An ice-cube tray contains 0.35 kg of water at 18°C. How much heat must be removed from the water to cool it to 0°C and freeze it? Let c = 4.19 × 103 J/(kg • K) and Lf = 3.34 × 103 J/kg.

Aparticle with mass 1.81×10−3 kg and a charge of 1.22×10−8 c has, at a given instant, a velocity v⃗ =(3.00×104m/s)j^. what are the magnitude and direction of the particle’s acceleration produced by a uniform magnetic field b⃗ =(1.63t)i^+(0.980t)j^?

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?
