What is the current in milliamperes produced by the solar cells of a pocket calculator through which 3.70 C of charge passes in
Kaylis [27]

Answer:

Current flowing in the cell will be equal to 0.1284 mA

Explanation:

We have given charge q = 3.70 C

And time through which charge is flowing = 8 hour

We know that 1 hour = 60 minutes, and 1 minute = 60 sec

So 1 hour = 60×60 = 3600 sec

So 8 hour = 8×3600 = 28800 sec

We know that current is rate time rate of flow of charge

So current i=\frac{q}{t}=\frac{3.70}{28800}=1.284\times 10^{-4}A=0.1284mA

So current flowing in the cell will be equal to 0.1284 mA

A very long thin wire carries a uniformly distributed charge, which creates an electric field. The electric field is (2300 N/C ,
Leto [7]

Answer:

λ= 5.24 × 10 ⁻² nC/cm

Explanation:

Given:

distance r = 4.10 cm = 0.041 m

Electric field intensity E = 2300 N/C

K = 9 x 10 ⁹ Nm²/C

To find λ = linear charge density = ?

Sol:

we know that E= 2Kλ / r

⇒ λ = -E r/2K         (-ve sign show the direction toward the wire)

λ = (- 2300 N/C × 0.041 m) / 2 ×  9 x 10 ⁹ Nm²/C

λ = 5.24 × 10 ⁻⁹ C/m

λ = 5.24 nC/m = 5.24 nC/100 cm

λ= 5.24 × 10 ⁻² nC/cm

A bicycle has a momentum of 36 kg* m/s and a very!I city of 4 m/s.What is the mass of the bicycle?
Strike441 [17]

p = 36 kgm/s

v = 4m/s

we know that,

p = mv

so,

m =  \frac{p}{v}

m  =  \frac{36}{4}

m = 9kg
