The behavior of light makes it
possible for you to see a spectrum of colors in a spray of water on a sunny day
is refraction. The refractive index of a medium is dependent on the wavelength
and hence light of different wavelength undergo refraction by different angle
which causes the splitting of light beam in different color.
Atoms are made up of three particles: protons, neutrons and electrons. Protons and neutrons are heavier than electrons and reside in the center of the atom, which is called the nucleus.Jun 5, 2013-livescience.com
Answer:
unmmm u can say that it is going mt 15s
Impulse = Ft = Δmv, where F is the average force, t is time, m is mass and v is velocity.
Δmv = m(v₂ - v₁) = 0.2 * (3 - (-4)) = 0.2 * 7 = 1.4
Solve for F.
