Explanation:
Distance covered = Total distance travelled by the car
Since the car travels to school and back to home again,
Total diatance covered = 8 + 8 = 16km
Displacement = Shortest distance between start point and destination.
Since, the car returns back to home from school,
the start and destination point are same.
So Displacement = 0
Answer: Option (B) is the correct answer.
Explanation:
In a solid, molecules are held together by strong intermolecular forces of attraction. As a result, they are unable to move from their initial place but they can vibrate at their mean position.
Hence, in solid substances the molecules have low kinetic energy.
Whereas in liquids, the molecules are held by less strong intermolecular forces of attraction as compared to solids. Due to which they are able to slide past each other. Hence, they have medium kinetic energy.
In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.
Hence, gases are able to expand more rapidly as compared to liquids.
Thus, we can conclude that out of the given options solid = low; liquid = medium; gas = high, combination of the state of matter and the corresponding dryer speed is correct.
Answer:
<em>709.5 cal</em>
<em></em>
Explanation:
masa m de la barra de aluminio = 100 g
temperatura ambiente = 27 ° C
<em>Asumiremos que la barra de aluminio está en equilibrio térmico con el ambiente.
</em>
Esto significa que la temperatura inicial de la barra es de 27 ° C
temperatura final a la que la barra debe calentarse = 60 ° C
el aumento de temperatura ΔT será
ΔT = 60 ° C - 27 ° C = 33 ° C
capacidad calorífica específica c del aluminio = 0.215 cal/g°C
Calor C requerido = mcΔT
<em>C = 100 x 0.215 x 33 = 709.5 cal</em>
