The average speed is 0.55 m/s
<h3>What was his displacement?</h3>
Displacement is defined as the change in position of an object.
Mathematically,
D = Initial value - Final Value
D = 30 - 5 = 25m
Now , We have to find the average velocity,
Average velocity is calculated by the formula V = D/t,
where V equals the average velocity, D equals total displacement and t equals total time.
V = D/t
V = 25 m / 45s
V = 0.55 m/s
So , The average speed is o.55 m/s

Answer:
Or
2,668,320,000
Explanation:
Potential energy is given as the product of mass, acceleration due to gravity and height.
PE=mgh
Where m is the mass of pyramid, g is acceleration due to gravity and h is height at any point.
In reference to the earth, we substitute h for 34.0 m and g with 9.81 m/s2 then taking m as 8000000000 kg we get that
PE=mgh=8000000*9.81*34.0=2,668,320,000 J
In scientific notafion, this is expressed as
Displacement equals (Velocity times Time) plus half times the (acceleration times time squared). =. (48 * 4) + 1/2 * (12 *12^2) = 288meters
The answer is commensalism because commensalism is a relationship where an organism is benefitted and the other is neither benefitted nor harmed. The barnacle is being benefited and the whale is not being benefited or harmed.
