- A Car accelerates from rest by 4 m/s² for 10 sec 8 Continue 4 its motion for the next to sec by acceleration of 2m/st. Find the displacement trouedied by the car,

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
