Answer:
9155 years old
Explanation:
We use the following expression for the decay of a substance:

So we first estimate the value of k knowing that the half-life of the C14 is 5730 years:

so, now we can estimate the age of the artifact by solving for"t" in the equation:

which we can round to 9155 years old.
Perpendicular slope would be 1/3. so the equation will be Y=1/3x -4
Temperature rise will be there in cylinder B more than in cylinder A because of internal energy.
what is internal energy?
The sum of the kinetic and chemical potential energies of all the particles in the system is the internal energy. Particles accelerate and pick up kinetic energy when energy is applied to increase the temperature.
Briefing:
Cylinder A uses the heat it absorbs to both work while expanding and to increase internal energy (or temperature).
While cylinder B solely uses the heat it absorbs to increase its internal energy
As a result, cylinder B's temperature rise is greater than cylinder A's.

Sounds are created when something vibrates (shakes back and forth), sending waves of vibrations into the ears of the listener. When a bell is struck, the metal vibrates. The vibrations travel through the air as sound waves.
