i just took the test
Answer:
Explanation:
Given
magnitude of vector=8.7 m/s
Direction 
Therefore vector x component is 
=-2.104
i.e. it is acting in negative x axis
vector y component
Therefore it lies in negative y axis
Judging vector x and y component
It lies in third quadrant

Korean War: 25 June 1950 – 27 July 1953
Many then believed that the conflict was likely to soon escalate into a full-scale war between the three countries, the US, the USSR, and China. CBS war correspondent Bill Downs wrote in 1951 that, "To my mind, the answer is: Yes, Korea is the beginning of World War III.
Explanation:
Answer:
The neddle of the galvanometer will move to the right at a faster speed.
Explanation:
Given:
The north pole of a bar magnet is moving towards a solenoid and the needle of the galvanometer moves to the left.
When a bar magnet has a relative deisplacement with respect to a solenoid, then it will induce some emf within the solenoid according to Faraday's law. When the north pole is moving towards the solenoid it will induce a current.
When the bar magnet is moving away from the solenoid at a faster speed, the rate of change of flux in the solenoid is faster. So the induced current will change in faster way, but in the opposite direction.
Thus, the neddle of the galvanometer will move to the right at a faster speed.
