3) Distinguish between distance and displacement. (3)
3) The initial velocity and object is 20 m/s and it changes uniformly with time so that the object acquires a final velocity of 30 m/s after a gap of 10s . Calculate the acceleration (2)​​

Answer 1

Answer:

1:-) Melting Point - The temperature where solids Convrts into liquids

• 2:-) All matter is composed of very small particles which can exist independently.
• Particles of matter have spaces between them.
• Particles of matter are continuously moving.
• Particles of matter attract each other.

Answer 2

Answer:

1.The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium.

2.The characteristics of particles of matter are:

All matter is composed of very small particles which can exist independently.

Particles of matter have spaces between them.

Particles of matter are continuously moving.

Particles of matter attract each other.
