Answer:

Energy consumed by the electric kettle in 9.5 min =Pt=(2.5×10

)×(9.5×60)=14.25×10

Energy usefully consumed =msΔT=3×(4.2×10

)×(100−15)=10.71×10

where s=4.2J/g

C= specific heat of water and boiling point temp=100

Heat lost =14.25×10

−10.71×10

=3.54×10

A proton is released in a uniform electric field, and it experiences an electric force of 2.04×10−14 N toward the south.

Lemur [1.5K]

Answer:

Part A:

$E=127500N/C\\E=1.275*10^{5} N/C$

Part B:

Option B (Towards the South)

Explanation:

Part A:

Magnitude if electric field E:

E=Force/charge

Force=2.04×10−14 N

Charge=1.6×10−19 C

$E=\frac{2.04*10^{-14}}{1.6*10^{-19}} \\E=127500N/C\\E=1.275*10^{5} N/C$

Part B:

Option B (Towards the South)

As electron is experiencing the force towards south,it means the direction of the electric field is towards the south because direction of field lines is from positive to negative, so proton is moving towards south it means negative charge is in south to which proton is attracted. So electric field is towards South.
