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:
strike-slip fault
Explanation:
A fault is a crack on the crust of the Earth where forces on the rocks causes the displacement of the rocks.
The movement of the crust determines the type of fault.
When rocks slip pass horizontally with respect to each other then it is called a strike slip fault. The crust moves towards each other causing horizontal compression. The displacement of the rock takes place parallel to the horizontal force.
Hence, the statement here is referring to the strike-slip fault.
Answer:
Explanation:
The current from the battery always flows from the positive terminal of the battery to the negative terminal of the battery.
If we connect a red coloured wire to the positive terminal of the battery and black coloured wire to the negative terminal of the battery, and then reverses the wire to their respective terminals, then there is no change in the direction of flow of current. It does not matter that which wire is connected to the particular terminal. The current always flow from positive to negative terminal of the battery outside the battery.
