A parallel circuit contains four identical lamps. The current through the energy source is 4 A. The total resistance of the circ

TEA [102]

Answer:

b. 40V , 40V

Explanation:

Connections are as per the figure.

As total current through source is 4A , current through each lamp is 1A.

As total resistance of the circuit is 10Ω ,resistance of each bulb is 40Ω because in case of a parallel circuit in which identical objects are connected , $R_{eff} = \frac{R}{n}$ where R is the resistance of each bulb and n is the number of bulbs.

As per Ohm's law , voltage of the source =IR = 4×10 =40V.

We can see from the figure that if the voltage across the source is 40V , the voltage across each bulb is also 40V.

Ask Your Teacher A trough is 16 ft long and its ends have the shape of isosceles triangles that are 2 ft across at the top and h

zloy xaker [14]

Answer:0.210 ft/min

Explanation:

Given

Length of trough $L=16 ft$

width of base $b=2 ft$

height of triangle $h=1 ft$

From Similar triangles property

$\frac{4}{2x}=\frac{1}{y}$

$2y=x$

volume of water in time t

$V=\frac{1}{2}\times (2x\cdot y)\cdot$

$V=16xy$

$V=32y^2$

differentiating

$\frac{\mathrm{d} V}{\mathrm{d} t}=32\times 2\times y\times \frac{\mathrm{d} y}{\mathrm{d} t}$

at $y=8 in.\approx 0.667 ft$

$9=64\times 0.667\times \frac{\mathrm{d} y}{\mathrm{d} t}$

$\frac{\mathrm{d} y}{\mathrm{d} t}=\frac{9}{64\times 0.667}$

$\frac{\mathrm{d} y}{\mathrm{d} t}=0.210 ft/min$
