Answer:

Answer 740 H z, 1110 H z, 1480 H z

Explanation:

The F sharp note (370 Hz) makes the next three harmonics with frequencies of 740 Hz, 1110 Hz, and 1480 Hz, respectively.

It is necessary to have an understanding of the relationship between harmonics and the fundamental frequency in order to calculate the frequencies of the following three harmonics produced by the note F sharp, which has a pitch of 370 Hz.

The fundamental frequency, denoted by f1, is the first harmonic and corresponds to the frequency of the note (F sharp in this example) when it was initially played. Its pitch is 370 hertz.

The fundamental frequency (f1) is multiplied by two to get the second harmonic frequency (f₂), which is written as f₂ = 2 × f1.

The frequency of the third harmonic (f₃) is equal to three times the frequency of the fundamental tone, or f₃ = 3 × f₁.

The frequency of the fourth harmonic, denoted by f₄, is equal to four times the frequency of the fundamental tone. f₄ = 4 × f₁

If we know that the fundamental frequency, or f₁, is 370 hertz, then we can figure out the frequencies of the following three harmonics, which are as follows:

f₂ = 2 × 370 Hz, which equals 740 Hz

f₃ = 3 times 370 Hz, which equals 1110 Hz; f₄ = 4 times 370 Hz, which equals 1480 Hz

Following the frequency of the F sharp note (370 Hz), the next three harmonics produced have frequencies of 740 Hz, 1110 Hz, and 1480 Hz respectively.

The forces of attraction between water molecules and the glass walls and within the molecules of water themselves are what enable the water to rise in a thin tube immersed in water.

Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body.

Force is defined as the product of mass and acceleration. Its unit is Newton.

Surface or interfacial forces lead to capillarity. The forces of attraction between the water molecules and the glass walls and among the water molecules themselves are what causes the water in a thin tube submerged in water to rise.

Taking into account the definition of density, the volume of the metal block is 3 m³.

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

In this case, you know that:

Replacing in the definition of density:

[tex]5000 \frac{kg}{m^{3} } =\frac{15000 kg}{volume}[/tex]

Solving:

volume×5000 [tex]\frac{kg}{m^{3} }[/tex]= 15000 kg

volume= [tex]\frac{15000 kg}{5000 \frac{kg}{m^{3} }}[/tex]

Explanation:

3 minutes = 180 seconds

v f = at  =  .5 m/s^2 * 180 s = 90 m/s

Distance =  1/2 a t^2 = .5 * .5 * 180^2 = 8100 m

Answer:

See below

Explanation:

vertical velocity=13.9 sin 25

When it hits the ground  y = 0

0 = vo t - 1/2 a t^2

0    =  13.9 sin 25  t   - 1/2 (9.81)t^2  

0 = 13.9 sin 25 - 1/2 (9.81) t        shows t = 1.1976  ~ 1.2 sec

horizontal speed x time = distance

13.9 cos 25   x   1.1976 =15 .1 meters    

The answer to the question is 1.125  Newton

Formula for electrostatic force is F = ( K q1 q2 )/ r²

where q1 and q2 represent the charges and r represents the distance between them and the value of K is 9 × 10⁹.

Total net force on q3 will be the summation of electrostatic force between q1 and q3 and electrostatic force between q2 and q3, as all the three charges are of same sign and lie in the same line.

Electrostatic force between q1 and q3

r will be 0.500 + 0.500 = 1 m

F = ( K q1 q3 )/ r²

F = ( (9 × 10⁹ ) x (5.00 x 10⁻⁶) x (5.00 x 10⁻⁶) )/ 1²

F₁₃ = 2.25  × 10⁻¹ N

Electrostatic force between q2 and q3

r will be 0.500 m

F = ( K q1 q3 )/ r²

F = ( (9 × 10⁹ ) x (5.00 x 10⁻⁶) x (5.00 x 10⁻⁶) )/ 0.5²

F = (225 × 10⁻³) / (25 × 10⁻²)

F₂₃ = 9 × 10⁻¹ N

Total force on q3 will be F₁₃ + F₂₃

Total force on q3 =  ( 2.25  × 10⁻¹ ) + (9 × 10⁻¹ ) N

Total force on q3 =  ( 2.25  × 10⁻¹ ) + (9 × 10⁻¹ ) N

Total force on q3 =  ( 11.25  × 10⁻¹ ) N

Total force on q3 =  1.125  N
