Answer:
a) 919 m
b) 183.8 m
Explanation:
140 calories = 140 * 4186 J/calorie = 586040 J
a)When the hiker climbs a mountain, this energy is converted to potential energy, which has the following formula
where m = 65 kg is the mass, g = 9.81 m/s2 is the gravitational acceleration and h is the height that he climbs
b) If only 20% of food energy goes into mechanical energy, then the actual potential energy is
586040 * 0.2 = 117208
Similarly, the height that he could climbs is
A climograph is a graphical representation of a location's basic climate. Clinograph is an instrument used to draw parallel lines to the inclined lines. It contains one adjustable wing or strip which can be adjusted to required angle. So, it can be termed as adjustable set square
