Answer:
The bicyclist's acceleration is 2.2m/s^2
Explanation:
Given
---- Initial Velocity
---- Final Velocity
---- Time
Required
Determine the acceleration
This will be solved using the first equation of motion

Substitute values for v, u and a

Solve for a

---- (approximated)
<em>Hence, the bicyclist's acceleration is 2.2m/s^2</em>
It has 52 Protons and 73 Neutrons
Correct answer is D.
Explanation:
A) is not correct answer because this type of theory can not become law. Laws are properties that are same in any part of universe. Nebular theory is not correct for every part of universe.
B) is not correct answer because this theory could be replaced if some evidence show that some other theory is more likely to be correct.
C) is not correct answer because the study has been done on other nebulas in our galaxy. There are many nebulas and by obserwing them this theory was developed.

<span>a=9.8m/s/s </span>
<span>v is velocity (the tower must be very high to be able to fall for 10 seconds!!!) </span>
<span>you work out the result now</span>
