Answer:
7506 cal
Explanation:
Given: Mass of water = m = 13.9 grams.
Heat energy required to determine the conversion of 13.9 grams of water to steam or vapor is m L,
where L = Latent heat of vaporization of water=540 cal/g.
Q = mL = (13.9)(540) = 7,506 cal.
Answer:
Explanation:
Optical telescopes collect visible light. The three main types are reflecting telescopes, refracting telescopes, and catadioptric telescopes. Radio telescopes collect and focus radio waves from distant objects. Space telescopes orbit Earth, collecting wavelengths of light that are normally blocked by the atmosphere.
The net force acting on the block is ~
So, the Answer in the boxes will be ~
Answer:
The effort distance (also sometimes called the “effort arm”) is shorter than the resistance distance. Mechanical advantage = |Fr/Fe | where | means “absolute value.” Mechanical advantage is always positive.
