Answer:
Explanation:
Using the principle of conservation of energy, the potential energy is converted to kinetic energy, assuming any losses.
Kinetic energy is given by ½mv²
Potential energy is given by mgh
Where m is the mass, v is the velocity, g is acceleration due to gravity and h is the height.
Equating kinetic energy to be equal to potential energy then
½mv²=mgh
V
Making v the subject of the formula
v=√(2gh)
Substituting 9.81 m/s² for g and 20 m for h then
v=√(2*9.81*20)=19.799 m/s
Rounding off, v is approximately 20 m/s
Answer:
19.8 m/s
Explanation:
During the motion of a pemdulum bob, it casually converts kinetic energy to potential energy and vice versa.
A pendulum bob reaches its maximum speed at a position closest to its equilibrium position and has its lowest when it is farthest from the equilibrium position.
The maximum speed of a pendulum bob based on the mass involved and the maximum displacement from the equilibrium position is obtained from
Maximum kinetic energy = Maximum potential energy
Maximum potential energy occurs at the farthest point from equilibrium, that is,
P.E(max) = mgh
Maximum kinetic energy = ½mv²
½mv² = mgh
v = √2gh
g = acceleration due to gravity = 9.8 m/s²
h = farthest height from equilibrium position = 20 m
v = √(2×9.8×20) = 19.8 m/s
Hope this Helps!!!

v is what we are trying to find
u=0
a=4.9
s=200
v²=0²+2*4.9*200
v=√(2*4.9*200)
v=√1960
v=44.3 m/s (3 sf)
Hello!
A race car starting from rest accelerates uniformly at a rate of 3.90 m/s² what is the cars speed after it has traveled 200 m.
We have the following data:
Vf (final velocity) = ? (in m/s)
Vi (initial velocity) = 0 m/s (accelerated from rest)
d (displacement) = 200 m
a (acceleration) = 4.90 m/s²
Since we do not need to know the time elapsed during the movement, we apply the data of the question to the Equation of Torricelli, let us see:

Answer:
The candy before was fluffy, and the candy after was compacted.
Explanation:
Final answer:
The cloudy cotton candy was light and fluffy due to the air incorporated in it. After Chanel made it dense, the candy became compact and heavier, as she decreased the volume and maintained or increased the amount of sugar.
Explanation:
The cotton candy that Chanel had originally was described as being in a cloudy shape. This suggests that it was light, fluffy, and probably had a lot of air incorporated into it, which is why it was able to maintain such a shape. After she manipulated it to make it more dense, the cotton candy would have lost its cloudy appearance. Instead, it would have become heavier and more compact, because decreasing the amount of air in it increases its density. In other words, the volume of the cotton candy has decreased, but the amount of sugar within that volume has remained the same or increased.

Fermentation is the stage where it is not part of the cellular respiration. The answer is letter A. fermentation does not require oxygen to do respiration, rather, these are the glycolysis, Kreb’s cycle and electron transport.
Fermentation is NOT a stage of cellular respiration. Therefore option A is correct.
Fermentation is not a stage of cellular respiration. Cellular respiration is the process by which cells break down glucose and other organic molecules to produce energy in the form of ATP (adenosine triphosphate).
It occurs in three main stages: glycolysis, the Krebs cycle (also known as the citric acid cycle or the tricarboxylic acid cycle), and the electron transport chain.
Fermentation is an alternative metabolic pathway that occurs in the absence of oxygen (anaerobic conditions). It is a partial breakdown of glucose or other organic molecules that do not involve the complete oxidation of glucose to produce ATP.
Instead, it produces a small amount of ATP and end products such as lactic acid or ethanol.
Therefore option A is correct.

a graduated cylinder
an eye dropper
a beaker
a buret
Answers
Answer: a buret
A graduated cylinder and a beaker cannot be used. This is because the basic solution needs to be added drop by drop. This is not possible using a graduated cylinder or a beaker because it is difficult to pour drop by drop from these. An eye dropper cannot be used because it does not measure the volume being added.
A buret would be the best choice because it precisely measures the amount being added and we can add the basic solution to the acid drop by drop.
The process described is called a 'titration'
