Answer:
density ρ = mass / volume
ρ = 100 g / 11.2 cm^3 = 8.93 g/cm^3
Probably copper because a value given for Cu is 8.89 g/cm^3
1. they all come from the clouds 2.they are all formed by precipatation. hope this helps enjoyyyyyy!!!!!!!!!!!!!
Answer:
1: 6.637e-13 N
2: 6.637e-09 N
3: 1.335e-08 N
4: 1.335e-08 N
5: 1.456e-06 N
6: 5.839e-07 N
7: 6.673e-11 N
I'd suggest double checking these if you can.
Explanation:
Each of these you can answer by plugging the numbers into the equation
G is the gravitational constant 6.673×10⁻¹¹ N m² / kg²
So the first one would be:
I'm not going to run through showing all calculations for the rest, as you're in a rush, so to whip through them
2: 6.637e-09 N
3: 1.335e-08 N
4: 1.335e-08 N
5: 1.456e-06 N
6: 5.839e-07 N
7: 6.673e-11
Pardon the lack of superscript, I just punched these into a python console to calculate them.
