Steam burns are pretty dangerous because there's often a lot of thermal energy in the steam. When the steam hits you, it is going to

transfer some of that energy to you, cooling the steam. If a 6.4 kg cloud of

steam at 150 degrees, hits you and cools to 100 degrees, What is the loss

of heat energy? (no scientific notation)

In the image, the arrow is pointing to a celestial object. which attribute disqualifies the object from being a planet?

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

What do elements in a family tend to share. a.) similar periods b.) similar groups c.) similar atomic symbols d.) similar chemical properties and characteristics
