Question

if the units of mass, time ,and length are quadrupled each, then magnitude of impulse becomes how many times ,the previous value?

Answer 1

if the units of mass, time ,and length are quadrupled each, then magnitude of impulse becomes how many times ,the previous value?

solution :
             we know that
               impulse = force *time
                           = mass * acceleration *time
                           = mass * velocity / time *time
                           =mass*velocity
                           =mass*displacement /time
                           = MLT⁻¹

      Let mass = M  , Length = L and time = T
             therefore ,
                           Magnitude of Impulse = MLT⁻¹
             according to question ,
                         mass = 4M
                       Length = 4L
                       time = 4T
     therefore ,
             Magnitude Of Impulse (when M,L and T are Quadrupled)  = 4M *4L / 4T=4 MLT⁻¹
               = 4 Magnitude of Impulse

therefore the magnitude of Impulse will become 4 times the initial Magnitude

Hope this helps you!!!
