The Renaissance, was the rebirth to science as well as many other advancements
The answer is C. The mass of the platinum sample is greater than the mass of the lead sample. As I explained in a previous answer, if they are the same volume, but one is heavier, then it must be more dense. In this particular example, the platinum is more dense than the lead, and therefore has more mass.
Answer:
156.96 N
Explanation:
F=ma where m is the mass and a is acceleration
Substituting 16 Kg for m and 9.81 m/s2 for g then
F=16*9.81= 156.96 N
Answer:
The answer to your question is: Ke = 3000 Joules
Explanation:
Data
mass = 15 kg
speed = 20 m/s
Kinetic energy = ?
Equation


Ke = 3000 Joules
The change in the Gibb's free energy per mole (G) is 1.96 J.
The given parameters:
- Density of the ice, ρ = 917 kg/m³
- Initial pressure, P₁ = 1.0 bar
- Final pressure, P₂ = 2.0 bar
- Temperature, T = - 10 C
- Mass of water = 18 g
The change in the Gibb's free energy per mole (G) is calculated as follows;

where;
V is the volume of the ice

Change in pressure;

The change in the Gibb's free energy per mole (G);

Thus, the change in the Gibb's free energy per mole (G) is 1.96 J.
