Answer:
wavelength is 20.71 cm
Explanation:
given data
wave = 43.0 vibrations
time = 29 s
wave travels = 430 cm
time t2 = 14 s
to find out
wavelength
solution
we know here wavelength formula that is
wavelength = velocity / frequency .........................1
here frequency = 43 / 29 = 1.4827 Hz
and velocity = 430 / 14 = 30.71 cm/s
so here from equation 1 put all value
wavelength = velocity / frequency
wavelength = 30.71 / 1.4827
wavelength = 20.71 cm
so wavelength is 20.71 cm
Answer:
516526.863 m
Explanation:
From the question given above, the following data were obtained:
Acceleration due to gravity (g) = 2.24 m/s²
Mass (M) = 8.96×10²¹ Kg
Gravitational constant (G) = 6.67×10¯¹¹Nm²/Kg²
Radius (r) =?
The radius of the planet can be obtained as follow:
g = GM/r²
2.24 = 6.67×10¯¹¹ × 8.96×10²¹ / r²
2.24 = 5.97632×10¹¹ / r²
Cross multiply
2.24 × r² = 5.97632×10¹¹
Divide both side by 2.24
r² = 5.97632×10¹¹ / 2.24
r² = 2.668×10¹¹
Take the square root of both side
r = √2.668×10¹¹
r = 516526.863 m
Thus, the radius of the planet is 516526.863 m
