Answer:
d = 2*0.87 = 1.75 cm
Explanation:
by using flow rate equation to determine the speed in larger pipe
= 591.10 cm/s
= 5.91 m/s
by Bernoulli's EQUATION
solving for v2
v2 = 10.53 m/s
diameter can be determine by using flow rate equation
r = 0.87 cm
d = 2*0.87 = 1.75 cm
<span>A. accelerate toward the more massive object is your answer. In fact, even the acceleration with accelerate, also known as the jer.k. The more massive object will pull on the smaller object and the smaller object will increase its speed towards the more massive object.
idk why jer.k is a swear</span>
Answer:
U = 8.30×10-⁹J
Explanation:
m1 = m2 = 5.00kg masses of the spheres
d = 15.0cm = 15×10-²m
r = 5.10cm = 5.10×10-²m
R = d + r = 15×10-² + 5.10×10-²
R = 20.10 ×10-²m = 0.201m
G = 6.67×10-¹¹Nm²/kg²
U = Gm1×m2/R = potential energybetween the spheres
U = 6.67×10-¹¹×5.00×5.00/0.201
U = 8.30×10-⁹J
