Describe what happens when the rock on the top of a hill is pushed.

Zigmanuir [339]

Answer:

The precise point is that gravitational energy is potential energy unless it makes something move, and then the energy is converted to kinetic energy, no work can be done. So a big rock at the top of a hill has no kinetic energy. Its only when it rolls down that work is done, and this can be converted to useful energy.

Suppose that an Egyptian farmer claims to have discovered a linen burial cloth used during Egypt's Middle Kingdom some 4000 year

enyata [817]

Answer:

the cloth is old by 1,844 years

Explanation:

The computation is shown below:

The half-life of C^(14) is 5730 years

Now

$\lambda$ =1.210 × 10^-4 years^(-1)

Now

$N(t) = Ce^{-\lambda\times t}$

$0.8 \times (N_0) = N_0 \times e^{-\lambda \times t}\\\\ln(0.8) = (-\lambda \times t)\\\\t = \frac{-(ln(0.8))}{\lambda}$

$\lambda$ = .000121,

so t = 1844 yrs

hence, the cloth is old by 1,844 years
