A quarterback throws a football with angle of elevation 40 and speed 60 ft/s/ find the horizontal and vertical components of the

velocity vector

BARSIC [14]4 years ago
6 0
If we imagined the velocity vector as the hypotenuse of a right angles triangle, therefore,

The horizontal component will be the adjacent side <span>of 60 ft/sec with an adjacent angle of 40</span> degrees.
horizontal component = <span> 60 x cos40 = 45.9626 ft/sec

The vertical component will be the opposite side </span>of 60 ft/sec with an adjacent angle of 40 degrees.
vertical component = 60 x sin40 = 38.5672 ft/sec

Reactance Frequency Dependence: Sketch a graph of the frequency dependence of a resistor, capacitor, and inductor. RLC Circuit R
jolli1 [7]

Answer:

f=\frac{1}{2\pi \sqrt{LC}}

Explanation:

We know that impedance of a RLC circuit is given by Z=R+J(X_L-X_C)

So Z=\sqrt{R^2+(X_L-X_C)^2} here R is resistance X_L is inductive reactance and X_C is capacitive reactance

To minimize the impedance X_L-X_C should be zero we know that X_L=\omega L\ and \ X_C=\frac{1}{\omega C}

So \omega L-\frac{1}{\omega C}=0

\omega ^2=\frac{1}{LC}

\omega =\sqrt{\frac{1}{LC}}

We know that \omega =2\pi f

So \omega =2\pi f=\frac{1}{\sqrt{LC}}

f=\frac{1}{2\pi \sqrt{LC}}

Where f is resonance frequency

If a total of 1250 offspring were obtained from your cross, determine the number of offspring that you would expect to obtain th
irakobra [83]

Answer:

106 single crossover events

Explanation:

Total number of offspring = 1250

<u>Determine the number of offspring that would be expected </u>

( Rf between the genes vg and Pr ) * ( Total number of progeny )

  =   0.125 * 1250 ≈ 156 ( value for single and double crossovers )

next :

( value of the Rf of double crossovers ) * ( Total number of progeny )

= (0.322 * 0.125) = 0.04025  * 1250 = 50

Hence the number of offspring expected to obtain/represent a single crossover event between pr and vg

=  156 - 50 =  106
