Answer
given,
mass of block (m)= 6.4 Kg
spring is stretched to distance, x = 0.28 m
initial velocity = 5.1 m/s
a) computing weight of spring
k x = m g
k = 224 N/m
b) 
c) 
d) 
e) 
A = 0.682 m
Force =
=
F = 94.20 N
<span>It is important to determine their location before operating on an unfamiliar body of water because they are often difficult to spot, even with local charts. If you don't know what you're doing you can get stuck and that can be a huge problem, so it's necessary to know what you're doing and where they are located.</span>
Z - Gamma Rays
X - Visible Light
Gamma rays are heavily produced in the core of the sun but are diluted before they reach the surface (Z). And the surface is the only thing the human eye can see (X).
<span>The total mass is always conserved in a chemical reaction because mass cannot be destroyed nor created. This is expressed in the law of conservation of mass. Atoms in a reaction cannot form another type of atoms which has different properties than the original element. It can only exchange electrons which is responsible for bonding.</span>
No, it's mass remains the same. It's attraction to the planets center AKA gravity changes.
