How high would you have to lift your 0.54kg textbook to give it 177 J of gravitational potential energy

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

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?

Specific heat refers to the amount of heat required to change 1 gram of a substance by degree(s) celsius
