Answer:
The second box
Explanation:
Work done is the force applied to move a body through a particular distance.
Work done = Force x distance
For the first box:
Weight = 12N
Distance = 1m
Work done = 12 x 1 = 12J
For the second box;
Weight = 1000N
Distance = 30cm = 0.3m
Work done = 1000 x 0.3 = 300J
The second box has a higher work done.
Answer:
D. Copper
Explanation:
Copper has the best electrical conductivity of any metal, except silver. A good electrical conductivity is the same as a small electrical resistance.

Answer:
It will keep moving at the same speed.
Explanation:
In space, there is vacuum which means that there is no air resistance. Since we remain in the state of free fall in the space, the impact of gravity is also negated on the friction. So the friction will be zero.
As per Newton's first law, we will need to apply external force to change the state of motion of a body. In this case when he let go of the lunch box it has a certain speed. This speed will not changes as there is no friction and no acceleration. So the box will keep on moving with the same speed.
It is difficult for astronomers to find object like planets and asteroids because it takes a lot of time to verify the objects locations and what surrounds a certain object in order to prove and be precise of its location
