a = (dx / dt)²

Explanation: Unit of distance is m (metres) and unit of time is s (seconds) speed v is first derivative of distance x versus time:

v = dx / dt, unit is m/s. Acceleration is second derivative of

speed versus time a = (dx / dt)² = (dv/dt) , unit is m/s²

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.

a train engineer started the train from a standstill and sped up to 5 meters per second, she then rounded a corner at a constant

olasank [31]

for acceleration we can define that rate of change in velocity is know as acceleration

So whenever velocity of train is changing with time we can say train is accelerating

Now here if initially train is standstill then after some time its speed is 5 m/s

so here the train is accelerated first time

Then on straight path its speed changed from 5 m/s to 10 m/s so here train gets accelerated second time

After this train chugged around a curve with same speed 10 m/s

SO here since train is moving in curve so here its direction of velocity is continuously changing and this type of acceleration is known as centripetal acceleration

SO this is accelerated Third time

Then its speed decreases and it comes to speed of 5 m/s from 10 m/s

So here it is acceleration of train for Fourth time

Then finally train comes to stop so again its speed changed from 5 m/s to 0

so this is acceleration of train Fifth time

So total train will accelerate 5 times in whole path

Anyone know what solution this is?

Pavel [41]

Answer:a means of solving a problem or dealing with a difficult situation.

Explanation:Some examples of solutions are salt water, rubbing alcohol, and sugar dissolved in water. When you look closely, upon mixing salt with water, you can't see the salt particles anymore, making this a homogeneous mixture. Let's make use of our salt water example to talk about the two main parts of a solution.
