Question 10: What is a K-turn?

Answer:

The three-point turn (sometimes called a Y-turn, K-turn, or broken U-turn) is the standard method of turning a vehicle around to face the opposite direction in a limited space, using forward and reverse gears. This is typically done when the road is too narrow for a U-turn.

Which do you think would cause the most destruction to the organisms in a food web: taking away the carnivores, taking away the

kotegsom [21]

Answer:

Explanation:

I do not have access to your diagram but based on what I know, a food web cannot sustain itself without decomposers. They are the main guys who break down dead animals, plants into organic or inorganic nutrients which are needed by the primary producers to grow. So if decomposers are not there then producers cannot produce and thus herbivores cannot live and carnovers die out as well. Hope this makes sense.

Carbon dating for archeological materials is based on the fact that a plant, after its death, stops absorbing radioactive C-14 a

Olin [163]

Answer:

t = 2212 years

Explanation:

In radioactive decay processes it is described by the equation

N = N₀ $e^{-\lambda t}$

to calculate the activity

$T_{1/2}$ = log 2 /λ

λ = log 2 / T_{1/2}

λ = log 2 /5715

λ = 5.267 10⁻⁵

now the amount of carbon 14 is N₀ = 0.1%, the sample contains an amount of N = 0.089%

N / N₀ = e^{-\lambda t}

-λ t = ln N / N₀

t = - 1 /λ ln N /N₀

t = 1 / 5.267 10⁻⁵ ln (0.089 / 0.1)

t = 2,212 10³ years

t = 2212 years

A student proposes a complex design for a steam power plant with a high efficiency. The power plant has several turbines, pumps,

masha68 [24]

Answer:

(a). max possible efficiency = 55.62%

(b). max power output = = 133.5 MW

Explanation:

From the question we were given the Maximum temperature in the system as

Tmax = 500°C

Minimum temperature in the system Tmin = 70°C

the Heat supplied to the boiler Qb = 240000 KJ/s

we use the temperature conversion factor from °C to K

given T(K) = T (°C) + 273

⇒ Tmax = 500 + 273 = 773 K

⇒ Tmin = 70 + 273 = 343 K

(a). we are to determine the maximum possible thermal efficiency;

(Πth)max = 1 - Tmin/Tmax

(Πth)max = 1 - 343/773 = 0.5562

(Πth)max = 55.62%

(b). to determine the maximum possible power output for the plant we have;

(Πth)max = Wmax/Qb

where Wmax rep the maximum power output

(Πth)max = 0.5562

Qb = 240000

∴ Wmax = 0.5562 × 240000 = 133505.6 Kw

Wmax = 133.5 MW

cheers i hope this helps

A 1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. The spring has an un

ZanzabumX [31]

Answer:

0.4167 ft/s

Explanation:

The law of conservation is applied to point A and B.

This gives:

$T_{A} + V_{A} = T_{B} + V_{B}$

Hence, $T_{A}$ is the kinetic energy at the position A

$V_{A}$ is the velocity at point A

Considering point A, the kinetic energy at the point will be:

$T_{A} = 0$

The potential energy will be:

$V_{A} = (V_{A})_{g} + (V_{A})_{c}$

Hence, $V_{Ag}$ is the potential energy and $V_{Ac}$ is the kinetic energy

The potential energy is given by the following:

$V_{Ag} = mgr$

substituting 1 lb for mg gives 0.4167 ft for r

Then the velocity, $V_{Ag} = 1lb * 0.4167ft\\ = 0.4167 ft$
