An electron has a speed of 0.75c. Find the speed of a proton that has (a) the same kinetic energy as the electron and (b) the same momentum as the electron. What are the units of impulse? What is the delta kinetic energy for a vehicle that goes from +10 mph to -10 mph?
The base unit for measuring mass in the metric system is the gram. All other units of measuring mass just have prefixes added to them to denote how... See full answer below. much of a gram, or how many grams, they represent. The most commonly used units of measur...
Speed is measured as the ratio between the distance and time and the SI unit of speed is m/s. It is the change in the position of an object with respect to time. There are four types of speed: uniform speed, variable speed, average speed, and instantaneo

How to Find Mass What Units are Used to Measure Mass? How is Mass Different From Weight? How is Mass Applied in Real Life? Lesson Summary FAQs Activities What is mass equal to? Mass is equal to the following: Mass is equal to the density multiplied by volume. Mass is equal to en...
One of the earliest device to measure time was the sundial; which used the movement of the shadows caused by the sun's motion across the sky as a way to measure time. The use of units like seconds and minutes which are radial angle measurements in geometry may be pointing toward the ori...
The sugar industry was built not only at the expense of human rights, but also that of ecosystem health. Coastal cane fields are major contributors to ocean pollution, which is causing mass coral bleaching, storm damage and soil erosion from deforestation and pesticide and fertiliser runoff. More...
In everyday use and in kinematics, the speed (commonly referred to as v) of an object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity. The average speed of an object in...
