Gibbons, small Asian apes, move by brachiation, swinging below a handhold to move forward to the next handhold. A 9.4 kg gibbon

has an arm length (hand to shoulder) of 0.60 m. We can model its motion as that of a point mass swinging at the end of a 0.60-m-long, massless rod. At the lowest point of its swing, the gibbon is moving at 3.4 m/s . What upward force must a branch provide to support the swinging gibbon?

Answer:

upward force acting = 261.6 N

Explanation:

given,

mass of gibbon = 9.4 kg

arm length = 0.6 m

speed of the swing

net force must provide

F_{branch} + F_{gravity}=F_{centripetal}

force of gravity = - mg

F_{branch}=F_{centripetal}-F_{gravity}

                        = \dfrac{mv^2}{r} + mg

                        = m(\dfrac{3.4^2}{0.6} +9.8)

                        =9 x 29.067

                        = 261.6 N

upward force acting = 261.6 N

Two forces Upper FSubscript Upper A Baseline Overscript right-arrow EndScripts and Upper FSubscript Upper B Baseline Overscript
Pavel [41]

Answer:

Part a)

F_A = 4.59 N

Part B)

F_B = 1.28 N

Explanation:

As we know that when both the forces are acting on the object in same direction then we will have

F_A + F_B = ma

as we know that

a = 0.554 m/s^2

m = 10.6 kg

now we will have

F_A + F_B = 10.6(0.554)

F_A + F_B = 5.87 N

Now two forces are in opposite direction then we have

F_A - F_B = 10.6(0.313)

F_A - F_B = 3.32 N

Part A)

Now we will have from above two equation

F_A = 4.59 N

Part B)

Similarly for other force we have

F_B = 1.28 N

If a wave is traveling at 200 m/s and it’s wavelength is 0.5 meters , what is the frequency of the wave
Mrrafil [7]

Answer:

400 Hz

Explanation:

The frequency of a sound wave is found by the velocity/wavelength.  Therefore, f = v/wavelength = (200 m/s)/(0.5 m) = 400 Hz

I hope this helps! :)

The U.S. Navy has long proposed the construction of extremely low frequency (ELF waves) communications systems; such waves could
Artyom0805 [142]

Answer:

length of a quarter wavelength antenna for transmitter elf waves are zero

Explanation:

Find the length of a quarter wavelength antenna for transmitter elf waves

Given information

frequency (ELF waves) → 77Hz

Speed of light → 3\times10^8m/s

v=\lambda f-------------1

where

\lambda\\ → wavelength of the antenna

f → frequency of the ELF waves

v →  speed of light

so rewrite the equation in \lambda from

\lambda=\dfrac{v}{f}

Substitute 3\times10^8m/s = v

Substitute 75Hz = f

\lambda=\dfrac{3\times10^8m/s}{77Hz}

=3.9\times 10^6m

since we get this value,but this size of antenna mount on submarine is not possible.

so \lambda is zero
