The complete question is :
Charlie is investigating friction. She will use the same amount of force to push two wooden balls across two level surfaces. Then she will record her results in the table below.
Which prediction will most likely describe how friction will affect her findings?
Answer:
The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.
Explanation:
The frictional force depends greatly on the roughness of the body surfaces. It acts opposite to the direction of motion when two body surfaces have a relative motion between them.
In the context, equal mount of force is applied to push the wooden balls. So the net force which acts on the balls are :
F' = F - f
Here, F = the force applied
f = force of friction
And f = μ.N (N = reaction force)
Here μ is the coefficient of friction that depends on the surface roughness. The frictional force will be less when the surfaces are smooth. Thus for the trails 3 and trial 4, the distance for trail 3 would be greater than trail 4 as the surface is polished and would offer less friction.
Answer:
This tool is divided into three sections representing the principles in the Medication practice standard: authority, competence, and safety.
Explanation:
Rights of Medication Administration
1. Right patient
- Check the name of the order and the patient.
- Use 2 identifiers.
- Ask patient to identify himself/herself.
2. Right medication
- Check the medication label.
- Check the order.
3. Right dose
- Check the order.
- Confirm the appropriateness of the dose using a current drug reference.
4. Right route
- Again, check the order and appropriateness of the route ordered.
- Confirm that the patient can take or receive the medication by the ordered route.
5. Right time
- Check the frequency of the ordered medication.
- Double-check that you are giving the ordered dose at the correct time.
- Confirm when the last dose was given.
6. Right documentation
- Document administration AFTER giving the ordered medication.
- Chart the time, route, and any other specific information as necessary.
7. Right reason
- Confirm the rationale for the ordered medication. What is the patient’s history? Why is he/she taking this medication?
8. Right response
- Make sure that the drug led to the desired effect. If an antihypertensive was given, has his/her blood pressure improved?
- Does the patient verbalize improvement in depression while on an antidepressant?
Answer: Atmosphere
Explanation:
Atmosphere is the part of the earth, known as the gaseous part, since it contains gases such as nitrogen (about 78%), oxygen (about 21%), Carbondioxide (about 0.03%), and rare gases to make the rest.
Thus, atmosphere contains the most whole of oxygen and carbon dioxide
Answer: crossing over happens in prophase 1.
Explanation: ( in Portuguese ) os cromossomas homólogos, na profase 1 da meiose, tocam-se, trocando informações sobre o ADN. A esse processo chama se crossing over.
The correct answer should be Carrying capacity
Carrying capacity is the the number of people, animals, and other life forms, that an ecosystem can sustain without starting to degrade, and all these upsets can destroy it because it can cause people and animals to migrate somewhere or they can destroy the carrying capacity of the already existing one.
