Answer 1

moving (22) A theory describing objects at any sheeds even when sheeds offroaching the speed of light is known as " Theory of Relativity" given by Albert Einstein 64) The systematic study of motion using distance, speed, time and acceleration is known as "Kinematics" (25) A boy pushes the car. The car moves ereluctantly because can has inertia of rest +6) Change of velocity with time as "acceleration : is knoum At (27) The force per unit areal F/A) is known as "Pressure" (28) Visible region 30) wavelength.
