Answer:
D) Quadruple.
Explanation:
We will use the second equation of motion to solve this problem:
where,
s = distance travelled by the rock
vi = initial speed of rock = 0 m/s
t = time taken
g = acceleration due to gravity on the surface of the moon
Therefore,
----------- equation (1)
Now, we double the time:
using equation (1):
s' = 4s
Hence, the correct option is:
<u>D) Quadruple.</u>
Answer:
The epithelial cell shape and stratification are related to its function. For example, the skin is specialized to act as a "physical" barrier to the outside world. This barrier is both structural (multi-layered) and chemical in nature. Another example is the cells that make up the tubular elements of the kidney.
Explanation:
Use v = vi + at
v = 5.3 m/s + (15 m/s^2)(2.1 s)
v = 5.3 m/s + 31.5 m/s
v = 36.8 m/s
