Answer:
I believe whale fossils were found.
If you will be rinsing your regulator after removing it from the cylinder, you must make sure that the dust cap is firmly in place.
<h3>What is Dust cap?</h3>
A dust cap is a gently curved dome mounted either in concave or convex orientation over the central hole of most loudspeaker diaphragms.
Thus, if you will be rinsing your regulator after removing it from the cylinder, you must make sure that the dust cap is firmly in place.

Answer:
36.9 m/s
Explanation:
From;
v^2 = u^2 + 2as
Where;
v = final velocity =?
a = acceleration = 3.4 m/s^2
u = initial velocity = 0 m/s
s = distance covered = 200 meters
v^2 = 0^2 + 2 * 3.4 * 200
v^2 = 1360
v = √1360
v = 36.9 m/s
The average acceleration of the car in this process is -2 m/s²
<h3>
What is Acceleration ?</h3>
Acceleration can be defined as change in velocity per time taken. It is a vector quantity. That is, it has both the magnitude and direction. It is measured in m/s²
Given that a velocity of a car decreases from 28m/s to 20m/s in a time of 4 seconds. Then,
- Initial velocity u = 28 m/s
- Final velocity v = 20 m/s
From the definition of acceleration,
a = Δv / t
a = ( 20 - 28 ) / 4
a = -8 / 4
a = - 2 m/s²
Therefore, the average acceleration of the car in this process is -2 m/s² which mean that the car is decelerating.
