A man on a bench will exert the greatest pressure on the bench when he
lies flat on his back
lies flat on his belly
stands on both feet
stands on the toes of one foot

hence, pressure increases when the areas decreases.
0.795m
0.625m
0.335m
0.125m
Correct answer is A
n = 200, S = 132 rev/min, v = 350m/s\(^2\)
| f | = | ns | = | 200 | × | 132 | rev
min |
× | 1min
60s |
= | 440Hz |
| λ | = | v
f |
= | 350
440 |
= | 0.795m |
