The diagram shows a heating curve for a substance. A graph titled heating curve of Substance It shows heat added in joules on the x-axis, and temperature in degrees celsius on the y-axis on a scale of 0 to 100. The graph has a diagonal line from negative 5 degrees up to zero degrees labeled U. A horizontal line segment at zero degrees labeled V. A diagonal line segment from zero degrees up to 120 degrees labeled W. A horizontal line segment at 120 degrees labeled X and then another diagonal segment labeled Y.

Which segment shows the substance changing from a gas to a liquid?

Aferris wheel is a vertical, circular amusement ride with radius 9 m. riders sit on seats that swivel to remain horizontal. the ferris wheel rotates at a constant rate, going around once in 9 s. consider a rider whose mass is 56 kg. at the bottom of the ride, what is the perpendicular component of the rate of change of the rider's momentum? at the bottom of the ride, what is the vector force exerted by the seat on the rider?

There are weak or strong attractive forces between atoms of liquids with a high viscosity

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to. in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
