The correct answer is - 1 cm/yr.
Alongside the western coast of South America, the Nazca plate and the South American plate are in a collision for several million years now, with the Nazca plate being the one that is subducting in this convergent plate boundary.
If the Nazca plate's focus has moved 1,000 km in the last 10 million years, than in order to get to the annual movement of the subduction we need to convert the km into cm first:
1 km = 10,000 cm
1,000 x 10,000 = 10,000,000
1,000 km = 10,000,000 cm
Than we need to divide the number of cm with the number of years:
10,000,000 / 10,000,000 = 1
And we get the result of 1 cm/yr.

The larger the mass of an object, the more force is required to move it.
D all of these I’m about 99% sure
Answer:
Option-C (The attractive forces are stronger in a solid)
Explanation:
The substance either exist as a Solid or Liquid depends upon on the following two factors;
ii) Kinetic Energy:
Greater the K.E of particles, greater will be the distance between the particles of a substance. In Liquids the K.E of particles is greater than the K.E of particles in Solid. Hence, the Liquid Particles separated by greater distance as compared to particles of Solids.
ii) Attractive Intermolecular Forces:
Greater the Attractive Intermolecular Forces between the particles of a substance, smaller will be the distance between the particles. As the distance between the particles in Solid state of substance are very small as compared to that of Liquids hence, it can be concluded that the Attractive Intermolecular Forces in Solids are stronger than Liquids.
