3. A scooter with a mass of 24 kg accelerates at 14 m/s/s when ______ N of force is applied.
wariber [46]

Answer:

<h2>336 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

Force = 24 × 14

We have the final answer as

<h3>336 N</h3>

Hope this helps you

Triangulation is the preferred method of calculation for all astronomical distances.
yan [13]
<span>
if it was possible to triangulate all objects it would give the most accurate answer.  So yes, it is the prefered method.  However as this is not the case other methods are used, less accurate but more practical</span>

Consider a resonator with ω0 = 100 rad/sec and a Q factor of 100. Calculate the time takes it to settle within 2% of the final v
Alla [95]

Answer:

8 s

Explanation:

Damping factor, F is given by

F=\frac {1}{2Q} where Q is quality factor

Also, we know that the settling time, T is given by

T=\frac {4}{FW} where W is the resonant frequency.and substituting the first equation here we get

T= \frac {4\times 2Q}{W}

Since it takes 2% of final value to settle and considering 100 rad/s for resonant frequency and taking quality factor of 100 then  

T=\frac {4\times 2\times 100}{100}= 8 s

calculate the diameter of a silver wire of length 75cm , which is extended by 1.85mm when a 10kg mass is suspended from it's end
sdas [7]

Answer:0.8\ mm

Explanation:

Given

length of wire l=75\ cm

change in length \Delta l=1.85\ mm

mass of wire m=10\ kg

Young's modulus for silver E=7.9\times 10^{10}\ N/m^2

load on wire F=mg

F=10\times 9.8=98\ kg

change in length is given by

\Delta l=\dfrac{Pl}{AE}

Where A=area of cross-section

A=\dfrac{Pl}{\Delta lE}

A=\dfrac{98\times 0.75}{1.85\times 10^{-3}\times 7.9\times 10^{10}}

A=\dfrac{73.5}{14.615\times 10^{7}}

A=5.029\times 10^{-7}\ m^2

also wire is the shape of cylinder so cross-section is given by

A=\dfrac{\pi d^2}{4}=5.029\times 10^{-7}\ m^2

\Rightarrow d^2=\dfrac{5.029\times 10^{-7}\times 4}{\pi }

\Rightarrow d^2=64.02\times 10^{-8}

\Rightarrow d=8\times 10^{-4}\ m

\Rightarrow d=0.8\ mm
