Work is force times distance. If there's no distance, there's no work being done.
d = speed x time
distance = 29 x 30
distance = 870m

Explanation:
Without the metric system, we'd have a different International System of Units, the metric system is important because 1mm is 0.1cm, 1 cm is 0.01m, with the imperial system the conversion is tedious. The most important feature of the metric system is its base in scientific fact and repeatable standards of measurement

Answer:
a
The effect of a change in the price of a new pair of headphones on the equilibrium price of replacement tips ( dp/dpN) is
b
The value of Q and p at equilibruim is
and 5
The consumer surplus is
The producer surplus is
Explanation:
From the question we are told that
The inverse market demand is
The inverse supply function is
a
The effect of change in the price is mathematically given as
Now differntiating the inverse market demand function with respect to
We get that
b
We are told that $30
Therefore the inverse market demand becomes
At equilibrium
So we have
Where is the quantity at equilibrium
Substituting the value of Q into the equation for the inverse market demand function
5
Looking at the equation for we see that
For Q = 0
And for Q = 250
Hence the consumer surplus is mathematically evaluated as
Substituting value
And
The producer surplus is mathematically evaluated as
Answer:
he kinetic energy increases on the descent, being maximum at the lowest point of the trajectory.
Explanation:
In these semicircular sections the skaters slide from one side to the other, in the downward path their kinetic energy increases and their potential energy decreases; When it leaves the ramp and is in the air, the kinetic energy decreases rapidly, up to the point of maximum height where the kinetic energy is zero.
Consequently, the kinetic energy increases on the descent, being maximum at the lowest point of the trajectory.
