Answer:
The answer is down below
Explanation:
Las arterias transportan la sangre desde el corazón y se ramifican en vasos más pequeños, formando arteriolas. Las arteriolas distribuyen sangre a los lechos capilares, los lugares de intercambio con los tejidos corporales. Los capilares conducen de regreso a pequeños vasos conocidos como vénulas que fluyen hacia las venas más grandes y finalmente regresan al corazón.
Answer:
M = 0.115 kg
Explanation:
given,
mass of arrow = 120 g = 0.12 Kg
speed of arrow before it strike apple = 29.7 m/s
distance traveled by the arrow stick combination = 9.30 m
height of the son = 1.85 m
weight of the apple = ?
now,
time of flight of arrow and apple combination
using equation of motion
t = 0.614 s
s = 15.15 m/s
using conservation of momentum
m v = (M+ m) s
0.12 x 29.7 = (M+ 0.12) x 15.15
M+ 0.12 = 0.235
M = 0.115 kg
mass of apple is equal to 0.115 Kg
Because the masses that you give are for blocks that are 1 cubic meter in volume, they also serve as the densities for the two metals that you are comparing.
<span>mass = density*volume </span>
<span>volume = (4/3)*pi*r^3 </span>
<span>volume of iron sphere = (4/3)*3.14*0.0201^3 = 3.40*10^-5 m^3 </span>
<span>mass of iron sphere = 7860* 3.40*10^-5 m^3 = 0.27 kg = mass of Aluminum Sphere </span>
<span>Volume of Al Sphere = 0.27/2700 = 9.90*10^-5 m^3 </span>
<span>Radius = cube root (volume / (4/3) / pi) = 2.87 cm. </span>
<span>I did this using the MS calculator, and I'm not 100% sure on the numerical answer, but the process is what you need to do to solve the problem. You should double check my answer.
hope this helped :)

Work = force × distance × cos(angle)
work = (25)(50)(cos (40))
work = 957.56 Joules
= 9.6x10^2 Joules
