Answer:
778.4°C
Explanation:
I = 700
R = 6x10⁻⁴
we first calculate the rate of heat that is being transferred by the current
q = I²R
q = 700²(6x10⁻⁴)
= 490000x0.0006
= 294 W/M
we calculate the surface temperature
Ts = T∞ + 
Ts = 
The surface temperature is therefore 778.4°C if the cable is bare
Answer:
hello your question is incomplete below is the missing part of the question and attached is the missing diagram
In the simply-supported beam shown in the figure below, d1=14 ft, d2=7 ft, and F=15 kips. so find Az, Ay, By.(in kips)
answer :
Reaction force at B = 10 kips
Reaction force in the y axis = 5 kips
Reaction force in the Z direction = 0 kips
Explanation:
Taking moment about point A
∑ Ma = 0
By + ( d1 + d2 ) - F*d1 = 0
By ( reaction force at B ) = ( 15 * 14 ) / ( 21 ) = 10 kips
Applying equilibrium forces in the Y-axis
∑ Fy = 0
Ay - F + By = 0
where : F = 15, By = 10
hence ; Ay = 5 kips
applying equilibrium forces in the Z-direction
∑ Fz = 0
Az = 0 kips
Answer:
An electric current in a circuit transfers energy from the battery to the circuit components. No current is 'used up' in this process. In most circuits, the moving charged particles are negatively charged electrons that are always present in the wires and other components of the circuit.
The answer to your question should be 630, if you have a roof the size of 40 feet, by 35 feet.
If the roof is 40 inches, by 35 inches, you would have collected 4.36 inches of rain.
Explanation: To calculate this you are going to do this:
Length of the roof ______ feet * width of roof _______ feet * .6 gallons per square feet *.75 * ________ however many inches of rain
* means multiply
There should be a 6" free conductor left for splicing
Why there should be 6" splicing?
You must leave the junction box with at least six inches of free conductor wiring when running electrical cables from the box to the box for connecting needs.
Actually, 6-8 inches can be left when running the electric cables, additionally even if the grounded conductor is to be spliced in a 12-inch by 12-inch.
Conductor splicing: A splice, which can be finished using either the crimping or soldering method, is the joining of two or more conductors in a way that produces a permanent electrical termination and mechanical link.
Hence we can conclude that 6 inches is fine for the conductor splicing
