Kinetic energy is is the energy of mass in motion basically the kinetic energy of an object is the energy it has because of its motion an example of kinetic energy would be, well let’s say you have a ball and you let that ball fall the potential energy then converts into kinetic energy or the energy associated with the motion and there are five types of kinetic energy like (radiant and thermal and sound and electrical and mechanical! Hopefully this help!

energy which a body possess by virtue of being in motion

ex: a river flowing at a certain speed comprises kinetic energy as water has a certain velocity and mass

Answer : The time passed in years is $2.74\times 10^2\text{ years}$

Explanation :

Half-life of carbon-14 = 5730 years

First we have to calculate the rate constant, we use the formula :

$k=\frac{0.693}{t_{1/2}}$

$k=\frac{0.693}{5730\text{ years}}$

$k=1.21\times 10^{-4}\text{ years}^{-1}$

Now we have to calculate the time passed.

Expression for rate law for first order kinetics is given by:

$t=\frac{2.303}{k}\log\frac{a}{a-x}$

where,

k = rate constant = $1.21\times 10^{-4}\text{ years}^{-1}$

t = time passed by the sample = ?

a = initial amount of the reactant disintegrate = 15.3

a - x = amount left after decay process = 14.8

Now put all the given values in above equation, we get

$t=\frac{2.303}{1.21\times 10^{-4}}\log\frac{15.3}{14.8}$

$t=274.64\text{ years}=2.74\times 10^2\text{ years}$

Therefore, the time passed in years is $2.74\times 10^2\text{ years}$

Can an object have both kinetic and potential energy? explain. um please help quick:(((

Alex Ar [27]

Answer:

Yes

Explanation:

An object can be above ground which would be potential energy, and be moving at the same which is kinetic energy.
