Answer:
23.63 °C
Explanation:
= mass of water = 0.250 kg
= initial temperature of water = 20.0 °C
= Specific heat of water = 4186 J/(kg °C)
= mass of aluminum = 0.400 kg
= initial temperature of aluminum = 26.0 °C
= Specific heat of aluminum = 900 J/(kg °C)
= mass of copper = 0.100 kg
= initial temperature of copper = 100 °C
= Specific heat of copper = 386 J/(kg °C)
= Final temperature of mixture
Using conservation of heat
( - ) + ( - ) + ( - ) = 0
(0.250) (4186) ( - 20) + (0.400) (900) ( - 26) + (0.100) (386) ( - 100) = 0
= 23.63 °C
Answer:

Heat lost by hot metal bolt
Heat gained by water
Answer:4. Two charged objects have a repulsive force of 0.080 N. If the distance separating the objects is tripled, then what is the new force? Explanation: The electrostatic force is inversely related to the square of the separation distance.
Explanation:
Answer:
Forces that the rider applies to the pedals, saddle and handlebars during speeding, hill climbing and starting are estimated from cine film records using elementary mechanics. The results are compared with force measurements obtained from an instrumented pedal. Pedal forces of up to three times bodyweight were recorded during starting. Handlebar loads were always significantly large.
