Assuming a typical efficiency for energy use by the body, how many slices of pizza must you eat to walk for 2.5 h at a speed of 5.0 km/h? assume that your mass is 68 kg, metabolic power of 68 kg individual walking at 5 km/h is 380 w, and the energy content of slice of pizza is 1260 kj.

2.7 Pizzas.

Explanation:

The power required to walk through 5km in 1 hour is 380W.

A watt is basically Jules per second, then we need to standardized this measurement to second.

5km/hr is equal to,

Walking by 2.5 hours is equal to a distance of,

The total energy required then would be,

Then we know that one pizza slice gives of energy, the total pizza needed are,

Then you need to buy 3 pizza.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

as technology advances, new experiments often expose problems in accepted theories. c
