Answer:
Surface tension is a fundamental property of the surface of liquid. Surface tension is responsible for the curvature of the surfaces of air and liquids. Surface tension is responsible for the ability of some solid objects to “float” on the surface of a liquid.

You have:
A1= 0.15 m²
A2=6.0 m²
F1=130.0 N
To solve this problem you must use the pressure formula, as below:
P1=P2
F1/A1=F2/A2
Then, you have:
m2=A2xF1/A1xg
g=9.81 m/s² (This is the acceleration of gravity)
When you substitute the values in m2=A2xF1/A1xg, you obtain:
m2=(0.60 m² x 130.0 N)/(0.15 m² x 9.81 m/s²)
The answer is:
m2=530 Kg
Answer:
It depends on the size of the star but I think it's B
Explanation:
If the star is massive, it will eventually explode (supernova) and if it is a star with a high mass, the core of it will form a neutron star and if it is very massive the core will turn into a blackhole
Answer:
D. It is relatively inert.
Explanation:
