Answer:
The linear acceleration of Q is twice as great as the linear acceleration of P.
Explanation:
As we know that disc is rotating about the vertical axis with constant angular speed
So here we can say that the acceleration of any point on the disc is given as
where we know that
r = radial distance of the point
also for the linear speed of the point on the disc is given as
so we know that
distance of point Q is double the distance of point P
so we will have
Answer:
a) Wavelength .
Explanation:
Visible light is comprised of all the seven colors Violet , Indigo , Blue , Green , Yellow and Red .
Color depends up on the wave length of the light .
For example a red ball appears red because it absorbs wavelengths of all the other colors and reflects only wavelengths corresponding to red color.
Answer:using Newton third law
Let initial velocity of block be u1=3m/s
Mass of moving block m1 =1kg
Final velocity of block =V
Mass of stationary block m2= 4kg
Since they stick together, their final velocity will be the same.
m1u1 + m2u2=(m1+m2)v
(1*3)+(0*4)=(1+4)v
3=5v
Divide both sides by 5
V=0.6
Final velocity is 0.6m/s
