Answer:
Explanation:
<u>Uniform Acceleration
</u>
When an object changes its velocity at the same rate, the acceleration is constant.
The relation between the initial and final speeds is:
Where:
vf = Final speed
vo = Initial speed
a = Constant acceleration
t = Elapsed time
It's known a train moves from rest (vo=0) to a speed of vf=25 m/s in t=30 seconds. It's required to calculate the acceleration.
Solving for a:
Substituting:
Answer:
water forms hydrogen bonds
Explanation:
844J.
Assuming that there were no encumbrances during it's foreswing and it reached it's full potential at apogee.
The formula is
F_grav = G * m1 * m2 / r^2
G m1 and m2 are going to stay the same once chosen no matter what the distance is. The only thing that will change is the distance.
As the distance increases, the Gravitational Force will decrease. It will decrease by quite a bit.
As the distance decreases, the gravitational force will Increase.
The relationship is inverse. The moon travelling around the earth is one example. The earth travelling around the sun is another.
Answer:
The correct answer is detritic rocks.
Explanation:
Sedimentary rocks are rocks formed by the accumulation of sediments, particles of various sizes that are transported by water, ice or wind, which are subjected to physical and chemical processes, resulting in consolidated materials.
Sedimentary rocks formed from the accumulation of mineral deposits and rocks from erosion and deposited by gravity are called detritic rocks.
Have a nice day!
