Answer:
Specific heat: = energy required to change a unit mass of a material by 1°C. Units: energy per unit mass per degree.
Latent heat = energy required to change the state (gas, liquid, solid) of a unit mass of material. Units: energy per unit mass.
Explanation:
Explanation:
a triple beam balance can measure the mass of one slice of bread
55 Kg has a weight of 55x9.8= 539 N
That is equal to the Normal force.
The static friction = 0.19 x 539 = 102.4 N
The car's average speed during that time is (23.7/2) = 11.85 m/s .
Distance = (11.85 m/s) x (6.5 sec) = 77.025 meters .
