Suppose that instead of being inclined to Earth's orbit around the Sun, the Moon’s orbit was in the same plane as Earth’s orbit

around the Sun. In this hypothetical situation, approximately how many solar eclipses would occur each year?
Physics

d1i1m1o1n [39]3 years ago
8 0

Answer:

12

Explanation:

A solar eclipse occurs when the moon in between the sun and the earth. Since in reality, the moons orbit is inclined, this aligning doesnt occur often. But if the orbit of the moon were in the same plane as the earth orbit, and since the moon orbits the earth once a month, the three objects would align every month. This makes it 12 times in a year.

An open pipe, 0.29 m long, vibrates in the second overtone with a frequency of 1,227 Hz. In this situation, the fundamental freq
Andru [333]

Answer:

f = 409 Hz

Explanation:

We have,

Length of the open organ pipe, l = 0.29 m

Frequency of vibration of second overtone, f_2 = 1227 Hz

It is required to find the fundamental frequency of the pipe. For the open organ pipe, the frequency of second overtone is given by :

f_2=\dfrac{3v}{2l}

v is speed of sound

Let f is the fundamental frequency. It is given by :

f=\dfrac{v}{2l}

The relation between f and f₂ can be written as :

f_2=3f\\\\f=\dfrac{f_2}{3}\\\\f=\dfrac{1227}{3}\\\\f=409\ Hz

So, the fundamental frequency of the pipe is 409 Hz.

According to Coulomb’s Law, the force between two charged objects is related to _____.
Natasha_Volkova [10]

Answer:

A.) the inverse of the square of the distance separating them

Explanation:

Coulombs law states that "the force of attraction between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them."

Mathematically, F = kq1q2/r²

Where q1 and q2 are the charges

r is the distance between the charges.

According to the law, the force between two charged objects is related to the inverse of the square of the distance separating them.

An input force is applied to a 2 cm diameter piston. The piston compresses oil and is connected to a 4 cm diameter output piston
____ [38]

Answer:

4 times

Explanation:

Given:

diameter of the input piston, d_i=2\ cm=0.02\ m

diameter of the output piston, d_o=4\ cm=0.04\ m

In such mechanical arrangements the fluid acts as an incompressible link and the pressure remains uniform throughout the fluid bulk.

Then, by the Pascal's law:

\frac{F_i}{A_i} =\frac{F_o}{A_o}

where:

F_i\ \&\ F_o are the input and the output forces respectively.

A_i\ \&\ A_o are the input and the output area of pistons respectively.

\frac{F_i\times 4}{\pi.d_i^2} =\frac{F_o\times 4}{\pi.d_o^2}

\frac{F_i}{d_i^2} =\frac{F_o}{d_o^2}

\frac{F_o}{0.04^2}=\frac{F_i}{0.02^2}

F_o=4\times F_i
