Answer:
The element that is oxidized is carbon.
Its oxidation state increased. It increased from -4 to +4
Explanation:
Oxidation is a process that involves increase in oxidation number.
The oxidation number of carbon in CH4 is -4
C + (1×4) = 0
C + 4 = 0
C = 0 - 4 = -4
The oxidation number of carbon in CO2 is +4
C + (2×-2) = 0
C - 4 = 0
C = 0+4 = 4
Increase in the oxidation number of carbon from -4 to +4 means carbon is oxidized
Answer:
axial stress in bar B = 25Mpa.
Deformation of bar A = 0.4mm.
Explanation:
PS: Kindly check the attached picture for the diagram showing the two bars that is to say the bar A and the bar B.
So, we are given the following data or information or parameters which we are going to use in solving this particular question or problem. Here they are;
The cross-sectional areas of Bars A and B = 400 mm2, the modulus of elasticity of bar A and bar B = 200 GPa, applied force = 10kN.
STEP ONE: The first step is to determine or calculate the axial stress in bar B. Therefore,
Axial stress in bar B = 10 × 10³ ÷ 400 × 10⁻⁶ = 25 Mpa.
STEP TWO: The second step here is to determine or calculate the deformation of bar A. Therefore,
The deformation of bar A = 20 × 10³ ×1.5 ÷ 400 × 10⁻⁶ × 200 × 10³ = 0.375 mm.
Answer:
a regular sized microwave will use 850 to 1800 watts depending on the model. An average modern microwave will use around 1200 watts.

Explanation:
Answer:
21.6 kw
Explanation:
Given data:
m = 50 kg/s
Inlet pressure (p1) = 2 bar
outlet pressure(p2) = 6.2 bar
suction ( h1 ) = -2.2 m
delivery ( h2 ) = 8.5 m
d1 = 200 mm = 0.2 m
d2 = 100 mm = 0.1 m
Vs of water = 0.001 m^3/kg
next we have to determine the Q value
Q = V*A
Q = 0.001 * 50 = 0.05 m^3/s
next we have to calculate the various V's
V1 = Q/A1 =
= 1.59 m/s
V2 = Q/A2 =
= 6.37 m/s
Determine the capacity of the electric motor
