3,89,988 cm/min is the linear velocity
Given,
Diameter of CD = 12 cm
So, Radius of CD = 6 cm
CD is spinning at 10350 rev/min
Firstly , convert rev/min into rad/min
1 rev = 2π radians
10350 rev/min = 10350 × 2π
= 64998 rad/min
Formula used,
where,
is the Linear velocity
is the radius
is the angular velocity
= 6 cm × 64998rad/min
= 3,89,988 cm/min
Thus, linear velocity for any edge point of a 12-cm-diameter CD (compact disc) spinning at 10,350 rev/min is 389988 cm/min.

Answer:
kinetic energy at that point is 3500 MJ
Explanation:
Given data
potential energy = 5000 MJ
kinetic energy = 4500 MJ
satellite’s potential energy is 6000 MJ
to find out
kinetic energy
solution
we know that total energy is sum of kinetic energy and potential energy
so kinetic energy will be
kinetic energy = total energy - potential energy ................1
here
total energy = 5000 + 4500 = 9500 MJ
so now put all value in equation 1
kinetic energy = total energy - potential energy
kinetic energy = 9500 - 6000 = 3500
so kinetic energy at that point is 3500 MJ
Answer:
These four are rotary, oscillating, linear and reciprocating. Each one moves in a slightly different way and each type of achieved using different mechanical means that help us understand linear motion and motion control.
