Answer:

1.50\ *10^{-6} }

Explanation:

Given

e=100 N/C

M=0.15 g

q=\ 22\  pC\\=\ 22\ *10^{-2}

The  ratio of the electric force on the bee to the bee's weight can be determined by the following formula

\frac{fe}{M*9.81}

\frac{22*10^{-12\ *\ 100} }{0.15*\ 10^{-3} *\ 9.81}

=\ 1.50\ *10^{-6}

A diverging lens (f1 = -12.0cm) is located 50.0 cm to the left of a converging lens (f2 = 34.0 cm). A 2.0 cm-tall object stands
pishuonlain [190]

Answer:

The final image relative to the converging lens is 34 cm.

Explanation:

Given that,

Focal length of diverging lens = -12.0 cm

Focal length of converging lens = 34.0 cm

Height of object = 2.0 cm

Distance of object = 12 cm

Because object at focal point

We need to calculate the image distance of diverging lens

Using formula of lens

\dfrac{1}{v}=\dfrac{1}{f}-\dfrac{1}{u}

\dfrac{1}{v}=\dfrac{1}{-12}-\dfrac{1}{-12}

v=\infty

The rays are parallel to the principle axis after passing from the diverging lens.

We need to calculate the image distance of converging lens

Now, object distance is ∞

Using formula of lens

\dfrac{1}{v}=\dfrac{1}{34}-\dfrac{1}{\infty}

v=34

The image distance is 34 cm right to the converging lens.

Hence, The final image relative to the converging lens is 34 cm.

The resistivity of a given wire of cross sectional area 0.7mm is 4.9*10-4mm.Calculate the resistance of 2m length of the wire
Masja [62]

Answer: 1.4\ \Omega

Explanation:

Given

Cross-sectional area A=0.7\ mm^2

Resistivity \rho =4.94\times 10^{-4}\ \Omega-mm

Length of wire l=2\ m\ or\ 2000\ mm

Resistance is given by

\Rightarrow R=\dfrac{\rho l}{A}\\\\\text{Insert values}\\\\\Rightarrow R=4.9\times 10^{-4}\times \dfrac{2000}{0.7}\\\\\Rightarrow R=1.4\ \Omega
