Answer:
There is a general trend of decreasing abundance with increasing atomic number, but elements with even atomic numbers tend to be more abundant than those with odd atomic numbers.
Explanation:
The average power is 20.3 kW
Explanation:
First of all, we calculate the work done on the car: the work-energy theorem states that the work done on the car is equal to the change in kinetic energy of the car, so we have
where
W is the work done
are the initial and final kinetic energy of the car
is the mass of the car
u = 0 is the initial velocity
v = 18.0 m/s is the final velocity
Substituting,
Now we can find the average power developed by the car's engine, which is given by
where
is the work done
t = 12.0 s is the time taken
Substituting,

It has a neutral charge which means it is equal.
Explanation:
In the trachea's inner layer, you have small, hair-like structures called cilia. Cilia move in rhythm to push mucus out of your trachea so that you either expel or swallow it
Acceleration = (final velocity^2 - initial velocity^2) / 2 * distance
Acceleration = (19.1^2 - 9.2^2) / 2 * 32
Acceleration = (364.81 - 84.64) / 64
Acceleration = 280.17 / 64
Acceleration = 4.3777m/s^2
