<span>This statement is true - humans require a certain percentage of body fat to function effectively. As a result of childbearing, women's bodies require a higher level of body fat than men: roughly 10-13%, compared to 2-5%. </span>
Answer:
the object is no longer in equilibrium .
I have a hunch that you've got the <em>question</em> totally covered, and what you actually need is the <em>answer.</em>
- Kinetic energy = (1/2) (mass) (speed²)
Multiply each side by 2 : 2 x KE = (mass) ( speed²)
Divide each side by (mass): Speed² = 2 x KE / mass
Square root each side: <em>Speed = √(2 KE/mass)</em>
Look at that ! The question GIVES you the KE and the mass. All you have to do is plug those 2 numbers into the right side of that equation, turn the crank, do the arithmetic, and the speed falls out.
I get 200 m/s . You need to check my work.
(IF that's correct or anywhere close, it's equivalent to something around 447 miles per hour, which is very reasonable for a cruising airliner.)
clay or shale not able to be moved through
This statement is true. The greater the mass is in an object, it is indeed the higher resistance to a change in movement the object will have. That only mean that the mass of an object and its resistance to change of movement is directly proportional.
