Find the momentum of a 25kg object going 4 m/s.

Given data

Find momentum (p) = ?

mass (m) = 25 Kg ,

velocity (v) =4 m/s

         momentum (p) = m.v

                                  = 25 × 4

                                  = 100 Kg. m/s

Momentum of the object is 100 Kg. m/s

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
