Answer:
Based on color theory it would come out as brown
Explination:
Basic color theory states the primary colors are red yellow and blue. Expanding that to the rainbow you know. Red plus yellow equals orange. Yellow plus blue equals green. And blue plus red equals purple. Red and Green are opposite colors and when you combine opposite colors you get brown
Answer:
a) E = 4.5*10⁴ V/m
b) C= 17.7 nF
c) Q = 159. 3 nC
Explanation:
a)
- By definition, the electric field is the electrostatic force per unit charge, and since the potential difference between plates is just the work done by the field, divided by the charge, assuming a uniform electric field, if V is the potential difference between plates, and d is the separation between plates, the electric field can be expressed as follows:
b)
- For a parallel-plate capacitor, applying the definition of capacitance as the quotient between the charge on one of the plates and the potential difference between them, and assuming a uniform surface charge density σ, we get:
From (1), we know that V = E*d, but at the same time, applying Gauss'
Law at a closed surface half within the plate, half outside it , it can be
showed than E= σ/ε₀, so finally we get:
c)
- From (3) we can solve for Q as follows:
When the concrete structure avails it maximum strength, it is safer to place construction load on it. Usually, the concrete gain it maximum strength after 28 days. Concrete when cast take initial settlement on 7 days. Curing is done continuously through the period so that there is no crack occur due to heat transfer. There are various method of concrete curing. On a horizontal surface/ roof/ floor, curing is done through ponding or spreading wet sheets. Testiment/ sample of the concrete are cured by immersion in water tank. After 28 days of curing, concrete gains it maximum strength and can be used for test or usage. Construction load limit is considered in designing/ proportioning the specimen. So the applied load is equal or less than the limit for which it is actually designed.
