The distance between a trough and a crest is double the amplitude.
The distance between trough and crest is (9m - 6m) = 3m.
So the amplitude of those water waves is (3/2) = 1.5 meters.
For this question, we really don't need to know how far apart the crests are, or how often they pass. There may be more parts to the question, for which that information is needed.
For example:
-- What's the wavelength of the waves ? 8 meters.
-- What's the period of the waves ? 4 seconds.
-- What's the frequency of the waves ? 1 / (4 seconds) = 0.25 Hz.
-- What's the speed of the waves ? (8 m) x (0.25 Hz) = 2 m/s
<span>In order to determine the speed of the entire assembly, we employ conservation of momentum. Momentum p = mv where m is the object's mass and v is the velocity.
The putty ball's initial momentum p1 = 0.3kg*6m/s = 1.8 kg*m/s
That momentum is conserved, so the momentum of the new system having mass 0.3 kg + 1.2 kg = 1.5 kg is:
1.8 kg*m/s = 1.5kg*v. Solving for v, we find that the velocity is 1.2 meters/second.</span>
Answer:
it is the force resisting the relative motion of solid
surfaces, fluid layers
<span>As the clay content increases, there is more surface area in the soil for organic matter to adsorb to, which decreases the rate of decomposition.</span>
An example of a negative incentive for producers is the
sharp increase in production costs. Producers are the one who manage the production
costs and even the production budget. Anything that relates the production
department is entitled to the management of production producers.
There is what we called positive and negative incentives and
both of these can affect consumers and producers. Positive incentives are those
situations which will give a certain outcome that will benefit the producers,
for example, during the peak season there will be a high demand of products, and
this gives the chance of producers to demand a higher price from the consumers,
in this situation, there will be a big chance of increase sales. A sharp increase in production costs is a
loss for the producers. If there will be
an increase in production costs, the budget will be greatly affective and even
though it is not a peak season, there’s a big chance also to increase prices
which we know, consumers are not fond of.
