Answer:
There is no displacement.
Explanation:
Because the runner is running laps and returning to the original place, there is no displacement as displacement is relative to the change in location from the original position.
Hope this helps. . .

Since initial velocity is zero hence , u = 0
=> d = 1/2 * a * t2
on solving we get
d = 86.436 metres
Note ; Here Gravitational Acceleration is take as , g = 9.8 m/s2
This is known to be named supernova it a time in a stars life where it has reached it's final stage. It concludes that when stars explode supernova occurs or an tear in space is created know as a "blackhole". The star can only explode once it has survived over along period of time.
Answer:
Magnetic force, 
Explanation:
It is given that,
Speed of electron, v = 16748.76 m/s
Magnetic field, B = 0.0177 T
Angle between velocity vector and the magnetic field vector are make an angle of 59.24°. Magnetic force is given by :
So, the magnetic force on the electron is 
. Hence, this is the required solution.
Answer:
The bucket located in the direction opposite of displacement of the rod for balancing will be heavier.
Explanation:
Moment of a force is directly proportional to it's distance from the point about which rotation takes place. In the given case the man increases the lever arm(distance from point of rotation of the force) to balance the moment of the lighter bucket. Thus in the direction of the increase the lighter bucket will be placed.
