Answer:
Absolute magnitude
Explanation:
The brightness a star would have if it were at 10 pc from Earth is called Absolute magnitude.
See the bullet will have a parabolic path both the components should be solved separately thus the y-axis path will be a free fall as there won't be any velocity vector there
so we get
√2h/g= t
√2*78.4/9.8 = t
thus t= 4sec
it means it would take 4 sec to travel 1500 metres
so 1500/4 = 375 m/s would be velocity !
Answer:
No, it is not magnetized.
Explanation:
Bar B does not necessarily have to be magnetized before it can be attracted to a magnet. It just has to be a magnetic material such as Iron.
If bar B were magnetized, it could either be attracted or repelled by the magnet since this would depend on the side of the pole of bar B facing it.
Since we are not given any information about bar B other than it is attracted to the magnet, it is thus not magnetized.
