On a hot summer day, you decide to make some iced tea. first, you brew 1.50 l of hot tea and leave it to steep until it has reached a temperature of ttea = 75.0 ∘c. you then add 0.975 kg of ice taken from the freezer at a temperature of tice = 0 ∘c. by the time the mix reaches equilibrium, all of the ice has melted. what are the interacting systems in this problem?

260 miles per hour

explanation:

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

probably not if net force is zero
