Answer:
You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. idk if this helps.
Explanation:
Impermeable is a substance that is water proofed e.g glass, aluminium e.t.c <span />
From the definition of entropy, the entropy change of an object is
where
Q is the heat absorbed
T is the absolute temperature
in our problem, we have Q=25.0 J, while the absolute temperature is (converting in Kelvin)
and so the entropy change is
He's accelerating at 3 m/s² . That means his speed is increasing by 3 m/s every second.At the end of 8 seconds, his speed is (8 x 3 m/s) = 24 m/s .He's been moving south for the whole 8 seconds.So at the end of that time, his velocity is 24 m/s south .
Respuesta:
7,6 Ω
Explicación:
Paso 1: Información dada
- Resistencia a 30 °C (R₀): 6 Ω
- Coeficiente de temperatura (α): 0,00392 °C⁻¹
Paso 2: Hallar la resistencia (R) a 100 °C
Podemos ver la relación entre la resistencia de un material y la temperatura usando la siguiente ecuación.
R = R₀ (1 + α × ΔT)
R = 6 Ω (1 + 0,00392 °C⁻¹ × (100 °C - 30 °C)) = 7,6 Ω
