Physics

The power of a force acting on a particle can be written as p = F v, and the standard SI unit of power is the watt, W. Which of the following is not an SI unit of power. s^3 / (kg m^2) W kg m^2 / s^3 N m/s The energy transferred to a particle can be written E = P Delta t and has standard SI units of joules (J), where p is the power, and Delta t is the temporal (time) duration the power is applied. Which of the following is an incorrect equivalent to the joule? W/s N m Ws kg (m/s)^2 Newton's Second Law is F = ma where: F is the net force with standard SI units of newtons (N), m is the mass with standard SI units of kilograms (kg), and a is the acceleration with standard SI units of meters per second per second (m/sA2). An experiment is performed where a is measured in m/sA2, but m is measured in grams (g) instead of kg. What are the natural derived units of force when m and alpha are multiplied? In other words, what is a gram meter per second squared? tonne mN nN uN MN kN cN Ibf
