Answer:
The ability to do work is the basic definition of energy. Energy is required to perform any task.
Nuclear fusion reactions happening on sun are the cause of heat, and sun energy.
Proton is the atomic particle with a positive charge just like the electron with the negative charge.
The objects have the kinetic energy during their motion. So the energy of moving object is kinetic energy.
When the objects interact then the friction between their surfaces produces the heat.
The vibration of molecules and the transfer of vibration to the other molecules is because of conduction. Conduction takes place through the vibration of molecules.
Atomic fusion requires extremely high temperatures to occur, that is why it is called thermonuclear.
Explanation:
The sun converts fusion energy into radiant (electromagnetic) energy.
<u>Explanation:
</u>
The energy which we get from the sun is called Solar Energy. The Solar Energy is nothing but, a form of energy, which is left out from an exothermic reaction. The radiant energy is the solar energy. The sun gets its energy through nuclear fusion.
High temperature causes the sun’s nuclei to separate from electrons. And with these electrons, the hydrogen ions combine to form Helium, which is the source of energy for the sun. As the nuclear fusion continues, the energy is derived and we get solar energy.
Answer:
shown below
Explanation:
2 x 10⁷ as a number is 20,000,000
20,000,000 - 10 = 19,999,990
It went 19,999,990 m/h
in km/h:
19,999,990 / 1000 = 19,999.99 km/h
in km/s
19,999,990 / 3,600,000 = ~5.56 km/s
in m/s
19,999,990 / 3600 = ~5555.56 m/s
Answer: Option B) Power
Explanation:
Power is the rate at which energy is expended per unit time. Hence, the rate at which electric energy is used is simply called electrical power.
Mathematically, the relationship between energy and power is:
Power = (Electrical energy /Time)
Hence, power consumption or electrical energy used in homes is rated in kilowatt per hour (kWh).
A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure.
