Which statement shows the difference between drug misuse and drug abuse?
saul85 [17]

Drug misuse is when someone takes medicine in an unintended way, while drug abuse is when a person uses drugs in an illegal way.

Explanation:

Drug misuse simply refers to the inappropriate use of drug for the wrong purpose. The use of drug meant for someone else is a misuse of drug. Drug misuse have serious consequences on the body system. It works like a wrong prescription by a pharmacist.

Drug abuse is the simply the act of not following the instruction guiding the use of the drug on the label. This can lead to overdose of the drug whereby too much quantity of the drug is consumed. Under-dose of the drug also implies that less amount of the drug is used as stated. Drug abuse is very dangerous act and it can lead to serious health defect and addiction problems.

It is simply an illegal way of using drugs.

Both drug misuse and abuse implies that drug use does not follow due medical instructions and consultation.

An object of mass 20g taken at a height of 2m above the ground. Which type of energy is possessed by the object at this height ?
In-s [12.5K]
<h3><u>Given</u> </h3>
  • Mass of an object is \bf\red{20 g}
  • Height of the body is \bf\green{2 m}
<h3><u>To Find</u></h3>
  • Value of the energy

<h3><u>Solution</u></h3>

{\purple {\underline{\boxed{\sf{ Potential\: Energy \:=\: mgh}}}}}

Where,

  • \sf\red{m} = Mass
  • \sf\green{g} = Gravity
  • \sf\blue{h} = Height

Now, Converting gram to kg

\longrightarrow\: 1000g = 1kg

\longrightarrow\: 20g = \sf\dfrac{20}{1000}

\longrightarrow\: = 0.02 kg

According to the question

\sf\red{Mass \:= \:0.02 kg}

\sf\green{Gravitational \;force \:= \;10 m/s^{2}}

\sf\purple{Height\: =\: 2 m}

Putting these values

\to\: Potential Energy = mgh

\to\: Potential Energy = 0.02 × 10 × 2

\to\: Potential Energy = 0.2 × 2

\to\: Potential Energy = \bf\pink{0.4\:joules}

For a science, you must build a model of an aquiefier. What material would be best to use for where the water will accumulate?
aleksklad [387]
Answer is C.

Water-holding capacity is controlled primarily by soil texture, and amount of organic matter. Soils with small particles containing clay have a larger surface are than those larger sand particles, and a large surface area that allows to hold more water.

Based on what you have learned in previous chapters, which of the following measurements would we use to determine which galaxie
andriy [413]

Answer:

the answer es c, the doppler Shift of spectral lines within the galaxy's spectrum

Explanation:

This is due to redshift, red approach or redshift, occurs when electromagnetic radiation, usually visible light, which is emitted or reflected from an object, is shifted to red at the end of the electromagnetic spectrum. More generally, redshift is defined as an increase in the wavelength of electromagnetic radiation received by a detector compared to the wavelength emitted by the source. This increase in wavelength corresponds to a decrease in the frequency of electromagnetic radiation. Instead, the decrease in wavelength is called blue shift. Any increase in wavelength is called "redshift", even if it occurs in electromagnetic radiation of non-visible wavelengths, such as gamma rays, X-rays and ultraviolet radiation. This designation can be confusing since at longer wavelengths than red (eg infrared, microwave and radio waves), "redshifts" move away from the red wavelength. So when talking about frequencies of waves smaller than red continues to mean that the wavelength tends to lengthen and not resemble red.

A redshift can occur when a light source moves away from an observer, corresponding to a Doppler shift that changes the perceived frequency of the sound waves. Although the observation of such redshifts, or their counterpart, towards blue, has numerous terrestrial applications (eg Doppler radar and radar gun),  astronomical spectroscopy uses Doppler redshifts to determine the movement of distant astronomical objects. This phenomenon was first predicted and observed in the 19th century when scientists began to consider the dynamic implications of the wave nature of light.

michael boarded a plane and flew for 2 hours over a distance of 900 miles he then returned home on another 2 hour plane ride tra
Readme [11.4K]
Adding both distances together, you get a total of 1800 miles. With the total travel time of 4 hours, you divide the distance traveled by the time it took. so 1800/4=450 mph
