Answer: b) 5

Explanation:

The equation for the temperature in Fahrenheit is:

t = 5h + 61.4  

Where h is the number of hours after 4:00 pm

then if this is compared with a linear equation, the y-intercept is 61.4 Fahrenheit, and the slope is 5 Fahrenheit/hour

Now we want to know by how many degrees Fahrenheit will the temperature rise each hour until 4:00 PM, we need to look at the slope in order to answer this.

We know that the slope is 5 Fahrenheit/hour, so each hour that passes the temperature increases by 5 degrees Fahrenheit.

The right option is b) 5.

Read the article and use the information to answer the following questions. aquatic biomes describe the parts of an ecosystem fo
Nadusha1986 [10]

According to the article, an estuary is a coastal body of water where the mouth of a river meets the sea.

<h3>What are the parts of the ecosystem found in estuaries?</h3>

It is the aquatic biome where a high-flow watercourse empties into the ocean, generally, it is found in areas with high-amplitude tides.

As to the living parts of the ecosystem found in estuaries, a great variety of fish and molluscs are concentrated.

On the other hand, the nonliving things of this ecosystem are low in salinity due to the fact that the sea water, when it meets the river water, loses a large percentage of it, it also offers an ideal temperature for the proliferation of life.

Therefore, we can conclude that according to the article, an estuary is a coastal body of water where the mouth of a river meets the sea.

The surface tension of water in air is approximately 0.00518 lbf/ft. if the atmospheric pressure is 14.7psia, what is the pressu
strojnjashka [21]

Based on the calculations, the pressure inside this droplet is equal to 2,909.35 kPa.

<u>Given the following data:</u>

  • Surface tension = 0.00518 lbf/ft to N/m = 0.00702 N/m.
  • Atmospheric pressure = 14.7psia to kPa = 101.35 kPa.
  • Diameter = 0.01 mm to m = 0.00001 m.

Radius, r = \frac{diamter}{2} =\frac{0.0001}{2} = 0.000005 m.

<h3>How to determine the pressure inside a droplet.</h3>

For a droplet with only one surface, its pressure is given by this formula:

P_1-P_2=\frac{2 \tau}{r} \\\\P_1=\frac{2 \tau}{r}+P_2

Substituting the given parameters into the formula, we have;

P_1=\frac{2 \times 0.00702}{0.000005} + 101.35\\\\P_1=2808+ 101.35

Inside pressure = 2,909.35 kPa.

murzikaleks [220]

During the first hour of this stage, the nurse would assess the woman's fundus every 5 minutes.

<h3>What is Fundus?</h3>

This is referred to the internal structure of a hollow organ such as the uterus in this case. it is usually located at the bottom or the area which is located opposite the aperture of the hollow organ.

It should be checked every 5 minutes to measure the level of contractions and retractions which takes place in the uterus. This is done so as to know the right time for the fetus to be moved to the birth canal during labor of the pregnant female.

The fetus is then expunged to the vagina where the safe delivery of the baby takes place through the help of healthcare or experienced professionals.This is therefore the reason why the fundus should be checked at every 5 minutes interval.
