Answer:
ω= 2.095rad/sec
Explanation:
angular frequency(ω)=2πf
F is the frequency
Frequency of an oscillation is the number of cycles completed per second. One oscillation represents 1cycle. Thus for 13 oscillations, the glider completes 13 cycles.
F= 13/39 =Hz
angular frequency(ω)=2πf
angular frequency(ω)=2π *
= 2**rad/sec
ω= 2.095rad/sec
Answer:
a)
1.73 m/s
b)
6.43 x 10⁻⁴ m
Explanation:
m = mass of the flea = 1.8 x 10⁻⁴ kg
v₀ = initial speed of the flea = 0 m/s
v = final speed of the flea
W = work done by the force on the flea = 2.7 x 10⁻⁴ J
Using work-change in kinetic energy, Work done is given as
W = (0.5) m (v² - v₀²)
Inserting the values
2.7 x 10⁻⁴ = (0.5) (1.8 x 10⁻⁴) (v² - 0²)
v = 1.73 m/s
b)
d = distance moved by the flea while pushing off
F = Upward force applied on the flea by ground = 0.42 N
Work done is also given as
W = F d
2.7 x 10⁻⁴ = (0.42) d
d = 6.43 x 10⁻⁴ m
A periodic wave has a fixed pattern that is repeated. One completion of the wave pattern is called as cycle of the wave.
<u>Explanation:
</u>
Periodic waves are those which repeat the same kind of behaviour or pattern after a particular interval of time. So, completion of behaviour or pattern for a given time interval is termed as the cycle of wave.
Generally, one complete wave pattern makes a time interval of 2π. So each cycle will take nearly 2π time to form. The repetition of cycle in a time interval will help us to derive the frequency of the system.
