Answer:
It travels 1414 feets.
Explanation:
Let's take the length the bullet travels <em>l </em>as the hypotenuse of a right triangle and the height it reaches one of its sides. Since we got the angle α at which it was fired and the height <em>h</em> it reached, we can calculate <em>l</em> using the <em>sin(α)</em> function:
![sin(\alpha )=\frac{opposite side}{hypotenuse}\\sin(\alpha)=\frac{h}{l}\\l=\frac{h}{sin(\alpha)}](https://tex.z-dn.net/?f=sin%28%5Calpha%20%29%3D%5Cfrac%7Bopposite%20side%7D%7Bhypotenuse%7D%5C%5Csin%28%5Calpha%29%3D%5Cfrac%7Bh%7D%7Bl%7D%5C%5Cl%3D%5Cfrac%7Bh%7D%7Bsin%28%5Calpha%29%7D)
Replacing:
![l=\frac{1000ft}{sin(\frac{\pi}{4})}](https://tex.z-dn.net/?f=l%3D%5Cfrac%7B1000ft%7D%7Bsin%28%5Cfrac%7B%5Cpi%7D%7B4%7D%29%7D)
Solving and roundin to the nearest foot:

Answer:
Cuanto más fuerte es el ácido, más rápido se disocia para generar H +start superscript, plus, end superscript. Por ejemplo, el ácido clorhídrico (HCl) se disocia completamente en iones hidrógeno y cloruro cuando se mezcla con agua, por lo que se considera un ácido fuerte.
Beats are interference patterns between two tones of different frequencies. To prove the skeptic first, play the recorded audio as there are no beats in it. Now take two sound sources with different frequencies. When both sources are turned on, we hear notes that rise and fall at equal intervals. That's what's called beats.
A frequency beat occurs when two waves with different frequencies overlap, causing alternating cycles of constructive and destructive interference between the waves.
When we tap the table with our finger, then put our ear to the table, and tap the table surface as far as 30 cm from our ear. Then the sound of beats on the table will sound louder when we put our ears on the table. So, it can be concluded that solid objects can conduct sound better than air. This is because the molecules or particles of solid objects are denser than air.

Answer:1.04 N
Explanation:
Given
Gravitational Force on the Platter is ![5 N](https://tex.z-dn.net/?f=5%20N)
Tray makes an angle of ![\theta =12^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%20%3D12%5E%7B%5Ccirc%7D)
This gravitational Force has components along and Perpendicular to Platter
Perpendicular Force ![W_p=W\cos \theta](https://tex.z-dn.net/?f=W_p%3DW%5Ccos%20%5Ctheta%20)
![W_p=5\times \cos 12=4.89 N](https://tex.z-dn.net/?f=W_p%3D5%5Ctimes%20%5Ccos%2012%3D4.89%20N)
Along the Tray
![W_{along}=W\sin \theta](https://tex.z-dn.net/?f=W_%7Balong%7D%3DW%5Csin%20%5Ctheta%20)
![W_{along}=5\times \sin 12=1.04 N](https://tex.z-dn.net/?f=W_%7Balong%7D%3D5%5Ctimes%20%5Csin%2012%3D1.04%20N)
Thus 1.04 N is the magnitude of force that will cause Platter to slide down
