Question 4 (1 point)

Physics
1 answer:
irina1246 [14]2 years ago
3 0

Answer:

B

Explanation:

v=349m/s

d=vt

d=349*3

d=1047m

WHY 349??

Because, velocity of sound increases about 0.6 m/s for every 1 degree celsius rise in temp.

Velocity of sound is about 343 m/s at 20 degrees C, so 0.6*10=6 more m/s, or 349 m/s. Kinda cool how temperature alters the speed of sound!

Which tuning forks will give rise to a beat frequency of 20 Hz when sounded together with a 240 Hz tuning fork?
Lubov Fominskaja [6]

Use the concept of beat frequency to find the applicable final freqeuncy for 20Hz beat frequency.

Beat can be defined as 'the interference pattern between two sounds of slightly different frequencies0

The expression for beat frequency is given as

f_{beat} = |f_1-f_2|

Where,

f_2 = Final frequency

f_1 = Initial frequency

The beat frequency for us is 25Hz and the initial frequency is 240Hz, then

20= |f_2-240|

Being an absolute value, two values are possible, both in addition and subtraction:

f_2 = 240 \pm 20

The two possible values are

f_2 = 220Hz

f_2 = 260Hz

Find the y-component of this
Alborosie

Answer:

-0.0789 m

Explanation:

Recall that the y-component comes associated with the sin(18.4) through the following trigonometric relationship:

y = 0.250 sin(-18.4) ≈ -0.0789 m

Notice it is negative since it is below the x-axis.
