Explanation:

2). Newton's second law of motion F= ma or force is equal to mass times of acceleration. ACCORDING TO NEWTON'S 2ND LAW OF MOTION ALSO KNOWN AS LAW PF FORCE AND ACCELERATION.

3). the formula for density is the mass of an object divided by its volum. d= m/ v To work out density p= m/v, To work out mass = m= p× v ,To work out volume = m/p I hope it helps you g
