Answer:
a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions.
Explanation:
. Materials made of metal are common electrical conductors.
Answer:
Explanation:
Volume of cube=side³
=2*2*2
=8 cm³
Mass of cube=40g
Its density=mass/volume
=5g/cm³
which differs the value given in the text hence it is not gold and u should not bye it...
Instead u should call the police for arresting the person lol...
Answer:
exit velocity = 62 m/s
exit pressure is 98.52332 kPa
Explanation:
given data
pressure p1 = 80 kPa
temperature t1 = 27°C = 300 K
velocity v1 = 220 m/s
temperature t2 = 42°C = 315K
area exit = 370 cm²
lose heat at a rate = 18 kJ/s
gas constant of air = 0.287 kPa·m^3/kg·K.
h1 = 300.19 kJ/kg
h2 = 315.27 kJ/kg
to find out
exit velocity and exit pressure
solution
first we apply here energy balance equation to find out outlet velocity
Einlet = Eoutlet
m(h1 + v1²/2) = m (h2+v2²/2) +Q
m(v1²-v2²) /2 = m (h2 -h1) +Q
v2² = v1² - 2Cp Δt - 2Q/m
here Δt = h2 - h1 and put all value
v2² = 220² - 2(1.005)10³ (15) - 2(18)10³ /2.5
exit velocity = 62 m/s
so
now find outlet pressure that is
p2 = mRT / A2 v2
put value
p2 = 2.5 (287) 315 / (370
62)
p2 = 98.52332 kPa
exit pressure is 98.52332 kPa
S=(0x4)+(0.5x4.81x4x4)
S=0.78.48
The depth is approximately 78 meters.
(My brain hurts now) :P Good Luck!
Answer:

Explanation:
Given that
Diameter of small loop d= 2 mm or r=1 mm
Diameter of large loop D= 100 mm or R=50 mm
We know that induce emf given as






So induce current
i=emf/R
