Answer the following question given this paragraph: a) The water forms the bottom of the tube and thus where the node of the wave will be. Thus the air column is where the sound wave can exist. The larger the air column, the larger the wavelength. Frequency is inversely proportional to wavelength, thus the tube with the smallest air column will have the highest frequency. So the answer is tube C. Q: In frequency, the larger the air column, the larger the what? Choices: - mass - gravity - absorption - wavelength A:
(Answer)
wavelength

Ques:Answer the following question given this paragraph: Figure 7.22 Osteoporosis Osteoporosis is an age-related disorder that causes the gradual loss of bone density and strength. When the thoracic vertebrae are affected, there can be a gradual collapse of the vertebrae. This results in kyphosis, an excessive curvature of the thoracic region. Q: What is the age-related disorder that causes the gradual loss of bone density and strength? Choices: - mitosis - arthritis - fibrosis - osteoporosis A:

Ans:osteoporosis
Ques:Answer the following question given this paragraph: When the wind drops fine particles of silt and clay, it forms deposits called loess ( Figure below ). Loess deposits form vertical cliffs. Loess can become a thick, rich soil. That's why loess deposits are used for farming in many parts of the world. Q: What do loess deposits form? Choices: - rotational cliffs - horizontal cliffs - diagonal cliffs - vertical cliffs A:

Ans:
vertical cliffs
