Answer:when a white light falls on an object, the wavelength of maximum absorbance is removed by absorption and the remaining wavelength are reflected to the eye.

Explanation:Furthermore,this relationship entails that the color not absorbed is the color of the object,for example plants are green because they reflect green light and absorb red and blue light.

You hold glider A of mass 0.125 kg and glider B of mass 0.375 kg at rest on an air track with a compressed spring of negligible

umka2103 [35]

Answer:

0.2 m/s

Explanation:

$m_A$ = Mass of glider A= 0.125 kg

$m_B$ = Mass of glider B = 0.375 kg

$u_A$ = Initial Velocity of glider A = 0 m/s

$u_B$ = Initial Velocity of glider B = 0 m/s

$v_A$ = Final Velocity of glider A = 0.6 m/s

$v_B$ = Final Velocity of glider B

As linear momentum is conserved

$m_{A}u_{A}+m_{B}u_{B}=m_{A}v_{A}+m_{B}v_{B}\\\Rightarrow v_B=\frac{m_{A}u_{A}+m_{B}u_{B}-m_{A}v_{A}}{m_{B}}\\\Rightarrow v_b=\frac{0+0-0.125\times 0.6}{0.375}\\\Rightarrow v_b=-0.2\ m/s$

Magnitude of the glider B at this time is 0.2 m/s
