A400 gram sample of alcohol at 10o c [ca=2.64 j/g*oc] is mixed with 400 grams of warm water [cw=4.186 j/g*co] at 88o c. assume no heat is lost to the surroundings, what is the final temperature of the mixture when thermal equilibrium is reached?

alcohol = -[warm water]
mcaδt = -[mcwδt]
can u pls?

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?

What is the magnitude of the gravitational force acting on the earth due to the sun?
