The answer is <span>b.
Sand 60
Clay 10
Silt 30
Sandy loam should be dominated by the sand. As the amount of sand increaed, the amount of slit needed to anchor the plants' roots to the sand will also be increased. Even though the amount is very little, 10% part of clay is still necessary for proper oxidation.</span>
<span>The hypothetical scenario that would result in the moon not having different phases would be t</span>he moon always stays in one position relative to the earth and sun. Why? If the moon didn't have an phases it would stay in one position. Phases mean change, and if you observe the moon every night, you'll see how it changes; it repeats, so thus it's a pattern.
So, your correct answer should be: <span>D.The moon always stays in one position relative to the earth and sun.</span>
Answer:
a) The speed of the block immediately after the collision is 
.
b) The impulse exerted on the block is 
.
Explanation:
Hi
a) As this is a perfectly elastic collision, we can use the formula 
, due 
, we obtain 
. Then with the data that we know 
and 
, therefore 
or adding uncertainty.
b) Now that we know the speed we can use 
The best answer would be C. Amplitude is the measure of the distance between the crest and the center of the line, or the distance between the trough and the center of the line (like wave height). High waves are a sea danger, especially to small ships and rowboats.
Answer:
Chemical reactions occur slower at lower temperatures and faster at higher temperatures. When you put a glow stick in cold water, the chemical reaction slows down but will last for a longer period of time. When you put a glow stick in hot water, the reaction speeds up but will be over quicker.
Explanation:
(self-explanatory)
I hope this helps, have a nice day.
