At that time, we still haven't developed the technology to measure blood alcohol content by using breathalyser.
Because of this, the only method that can be done to measure the alcohol level in the driver's blood is by asking the doctor to draw the blood and examine it in lab.
Answer:
Apart from the racial identity of victims, the victim's alleged sexual conduct typically triggered the lynch violence of southern white mobs.
Explanation:
Closing a straw's mouth with a finger traps air inside, creating lower pressure than the external atmospheric pressure. This pressure difference prevents water from spilling out by balancing the forces of gravity and atmospheric pressure, maintaining equilibrium within the straw.
When a straw's mouth is closed with a finger, a crucial principle of fluid dynamics comes into play: air pressure. Inside the straw, there is both water and air. Gravity tends to pull the water down, trying to empty the straw. However, when the mouth is closed, the air inside creates a barrier against the downward pull of gravity.
The pressure inside the straw is now lower than the atmospheric pressure outside. This atmospheric pressure pushes down on the water's surface outside the straw, effectively balancing the gravitational force trying to make the water spill out.
In simple terms, the combination of the finger closing the straw's mouth and the external atmospheric pressure prevents the water from spilling out. The pressure difference inside and outside the straw maintains equilibrium, counteracting the force of gravity.
In conclusion, closing the straw's mouth with a finger creates a pressure difference that prevents the water from spilling out due to the balance between atmospheric pressure and gravity.

Water does not spill out from a straw when its mouth is closed with a finger because the closed system created by the airtight seal prevents air from entering the straw. This allows the water to remain inside without spilling out.
When the mouth of a straw is closed with a finger, it creates an airtight seal. This seal prevents air from entering the straw and allows the water to remain inside without spilling out. The principle behind this is Pascal's law, which states that when pressure is applied to a fluid in a confined space, the pressure is transmitted equally in all directions.
In this case, when the finger closes the mouth of the straw, it creates a closed system. The pressure exerted by the finger on the mouth of the straw is transmitted through the water inside the straw, causing the water to push against the finger and maintain its position inside the straw.

Answer:
You will get the product of two times itself of the original binomial
Explanation:
square is multiplying something by itself two times.
So when you square a binomial you will get two times itself as the answer
