A body moving with SHM has an amplitude of 10cm an a frequency of 100Hz. Find i. the period of oscillation, ii. the acceleration at the maximum displacement, iii. the velocity at the centre of motion.

The answer is a) taiga because taigas are cold

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero. 

Amicroscope, because these cells are so small that you would not be able to see them, or what they attack without it.
