Answer:
Speed of the wave in the string will be 3.2 m/sec
Explanation:
We have given frequency in the string fixed at both ends is 80 Hz
Distance between adjacent antipodes is 20 cm
We know that distance between two adjacent anti nodes is equal to half of the wavelength
So
We have to find the speed of the wave in the string
Speed is equal to
So speed of the wave in the string will be 3.2 m/sec
Answer:
D
Explanation:
Can you please mark brainiest
and I think it's d because you were at the same sowed as the car but as it turn you moved the other way because of the pull of friction and your weight
hope it helps
A set of two forces that are in opposite directions, have equal magnitudes and act on different objects
Answer:
Explanation:
Y = 5 Sin27( .2x-3t)
= 5 Sin(5.4x - 81 t )
Amplitude = 5 m
Angular frequency ω = 81
frequency = ω / 2π
= 81 / (2 x 3.14 )
=12.89
Wave length λ = 2π / k ,
k = 5.4
λ = 2π / 5.4
= 1.163 m
Phase velocity =ω / k
= 81 / 5.4
15 m / s.
The wave is travelling in + ve x - direction.
Answer:
4.91 years
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of star
v = Oribital velocity of star
T = Oribital time period
R = Radius of orbit
Mass of the star is
Orbital period of the faster planet is 4.91 years
