<h2>Answer: decreases</h2>

The speed v of a wave is given by the following formula:

v=f.\lambda   (1)

Where:

f the frequency  of the wave

\lambda the wavelength

But, we want to know<u> its wavelength</u>, hence we have to rewrite equation (1):

\lambda=\frac{v}{f}   (2)

If we are told the wave is passing through a uniform medium, this means <u>its velocity is constant</u> in this medium.

So, keeping this in mind, from (2) we are able to know that \lambda is inversely proportional to f.

What does this mean?

If f increases \lambda decreases

and

If f decreases  \lambda increases

Therefore the correct option is b:

<h2>As the frequency of this wave increases, its wavelength <u>decreases</u>.</h2><h2 />

B. Decreases

Why: Because the longer the wavelength the lower the frquency. The shorter the wavelength the higher the frequency.

Answer:

455,000 Pa

Explanation:

PV = nRT

If n is constant:

PV / T = PV / T

(101,325 Pa) (718 mL) / (273 K) = P (175 mL) / (26 + 273) K

P = 455,000 Pa

If a wave’s frequency is 16Hz and it’s wavelength is 10m. What’s the waves speed?
Vesna [10]

Answer:

160J

Explanation:

Given parameters:

Frequency  = 16Hz

Wavelength = 10m

Unknown:

Waves speed  = ?

Solution:

Waves speed is the product of frequency and wavelength;

  Waves speed  = fλ

f is the frequency

λ is the wavelength

Now insert the parameters and solve;

     Waves speed = 16 x 10  = 160J

Particles q1, q2, and q3 are in a straight line.
natima [27]

The net force on q2 will be 1.35 N

A force in physics is an effect that has the power to alter an object's motion. A mass-containing object's velocity can vary, or accelerate, as a result of a force. Intuitively, a push or a pull can also be used to describe force. Being a vector quantity, a force has both magnitude and direction.

Given Particles q1, q2, and q3 are in a straight line. Particles q1 = -5.00 x 10-6 C,q2 = +2.50 x 10-6 C, and q3 = -2.50 x 10-6 C. Particles q₁ and q2 are separated by 0.500 m. Particles q2 and q3 are separated by 0.250 m.

We have to find the net force on q2

At first we will find Force due to q1

F = 9 × 10⁹ × 5 × 10⁻⁶ × 2.5 × 10⁻⁶ / 0.5²

F = 450 × 10⁻³

F₁ = 0.45 N (+)

Now we will find Force due to q2

F = 9 × 10⁹ × 5 × 10⁻⁶ × 2.5 × 10⁻⁶ / 0.25²

F = 1800 × 10⁻³

F₂ = 1.8 N (-)

So net force (F) will be

F = F₂ - F₁

F = 1.8 - 0.45

F = 1.35 N

Hence the net force on q2 will be 1.35 N
