Is there a relationship between mass and speed and computing kinetic energy Why?
Is there a relationship between mass and speed and computing kinetic energy Why? An object with less speed and more mass could potentially have the same Kinetic energy. The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic […]
What is the next step after radiation for prostate cancer?
What is the next step after radiation for prostate cancer? After radiotherapy or brachytherapy, your PSA should drop to its lowest level (nadir) after 18 months to two years. Your PSA level won’t fall to zero as your healthy prostate cells will continue to produce some PSA. Your PSA level may actually rise after radiotherapy […]

What liquid is less dense than water?
What liquid is less dense than water? vegetable oil Does density make something heavier? Less Dense, More Dense If something is heavy for its size, it has a high density. Why do dense things feel heavier? The expectation that a larger object will feel heavy is presumably caused by the fact that larger objects generally […]
