Answer:
3 seconds
Explanation:
Applying,
Applying,
v = u±gt................ Equation 1
Where v = final velocity, u = initial velocity, t = time, g = acceleration due to gravity.
From the question,
Given: v = 0 m/s ( at the maximum height), u = 30 m/s
Constant: g = -10 m/s
Substitute these values into equation 1
0 = 30-10t
10t = 30
t = 30/10
t = 3 seconds
Answer:
Research towards increasing the understanding of progressive illnesses, such as Parkinson’s and Alzheimer’s diseases.
Explanation:
The Yerkes Primate center was established in 1930 by Robert Yerkes, in Orange Park, Florida. But was moved to its present location in Emory University.
The center has its focus on two major area of research, which are Immunology and Vaccine, and research towards increasing the understanding of progressive illnesses, such as Parkinson’s and Alzheimer’s diseases.
Im pretty sure its C- Wavelength
Ahhh... hello! I’ve done a science experiment that has asked this sort of question. Not as easy as it sounds... I know. I’ll tell you what I learned from that experiment. The answer will depend on the materials the ball is made of and then also your drop length. After these two things are determined, you can get a pretty close time and measurement. I hope this information helps. Have a great night!

<h2>
Option A is the correct answer.</h2>
Explanation:
When an elevator moves upward with consonant acceleration a, the overall acceleration on the body is given by
a' = a + g
So acceleration of pendulum is a + g.
We have equation for period of simple pendulum
In normal case a' = g here a' is more.
From the equation we can see that period of simple pendulum is inversely proportional to square root of acceleration.
Since acceleration increases period decreases.
Option A is the correct answer.
