Question
1. Earth interacts with every body found on its surface , pulling her toward its center , with an acceleration of 9.8 m / s2 , if time for some physical phenomenon the acceleration of Earth's gravity decreases 1.6 m / s2 identically equal to the acceleration of gravity on the moon. What will happen to the atmosphere surrounding the Earth? Choose the correct answer from the proposals. a) Continuous atmosphere surrounding the Earth as when the acceleration was 9.8 m / s2 .
b ) The atmosphere will be lost beyond Earth because the acceleration of 1.6 m / s2 can not keep her tied to Earth.
c ) The atmosphere will lose part of its atmosphere because the acceleration of 1.6 m / s2 will retain only a portion of mass of the atmosphere.
d ) The atmosphere will increase its atmosphere because the acceleration of 1.6 m / s2 stimulated to produce more Earth atmosphere.
2. The second law of Newton or law of acceleration explains the cause of the bodies acquire acceleration when interacting bodies . a photo is shown with four women in the back of a pickup truck , van at a speed of 30 MPH, if the moment 4 girls jump the road, suffers some change the speed of 30 MPH carrying the truck? answers about choose the right are provided .
a) The truck will increase your speed , ie accelerates , because by reducing the total mass of the truck, engine power act now on a lower total mass of the truck when the girls were .
b ) The truck does not change its speed, because the speed change is not related to the total mass of the truck.
c ) The truck slows because lower total mass of the truck will lower its speed .
d ) The truck will stop because any change in total mass of the truck is automatically stopped.
Explanation / Answer
PART 1
c ) The atmosphere will lose part of its atmosphere because the acceleration of 1.6 m / s2 will retain only a portion of mass of the atmosphere.
PART 2
a) The truck will increase your speed , ie accelerates , because by reducing the total mass of the truck, engine power act now on a lower total mass of the truck when the girls were .
