Answer:
There will be two forces acting on her: Gravitational force and Air resisitence
Answer:
The correct option is the third option
Explanation:
Firstly, it must be noted that chemicals/reagents that are sensitive to sunlight are stored in dark/amber container in the laboratory. Hence, the chloroform can only be found in an amber/dark bottle.
Also, reagents/chemicals that release poisonous/offensive gases are handled in the fume cupboard in the laboratory. Thus, If Malik is going to pour the chloroform, he should pour it in a fume cupboard to avoid inhaling it because of the toxicity of it's vapor.
From the above explanation, it can be deduced that <u>Malik should locate the chloroform stored in a dark container in chemical storage and should take it to the fume hood to pour</u>.
Explanation:
hello,
a = ( v - u ) / t
where u is the initial velocity.
and v is the final velocity.
t represents time,
and a represents acceleration.
in this case,
a = 1.4 m/s²
u = 6 m/s
v = 13 m/s
hence,
1.4 = (13 - 6)/t
1.4t = 7
t = 7/1.4
t = 5 s
thank you!
