Give reasons for the following statements-
‘Snow shoes’ are more effective than ordinary shoes for walking on snow.
Snowshoes are more effective than ordinary shoes for walking on snow, because the snow shoes are comparatively broader than the ordinary shoes. As we know that pressure is inversely proportional to the surface area which means that if area increases then pressure will decrease. So, the body weight will be distributed over a larger surface area of snow shoes and helps to walk effectively on snow.
