Answer:
Final angular velocity is 35rpm
Explanation:
Angular velocity is given by the equation:
I1w1i + I2w2i = I1w1f -I2w2f
But the two disks are identical, so Ii =I2
wf can be calculated using
wf = w1i - w2i/2
Given: w1i =50rpm w2i= 30rpm
wf= (50 + 20) / 2
wf= 70/2 = 35rpm
Answer:
The direction of a magnetic field is by convention, the direction towards which the northpole of a compass needle points when placed under the influence of the magnetic field at any location.
Explanation:
A Magnetic field is a vectorial force field.
As such, the direction of such a field is very important when describing it.
The direction of a magnetic field is by convention, the direction towards which the northpole of a compass needle points when placed under the influence of the magnetic field at any location.
The direction of a magnetic field may be further described using magnetic field lines .
PS: An important feature of magnets is that like poles repel and unlike poles attract. Just an additional detail.
