There are 8 marks on the line and the first line is 3 long while the second is 2 long
c. 3/8+2/8=5/8
Answer:
2 is the constant of proportionality in the equation y = 2x .
Step-by-step explanation:
Definition of constant of proportionality
When two variables are directly proportional to each others .
Let us assume that u and v .
u \propto vu∝v
Than the equation becomes u= kv
Where k is called the constant of proportionality .
Thus in the question x and y are proportional variables .
i.e
y \propto xy∝x
y = kx
Where k is called the constant of proportionality .
Compare the equation y = kx with y=2x .
Thus
k = 2
Therefore 2 is the constant of proportionality in the equation y = 2x
the explanation is not mine only the answer
Answer:
(a) 
(b)
units.
(c) m = 10 units
Step-by-step explanation:
Force (F), mass (m) and acceleration (a) are related by the equation F = ma.
(a) We have to solve this equation for a.
So, F = ma ........ (1)
⇒
..... (2) (Answer)
(b) If F = 1 units and m = 5 units, then from equation (1), we get
units. (Answer)
(c) If F = 25 units and a = 2.5 units.
Then from equation (1), we get,
units. (Answer)
