Explanation:
The given data is as follows.
Velocity of bullet, 
= 814.8 m/s
Observer distance from marksman, d = 24.7 m
Let us assume that time necessary for report of rifle to reach the observer is t and will be calculated as follows.
t = 
(velocity in air = 343 m/s)
= 0.072 sec
Now, before the observer hears the report the distance traveled by the bullet is as follows.
= 
= 58.66
= 59 (approx)
Thus, we can conclude that each bullet will travel a distance of 59 m.
Answer:
I believe the answer is Bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons.
Explanation:
valence electrons are the outermost shell, so when you go through keeping that in mind it helps you find the right answer
B
paired electrons spin in opposite directions cancelling their magnetic fields
Answer:
A. velocity and wavelength
Explanation:
- When a wave travels from one medium to another it undergoes a change in direction and this is referred to as refraction.
- Refraction is the bending of a wave or a change in direction of a wave as it travels from one medium to another. Refraction is accompanied by change in velocity and wavelength of a wave.
- Velocity of a wave is proportional to the wavelength of the wave therefore, if the velocity of a wave changes the the wavelength will also change proportionally to the velocity.
Answer:
Distance piston B = 3 [in]
Explanation:
This problem can be solved using the pascal principle, which is applied for both pressures and volumes. In this case we use the definition of volumes, which says that the volume displaced fluid on one side of the Pistons should be equal to the volume displaced on the other side of the piston.
We know that the volume is equal to the product of an area by a length
![V_{A}=V_{B}\\A_{A}*d_{A}=A_{B}*d_{B}\\2*6=4*d_{B}\\d_{B}=12/4\\d_{B}=3[in]](https://tex.z-dn.net/?f=V_%7BA%7D%3DV_%7BB%7D%5C%5CA_%7BA%7D%2Ad_%7BA%7D%3DA_%7BB%7D%2Ad_%7BB%7D%5C%5C2%2A6%3D4%2Ad_%7BB%7D%5C%5Cd_%7BB%7D%3D12%2F4%5C%5Cd_%7BB%7D%3D3%5Bin%5D)
