The value is
Explanation:
From the question we are told that
The mass of the ice cube is
The temperature of the ice cube is
The mass of the copper cube is
The final temperature of both substance is
Generally form the law of thermal energy conservation,
The heat lost by the copper cube = heat gained by the ice cube
Generally the heat lost by the copper cube is mathematically represented as
The specific heat of copper is
Generally the heat gained by the ice cube is mathematically represented as
Here L is the latent heat of fusion of the ice with value
So
=>
So
=>
Answer:
The curl is
Explanation:
Given the vector function
We can calculate the curl using the definition
Thus for the exercise we will have
So we will get
Working with the partial derivatives we get the curl
