We know that when you heat up calcium sulfate all the water has evaporated from it. That means that the mass of water that was initially in the sulfate is the difference in mass of the sulfate before and after the heating.
In order to <span>get a percentage by mass we simply divide this number by the initial amount of sulfate:

Answer:
b. 9.5°C
Explanation:
= Mass of ice = 50 g
= Initial temperature of water and Aluminum = 30°C
= Latent heat of fusion = 
= Mass of water = 200 g
= Specific heat of water = 4186 J/kg⋅°C
= Mass of Aluminum = 80 g
= Specific heat of Aluminum = 900 J/kg⋅°C
The equation of the system's heat exchange is given by
The final equilibrium temperature is 9.50022°C
Given :
Potential difference, V = 300 V.
Magnetic Field, B = 0.001 T.
To Find :
The magnitude of the magnetic force on the electron.
Solution :
We know, for perpendicular orientation, force is given by :
Hence, this is the required solution.
<span>Joule was educated at home with private tutors. He had to take over the brewery at a young age and missed out on attending university. Despite this, his home schooling was exceptional and led to him continuing to study science in a home based laboratory where he experimented before and after work. Joule submitted his work on the relationship of heat, electricity and mechanical work to numerous publications but it was widely ignored until William Thomson found it in 1847. He recognized Joule's work worked with an unifying pattern that was newly emerging in physics and excitedly endorsed it. Soon many other big names in the science field began rallying behind Joule's work.</span>
