Answer:

The artifact is 11,460 years old.

<u>Explanation</u>:

Given that,

The half life of the carbon-14 is 5730 years and we are left with 255 of the sample of wood from an arti-fact.

So it takes 5730 years for the sample to reduce into half

Initially there will be 100% of the sample so

after first 5730 years, the sample reduces into 50% percent

Now the left 50% sample will take another 5730 years to decay into half of its amount.

after next 5730 years the sample reduces into 25% percent

So totally after 2 half-life the sample reduces into 25%

That is (5730 +5730) years = 11460 years

Which of these is an example of the meaning of inertia in physics

Vladimir79 [104]

The correct option is A.
In physics, inertia has to do with Newton's first law of motion which states that an object will continue in its state of rest or in motion unless it is acted upon by a force. Thus, inertia refers to the tendency of an object to continue its motion in a straight line at constant velocity. In the question given above, the car that its brake failed would have continue moving indefinitely if it did not crash into another car, that is, it will continue in its state of motion.

A mass of gas under constant Pressure occupies a volume of 0.5 M3 At a temperature of 20ﾟC using the formula for Cubic expansion

MAVERICK [17]

To answer this question, we must use the equation for the volumetric expansion of gases at constant pressure. This equation is given by:

$V=V_{0}(1 + \alpha(T_{2}-T_{1}))$
