Answer:

B. 30m

Explanation:

This is because when a wave interferes constructively with another wave, they will add since constructive relates to joining or building up.

So, 10m + 20m equals a 30m wave.

If the inside of a container has a surface area of 20cm², what will be the pressure on each square inch of the container if 117.

egoroff_w [7]

Answer:

Explanation:

given :-

force applied = 117.6N

Area = 20 m^2

Pressure =?

solution:-

Pressure = Force / Area

= 117.6 N / 20 m^2

= 5.88 Pascals

a car traveling at a velocity of 2 m/s undergoes an acceleration of 4.5 m/s^2 over a distance of 340 m. How fast will it be goin

ra1l [238]

Vi = 2m/s
a= 4.5 m/s
d= 340 m
vf= ?

use this equation ... vf^2=vi<span>^2+2ad

you should get vf = 55.3
hope this helps </span>

Urgent help for a physics exercise!

Zigmanuir [339]

Amplitude of wave is given as maximum displacement from mean position

So here amplitude is 1.25 cm

Wavelength is the length of the wave that it travels in one time period

From graph we can say the wavelength is given as 3cm

PART C)

Time period of wave is the time after which it repeats its shape

Speed of the wave = 21 cm/s

time period = wavelength / speed

$T = \frac{3}{21}$

$T = \frac{1}{7} s$

Now frequency is

$f = \frac{1}{T}$

$f = 7 Hz$

PART D)

Time period = \frac{1}{f}[/tex]

$T = 0.143 s$
