A rabbit runs across a parking lot The coordinates of the rabbit as a function of the time t x =-0.3t^2+7.2t+28 and y = 0.22 +² - 9.1t+ 30 with t in secs and x in metres At t=15s, what is the rabbit's position vector r in unit vector notation and as a magnitude angle​

Answers

Answer 1

Rabbit's position vector (r) in the unit vector is 203.5î - 57j and the magnitude and directional angle of vector (r) are 195.35m and 0.004° respectively.

Given

x = 0.3t² + 7.2t + 28

y = 0.22t² - 9.1t +30

At t = 15s

x = 0.3(15)² + 7.2(15) +28 = 203.5

y = 0.22(15)² - 9.1(15) + 30 = -57

The rabbit's position vector (r) in unit vector notation is:

r = 203.5î - 57j

The magnitude of position vector (r)

r = √x² + y²

r = √(203.5)² - (57)² =√38163.25

  =  195.35m

The directional angle of position vector (r)

tanθ = y/x = -57/203.5

θ = [tex]tan^{-1}[/tex] (-57/203.5)

θ = 0.004°

Hence, rabbit's position vector (r) in the unit vector is 203.5î - 57j and the magnitude and directional angle of vector (r) are 195.35m and 0.004° respectively.

1. What causes morning sickness?
2. How long can Kim expect to have symptoms related to morning sickness?
3. What vitamins can she take to reduce the symptoms?
4. Is having a low-birth-weight baby likely to occur from common morning sickness?

Answers

Answer:

........................................

There’s no one cause of morning sickness during pregnancy, and severity varies among women. Increased hormone levels during the first few weeks of pregnancy is among the most common causes. Reduced blood sugar is another common cause of morning sickness.

Other factors can worsen morning sickness. These include:

having twins or triplets
excessive fatigue
emotional stress
frequent traveling
Morning sickness can vary between pregnancies. While you may have had severe morning sickness during one pregnancy, in future pregnancies it may be very mild.
had severe morning sickness during one pregnancy, in future pregnancies it may be very mild.

If you’re in the middle of this, you can probably attest to the fact that morning sickness definitely doesn’t just happen in the morning. Some people are sick all day, while others struggle in the afternoon or evening.

The term morning sickness comes from the fact that you might wake up queasier than usual after going the whole night without eating. But just 1.8 percent of pregnant women have sickness only in the morning, according to this study from 2000. Some medical professionals have started to refer to the group of symptoms as NVP, or nausea and vomiting during pregnancy.

If you’ve found yourself in the unfortunate group of people who have nausea all day, you’re not alone — and again, symptoms should let up as the first trimester concludes.

Vitamin k and vitamin c taken together may provide relief of morning sickness symptoms of some women.

Women with a severe form of morning sickness who take antihistamines to help them sleep through their debilitating nausea are significantly more likely to experience adverse pregnancy outcomes, including low birth weight babies and premature births

You are caring for ER, a 28 year old female. She and her husband were having breakfast when she suddenly stopped responding to him. Her husband states, "She just stared into space and kept saying, ‘It’s like this, it’s like this, it’s like this.’" When her husband put his hand on her arm, she hit him. He called 911 and they are now in the emergency department and she is being evaluated for seizure disorder.

Required:
a. What kind of seizure might ER have had? Explain your answer.
b. What assessments and diagnostics will be used to rule seizure disorder in or out?
c. ER’s husband says, "It can’t be seizures. She didn’t fall on the ground and bite her tongue." How will you explain seizure disorder to ER and her husband?
d. If ER is diagnosed with seizures, what will you teach ER and her husband about managing her seizure disorder?

Answers

Explanation:

1. what ER is experiencing can be regarded as simple partial seizure. This is why, in this type of seizure she still maintained awareness. This kind of seizure can cause someone to act the way she did by staring into space and continuously repeating the same thing.

2. The assessments and diagnostics are:

neurological assessmentEEG test to see if there are changes in her brain activity, this test helps to diagnose brain conditions especially in people that suffer from seizures.other assessments and diagnostics are CT scan and MRI scan.

3. Her husband clearly thinks that all kinds o seizures are the same. because she did not fall fall or bite her tongue he doesn't think she had a seizure. He has to be educated to know that seizures are of different types and each of these types have different symptoms. He should know that people can lose consciousness in one type and not lose consciousness in  the other, they may even be able to talk, and remember things during the attack.

4. If she is diagnosed to have seizures, I am going to teach her  and her husband to manage the condition by;

encouraging her on how necessary it is for her to always take her medications as the doctor prescribed.i would tell her to make sure that she avoids whatever can trigger stress, anxiety and emotional disorder.They should do away with sharp objects in  the house during such episodes.Whenever symptoms present themselves, they should report immediately.

It is true that Use of narcotic drugs over a long period time leads to the development of tolerance for the narcotic.

What is narcotic tolerance?Drug tolerance, also known as drug insensitivity, is a pharmacological term for a person's reduced response to a drug following repeated use. Increasing the dosage may re-amplify the drug's effects, but it also has the potential to accelerate tolerance, further reducing the drug's benefits.Heavy drinkers, for example, develop tolerance to alcohol (requiring them to consume larger amounts to achieve the same effect), yet excessive drinking can harm the liver, placing them at risk of intoxication even when only consuming small amounts.
