For a printed circuit board, there are a total of thirteen different locations to attach an electronic component. (a) Assuming there are five different electronic components to be placed on the circuit board, in how many different ways can these five components be placed on the circuit board? 7 8 1 3 6 12 2 9
(b) Now, assuming the circuit board has only five different locations to attach a component. How many different ways there are to place five out of thirteen different electronic components on the circuit board? Comment on the number of possibilities under (a) and (b).

answer; the correct answer is technician a; ///100%good luck

the answer is to check all of them! they all apply well at least i think so!

true tan speed = ang vel x radius

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
