Answer:
The work done is 202.50Nm
Step-by-step explanation:
Given



Required
The work done
First, we calculate the spring constant (k)




So:


The work done using Hooke's law is:

This gives:

Rewrite as:

Integrate

This gives:




Convert to Nm


Answer:
I think it's 24, but if it's not then I'm really sorry.
Step-by-step explanation:
S + a = 722
s = 72 + a
(72 + a) + a = 722
2a + 72 = 722
2a = 722 - 72
2a = 650
a = 650/2
a = 325 <== adults
s = 72 + a
s = 72 + 325
s = 397 <== students
Answer:
5 miles=8 km
=)1 mile=8/5 km=1.6 km
=)40 miles=1.6×40=64 km
So, 40 miles is 64 km.
Step-by-step explanation:
we know that
Two angles are Complementary when they add up to
degrees and two angles are Supplementary when they add up to
degrees
f the exterior sides are opposite rays, then a straight line forms and you have the two angles add to
degrees
So
the angles are supplementary and not complementary
therefore
the answer is the option
Never
