Answer:
there doesnt seem to be much information, but from what it looks like it looks like it is 20?
Answer:
From the analysis W1=W2.
they are directly related
Step-by-step explanation:
the work-done in stretching a spring can be expressed as

where k= spring constant
x= change on length of spring
Hence for W1
Given data
x= 34-24= 10 cm
solving in terms of k we have

Hence for W2
Given data
x= 44-34= 10 cm
solving in terms of k we have

Answer:
First, find two points on the graph:
- (x₁, y₁) = (0, 2)
- (x₂, y₂) = (2, 8)
Slope = 
16 + (-3) = 16 - 3 = 13
Answer:
The angle that the line makes with x-axis of of 64.3º.
Step-by-step explanation:
Equation of a line, and angle with the x axis:
The equation of a line has the following format:

In which m is the slope.
The angle that the line makes with the x axis is given by the angle which has tangent m, that is,
.
In this question:
We have that
. So

The angle that the line makes with x-axis of of 64.3º.
Answer:
9
It is 9 because 9 is the only number that multiplied by itself is 81.
