Q3. A student investigated the relationship between the force applied to a 2 points spring and the extension of the spring. This is the method used. 1. Hang a
spring from a rod.2. Hang a mass from the spring.3. Measure the extension
of the spring.4. Repeat steps 2 and 3 using different masses. (a) Give two
ways in which the appearance of the spring has changed.
Figure 1 shows a spring before and after a mass had been hung from it

Your answer
The extension of the spring is the distance between which two points on
the metre rule? Use letters from the diagram in Figure 1.
1 point

vapour or gas assuming atmospheriv pressure

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

mass and volume are the answers you are looking for

the inner core.

good luck: )
