Sonja [21]

Answer:

The Precambrian (or Pre-Cambrian, sometimes abbreviated pЄ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time.

A chemist places a 100 g cube of each of the metals listed in the table on a separate hot plate. Based on the specific heat valu
Volgvan

The ranking of the metals in terms of how quickly they reach the target temperature are; Pb: 1, Sn: 2, Cu: 3, Fe: 4, Al: 5

Solving Specific Heat Capacity

The formula for quantity of heat from specific heat capacity is;

Q = m * C_s * ΔT

where;

Q is specific heat energy

C_s is specific heat capacity

ΔT is change in temperature

m is mass

Thus, the lower the specific heat or quantity of heat energy, the faster the change in temperature

Making ΔT the subject of the formula gives;

ΔT = Q / ( m * Cs)

We are told that the heat (Q) and mass (m = 100 g) are equal for the five samples. Thus, we have;

ΔT = [Q/m]/C_s

Since Q/m is constant for all the 5 samples, inputting the specific heat capacities means that the higher the specific heat capacity the slower the change in temperature but the lower the specific heat capacity, the quicker the change in temperature.

Solving online means that the fastest to slowest are;

Pb: 1, Sn: 2, Cu: 3, Fe: 4, Al: 5

NeX [460]

Answer:

I used the function 1-proportion z-interval on the calculator, where I inputted

  • Successes(x) = 64
  • Sample size(n) = 593
  • Confidence Level(C level) = 0.99

It would result in zInterval_1Prop 64,593,0.99: stat.results, where the values are shown below as:

  • Lower bound (CLower) = 0.075105
  • Upper bound (CUpper) = 0.140747
  • test statistic (p^) = 0.107926
  • Margin of error (ME) = 0.032821

Therefore, the 99% confidence interval would be around 0.11 ± 0.03 or range from 0.08 to 0.14.
