The answer to this statement is codein. Codein, or 3-Methylmorphine by its IUPAC name, is an opiate used as pain reliever and suppressor of coughs. Its structural formula is shown in the picture. The patient's dosage of these narcotics should be strictly prescribed by the doctor. When patients take this, they feel euphoria, hence, they tend to crave for that feeling once it's gone. Too much dosage of this drug would lead to addiction. Examples of drugs with this structural formula are Cotabflu, Nalex AC, T-Koff and Pediatuss.
562 grams because mass can not be created or destroyed
Answer:
if speed or direction changes then there is a change in velocity which is acceleration. Hope this helps!
Explanation:
Answer:
Improved water supply and sanitation and improved water resources management boost countries' economic growth and contributes greatly to poverty eradication. ... National economies are more resilient to rainfall variability, and economic growth is boosted when water storage capacity is improved
Explanation:
Solution: (a) The net force is zero because car is travelling with same speed that is 60 miles per hour or there is no acceleration.
(b) Mass of object is 10 kg
Acceleration is 2 m/s², thus force can be calculated as follows:
F=m×a
Here, m is mass of object and a is its acceleration thus,
F=10 kg×2 m/s²
=20 kg m/s²
Here, 1 N=1 kg m/s²
Thus, F=20 N
(c) Force on object is 17 N and its acceleration is 1.5 m/s².
Mass of the object can be calculated as follows:
m=\frac{F}{a}
thus,
m=\frac{17 N}{1.5 m/s^{2}}=11.33 (\frac{N}{m/s^{2}})
Here, 1 N=1 kg m/s²
Thus,
m=11.33 kg
