Answer the following question given this paragraph: The atmospheric pressure is converted from kPa to mmHg in order to match units with the table. The sum of the pressures of the hydrogen and the water vapor is equal to the atmospheric pressure. The pressure of the hydrogen is found by subtraction. Then, the volume of the gas at STP can be calculated by using the combined gas law. Q: The sum of the pressures of the hydrogen and the water vapor is equal to what? Choices: - moon pressure - adjacent pressure - precipitation pressure - atmospheric pressure A:
atmospheric pressure

Answer the following question given this paragraph: Life probably began in the oceans. No one knows exactly how or when. Life may have originated more than once. If life began before the Moon formed, that impact would have wiped it out. Then life would have had to originate again. Eventually conditions on Earth became less violent. The planet could support life. Q: Life probably began where? Choices: - rocks - the Sun - caves - oceans A:
(Answer)
oceans
Ques: Answer the following question given this paragraph: Just like it sounds, a wheel and axle is composed of two connected cylinders of different diameters. Since the wheel has a larger radius (distance) than the axle, the axle will always have a larger force than the wheel. The ideal mechanical advantage of a wheel and axle is dependent on the ratio between the radii:. Q: The ratio between the radii of a wheel and axle determines what? Choices: - fundamental mechanical advantage - introduced mechanical advantage - theoretical mechanical advantage - ideal mechanical advantage A:
Ans: ideal mechanical advantage
(Q).
Answer the following question given this paragraph: Electrical energy is transmitted by moving electrons in an electric current. In order to travel, electric current needs matter. It cannot pass through empty space. However, matter resists the flow of electric current. That's because flowing electrons in current collide with particles of matter, which absorb their energy. Some types of matter offer more or less resistance to electric current than others. Q: What is transmitted by moving electrons in an electric current? Choices: - potential energy - subsequent energy - stellar energy - electrical energy A:
(A).
electrical energy
Ques:Answer the following question given this paragraph: Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects are blurry. It occurs when the eyeball is shorter than normal. This causes images to be focused in back of the retina. Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they are on the retina instead of behind it. Q: Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects are? Choices: - inverted - darker - invisible - blurry A:

Ans:blurry
