I’m pretty sure the width would be 15 be 4 to 2 is the same as 2 to 1
Thanks for including the graph!
Okay, so -
From examining the graph, we can see that for every minute the number of words increases by 40.
Now, since the x axis (the horizontal thingy kabob at the bottom) is time, and the y axis (the vertical thingy kabob) is the number of words - we can conclude that the answer is B!
Just remember that the value of the y axis is dependent on the value of the x axis. Also, note that x almost always represents time!
Answer:
Acceleration of the particle = 
Step-by-step explanation:
We are given the position vector of a particle moving in a circle of radius b units.
r(t) = b cos(ωt)i + b sin(ωt)j
Velocity , v =
= -bω sin(ωt)i + bω cos(ωt)j
The magnitude of velocity, v =
Squaring both sides,

Since
= 1

The acceleration towards the centre is called the centripetal acceleration and is given by
a = 
a = 
a = 
They both have the same number. The decimal point changed their values
Hope this helps! :)
