Which is the proper order of Earth's atmospheric layers from the surface up to space?
stratosphere, troposphere, mesosphere, thermosphere |
|
mesosphere, thermosphere, stratosphere, troposphere |
|
thermosphere, mesosphere, stratosphere, troposphere |
|
troposphere, stratosphere, mesosphere, thermosphere |
The troposphere is the closest layer to Earth, followed by the stratosphere, mesosphere, and finally the thermosphere which borders space.
"The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object." This describes which of Newton's laws of motion?
first |
|
fourth |
|
second |
|
third |
Newton's second law of motion states that The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. This law basically means that the greater the mass of an object, the more force is needed to overcome its inertia.

|
