what is aceleration |
|
Answer» for Yogita, Anand Singh, .. . thanks to you all Formula for it a=v-u/t Rate of change of velocity with respect to time A=change in velocity /change in time Rate of change of velocity is called acceleration.a=v-u/t Acceleration is a measure of the change in the velocity of an object per unit time and mathematically it is given asAcceleration = Velocity change/time takenf the velocity of an object changes from an initial value u to the final value v in time t, the acceleration a is given by,a = (v-u)/tand this kind of motion is called accelerated motion. |

Why is the cell called the structual and functional unit of life |
|
Answer» This is not the correct answer..Cell is the basic structural and functional unit of life as every living thing is made up of one or more than one cells.It is the structural unit as cells are first organised into tissues and tissues are organised to form organs and organs are grouped into organ systems.And the functional unit because it performs the basic functions like respiration, nutrition, reproduction etc. which are essential for our survival As all the living organisms are made up of cells thats why it is known as the structural unit of life and their are different cells to perform different functions in our body thats why it is known as the functional unit of life Chill pill. Cell is the basic unit of all life structures( kidney, heart). Cell is the basic unit of all the organ system( skeletal system, neural system) whose functions are the reason for our existance.9990972508wp.
