The line graph shows the length of a spring when various masses are hung on it.
- What is the length of the spring when a 80 g mass is hung on it?
- What is the mass hung on the spring when its length is 38 cm?
- What is the length of the spring when it is not stretched?
- How many centimetres is the spring stretched after a mass of 100 g is hung on it?
(a)
Length of the spring when a 80 g mass is hung on it = 56 cm
(b)
Mass hung on the spring when its length is 38 cm = 40 g
(c)
Length of the spring when it is not stretched = 20 cm
(d)
Length of the spring that is stretched after a mass of 100 g is hung on it
= 65 - 20
= 45 cm
Answer(s): (a) 56 cm; (b) 40 g; (c) 20 cm; (d) 45 cm
