i know for sure the water one is correct with
A. Water is important to some organisms.
I'm 50/50 about the circulatory one BUT
A. carrying heat around the body.
that is your best bet
The equation
describes the relationship of he distance traveled and the time elapsed as one object travels a specified distance. This means that when t is 2 then d is 80. You know that a car is still in the air when the distance is a positive number and zero. The equation only holds true when t is at 0 to 3.
Answer:
yes
Explanation:
you will feel weary after shorter times
<span>A good conductor have lots of free electrons present in it As due to very less difference between valence band and conductive band so electrons can be easily available for conducting electricity

Answer:
They are <em>directly proportional</em> to gravitational force.
Explanation:
Newton's Law of Gravity states that . The two "m" values are the masses of the objects, <em>r</em> is the distance between their centers, and G is the gravitational constant. Notice how the "m" values are in the fraction's numerator (i.e., on top)? That means <em>increasing</em> even one of the objects' masses will <em>increase</em> the gravitational force. This is known as a <em>direct relationship</em>.
Of course, you could always use the wonderful table provided to solve this! You don't believe what I wrote above? Take on of the two objects' masses, divide the gravitational force by that number, and see what happens. Multiply the two masses together, and see what happens. Prove it for yourself!
I hope this increases your understanding of this concept. Have yourself a wondrous day, 'kay?
