Carl adds a 6.70-gram cube of ice at 0.0°C to cool a glass of juice, As the ice melts, the temperature of
the newly melted water rises to 25.4°C. Water's heat of fusion is 334 joules/gram, and its specific heat
is 4.186 joules/gram degree Celsius. How many joules of energy did the ice cube gain?
Type the correct answer in the box. Express the answer to the correct number of significant figures

they are made of gases.

they have a spherical shape.

they make energy through fusion.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
