Is the rock in the crust able to move around more easily than the rock in the lower mantle.

The product of two consecutive positive integers is greater than their sum by 209.

Akimi4 [234]

Answer: 15 and 16

Explanation:

You can set up an equation N is one positive integer, and N+1 is the second (because they are consecutive, so it's the first number plus one).

Equation to solve for N

N(N+1) = N + (N+1) + 209

N^2 + N = 2N +1 + 209

N^2 - N - 210 = 0 (factor here)

N = 15 or N = -14

Since the question asks for the positive integers, you know the first number is 15, then the next would be 16.

In air, a sound wave with a frequency of 196 hz has a wavelength of about 1.76 meters. what is the wavelength of a wave if the f

Aloiza [94]

The wavelength of the sound wave if the frequency is increased to the given value is 0.44m.

Given the data in the question;

Frequency of sound wave a; $f_a = 196Hz = 196s^{-1}$

Wavelength of sound wave a; $\lambda _a = 1.76m$

Speed of sound wave; $v =\ ?$

Frequency of sound wave b; $f_b = 784Hz = 784s^{-1}$

Wavelength of sound wave b; $\lambda _b = ?$

<h3>Wavelength</h3>

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

It is expressed as;

$\lambda = \frac{v}{f}$

Where v is velocity and f is frequency.

First, we calculate the velocity of the sound wave in air from sound wave a.

$\lambda = \frac{v}{f}\\ \\1.76m= \frac{v}{196s^{-1}}\\\\v = 1.76m * 196s^{-1}\\\\v = 344.96m/s$

Now, we determine the wavelength of sound wave b using the velocity of sound wave in air calculated above.

$\lambda = \frac{v}{f}\\ \\\lambda = \frac{344.96m/s}{784s^{-1}}\\\\\lambda = 0.44m$

Therefore, the wavelength of the sound wave if the frequency is increased to the given value is 0.44m.

An archeologist claimed that he found some gold coins date 46 BC. Do you think this is possible?

almond37 [142]

Answer:

No, I don't.

How could the coins be stamped "46 B.C." when people of that time would have no way of knowing how many years before Christ it was?
