One of the most deadly features of an erupting volcano is an avalanche of hot ash and gas called a pyroclastic flow. A pyroclastic flow can move at a speed of over 160 km/h and can have a temperature of 1,088 K. What is this temperature in degrees Fahrenheit and degrees Celsius?

If an inclined plane is 5 m long and 2 m high, what is its mechanical advantage? a. 2.5 b. 3 c. 7 d. 10

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)

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