Answer:
PART A
In a solid
The attractive forces keep the particles together tightly enough so that the particles do not move past each other. ... In the solid the particles vibrate in place. Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container.
In a liquid
Particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.
A gas
The particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster.
PART B
The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces. The more particles that hit the walls, the higher the pressure.

Answer:
Explanation:
we know angular velocity in terms of moment of inertia and angular speed
ω .... (1)
moment of inertia of rod rotating about its center of length b
........ .(2)
using v = ωr
where w is angular velocity
and r is radius of rod which is equal to b
so we get 2v = ωb
ω = 2v/b ................. (3)
here velocity is two time because two opposite ends are moving opposite with a velocity v so net velocity will be 2v
put second and third equation in ist equation
×
so final answer will be

<h3>Information technology Importance</h3>
- Information technology helps to build and grow the commerce and business sector and generate maximum possible output. The time taken by different sectors to generate business is now minimised with an advancement in Information technology. It provides electronic security, storage, and efficient communication.
The Lamborghini Diablo sports car can accelerate from 0.0
km/hr to 99.2 km/hr in 4.0 seconds. What is the acceleration of this car? Give
your answer in units of kilometers per hour/sec.
To find the acceleration of the car we have to
<span><span>
1. </span>First determine
the suitable formula for this word problem. Which is</span>
<span><span>a. </span>A=vf-vi/t</span>
Given are:
Vf=99.2 km/h
Vi= 0.0 km/h
T= 4.0sec
Solution:
A= 99.2 km/h – 0.0km/h / 4.0 sec
A = 99.2 km/h / 4 sec
A = 2.8 km/h/sec
