Answer: 10.8 g
Explanation: Density = mass/ volume
So, Mass = density * volume = 0.9 g/ml * 12 ml = 10.8g
Answer:
d = 27.7 m
Explanation:
Here the car is driving on the inclined plane
So here we can say that work done by the gravity and work done by friction is equal to change in kinetic energy of the system
So here we can write it as
now we have
m = 1700 kg
Each magnet has a north pole and a south pole. We know that, from having played with bar magnets in our childhood, that a magnet's north pole will repel another magnet's north pole and attract its south pole.
From this diagram it is easy to see that the two lower bar magnets not only repel each other, but they are quite attracted to each other since their north and south poles are close together.
Therefore the region between the lower two magnets has the least force of repulsion.
