Acombination of 0.250 kg of water at 20.0°c, 0.400 kg of aluminum at 26.0°c, and 0.100 kg of copper at 100°c is mixed in an insulated container and allowed to come to thermal equilibrium. ignore any energy transfer to or from the container and determine the final temperature of the mixture.

23.63 °C

Explanation:

= mass of water = 0.250 kg

= initial temperature of water = 20.0 °C

= Specific heat of water = 4186 J/(kg °C)

= mass of aluminum = 0.400 kg

= initial temperature of aluminum = 26.0 °C

= Specific heat of aluminum = 900 J/(kg °C)

= mass of copper = 0.100 kg

= initial temperature of copper = 100 °C

= Specific heat of copper = 386 J/(kg °C)

= Final temperature of mixture

Using conservation of heat

( - ) + ( - ) + ( - ) = 0

(0.250) (4186) ( - 20) + (0.400) (900) ( - 26) + (0.100) (386) ( - 100) = 0

= 23.63 °C

i think it's 35 meters

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
