tankabanditka [31]

Answer:

V_{A/E}=55.23km/h\\or\\V_{A/E}=15.342m/s

Explanation:

The velocity of plane relative to earth is given by:

V_{P/E}=\frac{d}{t}\\V_{P/E}=\frac{[-121i-20j]km}{0.490h}  \\V_{P/E}=[-247i-41j]km/h

As the from given data.The velocity of plane relative to air is:

V_{P/A}=[-210i]km/h

According to relative motion of velocity of the air relative to earth given by:

V_{A/E}=V_{P/E}-V_{P/A} \\V_{A/E}=[(-247i-41j)km/h]-(-210i)km/h\\V_{A/E}=[-37i-41j]km/h\\

The magnitude is given as:

V_{A/E}=\sqrt{(37)^{2}+(41)^{2}  }\\ V_{A/E}=55.23km/h\\or\\V_{A/E}=15.342m/s

A Yugo can accelerate from rest to a speed of 28 m/s in 20 s. What is the average acceleration of the car? What distance does it
harina [27]

Answer:

Explanation:

a=28/20

a=1.4 m/s²

V²=v0²+2a.D

28²=0+2x1.4D

784 = 2.8D

D = 280 m

Find the intensity of a 55 dB sound given I 0=10^-12W/m^2
MakcuM [25]

Answer:

3.16 × 10^{-7} W/m^{2}

Explanation:

β(dB)=10 × log_{10}(\frac{I}{I_{0} })

I_{0}=10^{-12} W/m^{2}

β=55 dB

Therefore plugging into the equation the values,

55=10 log_{10}(\frac{I}{ [tex]10^{-12}})[/tex]

5.5= log_{10}(\frac{I}{ [tex]10^{-12}})[/tex]

10^{5.5}= \frac{I}{10^{-12} }

316227.76×10^{-12}= I

I= 3.16 × 10^{-7} W/m^{2}
