Answer:
The graph shows direct proportion because it is a straight line
through the origin.
Explanation:
The answer is (B. The study of Matter and Energy) but technically you could consider physics all of these as engineering is based on physics and that would be the study of inventions, chemistry and biology were both discovered because of physics, and physics invokes more math than any other subject as it applies math to the entire Universe.
In projectile motion horizontal motion has zero acceleration and when there is no air resistance acting on the object the motion will be uniform. Motion in the vertical direction is accelerated downwards to to the acceleration due to gravity
Answer:
Melting occurs when a solid is heated and turns into a liquid. The particles in a solid gain enough energy to overcome the bonding forces holding them firmly in place.
During the melting point, the particles start to move about, staying close to their neighboring particles, then move more freely.
Explanation:
As a substance melts and goes from a solid to a liquid state, the kinetic energy of the molecules increases and moves faster, and separates further away from each other. This is why a liquid can fill the shape of its container, where a soild has a fixed shape.
