What causes the temp to decrease with height in the mesosphere? Within the mesosphere, temperature decreases with increasing height, due to decreasing absorption of solar radiation by the rarefied atmosphere and increasing cooling by CO2 radiative emission. The top of the mesosphere, called the mesopause, is the coldest part of Earth’s atmosphere. Does temperature increase […]
What does the slope of displacement time graph indicate?
What does the slope of displacement time graph indicate? A sloping line on a displacement-time graph shows that the object is moving. In a displacement-time graph, the slope or gradient of the line, is equal to the velocity of the object. The steeper the line (and the greater the gradient) the faster the object is […]
What type of reaction is copper II chloride?
What type of reaction is copper II chloride? Copper(II) chloride is a mild oxidant. It decomposes to copper(I) chloride and chlorine gas near 1000 °C: 2 CuCl2 → 2 CuCl + Cl. Copper(II) chloride (CuCl2) reacts with several metals to produce copper metal or copper(I) chloride (CuCl) with oxidation of the other metal. What is […]
How long does it take a ball to fall from a roof to the ground 7.0 m below?
Which two branching connect the trachea to the lungs?
Which two branching connect the trachea to the lungs? At its bottom end, the trachea divides into left and right air tubes called bronchi (BRAHN-kye), which connect to the lungs. Within the lungs, the bronchi branch into smaller bronchi and even smaller tubes called bronchioles (BRAHN-kee-olz). Which two branching tubes connect the trachea to the […]
What is a specular material?
What is a specular material? (of reflected light) directed, as from a smooth, polished surface (opposed to diffuse ). A specular surface is a highly smooth surface. When the surface is very smooth, the reflected highlight is easy to see. Why can’t you see your image on a concrete wall? Answer. Answer: You get diffuse […]
What are the two main sources of thermal energy?
What are the two main sources of thermal energy? 1. Describe three ways in which thermal energy is found in nature. Thermal energy is found in the sun (solar energy), below Earth’s surface (geothermal energy), and in fire and other chemical reactions, and decay. What are main sources of heat? Sun is the biggest source […]
What are the 4 sources of stress?
What are the 4 sources of stress? The top four sources for stress are: Money. Work. Family responsibilities. Health Concerns. What are the 6 sources of stress? There are six main areas that can lead to work-related stress if they are not managed properly. These are: demands, control, support, relationships, role and change. What are […]
Why do I like to sleep on my stomach?
Why do I like to sleep on my stomach? Lots of people sleep on their stomach because they have a firm or uncomfortable mattress. In the side position, your hip and shoulder get more pressure, so that you turn to the stomach position automatically. Why do girls sleep with a pillow between their legs? It […]
What does the slope of position time graph represent?
What does the slope of position time graph represent? The slope of a position graph represents the velocity of the object. So the value of the slope at a particular time represents the velocity of the object at that instant. What is a real world example of negative slope? A simple example of negative slope […]
