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 10 g mass is hung on it?
- What is the mass hung on the spring when its length is 59 cm?
- What is the length of the spring when it is not stretched?
- How many centimetres is the spring stretched after a mass of 5 g is hung on it?
(a)
Length of the spring when a 10 g mass is hung on it = 56 cm
(b)
Mass hung on the spring when its length is 59 cm = 15 g
(c)
Length of the spring when it is not stretched = 50 cm
(d)
Length of the spring that is stretched after a mass of 5 g is hung on it
= 53 - 50
= 3 cm
Answer(s): (a) 56 cm; (b) 15 g; (c) 50 cm; (d) 3 cm
