You hear a tone and recognized it to me 512 Hz and you know that the speed of sound

Zigmanuir [339]

Answer:

Explanation:

The frequency equation is

$f=\frac{v}{\lambda}$ where f is frequency measured in Hz, v is velocity of sound measured in m/s and $\lambda$ is wavelength measured in meters. Filling in our given info:

$512=\frac{340}{\lambda}$ and

$\lambda=\frac{340}{512}$ so

$\lambda=.664 m$ (That is the incorrect number of sig dig's by the way. It should only be 2 since the number 340 only has 2 sig dig's)

You are going sledding with your friends, sliding down a snowy hill. Friction can't be ignored. Riding solo on your sled, you ha

Musya8 [376]

If you let a friend ride with you, increasing the mass does increase the net force on the system, but it also increases the inertia. a=Fnetm. Since both the net force and mass are increased they still cancel, leaving the acceleration the same.

<h3>Further explanation </h3>

Inertia is the tendancy of a moving object to keep moving in a straight line or of any object to resist a change in motion.

According to the picture below, we choose x-direction parallel to the inclined surface. Our positive direction is to the right. Hence, we will calculate the acceleration when riding solo first:

$\Sigma F_x = mg sin \theta - F_k = m a_x\\mg sin \theta - F_k = m a_x\\a_x = \frac{mg sin \theta - F_k }{m} ... (1)\\$
