Complete Question:
In the same configuration of the previous problem 3, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a = 13.5 cm. Each wire carries 7.50 A, and the currents are out of the page in wires 1 and 4 and into the page in wires 2 and 3.
a) Draw a diagram in a (x,y) plane of the four wires with wire 4 perpendicular to the origin. Indicate the current's directions.
b) Draw a diagram of all magnetic fields produced at the position of wire 3 by the other three currents.
c) Draw a diagram of all magnetic forces produced at the position of wire 3 by the other three currents.
d) What are magnitude and direction of the net magnetic force per meter of wire length on wire 3?
Answer:
force, 1.318 ₓ 10⁻⁴
direction, 18.435°

Answer:
The final equilibrium temperature of the system is
For the ice it would melt completely the mass that would remain is Zero
Explanation:
In the following question we are provided with
Mass of the ice = 129 g = 0.129 kg
Mass of the steam = 19 g = 0.019 kg
Initial temperature is = 0°C
Temperature of steam = 100°C
Following the change of state of water in the question
The energy required by ice to change to water is mathematically given as
Where is a constant known as heat of fusion and the value is
The energy been released when the steam changes to water is mathematically given as
Where is a constant known as heat of vaporization and the value is
The energy released when the temperature of water decrease from 100°C to 0°C is
100°C)
Where is the specific heat of water which has a value
Looking at the values we obtained we noticed that ]
What this means is that the ice will melt
bearing in mind the conservation of energy
looking the way at which water at different temperature were mixed according to the question
Heat lossed by the vapor = heat gained by ice
