Answer:
D) Magma with low viscosity
Explanation:
Pressure is needed for a volcanic eruption to occur. When the viscosity or thickness of the magma is low or absent, only a limited amount of pressure can build within the magma chamber, resulting in a less than spectacular eruption.
A rope held tightly posses elastic potential energy. when the rope is held tightly, it gets stretched by some amount and in a way the rope gets deformed. The rope tends to get its original shape back when the rope is released. some work is done to deform or stretch the rope against the restoring force between the particles and this work done reflects as elastic potential energy.
Elastic potential energy.
Answer:
According to this law, the force exerted between two point charges
i) is directly proportional to the product of their strengths.
ii) is inversely proportional to the square of the distance between them. and
iii) is inversely proportional to the absolute permittivity of the surrounding medium.
This is known as Coulomb's Law.
Answer:
846.72 J
Explanation:
Given that,
The mass of the package = 36 kg
It is raised through a vertical height of 2.4 m.
Initial potential energy of the package will be 0 as it was at ground.
The change in gravitational potential energy is given by :
Hence, the change in gravitational potential energy is 846.72 J.
