Answer:
a = L
b = MT^(-1)
c = LT^(-1)
k = MT^(-2)
f = MLT^(-2)
S = T^(-1)
Step-by-step explanation:
x (0) = a
x is denoted by displacement in vibration analysis hence attains units of x.
Hence, a = L
b is the damping coefficient:
x'(0) = c
dx/dt = velocity hence c attains the units of velocity
c = LT^(-1)
Coefficient k is the stiffness:
Coefficient f is the magnitude of the exciting force
Coefficient S is the angular frequency
angular frequency is displacement in radians per seconds; hence,
S = T^(-1)
Answer:
1 1/2
Step-by-step explanation:
because when you divide 7.5 by 5 you get 1.5
50%. students (in percent) who passed the second exam also passed the first exam.
Let's imagine that there are 100 kids in the teacher's class. We know that 40 of them passed BOTH tests, and 80 passed the second test.
Because if they weren't, they wouldn't have passed the first test and consequently wouldn't have passed both, we can be sure that the group of students who passed BOTH tests is only made up of the 80 who passed the second test.
Thus, both tests were passed by 40 of the 80 pupils who passed the second one:
40/80 = 1/2 = 50%.
