Answer:
use the formula
Explanation:
F = 1/ T
where F stands for frequency and T stands for period
sub in 3 Hz into frequency
3 = 1/T
0.333 = T
or in a fraction form
1/ 3

The horizontal distance traveled below the table's edge is 29.4 cm.
The given parameters;
- <em>mass of the bullet, = 15 g = 0.015 kg</em>
- <em>speed of the bullet, = 630 m/s</em>
- <em>mass of the block, = 4.9 kg</em>
The final velocity of the bullet-block system is calculated as follows;
The time for the bullet-block system to reach the ground from the table is calculated as follows;
The horizontal distance traveled below the table's edge is calculated as follows;
Thus, the horizontal distance traveled below the table's edge is 29.4 cm.

<span>C) Pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particles.
Let's look at the available choices and determine why or why not they're correct.
A) Pressure will expand a gas, enlarging its volume and reducing its density and concentration of particles.
* What? So increasing the pressure on a gas will make it take up a larger volume? That definitely doesn't match the world I live in. I hope that's true for you as well. Wrong choice.
B) Pressure will magnify a gas, developing its volume and multiplying its density and concentration of particles.
* Lots of interesting sounding words, but they're mostly used in a nonsense fashion. Useful if you're easily fooled by technobabble, but it's another wrong answer.
C) Pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particles.
* OK. Increasing the pressure will compress a gas. So it has a smaller volume. And since it still has the same mass, the density will become greater. And the particles closer together. Everything here matches reality. Good choice.
D) Pressure will accelerate a gas, extending its volume and allowing a smaller density and concentration of particles.
* Most technobabble. Why would the gas be accelerated? No reason that I know of. Wrong choice.</span>
The distance is the total distance she walked which is 16 meters adding the 6 meters to the corner and 10 meters to her friend's apartment. Her displacement is the distance from her original starting point so you set up a triangle with side lengths of 6 and 10 and solve for the hypotenuse which gives you a displacement of 11.66 meters.
Answer:
The image of everything in front of the mirror is reflected backward, retracing the path it traveled to get there. Nothing is switching left to right or up-down. Instead, it's being inverted front to back. ... That reflection represents the photons of light, bouncing back in the same direction from which they came
