Dark energy is what is causing the accelerating expansion of the universe. It can also be defined as the theoretical energy that counteracts or acts against gravity. Others also define it as a theoretical, new kind of dynamic energy field that fills space, but whose energy has an effect opposite to that of normal energy.

Answer:
We can increase the strength by increasing current in the wire or increasing the number of turns of the coil around an iron core .
Explanation:
The magnetic strength due to current carrying conductor carrying current I and having N number of turns is given by
B = 
is vacuum permeability .and its value is equal to 
.so from the above equation we can see that magnetic strength is directly proportional to the current through wire and no. of turns .
Answer:
the answer is C i didnt mean to put b lol
Explanation:
Density can be calculated using the following rule:
density = mass / volume
Since the density is given as 8 gm/cm^3 and the mass is given as 600 grams, therefore, all we need to do is substitute in the equation to get the value of the volume as follows:
8 = 600 / volume
volume = 600 / 8 = 75 cm^3
