Answer:
this is because the light rays get reflected irregularly
Explanation:
Answer:
They are gaining energy, can move and slide past each other.
Explanation:
Because as ice melts, the molocules gain energy/heat which warm them up and are able to slide/move apart from each other.
Answer:
Rod 1 has greater initial angular acceleration; The initial angular acceleration for rod 1 is greater than for rod 2.
Explanation:
For the rod 1 the angular acceleration is
Similarly, for rod 2

Now, the moment of inertia for rod 1 is
,
and the torque acting on it is (about the center of mass)

therefore, the angular acceleration of rod 1 is


Now, for rod 2 the moment of inertia is


and the torque acting is (about the center of mass)


therefore, the angular acceleration
is


We see here that

therefore

In other words , the initial angular acceleration for rod 1 is greater than for rod 2.
Answer:
Non-uniform velocity as the laser light beam has got reflected by the mirror
And as the light got reflected there is a change in velocity making it non-uniform velocity
Answer: A. Resistance is directly related to length.
Explanation: Resistance is directly proportional to wire length. The longer the wire the greater resistance since there is more space for particles to collide. While resistance is inversely proportional with the cross- sectional area of a wire. The bigger the wire lower resistance.
