Answer:
11.47answer
Explanation:
Height of the tower, s = 500 m
Velocity of sound, v = 340 m sˆ’1
Acceleration due to gravity, g = 10 m sˆ’2
Initial velocity of the stone, u = 0 (since the stone is initially at rest)
Time taken by the stone to fall to the base of the tower, t1
According to the second equation of motion:
S = ut1 + 1/2gt12
500 = 0 x t1 + 1/2 x 10 x t12
t12 = 100
t1 = 10s
Now, time taken by the sound to reach the top from the base of the tower, t2= 500/340 = 1.47 s
Therefore, the splash is heard at the top after time, t
Where, t= t1 + t2 = 10 + 1.47 = 11.47 s.
Answer:
Options <em>A, B and C</em> are correct.
Explanation:
A. Nutrition impacts memory when people are on the diet for three months
This option is correct because it was found that being on a high- protein or high-fiber diet for three months resulted in a significant improvement on memory performance tests. Note that "significant" here refers to statistical significance- which means the result is not due to random chance.
B. Nutrition has a bigger impact on memory when people are on the diet for three months than when they are on the diet for one month
This option is correct because when subjects were on a month long diet of either a standard diet, high- protein or high-fiber diet, it was found that memory performance is somewhat better for the high-protein and high-fiber groups than for the control group, but the effect of nutrition is not statistically significant. This means that the subjects on the high-protein and high-fiber groups did not conclusively do better on memory tests, and the result could be attributed to chance or other extraneous factors.
On the other hand, when subjects were on a high- protein or high-fiber diet for three months, it resulted in a significant improvement on memory performance tests- which means the result was not due to random chance.
C. There is not sufficient evidence to conclude that nutrition impacts memory when people are on the diet for one month
This option is correct because as stated above, it was found that memory performance is somewhat better for the high-protein and high-fiber groups than for the control group, but the effect of nutrition was not statistically significant- which means the results could be attributed to chance.
Under the tongue, inside the colon (not they smelly stuff that guys use) aaand I believe under the armpit....
Good luck~~
Answer: coenzymes
Explanation:
These are non-protein organic materials which binds with enzymes to catalyze a reaction. They can as well be referred to as a co factor, the reason been that the assist the activity of enzymes. Examples of coenzyme are vitamin B and S-adenosyl methionine. It is also very important to know that coenzymes cannot function alone.
