Answer the following question given this paragraph: The bonfire from the opening image has a lot of thermal energy. Thermal energy is the total kinetic energy of moving particles of matter, and the transfer of thermal energy is called heat. Thermal energy from the bonfire is transferred to the hands by thermal radiation. Thermal radiation is the transfer of thermal energy by waves that can travel through air or even through empty space, as shown in the Figure below . When the waves of thermal energy reach objects, they transfer the energy to the objects, causing them to warm up. This is how the fire warms the hands of someone sitting near the bonfire. This is also how the sun's energy reaches Earth and heats its surface. Without the energy radiated from the sun, Earth would be too cold to support life as we know it. Q: How does heat travel from the sun to the earth? Choices: - through sound waves - through light waves - secondary radiation from the sun - thermal radiation from the sun A:
thermal radiation from the sun

Ques: Answer the following question given this paragraph: Zeros that show only where the decimal point falls are not significant. For example, the number 470,000 has just two significant figures (4 and 7). The zeros just show that the 4 represents hundreds of thousands and the 7 represents tens of thousands. Therefore, these zeros are not significant. Q: Are zeroes that show only where the decimal point fall significant or not significant? Choices: - neither - sometimes significant - significant - not significant A:
Ans: not significant

Ques:Answer the following question given this paragraph: Power is the rate that energy is released. The units for power are watts (W), which equal joules per second . For example, a 60 W light bulb transforms 60 joules of electrical energy into light and heat energy every second. Q: The rate that energy is released is known as Choices: - flow - heat - pressure - power A:

Ans:power
