A high jumper of mass 60kg consumes a meal of 3.00 x 10 ³ kcal prior to a jump. If 3.3% of the energy from the food could be converted to gravitational potential energy in a single jump, how high could the athlete jump?
Imagine you are in line to enter a brand new shopping mall and you are very much excited because after months of waiting, you will now be able to enter shopping malls after the pandemic. The stores comprising the mall are very popular. These stores include Converse, Gucci, Jansport, Fendi and all other popular brands, and so the demand to enter is very high. Security guards only allow one person through the doors at a time. As a result, the line and the wait are quite long. To add to the chaos, the waiting crowd is made mostly of frequent shoppers who are growing very impatient and holding up the line with their constant complains. Together, these factors affect the flow of customers into the shopping mall, just as electric resistance affects the flow of charges through a current.
1. What makes less resistance favorable in a circuit?
2.If the guard formed two adjacent lines to allow two people into the mall at a time, we would expect the mall to be filled up faster. If we encased these…
One ounce of a well-known breakfast cereal contains 99 Calories (1 food Calorie = 4186 J). If 2.4% of this energy could be converted by a weight lifter's body into work done in lifting a barbell, what is the heaviest barbell that could be lifted a distance of 2.0 m?

- The recommended daily caloric intake is 2000 calories (8,400,000J). This is because this is the same value for how much the average body loses to heat and work in a typical day (your change in energy is zero because you take in the same amount of energy you lose). A) If you lose a total of 8,400,000J (Qout+W=total lost), but consume 1200 calories of food (5,000,000J), what would your change in energy be? B) Assuming your change in energy is negative (hint-it should be), where does your body get the extra energy to maintain it's temperature?arrow_forwardA woman violates her diet by eating a cookie that contains 100 Calories.
