Answer:

kinetic energy possessed by Ceres = 4.806 × 10^(29) J

Explanation:

We are given;

Estimated mass; m = 3 × 10^(21) kg

Orbital speed; v = 17900 m/s

Formula for kinetic energy is;

K.E = ½mv²

K.E = ½ × 3 × 10^(21) × 17900²

K.E = 4.806 × 10^(29) J

Thus;

kinetic energy possessed by Ceres = 4.806 × 10^(29) J

Answer: What type of chemical reaction is rusting of iron?

Rust is formed when iron reacts with oxygen in moist air. The following chemical equation represents the reaction: 4Fe + 3O2 → 2Fe2O3. Water is necessary for the oxidation reaction to occur and to facilitate transport of the electrons.

Answer:

The correct answer is - increased the global average temperature.

Explanation:

Combustion is the process that increases the carbon dioxide in the atmosphere, which results in entering more energy into the Earth system than existed from it.  Therefore, the amount of energy increased in the system of the earth or surface of the earth.

The reason behind it is that carbon dioxide trapped and redirects energy back toward the Earth's surface, which is absorbed by Earth's surface and surface increased, and global average temperature increased.

Combustion process increases the global average temperature of the earth by absorbing and emitting the energy revert back to earth.

Combustion is a process exothermic process in which organic molecules burns in the presence of oxygen to produce energy in the form of heat and light and CO₂ gas.

CO₂ gas is a green house gas which traps the energy of the atmosphere and revert back it into the earth surface, due to which temperature of the earth surface and atmosphere increases which results in the elevation of global average temperature.

Hence, combustion increases the global average temperature.

Answer: Harold car has better mileage

Explanation: US gallon is 3.785 litres and one mile is 1.6 km.

35 · 1.6 km/ 3.785 l = 14.8 km/l

The Harold's car has a fuel efficiency of 35 miles per gallon and has better gas mileage.

The efficiency is defined as the peak level of performance that uses the least amount inputs to achieve the highest amount of output.

Effectiveness is the ability to produce a better result, one that delivers more value or achieves a better outcome.

Efficiency is expressed as

Efficiency = output / input

The mileage of Harold's can be calculated as:

US gallon has 3.785 liters and 1 mile is 1.6 km

Thus  mileage = 35 x 1.6 km / 3.785 l

                       = 14.8 km/l

Mileage of Frank's car = 12 x 1.6 km / 3.785 l

                                     = 5.07 km/l

Thus, the Harold's car has a fuel efficiency of 35 miles per gallon and has better gas mileage.

Answer:

I believe it is hydrogen for the first and methane for the second.

Explanation:

Answer to 8: The most dangerous or harmful gas to humans in the atmosphere would be carbon dioxide. But reserchers have found that methane levels in ancient air samples and found that scientists have been vastly underestimating the amount of methane humans are emitting into the atmosphere via fossil fuels.

Answer to 7: The type of gases present are as critical to density as elevation and gravity, and all are interrelated. Certain atmospheric gases will create thick atmospheres. For example, atmospheres with abundant hydrogen tend to be thicker as gases will combine with hydrogen for greater mass.
