Answer: The angle of refraction is 32°

Explanation:

By snell law, we have that:

n₁*sen(θ₁) = n₂*sen(θ₂)

Where n₁ = 1.5

n₂ = 2.0

θ₁ = 45°.

then we want to find the angle of refraction.

1.5*sin(45°) = 2*sin(x)

x = Asin(1.5*sin(45°)/2) = 32°

After prostate surgery a client’s indwelling catheter and continuous bladder irrigation (CBI) are to be removed. The nurse discu
Verizon [17]

Answer:

The options

1

Have dilute urine."

2

Be unable to urinate."

3

Produce dark red urine."

4

Experience some burning on urination."

The CORRECT ANSWER IS 4

4

Experience some burning on urination."

Explanation:

Due to the trauma affecting the mucous membranes of the urinary tract, burning on urination is a more likely response, this sensation gets to reduce with time. This will stop the urine from further dilution once the frequent continuous bladder irrigation is stoped and removed. Although, the urine may show a slight pink tinge which results from the trauma after the surgery and the effect of the catheter that is noticed. A difficulty to urinate won't be felt except the indwelling catheter is removed earlier than it should expected and edema still occurs in the urethra. Production of dark red urine is an indicative factor for hemorrhage, which ought not to be seen.

black coffee has a pH of 5, therefore its H+ concentration is ______ times greater than a solution with a pH of 10.
Tju [1.3M]

Answer:

100,000

Explanation:

pH of coffee = 5

pH of solution = 10

Concentration of H+ ions between successive pH values are in multiples of 10

Hence, the pH difference :

pH of solution - pH of coffee

(10 - 5) = 5

Hence, difference in H+ ions will be :

10^5 = 10*10*10*10*10 = 100,000 times

Based on the information in the graph, which blood type is most likely to be in shortest supply during an emergency?
Maksim231197 [3]
While there is no graph provided and I cannot find the graph online, I will base my answer through theory. 

In theory, the most common blood type is O+, followed by A+, then B+, then AB+. Rh negative blood is deemed to be rare. While the most common blood type is O+, the same blood type is also called the "universal donor" as a type O+ blood has no antigens attached in red blood cells therefore the probability of adverse reactions (i.e. hemolytic reactions) when transfused to other blood types are close to nil. In an emergency situation, wherein there is not enough time to do proper crossmatching, blood type O+ can be used therefore supplies of blood type O+ are easily depleted.
