Answer:

<u><em>A glass rod becomes positively charged when it is rubbed by a silk because the glass rod is negetively charged and when it is rubbed by the conductors like silk it gets positive charged.</em></u>

Answer:

Hope this helps ya out

Explanation:

The core has positive charge, the electrons have negative charge. When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth. This leaves the glass rod with more positive than negative charge, so you get a net positive charge.

zepelin [54]

Answer:

a)5mm

b)3.3%

Explanation:

first note down the what's given

Y_{tendon} = 0.15x10^{10} N/m^{2}

Area=A= 1.1x10^{-4} m^{2}

Mass of the runner=m_{r}=70kg

Fmax= 8 F (since tendon can stretch 8 times of runner's weight)

= 8 m_{r}g=8 x 70 x 9.8=> 5488N

L=15cm=> 0.15m

a)We know that, Y={Fmax.L}/AΔL

YAΔL=Fmax. L

ΔL=\frac{Fmax L}{YA} =\frac{5488*0.15}{0.15x10^{10}x1.1x10^{-4}  }

ΔL=4.99x10^{-3} m => 5mm

b) L=15cm= 150mm

Fractional change can be determined by,

(ΔL/L) *100

=\frac{4.99}{150} *100

=3.33%

An overhead electric power line carries a maximum current of 125 A. What is the magnitude of the maximum magnetic field at a poi
BARSIC [14]

Answer:

B= 55.6×10^(-7) Tesla

Explanation:

B= μoI/(2πr)

B:  magnetic field strength

μo: permeability of free space and is equal to  4π×10^(-7) T.m/A

r: distance from the wire

I : current in the wire

B= (4π×10^(-7)×125)/(2π×4.5)

B= 55.6×10^(-7) Tesla
