Answer:
Explanation:
tube:
f=v/4L = 343/(4*1.2)= 71.4583Hz tube's fundamental frequency
wire:
f=v/2L -> v=2Lf
v= 2*0.323*71.4583= 46.162m/s
ρ= 0.0095/0.323= 0.02941kg/m
v=√(T/ρ) -> T=v^2*ρ
T= 46.162^2*0.02941= 62.67[N] Tension of wire.
Answer:
0.42 meters/second
Explanation:
The total distance traveled by Mary is: 80 m + 125 m + 45 m = 250 m
We want the speed in meters/second, so we have to convert the 10 minutes elapsed during the trip into seconds. Then we need a conversion factor, 1 minute is equivalent to 60 seconds.
time = 10 minutes * (60 seconds/1 minute) = 600 seconds (notice that minute is cancelled because is multiplying and dividing)
Now, we can compute the average speed is as follows:
Average speed = total distance/time = 250 m/600 s = 0.42 m/s
Given that : d = 5sin(pi t/4), So, maximum displacement, d = 5*(+1) = 5 Also, maximum displacement, d = 5*(-1) = -5
Coulomb's law explains the force between the charges whereas Newton's law of gravitation explains the force between the masses. ... The electrostatic force may be positive or negative in the case of Coulomb's law but the force is always negative in the case of Newton's law of gravitation
Aside from filling lakes with sediment, it is a biological concern which is the population of fish and other aquatic organisms will decrease due to the dissolved oxygen in the water decreasing dramatically. I hope my answer has come to your help. God bless and have a nice day ahead!
