Answer:
a) I =0.0045 Ns
b) I= 005292 Ns
c) Push
Explanation:
1) Data given and useful definition
is the average force
represent the duration steps
Impulse is defined as: "The change of momentum of an object when the object is acted upon by a force for an interval of time"
2) Part a
We can calculate the impulse during the slap with this formula:
And replacing we got:
but on this case is moving on positive direction so then I=0.0045Ns
3) Part b
The impulse for this case would be given by:
Since the downward impulse on the lizard due to the gravitational force that represent that the average force would be the graviational force, and replacing we have:
And replacing the values we got:
4) Part c
Based on the values obtained for parts a) and b) we see that the impulse for the slapping is very low to surpass the impulse due to the gravitational force. So on this case needs to be push to provides the primary support for the lizard.
It would have to be the right type of metal like copper to run through it
Answer:
Explanation:
Area= pier^2
=( 1.88/2)^2= 0.0000000314m^2
Intensity= 0.0265/0.000000314
= 7962W/m^2
Pressure= 2*7962)/345= 5.13*10^-5pa
The transfer of energy through the food chain is around 10%. So basically we have a situation where the producers have 100% of energy, the organism that consumes them gets 10% of it, the organism that consumes that organism gets 10% of the 10% that organism got and so on to the top of the food chain.
Since the elephant seals consume 200,000 calories from the squid and small fish, this means that the squid and the small fish get 2,000,000 calories from their food, thus they are able to sustain the population of elephant seals.
We got to this result just by multiplying the number of calories the elephant seals get with the number 10, as they only get 10% of the calories of the squid and fish.
