Answers
Answer: a buret
A graduated cylinder and a beaker cannot be used. This is because the basic solution needs to be added drop by drop. This is not possible using a graduated cylinder or a beaker because it is difficult to pour drop by drop from these. An eye dropper cannot be used because it does not measure the volume being added.
A buret would be the best choice because it precisely measures the amount being added and we can add the basic solution to the acid drop by drop.

Answer:
The John 's speed is 20 m/s.
The Betty's speed is 20 m/s
Explanation:
Given that,
John is traveling north at 20 meters/second and his friend Betty is traveling south at 20 meters/second.
We need to calculate the John and Betty's speeds
We know that,
The speed is a scalar quantity. its has only magnitude.
Hence, The John 's speed is 20 m/s.
The Betty's speed is 20 m/s
Direction is not involved in describing speed.

The pellets in a shotshell start to spread or scatter as soon as they are fired. This dispersion will increase as the pellets travel farther. Shotgun barrels feature a choke to regulate this pellet pattern. The shotgun barrel's choke is the constriction at the muzzle end.
How long is a shot string?
At 20 yards, it can be roughly 5 feet long, and at 30 yards, it can be 8 feet long. The variance is brought on by the pellets' distortion as they move along the barrel.
The full choke features the tightest shot pattern and is the tightest choke. The pellets are kept together for a longer distance thanks to this choke. It is typically used for shots that are further than 40 yards.

Answer:
The stopping distance for the car when the driver slams on her brakes is 7.38 m.
Explanation:
The distance traveled for the car after stopping can be found using the following equation:
Where:
vf is the final speed = 0 (it stops)
v₀ is the initial speed = 11 m/s
a is the acceleration = -8.2 m/s²
d is the distance =?
When the driver slams on her brakes the distance traveled is:
Therefore, the stopping distance for the car when the driver slams on her brakes is 7.38 m.

Answer:
They will interfere to create a crest with an amplitude of 2.
Explanation:
If the crest of one wave meets the trough of another wave, destructive interference occurs and the combined amplitude will be less than that of either wave alone. If the amplitudes of the two waves are equal, when the crest and trough superimpose, the combined amplitude will be zero.
