Answer:
a) a = 4.9 m/s²
b) a = 1.5 m/s²
Explanation:
no friction
F = ma
gsinθ = ma
a = gsinθ
a = 9.8sin30
a = 4.9 m/s²
friction
gsinθ - μmgcosθ = ma
a = g(sinθ - μcosθ)
a = 9.8(sin30 - 0.4cos30)
a = 1.5051...
Answer:
Iris
Explanation:
The iris seems to be the illuminated portion of the eyes which really covers the pupil. It controls the amount of light reaching the eye. The lens is indeed a translucent layer of the retina that serves to concentrate light and objects on the lens.
Answer:
342 m/s
Explanation:
The velocity of sound in air is approximated as:
v ≈ 331.4 + 0.6 T
where v is the velocity in m/s and T is the temperature in Celsius.
At T = 18:
v ≈ 331.4 + 0.6 (18)
v ≈ 342.2
The velocity is approximately 342 m/s.
Answer:
subs
Explanation:
I've seen subliminals online that are supposed to help shifting. You could see for yourself if they work for you. You could probably also use the method where you act like you already have your desires and results. I have seen a lot of people act as if they have their desires and affirm it constantly. Ex: you want to lose weight, so you act as if you already are your desired weight and tell yourself that you are such and such weight, and don't contradict it by saying that you aren't. I hope that this helps.
