Torque will produce rotation
Answer:
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,
<em>Then you need to buy 3 pizza.</em>
