Answer:

Exercise 1;

The centripetal acceleration is approximately 94.52 m/s²

Explanation:

1) The given parameters are;

The diameter of the circle = 8 cm = 0.08 m

The radius of the circle = Diameter/2 = 0.08/2 = 0.04 m

The speed of motion = 7 km/h = 1.944444 m/s

The centripetal acceleration = v²/r = 1.944444²/0.04 ≈ 94.52 m/s²

The centripetal acceleration ≈ 94.52 m/s²

One small speaker is placed 3m to the east of a second speaker, and a listener stands 4m directly south of one of the speakers.

Answer:

The value is $\lambda = 2 \ m$

Explanation:

From the question we are told that

The distance of the speaker from the second speaker to the east is $d = 3 \ m$

The distance of the speaker from the listener to the south is $a = 4 \ m$

Generally given that if the speaker move in any direction, their sound become louder , it then mean that the position of the listener of minimum sound (i.e a position of minima ) ,

Generally the path difference of the sound produce by both speaker at a position of minima is mathematically represented as

$y = \frac{\lambda}{2}$

Generally considering the orientation of the speakers and applying Pythagoras theorem we see that distance from the second speaker to the listener is mathematically represented as

$b = \sqrt{d^ 2 + a^2 }$

=> $b = \sqrt{3^ 2 + 4^2 }$

=> $b = 5$

Generally the path difference between the two speaker with respect to the listener is

$y = b - a$

=> $y = 5 - 4$

=> $y = 1$

$1 = \frac{\lambda}{2}$

=> $\lambda = 2 \ m$

Which statement describes why scientific notation is useful? It makes very small numbers into whole numbers. It converts fractio

disa [49]

It makes calculations with very large and small numbers easier.

Scientific notation is a system used in order to It makes calculations with very large and small numbers easier. It is useful as it allows very large number that would take a lot of space to write otherwise, and it allows them to be calculated easier. $10^{23}$ for example is a incredible large number, but written in this form is immediately understandable and useful for calculation.
