Answer: (B) toward the right of the page To increase the radius of its orbit, the ship must attain a higher velocity, which requires an acceleration in the direction of its current velocity, or to the right of the page as depicted in this diagram. This will shift the orbit from a circular orbit to a ...

Build your own energy conservation machine Overview: At this point you’ve seen how in many simple machines forces can be changed by changing the distances over which they act, with the work done being the same. Do the same work by pulling or pushing over a longer distance, and it will take less aver ...

... these forces are related by Newton’s 3rd law (Third law pairs). An example of a third law pair is as follows: If you push the cart, there is a force from your hand on the cart. There is also a force from the cart on your hand. These two forces are a Newton’s third law pair. Newton’s third law pairs ...

... While running, a 70kg student generates thermal energy at a rate of 1200 W. To maintain a constant body temperature of 37◦ C, this energy must be removed by perspiration or other mechanisms. If these mechanisms failed and the heat could not flow out of the student’s body, for what amount of time cou ...
