D) 8.0 s.
Explanation:
(The following exercise is written in Spanish. Hence, explanations will be held in such language.)
La energía requerida para elevar el ascensor es el cambio en la energía potencial gravitacional, cuya magnitud es:
Ahora, la potencia media es el resultado anterior dividido por el tiempo. Se despeja el tiempo de la ecuación:
La opción más aproximada es D.
I think it’s A because it makes the most sense
The independent variable here is the use of diet pills; it was manipulated with the hope of different results
Answer:
the first overtone is 200 Hz
Explanation:
The computation of the first overtone would be given below:
The following formula should be applied
n_1 = n_3 ÷ 3
= 300 ÷ 3
= 100 Hz
Now n_2 is
= 2 × 100
= 200 Hz.
Hence, the first overtone is 200 Hz
we simply applied the above formula and the same would be relevant
