Hey!

--------------------------------------------------

$\Large\boxed{\mathsf{Option~D}}$

We can automatically eliminate option A and C because finding fossils isn't just trying to find the evolution of whales or bird. Archaeologists use fossils to see how animal evolve over a certain period of time. While they can build animals will the fossils they find but that isn't the most important use of fossils.

--------------------------------------------------

$\Large\boxed{\mathsf{Option~A}}$

Typically scientists you radioactive dating to find how old a fossil. In this case that isn't an option. I chose option A because scientists can use shape of the fossil to determine what species its from and what part of the body it is.

Answer:

a)11.25 J

b)Number of revolution = 1

Explanation:

Given that

Radius ,r= 0.8 m

m= 0.3 kg

Initial speed ,u= 10 m/s

final speed ,v= 5 m/s

Initial energy

$KE_i=\dfrac{1}{2}mu^2$

$KE_i=\dfrac{1}{2}0.3\times 10^2$

KEi= 15 J

Final kinetic energy

$KE_f=\dfrac{1}{2}mv^2$

$KE_f=\dfrac{1}{2}0.3\times 5^2$

KEf=3.75 J

The energy transformed from mechanical to internal = 15 - 3.75 J = 11.25 J

The minimum value to complete the circular arc

$V=\sqrt{r.g}$

Now by putting the values

$V=\sqrt{0.8\times 10}$

V= 2.82 m/s

So kinetic energy KE

$KE=\dfrac{1}{2}mV^2$

$KE=\dfrac{1}{2}0.3\times 2.82^2$

KE=1.19 J

ΔKE= KEi - KE

ΔKE= 15- 1.19 J

ΔKE=13.80 J

The minimum energy required to complete 2 revolutions = 2 x 11.25 J

= 22.5 J

Here 22.5 J is greater than 13.8 J.So the particle will complete only one revolution.

Number of revolution = 1

Is it possible for one energy store to transfer into another energy store ?Explained answer

liraira [26]

Answer:

Yes

Explanation:

Energy can be transferred from one object to another or between energy stores within the same object. For example on a pool table when white ball hits another ball energy is transferred from the kinetic store of the white ball to the kinetic store of the other ball.
