The answer is
-Small f and large D.
The explanation:
-A car jack acts as a machine, defined as an apparatus that aids individuals in exerting force more easily.
-Hence, by applying a small force to the jack, the height at which the car is elevated increases.
Machines are essential for people to amplify their strength; without them, lifting a car would be impossible.
Employing leverage or hydraulic principles, machines enhance your exerted force.
Utilizing a greater lever allows for extensive movement with minimal force, resulting in the opposite side moving shorter distances with an increased force.
Answer:
1. Reactions involving oxidation and reduction along with proton pumping
2. Reactions involving phosphorylation and proton pumping
Explanation:
During oxidative phosphorylation, there is a transfer of electrons from donors to acceptors, which constitutes a redox reaction.
These redox reactions liberate energy that is utilized to produce ATP. In eukaryotic cells, these reactions are performed by protein complexes found in the mitochondria, while in prokaryotic cells, the proteins are positioned in the intermembrane space of the cells. These interconnected protein complexes are referred to as electron transport chains.
Answer:
Height (h) = 17 m
Velocity (v) = 18.6 m/s
Explanation: This problem can be solved using kinematic motion equations.
Given Data
Initial velocity (u) = 0
Acceleration (a) = g
Time (t) = 1.9 seconds
First, we calculate the height.
Then, we find the final velocity
The acceleration graph is a linear representation described by y=9.8, as it remains constant:
The velocity graph can be represented by y=9.8x (where y signifies velocity and x indicates time):
The displacement graph can be described as y=4.9x^2 (with x as time and y as displacement):
These graphs apply exclusively from x=0 to x=1.9, so disregard other sections of the graphs.
I don't know that; sorry, I should just be removed from here.
