What i got is that the squid is a carnivorous marine cephalopods the bigger it grows the higher up the food chain it goes that what sets them apart.
Answer:
<em>The power output of the engine is 1,000 Watt</em>
Explanation:
<u>Mechanical Power
</u>
Power is the amount of energy transferred or converted per unit of time. In the SI, the unit of power is the watt, equal to one joule per second.
The power can be calculated as:
Where W is the work and t is the time.
The engine does a work of W=60,000 J during t=60 s. Calculate the power:
P = 1,000 Watt
The power output of the engine is 1,000 Watt
Answer:
The resistance will be 2×R
Explanation:
We note that the resistivity of a cylindrical wire is given by the following relation;
Where:
ρ = Resistivity of the wire
R = The wire resistance
A = Cross sectional area of the wire = π·D²/4
L = Length of the wire
Rearranging, we have;
If the length and the diameter are both cut in half, we have;
L₂ = L/2
A₂ =π·D₂²/4 =
Therefore, the new resistance, R₂ can be expressed as follows;
Hence, the new resistance R₂ = 2×R, that is the resistance will be doubled.
True if you actually did it. false if you didn't
An evidence for the mammal competition hypothesis are the fossil records.
A gradual decline in the number of dinosaur species would likely mirror an equally gradual cause of their ultimate extinction. Conversely, a sudden "now you see them, now you don't" end to the dinosaurs implies a catastrophic cause. Depending on location and interpretation, the fossil record seems to say different things.
While mammals certainly prospered on the heels of the dinosaur extinction, it is unclear whether mammals and dinosaurs experienced little competition or if they regularly challenged each other for limited resources.
