Answer:
Extension is 12.14m
Explanation:
mass of ornament=42g,weight of ornament=mg=42*9.8=411.6
Force constant(k)= 33.9N/m
F=ke
e=F/k
F is force, e is extension
F=weight of ornament
e=411.6/33.9
e=12.14m
Particles in the liquid state of matter are close together, yet free to move around one another
Gpe= 90* 9.81 * 15 = 13243.5 Joules
KE= 13243.5 =1/2 m v^2
v^2= 295.3
v= 17.2 m/s
Answer:
Explanation:
When a liquid is heated, the particles are given more energy. They start to move faster and further apart. At a certain temperature, the particles break free of one another and the liquid turns to gas. This is the boiling point.
