Mg(c) + 237shi (4z) ¥at h2)
Respuesta:
60°
Explicación:
Paso 1: Información dada
- Distancia recorrida (d): 2000 cm
- Fuerza aplicada (F): 80 N
- Trabajo realizado (W): 800 J
Paso 2: Convertir "d" a metros
Usaremos el factor de conversión 1 m = 100 cm.
2000 cm × 1 m/100 cm = 20 m
Paso 3: Calcular el ángulo entre la cuerda y el suelo (θ)
W = F × d × cosθ
800 J = 80 N × 20 m × cosθ
θ = 60°
Answer:
Answer in explanation
Explanation:
Gases are expected to behave as ideal gases at particular temperature and pressure know as the S.T.P.
At a temperature of 273k and a pressure of 1atm, it is expected that a mole of a gas will occupy a volume of 22.4L. Now, a particular student measured the pressure of a gas at 425K, it is expected that the pressure is different from the one that is supposed to be observed at STP and thus , the measures quite differently
When a change in PH = 10^-ΔPH
so the change = 10^-3.2
change depends on two factor 0.00063 (10^-3.2)and factor 1585 (10^3.2)depending on the way which the change goes.if PH change from PH=0 to PH= 3.2 so the change is decreasing from concentration from 1 mol to 0.00063 and if PH change from PH = 3.2 to PH=0 so the change is increasing by a factor of 1585.
The answer is B. In order to test something out you need to be able to solve it.
