Answer:

5.5552×10⁸ J

Explanation:

Given :

Volume of water = 82923 L

Since, 1 L = 0.001 m³

So,

Volume of water = 82.923 m³

Density=\frac{Mass}{Volume}

Density of water= 1000 kg/m³

So, mass of the water:

Mass\ of\ water=Density \times {Volume\ of\ water}

Mass\ of\ water=1000 kg/m^3 \times {82.923 m^3}

Mass of water  = 82923 kg

Net Heat transfer during heating:

Q=m_{water}\times C_{water}\times \Delta T

Given: ΔT = 1.6 °C

Specific heat of water = 4.187 kJ/kg°C

Q=82923\times 4.187\times 1.6\ kJ

<u>Q = 5.5552×10⁸ J</u>

What is the electric field strength inside the capacitor after insulating handles are used to pull the electrodes away from each
Bezzdna [24]
This question apparently comes after an EARLIER one,
where you were told either the voltage across the same
capacitor or the total charge stored in it.  You can't answer
THIS one without that information.

Gravitational energy can be negative?
AlladinOne [14]

answer:

yes

explanation:

At a separation of the surface of Earth (r=6400km) gravity wants pull the test mass closer and closer. ... So the work done by gravity is NEGATIVE. The gravitational potential energy is negative because us trying to do the opposite of what gravity wants needs positive energy.
