Answer:

20N

Explanation:

The force (Hooke's Law) is proportional to the deformation. To extend the spring 4 times longer, you will need 4 times the force. In total, 20 N

Answer: 4Joules

F=-kx

E=1/2kx^2

5N=-k(.01m)

k=50N/m

E=1/2kx^2

E=1/2(50N/m)(0.4m)^2

E=4Joules

Liquid water has surface tension, has a high specific heat, and functions effectively as a solvent for polar covalent and ionica
MrRissso [65]

Answer:

The property to form polar covalent bond and hydrogen bonds

Explanation:

Liquid water exhibits the property of surface tension, functions as solvent for ionic and polar covalent bonded molecules and have high specific heat.

All these properties can be credited to the property of water to form hydrogen bonds with liquid water molecules where the hydrogen bonding results when hydrogen atom of a water molecule is attracted to a more electro negative oxygen atom of other water molecule in the neighborhood while polar covalent bond formation results in the the water molecule as it is a polar covalent molecule as it contains hydrogen atom and an electronegative oxygen atom which results in the charge distribution in the molecule.

In ‘static equilibrium' the force pushing out against the inward pull of gravity is
Gemiola [76]
If you are referring to stars, the answer would then be pressure from the nuclear reactions 

The thermal pressure that pushes outward and against the pull of gravity in a star is caused by the nuclear reactions that is happening within the stars core. A lot of energy is released during these reactions which produce thermal pressure. The pressure then pushes outward.

You throw a rock horizontally out of a 7th story window. You time that it takes 3.7 seconds to hit the ground, and measure that
Nady [450]
Since we are only looking at the vertical height, we can use the free fall equation to find the height:
h = 0.5*g*t^2, where h is height in m, g is acceleration due to gravity (9.81 m/s^2), and t is time in seconds
h = 0.5*(9.81 m/s^2)*(3.7 s)^2
h = 67.15 m
Therefore, the 7th floor window is 67.15 m above ground level.
