Solve the

potential energy at point B


PE = mgh


Where m is

the mass


G is the

acceleration due to gravity 9.8 m/s2


H is the height


PE = ( 1.5

kg) ( 9.8 m/s2) (0.5 m)


PE = 7.35 J



Solve the

velocity using the


KE = 0.5mv^2


Where ke is

the kinetic energy


M is the

mass


V is the

velocity


Since all

energy is converted to KE


So KE = PE



7.35 = 0.53(1.5)

v^2


V = 3.13 m/s

Explanation:

It is given that,

Mass of the ball, m = 1.5 kg

The ball is pulled to a height of 0.5 meters and then released.

The potential energy at point B is given by :

E_p=m\times g\times h

E_p=1.5\times 9.8\times 0.5

E_p=7.35\ J

To find the velocity at point A, it is required to use the conservation of energy as :

mgh=\dfrac{1}{2}mv^2

v=\sqrt{2gh}

v=\sqrt{2\times 9.8\times 0.5}

v = 3.13 m/s

Hence, this is the required solution.

Morgarella [4.7K]
The answer is algae.

Plankton includes a diverse group of organisms that live in the water, but are not capable of active swimming against the current. Therefore, since shark, squid and crab can swim and algae cannot, <span>among these groups </span>only algae can be a plankton.

A very rare disease will cause damage to the ribosomes in cells. what would be the direct effect of this disease?
DochEvi [55]

Answer:

A rare disease that causes damage to the cell's ribosomes will have as a direct effect the inability to perform protein synthesis.

Explanation:

Ribosomes are cellular organelles formed by proteins and a type of RNA called ribosomal RNA, whose function is to translate the genetic code of the mRNA codon sequence and convert it into amino acids. This implies the first step for protein synthesis to occur.

<em><u>If a rare disease could structurally or functionally affect the ribosomes, the translation of mRNA into amino acids could not occur, so protein synthesis in the cell would not be possible</u></em>.

The consequences of the lack of protein synthesis involve severe consequences on the structure and function of a living organism.

A grass snake living in northern England dies of natural causes. After a long period of time, its remains decay in the soil to b
Lubov Fominskaja [6]

Answer: C.  Dead snake fossilizing underground.

A fossil fuel is the fuel that is formed by natural processes, such as anaerobic decomposition of dead plants and animals underground. These organisms and their remains remain deep inside the depth of numerous layers of soil resulting in fuel produced after millions of years. A carbon sink refers to a natural or artificial reservoir that stores and absorbs atmospheric carbon by physical and biological process. The formation of fossil fuel inside the earth is carbon sink.  

Dead snake will be added as a matter on which biological activity called as decomposition will take place. The organic matter of dead snake will be decomposed by microbes in the soil. The organic matter being the source of carbon, after decomposition will become the reservoir of carbon in the form of fossil fuel.

Therefore, dead snake fossilizing underground is the example of carbon source becoming a carbon sink.
