Two tuning forks of frequency 480 hz and 484 hz are struck simultaneously. what is the beat frequency resulting from the two sou

umka21 [38]

Ans: Beat frequency = $f_b$ = 4Hz

Explanation:
The beat frequency is equal to the absolute value of the difference in frequency of the two waves. In other words, the number of beats per second is equal to the difference in frequency. It is due to the destructive and constructive interference. <span>According to this interference, sound will be soft or loud.

Hence. the formula is:
</span>Beat frequency = $f_b = |f_2 - f_1|$
<span>
Since,
</span> $f_1 = 480Hz$
$f_2 = 484Hz$

Therefore,
Beat frequency = $f_b = |484 - 480|$

=> Beat frequency = $f_b = 4Hz$

You drive a car east on the highway at 26 m/s. Another car passes you moving east traveling at 32 m/s. How fast do you view the

tamaranim1 [39]

The speed of the car passing you is 6 m/s while car is moving 6 m/s behind the car.

<h3>Relative velocity of the car</h3>

The speed of the car passing you is determined by applying relative velocity principle as shown below;

Vr = Va - Vb

Vr = 26 m/s - 32 m/s

Vr = -6 m/s

Thus, the speed of the car passing you is 6 m/s while car is moving 6 m/s behind the car.

Your car is stalled in the middle of a large patch of ice (assumed to be frictionless). You have a friend that has thrown a rope

Gnoma [55]

Answer:

The time depends on the distance that they have to travel

$x(t) = \frac{0.3846t^{2} }{2}$

Explanation:

The only horizontal force exerts over the car and you, it is the force that your friend is applied

Newton's Second Law of Motion defines the relationship between acceleration, force, and mass, thus

$\sum{F} = ma$

550 = 1430a

a = 0.3846 m/s2

The car and you have a motion under constant acceleration, then theirs position to a time-based is:

$x(t) = x_{0} + v_{0}t +\frac{at^{2} }{2}$

By the initial conditions

$x(t) = \frac{at^{2} }{2}$

$x(t) = \frac{0.3846t^{2} }{2}$

The time depends on the distance that they have to travel
