For a simple pendulum, the mathematical equation that describes the period (T) is T=√(l/g) where l is the length of the string and g is the acceleration due to gravity (9.81 metres per second). Therefore it can be seen that both gravity and the length of the string within a pendulum effects its period.
Answer:
2.81 kW
Explanation:
Initial power output, P = 20.0 kW
Initial amplitude, A = 1.20 m
Final Amplitude, A = 0.450 m
Power is proportional to extracted energy which is proportional to the intensity of the wave and intensity of the wave is directly proportional to the square of the amplitude.
P ∝ E ∝ I ∝ A²
Substitute the values to find the value of power produced:
There is a force of 2 Newtons to the RIGHT, and a force of 4 Newtons to the LEFT. The Net Force would be 4 Newtons RIGHT minus 2 Newtons LEFT =
B. 2 Newtons to the left
Explanation:
In other words, accuracy describes the difference between the measurement and the part's actual value, while precision describes the variation you see when you measure the same part repeatedly with the same device.
