Capillaries unlike arteries and veins in mammals and other organisms due to their size and structure can branch out across multiple regions within the tissues, providing essential nutrients and other compounds.
The correct solution would be 2.
The mass of the (elevator + person) is (2,000 kg + 60 kg) = 2,060 kg .
The weight is (mass x gravity) = (2,060 x 10) = 20,600 newtons
Work = (force x distance) = (20,600 newtons x 24m) = <em>494,400 joules</em>
The speed, acceleration, and how much time it takes don't make any
difference, unless you want the average power during the lift.
Power = (work)/(time) =
494,000 J / (24/4 m) =
494,000 J / 6 sec = <em><u>82,400 watts</u></em> wow !
Answer:
<h3>The answer is 8.5 kg</h3>
Explanation:
The mass of the object can be found by using the formula
where
f is the force
a is the acceleration
So we have
We have the final answer as
<h3>8.5 kg</h3>
Hope this helps you
The choices are confusing. Air, oil, and alcohol are fluids at any reasonable temperature. Dry cement is not.
Answer:
0.687 m/s
Explanation:
Initial energy = final energy
1/2 mu² = mgh + 1/2 mv²
1/2 u² = gh + 1/2 v²
Given u = 2.00 m/s, g = 9.8 m/s², and h = 0.180 m:
1/2 (2.00 m/s)² = (9.8 m/s²) (0.180 m) + 1/2 v²
v = 0.687 m/s
