I would say false because the volume of gas depends on several things the amount of matter in the volume , the pressure and the temperature. So the answer would be false in my opinion. Because mass is not the only factor
Answer:
R= 5.4 ohms
Explanation:
Given that
V= 9 V
Power ,P= 15 W
Lets take resistor resistance = R
We know that Power given as
V=Voltage
P=Power
R=Resistance
Now by putting the all the values in the above equation
R= 5.4 ohms
Therefore the resistance of the resister will be 5.4 ohms.
Answer:
v = 3.24 m/s
Explanation:
Since we don't have time, we can use the formula;
(Final distance - initial distance)/time = (initial velocity + final velocity)/2
Thus;
(x_f - x_i)/t = ½(v_xi + v_xf)
We are given;
x_i = 0 m
x_f = 5 m
v_xi = 0 m/s
v_xf = 5 m/s
Thus, plugging in the relevant values;
(5 - 0)/t = (0 + 5)/2
5/t = 5/2
t = 2 s
Using Newton's first law of motion, we can find the acceleration.
v = u + at
Applying to this question;
5 = 0 + a(2)
5 = 2a
a = 5/2
a = 2.5 m/s²
To get the speed, in m/s, of the block when it had traveled only 2.1 m from the top, we will use the formula;
v² = u² + 2as
v² = 0² + 2(2.5 × 2.1)
v² = 10.5
v = √10.5
v = 3.24 m/s

Answer:
La media es la medida de tendencia central más utilizada y, en general, se considera la mejor medida de la misma. Sin embargo, hay algunas situaciones en las que se prefiere la mediana o la moda.
La mediana es la medida preferida de tendencia central cuando:
Hay algunas puntuaciones extremas en la distribución de los datos.
