Heya!!
For calculate period, lets applicate formula:
<u>Δ Being Δ</u>
T = Period = ?
f = Frequency = 660 Hz
⇒ Let's replace according the formula:
⇒ Resolving
Result:
The period of that wave is <u>0,0015 seconds.</u>
<u>Δ IMPORTANT Δ</u>
The period is the INVERSE of the frequency. (T = 1 / f).
And the frequency is the inverse of the period (f = 1 / T)
Good Luck!!
Answer:
A heterogeneous mixture is simply any mixture that is not uniform in composition - it's a non-uniform mixture of smaller constituent parts.
Explanation:
Answer:
While the Applied Force (force exerted) is decreasing, the velocity is decreasing
Explanation:
From Newton's second law of motion, which states that the rate of change of linear momentum is directly proportional to the applied force, and takes place in the direction of the applied force.
Momentum (P) = MV
Thus, F ∝ MV/t
where;
F is the applied force
M is the mass of the object
V is the velocity of the object
From the equation above, force is directly proportional to the velocity of the refrigerator (F∝V). That is, as the applied force is decreasing, the velocity is decreasing and vice versa.
Therefore, while the Applied Force (force exerted) is decreasing, the velocity is decreasing.
Answer:
La mayoría de los adultos necesitan entre 7 y 8 horas de sueño de buena calidad en un horario uniforme todas las noches.
Explanation:
Air mass abbreviated Cp has cold temperature and dry moisture.
Explanation:
Air mass abbreviated Cp means regions of continental polar or continental arctic. So mostly in the northern hemisphere where the temperature is very low like in Alaska, the mass of air is termed as Cp. At those low temperature, the temperature is very cold and so the moisture present in the air in those regions will be dry in nature. Mostly, they originate in the northern hemisphere like in canada, Alaska and then they will spread toward the south and east directions.
So they air masses present in those cooler regions are extremely cold and has dry moisture.
