For a medium of exchange to function effectively in an economy, it must be recognized, approved, and willingly taken by all members of the public as settlement for debts and purchases. Which essential characteristic of money does this statement describe?

Cevabı ve açıklamayı göster

Cevap: General acceptability

Cevap

General acceptability
General acceptability is the prime quality of money. An item functions as money primarily because people have confidence that others will accept it in exchange for goods, services, or debt settlements.

Adım Adım Çözüm

1
Identify the key defining feature in the prompt
The prompt emphasizes that everyone in the economy recognizes, approves, and willingly accepts the item as payment.
Understanding the central attribute helps differentiate between physical traits and social/legal attributes of money.
2
Match the attribute to the correct characteristic
The willingness of all individuals to accept an item as payment defines 'General Acceptability'.
Without general acceptability, an item cannot serve as a medium of exchange regardless of its physical traits.

Cevap: 90 J K190\text{ J K}^{-1}

Cevap

The heat capacity of the block is 90 J K190\text{ J K}^{-1}.
The correct answer is 90 J K190\text{ J K}^{-1} because heat capacity is defined as C=QΔTC = \frac{Q}{\Delta T}. Dividing the absorbed heat of 3600 J3600\text{ J} by the temperature change of 40 K40\text{ K} yields 90 J K190\text{ J K}^{-1}.

Cevap: 5

Cevap

The time required for the sledge to come to a complete stop is 5.0 s5.0\text{ s}.
By Newton's second law in terms of momentum, the rate of change of momentum is equal to the applied net force (F=ΔpΔtF = \frac{\Delta p}{\Delta t}). Rearranging gives Δt=m(vu)F\Delta t = \frac{m(v - u)}{F}. Substituting m=8.0 kgm = 8.0\text{ kg}, u=15 m s1u = 15\text{ m s}^{-1}, v=0 m s1v = 0\text{ m s}^{-1}, and retarding force F=24 NF = -24\text{ N} yields Δt=8.0×(015)24=5.0 s\Delta t = \frac{8.0 \times (0 - 15)}{-24} = 5.0\text{ s}.

Apply the impulse-momentum theorem to determine the time duration.
Δt=ΔpF=120 kg m s124 N=5.0 s\Delta t = \frac{\Delta p}{F} = \frac{-120\text{ kg m s}^{-1}}{-24\text{ N}} = 5.0\text{ s}.

Cevap: 1.1 eV1.1\text{ eV}

Cevap

The maximum kinetic energy of the emitted photoelectrons remains 1.1 eV1.1\text{ eV}.
According to Einstein's photoelectric equation, Kmax=hfW0K_{\max} = hf - W_0. For incident light of frequency 8.0×1014 Hz8.0 \times 10^{14}\text{ Hz}, the photon energy is 3.3 eV3.3\text{ eV}. Subtracting the work function of 2.2 eV2.2\text{ eV} yields Kmax=1.1 eVK_{\max} = 1.1\text{ eV}. Because maximum kinetic energy depends solely on photon frequency and the metal's work function, changing the light intensity has no impact on KmaxK_{\max}.

Adım Adım Çözüm

1
Calculate the energy of the incident photon in Joules and convert to electron-volts (eV).
E=hf=(6.6×1034 Js)×(8.0×1014 Hz)=5.28×1019 J=5.28×10191.6×1019 eV=3.3 eVE = hf = (6.6 \times 10^{-34}\text{ J}\cdot\text{s}) \times (8.0 \times 10^{14}\text{ Hz}) = 5.28 \times 10^{-19}\text{ J} = \frac{5.28 \times 10^{-19}}{1.6 \times 10^{-19}}\text{ eV} = 3.3\text{ eV}.
Einstein's photoelectric equation requires knowing the energy of each incident photon.
2
Apply Einstein's photoelectric equation to calculate the maximum kinetic energy (KmaxK_{\max}).
Kmax=EW0=3.3 eV2.2 eV=1.1 eVK_{\max} = E - W_0 = 3.3\text{ eV} - 2.2\text{ eV} = 1.1\text{ eV}.
The work function (W0W_0) is the minimum energy needed to liberate an electron from the metal surface.
3
Analyze the effect of doubling light intensity at constant frequency.
KmaxK_{\max} remains 1.1 eV1.1\text{ eV}.
Light intensity is proportional to the number of photons striking the surface per second, affecting the rate of electron emission (photocurrent), but not the energy of individual photons or the maximum kinetic energy of the emitted electrons.

