The U.S. is one of several countries committed to reaching “net-zero” carbon emissions by 2050. This means that by 2050, all carbon dioxide emissions must be matched by the amount of carbon dioxide removed from the air. Why is it essential for all countries in the world to meet carbon reduction commitments like this
· A hypothesis about CO2 emissions.
The sun supplies about 1 kilowatt(s) of energy for each square meter of surface area (1 kW/m2kW/m2, where a watt = 1 J/sJ/s). Plants produce the equivalent of about 0.19 gg of sucrose (C12H22O11C12H22O11) per hour per square meter.

Which of the following energy resources are renewable: solar energy, coal, natural gas, geothermal energy, wind power?arrow_forwardThe sun supplies energy at a rate of about 1.0 kilowatt per square meter of surface area (1 watt = 1 J/s). The plants in an agricultural field produce the equivalent of 23 kg of sucrose (C12H22 O11) per hour per hectare (1 ha = 10,000 m²). Assuming that sucrose is produced by the reaction 12CO₂(g) + 11H₂O(l) → C12H22 O11 (8) + 1202 (9) AH = 5640 kJ calculate the percentage of sunlight used to produce the sucrose - that is, determine the efficiency of photosynthesis in this field.

- The best solar panels currently available are about 15% efficient in converting sunlight to electricity. A typical home will use about 40. kWh of electricity per day (1 kWh = 1 kilowatt hour; 1kW = 1000 J/s). Assuming 8.0 hours of useful sunlight per day, calculate the minimum solar panel surface area necessary to provide all of a typical homes electricity. (See Exercise 124 for the energy rate supplied by the sun.)arrow_forwardExplain why hydroelectric power and wind power are indirect forms of solar energy.arrow_forwardConsider the accompanying diagram. Ball A is allowed to fall and strike ball B. Assume that all of ball As energy is transferred to ball B at point I, and that there is no loss of energy to other sources. What is the kinetic energy and the potential energy of ball B at point II? The potential energy is given by PE = mgz, where m is the mass in kilograms, g is the gravitational constant (9.81 m/s2), and z is the distance in meters.arrow_forward

Calculate the monthly cost of operating each of the following: a 100 W light bulb, 5 h/day a 600 W refrigerator, 24 h/day a 12,000 W electric range, 1 h/day a 1000 W toaster, 10 min/dayarrow_forwardThe sun supplies energy at a rate of about 1.0 kilowatt per square meter of surface area (1 watt =1 J/s). The plants in an agricultural field produce the equivalent of 13 kg of sucrose (C12 H22 O11) per hour per hectare (1 ha : 10,000 m²). Assuming that sucrose is produced by the reaction 12CO2 (g) + 11H2O(1) → C12 H22 O11 (s) + 1202 (g) AH=5640 kJ calculate the percentage of sunlight used to produce the sucrose that is, determine the efficiency of photosynthesis in this field.

The surface area of Earth is approximately 197,000,000 square miles. How much of Earth's surface would we need to cover with solar energy collectors to power the planet for use by all humans? Assume that the solar energy collectors can only convert 10 % of the available sunlight into useful power.arrow_forward
