[Sagot para sa’yo] Read the text below and answer the following questions Scientists believe that the atmosphere has five distinctive layers, but the boundaries between layers are not sharp and can be hard to measure precisely. The layers and some of their features are: Troposphere: This layer extends up to about 13 kilometers (km) from the Earth's surface. This layer holds 75% of the atmosphere's mass. As you go higher, the temperature drops from an average of about 13 deg * C near the Earth's surface to - 50 deg * C at the top of the layer. The air pressure also drops from 1000 millibars (mb) near the Earth's surface to 100 mb at the top of the layer. Stratosphere: This layer lies directly above the troposphere. It extends from about 13km to 48km above the Earth's surface. The temperature of the bottom of the layer is - 50 deg * C but at the top, its temperature is - 15 deg * C_{n} The air pressure at the bottom of the layer is about 100 mb but at the top of the layer, the air pressure is only I mb. Mesosphere: This layer lies directly above the stratosphere. It extends from about 48 km to 85 km above the Earth's surface. The temperature of the bottom of the layer is - 30 deg * C but at the top, it is only 90°C. The air pressure at the bottom of the layer is about 1 mb but at the top of the layer, the air pressure is only 0.01 mb. Thermosphere: This layer lies directly above the mesosphere. It extends from about 85 km to 700 km above the Earth's surface. The temperature of the bottom of the layer is - 90 deg * C but at the top of the thermosphere it can be 350 deg * C or higher. The air pressure at the bottom of the layer is about 0.01 mb but at the top of the layer the air pressure is very weak at about 0.000001 mb. Exosphere: This layer is the uppermost layer, and it extends 10,000 km into space. In fact, it blends with what scientists consider to be outer space! The pull of Earth's gravity is so small in this layer that molecules of gas escape into outer space. Questions: What physical quantities were mentioned that characterize each layer of the atmosphere? How far above the surface is the Troposphere? Which layer has the lowest semperature? Which layer is the tiniest?Which layer is the farthest from the surface? Synthesis: "What forms the basis for dividing the lowers of the atmosphere?

[Sagot para sa’yo] Activity Sheet No. 1 - ferdez Grade & Section: 69-led Date Answered: 3/5/2015 Score: UNIFORMLY ACCELERATED MOTION A. Directions: Write the word True if the statement is correct, if not write Eallse 1. The uniform motion indicates a constant velocity and covers the same amount of distance at a constant time interval. 2. In UAM, positive constant acceleration will result in a continuous increase in velocity. 3. Changing direction is also considered a manifestation of acceleration. 4. The velocity of the object thrown upward is maximum at the maximum height. 5. Objects moving under UAM will always have a constant velocity. 6. In free fall, the force acting on the object is only gravity. 7. Negative acceleration can continuously decrease the acceleration of a moving object 8. The velocity of dropped objects will be at maximum just the moment they hit the ground. 9. The graph of distance versus time of object under uniformly accelerated motion will manifest a curve or parabolic graph. 10. The graph of distance versus time of object under uniform motion will manifest a curve or parabolic graph. B. Write TRUE in the space provided if the following statements are correct and if false, change the underlined word or phrase to make the statement/s correct. 1. As the projectile reaches its highest peak, the vertical velocity continuously increases 2. When an object is horizontally launched its velocity is gradually increases. 3. In an angle-launched projectile the vertical velocity remains constant. 4. As the projectile reaches the maximum height its vertical velocity becomes zero. 5. The horizontal acceleration (ax) of a projectile is equal to -9.8m/s² 6. The horizontal velocity in a horizontally launched projectile is constant. 7. In angle-launched projectile, as the projectile rises its vertical velocity decreases. 8. The acceleration due to gravity is equal to zero. 9. As a projectile approaches the ground its vertical velocity decreases. 10.There is an external force acting on the horizontal motion of a projectile.
