The weight on the moon is....<br>that of earth.​
Elena L [17]

Answer:

16.5% that of on earth

Explanation:

from google:

Your weight on the Moon is 16.5% what you would experience on Earth. In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon.

2.) Explain why the starting angle doesnt impact the time it takes the pendulum to swing back and forth?​
melomori [17]

The starting angle θθ of a pendulum does not affect its period for θ<<1θ<<1. At higher angles, however, the period TT increases with increasing θθ.

The relation between TT and θθ can be derived by solving the equation of motion of the simple pendulum (from F=ma)

−gsinθ=lθ¨−gain⁡θ=lθ¨

For small angles, θ≪1,θ≪1, and hence sinθ≈θsin⁡θ≈θ. Hence,

θ¨=−glθθ¨=−glθ

This second-order differential equation can be solved to get θ=θ0cos(ωt),ω=gl−−√θ=θ0cos⁡(ωt),ω=gl. The period is thus T=2πω=2πlg−−√T=2πω=2πlg, which is independent of the starting angle θ0θ0.

For large angles, however, the above derivation is invalid. Without going into the derivation, the general expression of the period is T=2πlg−−√(1+θ2016+...)T=2πlg(1+θ0216+...). At large angles, the θ2016θ0216 term starts to grow big and cause

What will be the fundamental frequency and first three overtones for a 26cm long organ at 20°C if it is open ( at 20°C, the spee
kakasveta [241]

Explanation:

The frequency of an organ pipe if it is open is given by :

f=\dfrac{nv}{2l}

v is speed of sound in air is 343 m/s at 20°C

For fundamental frequency, n = 1

f=\dfrac{1\times 343}{2\times 0.26}\\\\f=659.61\ Hz

First overtone frequency,

f_1=2f\\\\f_1=2\times 659.61\\\\f_1=1319.22\ Hz

Second overtone frequency,

f_2=3f\\\\f_2=3\times 659.61\\\\f_2=1978.83\ Hz

Third overtone frequency

f_3=4f\\\\f_3=4\times 659.61\\\\f_3=2638.44\ Hz

Hence, this is the required solution.

The force (expressed in N), the egg experience upon hitting the ground is 3.5N.

<h3>What is Net force?</h3>

When two or more forces are acting on the system of objects, then the to attain equilibrium, net force must be zero.

Given is an 0.07 kg egg and toss if from a window 30 m above the ground. The egg reaches and maintains a falling speed of 0.5 m/sec. Upon reaching the ground, the egg rapidly decelerates to 0 m/sec over the course of only 0.01 seconds.

<h3>Average force = Mass x acceleration</h3>

F = m x (Vf -Vi)/t

F = 0.07 x (0 - 0.5)/0.01

F = -3.5N

Thus, the magnitude of force on egg upon hitting the ground is 3.5N.
