That's not true people that have a broken leg use crutches and the constant lifting of their own body weight will help them gain muscle
Explanation:
Below is an attachment containing the solution.
Answer:The main formula is v² = u² + 2as
Explanation:
S=½(u +v)t
t = v+u/a
S=½(v-u)(v+u/a)
S=½v²+uv-uv-u²/a
2as=v²-u²
Answer:
The width of the slit is 0.167 mm
Explanation:
Wavelength of light, 
Distance from screen to slit, D = 88.5 cm = 0.885 m
The distance on the screen between the fifth order minimum and the central maximum is 1.61 cm, y = 1.61 cm = 0.0161 m
We need to find the width of the slit. The formula for the distance on the screen between the fifth order minimum and the central maximum is :

where
a = width of the slit


a = 0.000167 m

a = 0.167 mm
So, the width of the slit is 0.167 mm. Hence, this is the required solution.
