Which is greater 10 newtons or 5 pounds

1 answer:

6 0

On Earth, 1 kilogram of mass weighs 9.8 newtons or 2.2 pounds.

9.8 newtons = 2.2 pounds

(9.8/2.2) newtons = 1 pound = 4.45 newtons

   (2.2/9.8) pounds = 1 newton = 0.225 pound

5 pounds = (5 x 4.45 newtons) = 22.2 newtons.

    22.2 newtons is more than 10 newtons, so
   5 pounds is more than 10 newtons.

A violin string has a length of 327mm and produces a note of frequency 440Hz.

Scorpion4ik [409]

The characteristics of the standing wave we can find the backlash for the frequency of the wave when the string is shortened is:

The new frequency is f = 657 Hz

<h3>How is a standing wave produced?</h3>

A standing wave is produced when a traveling wave meets an obstacle and bounces, the sum of the two waves results in a wave that does not propagate in space.

In the event that the obstacle is a fixed point, there is a node at this point. The expression for the length of the standing wave.

L = $\frac{\lambda }{2}$ fundamental frequency

L = $2 \frac{\lambda}{2}$ second harmonic

L = $3 \frac{\lambda}{2}$ third harmonic

L = $n \frac{\lambda}{2}$ general term.

Where L is the length of the chord, lan the wavelength and n an integer.

Wave speed is related to wavelength and frequency.

v = λ f.

Let's substitute.

v = $\frac{2L}{n}$

They indicate that initially the string has a length of L₀ = 327 mm= 0.327m and the frequency is f₀ = 440 Hz.

v n = 2L₀ f₀

v n = 2 0.327 440

v n = 287.76

They indicate that the tension on the string do not changes and the speed of the wave depends only on the tension and the density of the string, therefore it is constant, we assume that the harmonic does not change either, therefore the new length.

v n = 2 L f

Let's substitute.

287.76 = 2 L f

f = $\frac{287.76x}{2L}$

Let's calculate.

f = $\frac{287.76}{2 \ 0.219}$

f = 656.99 Hz

In conclusion with the characteristics of the standing wave we can find the backlash for the frequency of the wave when the string is shortened is:

The new frequency is: f = 657 Hz

Which type of force can be in the same it opposite direction?

LuckyWell [14K]

Answer:

C) unbalanced

Explanation:

Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object's motion. When you add equal forces in opposite direction, the net force is zero.
