C2H5OH (l) + 3 O2 (g) = 2 CO2 (g)+ 3 H2O (l/g)
Answer:
the bending moment will be W from either sides
Explanation:
bending moment= force (load) * perpendicular distance, if I understand the question the distance will be 1/2 of the length
=> f x 1/2(l) =W*1/2(2) =W
Answer:
Explanation:
a ) 12.0 lbs - mass
b ) .34 g - mass
c ) 120 kg - mass
As lbs , g and kg are units of mass , these things represent mass . lbs is FPS unit of mass and kg is SI unit . g is CGS unit of force .
d ) 1600 kN It represents force because kN or kilonewton is unit of force .
e ) it represents , length or distance because m or metre is unit of length .
f ) 411 cm It represents length or distance because cm is smaller unit of length
g ) 899 MN or million newton . Like d ) It also represents force . Million newton is higher unit of force .
Answer:
(L: Length, T: Time)
p: Dimension: L; unit: m
q: Dimension: L/T or (L)*(T)^-1; unit: m/s
r: Dimension: L/T^2 or (L)*(T)^-2; unit: m/s^2
Explanation:
since y is distance (Length), make all terms L distance.
p is same as y dimension ==> dimension: L; unit: m (meter)
qt dimension is L ==> q dimension :L/T; unit: m/s
rt^2 dimension is L ==> r dimension : L/T^2; unit: m/s^2
1.06 is the <u>maximum</u> refractive index that the liquid may have for the light to be totally reflected.
Only when a light source passes from a denser to a rarer medium can it completely reflect.
When the angle of incidence surpasses a specific critical value, specular reflection occurs in the more highly refractive of the two mediums at their interface, and this reflection is known as total reflection.
sin 
= μ
/ μ
From the diagram
Angle of incidence = 60°
sin60° ≥ sin = μ/μ
μ ≤ μ sin60°
μ ≤ √1.5 × √3/2
= 1.06
Hence, the maximum index that the liquid may have for the light to be totally reflected is 1.06
