Answer:
the awnser is Cart A.
cart A has a mass of 14 kg but is pushed with 25newtons of force and 25 is 11 more than 14 and it just kind of makes sense.
and cart B has a mass of 12kg and is pulled with 19newtons and 19 is 7 more than 12.
Hope this helps!
H2So4 is a strong acid and a strong electrolyte which means that when this dissociates in water, the dissociation process is complete. The first dissociation is
H2 SO4 = H + HSO4-
This can further release H+ and dissociate SO4- instead already
It has 5 digits so the exponent of 10 will be 4:-
61,103 =
6.1103 x 10^4

Answer:
1.84 g/cm³
Explanation:
A flask has a mass of 78.23 g when empty and 593.63 g when filled with water. The mass of water is:
m(water) = 593.63 g - 78.23 g = 515.4 g
The density of water is 1.00 g/cm³. The volume of water (and the flask) is:
515.4 g × (1 cm³/1.00 g) = 515 cm³
When the same flask is filled with concentrated sulfuric acid, H₂SO₄, its mass is 1026.57 g. The mass of H₂SO₄ is:
m(H₂SO₄) = 1026.57 g - 78.23 g = 948.34 g
948.34 g of sulfuric acid occupy a volume of 515 cm³. The density of sulfuric acid is:
ρ = 948.34 g / 515 cm³ = 1.84 g/cm³
