Answer:
force is of the LINEAR type
Explanation:
In simple harmonic movements the restoring force is of the Hooke e-force type, which has the form
F = - k (x-x₀)
where x₀ is the initial length of the spring.
Therefore we can see this force is of the LINEAR type
Answer: E) A) salt water.
Explanation:
E) In equilibrium, pressure exerts equally in all directions, so for a given depth, the pressure is the same for all points located at the same depth, and it can be written as follows:
p = p₀ + ρ.g.h, where p₀ = atmospheric pressure, ρ=fluid density, h=depth from the surface.
A) The buoyant force, as discovered by Archimedes, is an upward force, that opposes to the weight of an object (as it is always downward), and is equal to the weight of the volume of the liquid that the object removes, which means that is proportional to the density of the liquid.
As salt water is denser than fresh water, the buoyant force exerted by the salt water is always greater than the one produced by the fresh water, so objects will float more easily in salt water than in fresh water.
In the limit, it is possible that one object float in salt water and sink in fresh water.

Answer:
A. become flat becuase the volume decreases when the temperature decreases
Explanation:
<span>wavelength of an electron l = h/p = 8.7 x 10^-11
h --> Planck's Constant
m --> Momentum
Wavelength l = h/p = h/mv = > v = h/(m*l)
From the given values,
m = 9.1 x 10^-31 kg
l = 8.7 x 10^-11 m
h = 6.626x10^-34 Js
v = 6.626x10^-34/ ((9.1 x 10^-31)*(8.7 x 10^-11))
The velocity of electron v = 8.37x10^6 m/s</span>
