Answer:
Explanation:
A. The kinetic energy is the same as the initial potential energy:
PE = mgh = (215 N)(2.0 M) = 430 J
__
B. The velocity achieved by falling from a height h is given by ...
v = √(2gh)
v = √(2·9.8 m/s^2·2 m) = √(39.2 m^2/s^2)
v ≈ 6.26 m/s
Density = mass ÷ volume
D= 44g ÷ 8 cm^3
D = 5,5 (round it) 6 g/cm^3
The digestive system digests and makes nutrients out of food while the circulatory system distributes and circulates the nutrients i believe?
Answer:B
Explanation:
Galilean transformation are only approximately correct,while Lorentz transformation are more exact
