Write properties of solutions |
| Answer» Properties of a solution:\tA solution is a homogeneous mixture.\tThe particles of a solution are smaller than 1 nm in diameter. So, they cannot be seen by naked eyes.\tBecause of very small particle size, they do not scatter a beam of light passing through the solution. So, the path of light is not visible in a solution.\tThe solute particles cannot be separated from the mixture by the process of filtration. The solute particles do not settle down when left undisturbed that is, a solution is stable. | |

Diffrence between acceleration and velocity |
|
Answer» Velocity-speed of the object in a given direction is called velocityAcceleration-the rate of change of velocity in per unit time is called acceleration Velocity is the speed of an object in a given direction WHILE acceleration of an object is the change in velocity per unit time. Acceleration means the change in velocity it means that body velocity will increase or decrease is called acceleration. Where as velocity means distance covered with respect to time in definite direction. Example-a car moving towards east Speed in a direction is called velocity . While The rate of change in velocity is called acceleration. |

Explain Ist IInd and IIIrd equation of motion |
| Answer» First Equation of Motion:The final velocity (v) of a moving object with uniform acceleration (a) after time, t.Let, the initial velocity = u.Final velocity = v.Time = t Acceleration = a________________________________________We know that, Acceleration (a) =Change in velocityTime taken=Change in velocityTime taken⇒a=Final velocity-Initial velocityTime taken⇒a=Final velocity-Initial velocityTime taken⇒a=v−ut⇒a=v-ut⇒at=v−u⇒at=v-u⇒at−v=−u⇒at-v=-u⇒−v=−u−at⇒-v=-u-at⇒v=u+at⇒v=u+at ---(i)This equation is known as first equation of motionSecond Equation of Motion:Distance covered in time (t) by a moving body.Let, Initial velocity of the object = uFinal velocity of the object = vAcceleration = aTime = tDistance covered in given time = sWe know that,Average velocity =Initial velocity+Final velocity2=Initial velocity+Final velocity2∴ Average velocity =u+v2=u+v2 ----(ii)We know that, Distance covered (s) in given time = Average velocity x TimeOr, s = Average velocity x Time -----------------(iii)After substituting the value of average velocity from equation (ii) we get⇒s=u+v2×t⇒s=u+v2×t________________________________________After substituting the value of ‘v’ from first equation of motion we get,⇒s=u+(u+at)2×t⇒s=u+(u+at)2×t⇒s=u+u+at2×t⇒s=u+u+at2×t⇒s=2u+at2×t⇒s=2u+at2×t⇒s=2ut+at22⇒s=2ut+at22⇒s=2ut2+at22⇒s=2ut2+at22⇒s=ut+at22⇒s=ut+at⇒s=ut+12at2⇒s=ut+12at2 ----(iv)The above equation is known as Second equation of motion.Third Equation of Motion:The third equation of motion is derived by substituting the value of time (t) from first equation of motion.We know from first equation of motion, v=u+atv=u+at⇒v−u=at⇒v-u=at⇒at=v−u⇒at=v-u⇒t=v−ua⇒t=v-ua -----(v)__________________________________ | |
