Answer:
A CD.
Explanation:
A compact disc (CD) is a small digital-optical disc that is used to store computer data using a laser beam.
The compact disc is able to store digital data because it is made up of a polycarbonate (a tough-brittle plastic) with one (1) or more metal layers.
Hence, the data stored in a compact disc cannot be scrambled by a magnet because it isn't made of a magnet or doesn't have a magnetic field.
Answer:

Explanation:
GIVEN,
mass of electron = 9.1 x 10 kg
Radius = 5.3 x 10 m
pulling force = 8.2 x 10 N
Required centripetal for (Fe) for circular motion will be provided with electrical force (F)




ω = 4.12 x 10¹⁶ rad/s


Answer:
I) You walk barefoot on the hot street and it burns your toes.
II) When you get into a car with hot black leather in the middle of the summer and your skin starts to get burned.
Explanation:
In conduction mode of heat transfer we know that the energy is transferred from one system to other system due to direct contact of two bodies
Here due to this direct contact the energy is transferred via a given solid or liquid medium
In this type of heat transfer medium particles will remain in its own position only the energy is transferred.
So here we can say the correct answer will be
I) You walk barefoot on the hot street and it burns your toes.
II) When you get into a car with hot black leather in the middle of the summer and your skin starts to get burned.