Under partnership law, a person who permits their name to be publicly displayed as a partner is classified as a nominal partner (or partner by holding out/estoppel). Even though they share no profits and contributed no capital, they are held personally and unlimitedly liable for business obligations to third parties who extended credit relying on that representation.

Adım Adım Çözüm

1
Identify the type of partner described in the scenario.
The individual is a nominal partner (or partner by holding out/estoppel) because he allows his name to be used by the business without contributing capital or participating in management.
Commercial law defines a nominal partner as one who lends their name and reputation to a firm.
2
Determine the legal liability associated with a nominal partner.
Under the law of partnership and estoppel, any person who represents themselves (or permits themselves to be represented) as a partner is liable to anyone who gives credit to the firm based on that representation.
Third-party creditors extend credit based on the creditworthiness and reputation of all ostensible partners.
3
Select the option that correctly describes this unlimited liability status.
The statement declaring unlimited personal liability to third parties as a nominal partner by holding out is the correct choice.
Nominal partners do not enjoy limited liability protection unless registered under a limited partnership act.

Cevap

4.48 dm34.48\text{ dm}^3
The balanced chemical equation indicates a 1:1 molar relationship between zinc and hydrogen gas. Reacting 13.0 g13.0\text{ g} of zinc corresponds to 13.065=0.20 mol\frac{13.0}{65} = 0.20\text{ mol} of zinc, yielding 0.20 mol0.20\text{ mol} of hydrogen gas. Multiplying by the molar volume at s.t.p. (22.4 dm3 mol122.4\text{ dm}^3\text{ mol}^{-1}) gives 0.20×22.4=4.48 dm30.20 \times 22.4 = 4.48\text{ dm}^3.

An electric heater rated at 100 W100\text{ W} is used to heat a metal block of mass 2.5 kg2.5\text{ kg} for 5 minutes5\text{ minutes}. If the temperature of the block increases from 25C25^\circ\text{C} to 45C45^\circ\text{C} and no heat energy is lost to the surroundings, what is the specific heat capacity of the metal?

Cevap: 600

Cevap

600 J kg1 K1600\text{ J kg}^{-1}\text{ K}^{-1}
The energy transferred by the 100 W100\text{ W} heater over 300 seconds300\text{ seconds} is Q=30,000 JQ = 30,000\text{ J}. Dividing this by the product of mass (2.5 kg2.5\text{ kg}) and temperature rise (20 K20\text{ K}) yields the specific heat capacity c=600 J kg1 K1c = 600\text{ J kg}^{-1}\text{ K}^{-1}.

Adım Adım Çözüm

1
Calculate total electrical heat energy supplied to the metal block
Q=P×t=100 W×(5×60 s)=30,000 JQ = P \times t = 100\text{ W} \times (5 \times 60\text{ s}) = 30,000\text{ J}
Heat energy supplied by an electric heater is given by power multiplied by heating time in seconds.
2
Calculate the change in temperature
ΔT=45C25C=20 K\Delta T = 45^\circ\text{C} - 25^\circ\text{C} = 20\text{ K}
Temperature difference is calculated by subtracting initial temperature from final temperature.
3
Solve for the specific heat capacity
c=QmΔT=30,000 J2.5 kg×20 K=600 J kg1 K1c = \frac{Q}{m \Delta T} = \frac{30,000\text{ J}}{2.5\text{ kg} \times 20\text{ K}} = 600\text{ J kg}^{-1}\text{ K}^{-1}
Specific heat capacity is the amount of heat energy required to raise the temperature of unit mass by one kelvin.
