Answer:
Time taken for the capacitor to charge to 0.75 of its maximum capacity = 2 × (Time take for the capacitor to charge to half of its capacity)
Explanation:
The charging of a capacitor/the build up of its voltage follows an exponential progression and is given by
V(t) = V₀ [1 - e⁻ᵏᵗ]
where k = (1/time constant)
when V(t) = V₀/2
(1/2) = 1 - e⁻ᵏᵗ
e⁻ᵏᵗ = 0.5
In e⁻ᵏᵗ = In 0.5 = - 0.693
-kt = - 0.693
kt = 0.693
t = (0.693/k)
Recall that k = (1/time constant)
Time to charge to half of max voltage = T(1/2)
T(1/2) = 0.693 (Time constant)
when V(t) = 0.75
0.75 = 1 - e⁻ᵏᵗ
e⁻ᵏᵗ = 0.25
In e⁻ᵏᵗ = In 0.25 = -1.386
-kt = - 1.386
kt = 1.386
t = 1.386(time constant) = 2 × 0.693(time constant)
Recall, T(1/2) = 0.693 (Time constant)
t = 2 × T(1/2)

Answer:
5320.6 Pascal
Explanation:
Manometer is a pressure measuring device use to measure gas pressure .
Pressure difference in Manometer is a function of density,gravity and the height difference of the liquid.
Pressure difference = density x acceleration due to gravity x difference in height of liquid
Density of liquid = specific gravity of object x density of water.
Density of water = 997 kg/m^3
Specific gravity of liquid = 1.7
Density of liquid = 997 x 1.7 =1694.9kg/m^3
g= 9.81 m/s^2
h =320mm = 0.320m
Pressure difference = 1694.9 x 9.81 x 0.320 = 5320.6 Pascal
Hacking is correcttttttttt
Answer:
A complex system is a system composed of many components which may interact with each other.
ADVANTAGES
Structs are marginally faster at runtime than classes, due to optimisations done by the compiler. You can enforce full immutability. If you declare a struct instance as let, you will not be able to change its properties.
DISADVANTAGES
A complex corporate structure makes communication more difficult. For instance, when workers must interact with several supervisors, the various directives might work at cross purposes. Also, messages might get lost in the shuffle if there is no simple way to communicate within the organization.
