Answer:
Doubled
Explanation:
F = (kq1q2) / r^2
F and q (Either q1 or q2) are directly proportional, so double the charge would also double the electruc force between the charges.
Of the gravitational pull and other things like mass. Planet earth it,s self as you said sir.
Answer:
Gold
Explanation:
Given:
Mass of sample = 63.5 g
Mass of water = 60.2 g
Find:
Object
Computation:
Mass of water displaced = 63.5 g - 60.2 g
Mass of water displaced = 3.3 g
So, volume in water = 3.3 cm³
Density = Mass / Volume
Density = 63.5 g / 3.3
Density = 19.24
So,
Object ,must be gold.
