what is the wavelength of radio waves transmitted by an FM station at 90MHz where 1M=10^6, and speed of radiowave is 3*10^8m/s
Igoryamba

Answer:

λ = 3.33 m

Explanation:

<u><em>Given:</em></u>

Frequency = f = 9 × 10⁷ Hz

Speed = v = 3 × 10⁸ m/s

<u><em>Required:</em></u>

Wavelength = λ = ?

<u><em>Formula:</em></u>

v = fλ

<u><em>Solution:</em></u>

<em>Putting the givens in the formula</em>

v = fλ

λ = \frac{v}{f}

λ = \frac{3*10^8}{9*10^7}

λ = 0.33 × 10¹

λ = 3.33 m

Refer to the image. Calculate the magnitude of change in velocity of the cue ball.
valkas [14]

Answer:

If you add the 2 velocity vectors you get the velocity of the third vector which is the (change in) velocity of the cue ball after striking the cushion

PolarNik [594]

Answer:

(a) a = - 201.8 m/s²

(b) s = 197.77 m

Explanation:

(a)

The acceleration can be found by using 1st equation of motion:

Vf = Vi + at

a = (Vf - Vi)/t

where,

a = acceleration = ?

Vf = Final Velocity = 0 m/s (Since it is finally brought to rest)

Vi = Initial Velocity = (632 mi/h)(1609.34 m/ 1 mi)(1 h/ 3600 s) = 282.53 m/s

t = time = 1.4 s

Therefore,

a = (0 m/s - 282.53 m/s)/1.4 s

<u>a = - 201.8 m/s²</u>

<u></u>

(b)

For the distance traveled, we can use 2nd equation of motion:

s = Vi t + (0.5)at²

where,

s = distance traveled = ?

Therefore,

s = (282.53 m/s)(1.4 s) + (0.5)(- 201.8 m/s²)(1.4 s)²

s = 395.54 m - 197.77 m

<u>s = 197.77 m</u>
