A jet of steam at 100degrees Celsius is directed on a large block of ice at 100 degrees Celsius for a short time. o.4 kg of steam condenses to form water and some ice is melted at 8 degrees Celsius. Calculate the heat given out by this mass of steam in converting to water without a change in temperature. calculate the heat given out by this steam in changing to water without change in temperature specific latent heat of vaporisation of water as 2200kj/kg ii calculate the heat given out by this water as it cools to the temperature of the ice heat capacity to be 4.2kj/kg​

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

You throw a baseball directly upward at time =0 at an initial speed of 14.9 m/s. what is the maximum height the ball reaches above where it leaves your hand? ignore air resistance and take =9.80 m/s2.

In the middle of the night you are standing a horizontal distance of 14.0 m from the high fence that surrounds the estate of your rich uncle. the top of the fence is 5.00 m above the ground. you have taped an important message to a rock that you want to throw over the fence. the ground is level, and the width of the fence is small enough to be ignored. you throw the rock from a height of 1.60 m above the ground and at an angle of 54.0 degrees above the horizontal. part a part complete what minimum initial speed must the rock have as it leaves your hand to clear the top of the fence? express your answer with the appropriate units. part b for the initial velocity calculated in the previous part, what horizontal distance beyond the fence will the rock land on the ground?
