$\bf \dag \boxed{ \lambda \{ \rm wavelength \} = \dfrac{speed}{frequency} }$

So:-

$\dashrightarrow\lambda \{ \rm wavelength \} = \dfrac{150 \cancel0}{1 \cancel0} \\$

$\\ \\$

$\dashrightarrow\lambda \{ \bf wavelength \} =150m$

Jerimiah is studying Wave A and Wave B. Wave A is traveling at 3 hertz, and Wave B is traveling at 1.2 hertz.

Inga [223]

The prediction about the waves if they were to crash into each other is that The resulting wave would travel at 4.2 hertz.

<h3>What is the wave about?</h3>

Note that:

Constructive interference of the waves is one that leads to an increase in amplitude or frequency of any kind of waves.

Hence:

F' = 3 Hz + 1.2 Hz

= 4.2 Hz

Destructive interference of the waves is one that lowers the amplitude or frequency of waves and as such:

F' = 3 Hz - 1.2Hz = 1.8 Hz

The prediction about the waves if they were to crash into each other is that The resulting wave would travel at 4.2 hertz.

Soon Yi loves to bake, and she is making flaky pastry. Soon Yi starts with a layer of dough 222 millimeters (\text{mm})(mm)left

frozen [14]

Answer:

3 times

Explanation:

When the dough is folded, it increases by a constant factor. We can model the growth of the thickness using the exponential growth model

$T(n)=T_0(1+r)^n$

Where:

Initial thickness, $T_0$ = 2mm

Growth factor, r =8%=0.08

We want to find the smallest number of times Soon Yi will have to roll and fold the dough so that the resulting dough is at least 2.5mm.

i.e When $T(n)\geq 2.5$ mm$

$2(1+0.08)^n\geq 2.5\\2(1.08)^n\geq 2.5\\$Divide both sides by 2$\\\dfrac{2(1.08)^n}{2}\geq \dfrac{2.5}{2}\\\\1.08^n\geq 1.25\\\\$Change to logarithm form\\n \geq \log_{1.08}1.25\\\\n\geq \dfrac{\log 1.25}{\log 1.08} \\\\n\geq 2.9$

Therefore, the smallest number of times Soon Yi will have to roll and fold the dough so that the resulting dough is at least 2.5mm thick is 3.
