10 kg water falls through a distance of 854m and all the energy is effective in heating the water.To what temperature will the water be raised if it was initially at 20c?

Hello, I was wondering, when particles in the quantum foam appear do they bring energy with them? And if so would that mean that one would have to come in and one would have to go out at the same time to not add or remove energy from the universe?

Consider four uniformly charged plates oriented normal to the x-axis as shown. The drawing scale exaggerates the size of the

lengths along x compared to sizes along y

and z. Let L=1.0m, d=1.0mm, Q1=3.0C,

Q2=-3.0C, Q3=8.0C, and Q4=-6.0C. The positions of the plates are at x1, x2, x3 and x4.

1. a) Find the 2D charge density of each plate
2. b) Findthenetelectricfieldinregion
3. x2 <x<x3. 

35g of water at 0 degree Celsius is completely converted to ice at 0 degree Celsius by extracting 2 kilo joules of heat from it. If the specific heat capacity of water is 4200 joules per kilogram per Kelvin, calculate the specific latent heat of fusion of ice

The furnace is constructed with 20cm of brick where the k=1.36W/m°K, 10cm insulating brick with k=0.26W/m°K and 20cm of building brick with the k=0.69W/m°K. The inside surface temperature is 650°C. The heat losts from the furnace wall is 56W/m². Determine

a). The interface temperatures and the outside wall temperatures.

In the figure here, a block of ice slides down a frictionless ramp at angle θ=59.0 ˚ while an ice worker pulls on the block (via a rope) with a force that has a magnitude of 52.0 N and is directed up the ramp. As the block slides down through distance d = 0.500 m along the ramp, its kinetic energy increases by 84.0 J. How much greater would its kinetic energy have been if the rope had not been attached to the block?
