Question 4 (1 point) Sophia is working in her garden. She made two trips with her wagon along the same path to haul supplies. The first held 3 bags of soil, while the second load had 5 bags. Assuming they accelerated the same, which required more force to move. The one with 5 bags. The one with 3 bags. An equal amount of force is required for both. Neither will take any force because the wheels reduce friction.​

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.
