Answer:
correct option is (A) 0.5
Explanation:
given data
axial column load = 250 kN per meter
footing placed = 0.5 m
cohesion = 25 kPa
internal friction angle = 5°
solution
we know angle of internal friction is 5° that is near to 0°
so it means the soil is almost cohesive soil.
and for a pure cohesive soil
= 0
and we know formula for
is
= (Nq - 1 ) × tan(Ф) ..................1
so here Ф is very less
should be nearest to zero
and its value can be 0.5
so correct option is (A) 0.5
Answer:
Temperature on the inside ofthe box
Explanation:
The power of the light bulb is the rate of heat conduction of the bulb, 
The thickness of the wall, L = 1.2 cm = 0.012m
Length of the cube's side, x = 20cm = 0.2 m
The area of the cubical box, A = 6x²
A = 6 * 0.2² = 6 * 0.04
A = 0.24 m²
Temperature of the surrounding, 
Temperature of the inside of the box, 
Coefficient of thermal conductivity, k = 0.8 W/m-K
The formula for the rate of heat conduction is given by:
Answer:
1. Parallel circuit
2. Parallel circuit
3. Series circuit
4. Series circuit
5. Parallel circuit
6. Parallel circuit
Explanation:
1. In a parallel circuit, there are multiple paths for current to flow. The path each current takes depends on the resistance of the resistors on that path.
2. In a parallel circuit, current splits up into various paths to get the total current through the circuit, the current flow through each resistor is added.
3. In a series circuit the voltage across each resistor is not the same. to get back the total voltage, the voltages across each resistor needs to be added.
4. Series circuits have voltage drops across each resistor. this makes the voltage across each resistor depend on the resistance of the resistor.
5. In parallel circuits voltage is the same across each resistor because they are all connected directly to the same source.
6. In parallel circuits, the power is the same in each resistor of equal resistance since the voltage across each resistor is the same
