speed with which the trampoline artist lands, v = 9.0 m/s
The value of the spring constant of the trampoline, k = 52,000 N/m
Let x represents the maximum distance Charles will push down the trampoline
Therefore, we have;
Kinetic energy = 1/2·m·v²
The kinetic energy with which the trampoline artist lands = 1/2 × 75 × 9.0² = 3037.5
The kinetic energy with which the trampoline artist lands = 3037.5 J
The potential energy stored in a spring = 1/2·k·x² = The kinetic energy with which the trampoline artist lands
∴ 1/2 × 52,000 × x² = 3037.5
∴ x = √(3037.5/(1/2 × 52,000)) ≈ 0.342
The maximum distance Charles will push down the trampoline = x ≈ 0.342 m
