The answer should be flammability
Energy consumed in doing the work = 300 Joules
Force applied on the object = 75 N
Let the distance moved by the object be d.
Work done by the force is determined by the force applied and the displacement happened in the direction of the force applied.
Work done = Force x displacement
300 = 75 x d

d = 4 m
Hence, the maximum distance moved by the object = 4 meters
We know that displacement is the length of straight line joining the initial position with the final position. as lisa walks around the block once, she comes back to her initial position here she started from, hence the initial and position of lisa is same. so her displacement is zero.
We know that distance is the length of the actual path followed by object between initial and final position. As lisa walks around the block once, she travels 1 mile. hence the distance traveled by lisa is 1 mile.
displacement : 0
distance : 1 mile
The radiation that was emitted is still "visible"
The universe is still expanding
Dark matter could only be crated by an atomic collapse big enough to create or destroy a universe
