Answer: +/- 71,65 Calorías
Explanation: Se deduce que la fuerza aplica para aumentar o disminuir la energía del generador.
+/- x Calorías
X = Equivalente de 300 Joules en calorías
Para poder pasar Joules a calorías.
Hacemos una regla de 3 simple
1 Calorías = 4,18 Julios
0,2392 calorías = 1 Julio
( 1 / 4,18 = 0,2392 calorías)
300 Julios = 71,65 calorías
(0,2392 calorías x 300 julios = +/- 71,65 calorías)
The time it takes "to complete one cycle" is a perfect definition for <em>period</em>.
So the <em>2 sec</em> that you measured is the swing's period.
Frequency is just 1/period (the 'reciprocal' of the period).
For this swing, the frequency is 1/(2sec) = 0.5 per second = <em>0.5 Hz</em>.
( "Hertz" means "per second")
Answer:
The percentage change in frequency is 10%.
Explanation:
Given that,
Amplitude decreases by 1/10 per second.
Resonance = 10 Hz
We need to calculate the change in frequency
Using formula of change in frequency

Put the value into the formula


We need to calculate the resonant frequency
Using formula of resonant frequency

Put the value into the formula


We need to calculate the percentage change in frequency
Using formula of percentage change in frequency


Hence, The percentage change in frequency is 10%.
