A chair is at rest on the floor. The chair absorbs thermal energy from the floor, and begins moving spontaneously with kinetic e
dolphi86 [110]

Answer:

D- Only the 2nd law of thermodynamics

Explanation:

It violates 2nd law because according to 2nd law of thermodynamics, it is impossible that the sole result of a process is is to absorb energy and do equivalent amount of work. so some heat must lose to surrounding which is not specified here. so it violates 2nd law.

so option D is correct

write down the interrelationship between distance covered , initial velocity and timetaken by a moving body.​
Tamiku [17]

Answer:

s = v_it + \frac{1}{2}at^2

Explanation:

The interrelationship between the distance covered by a body, the initial velocity of the body, and the time taken by the moving body during its motion is given by the second equation of motion.

The second equation of motion is given as follows:

s = v_it + \frac{1}{2}at^2

where,

s = the distance covered by the body

vi = initial velocity of the body

t = time taken by the body during motion

a = acceleration of the body

The age of a piece of wood from an archeological site is to be determined using the Carbon-14 method. The activity of the sample
Bond [772]

Answer:

4276.98 years

Explanation:

t = age of the sample in numbers of years

T = half life of the carbon-14 isotope = 5730 yrs

λ = decay constant of carbon-14

decay constant is given as

\lambda =\frac{0.693}{T}

\lambda =\frac{0.693}{5730}

\lambda = 0.000121

A₀ = activity of Carbon-14 in living plants

A  = activity of Carbon-14 after time "t" = (0.596) A₀

Using the equation

A = A_{o} e^{-\lambda t}

(0.596) A₀  = A_{o} e^{-0.000121 t}

0.596 = e^{-0.000121 t}

t = 4276.98 years
