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?

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?

At time t=0, a particle is located at the point (3,6,9). it travels in a straight line to the point (5,2,7), has speed 8 at (3,6,9) and constant acceleration 2i−4j−2k. find an equation for the position vector of the particle.

Madison pushes with a 210-n horizontal force on a 24-kg crate of coffee resting on a warehouse floor. the force of friction on the crate is 74 n. what is the acceleration?
