5.4 x 1014Hz
wavelength x frequency = the speed of light
We know, For a substance they both are equal in magnitude, i.e.,
Specific Gravity = Density
Specific Gravity = 19.3 [ As Density = 19.3 ]
In short, option C would be your correct Answer!
Hope this helps!
The distance that is traveled by the astronaut given that the motion is free-fall can be calculated through the equation,
d = Vot + 0.5at²
where d is the distance, Vo is the initial velocity, t is the time, and a is the acceleration. Substituting the known,
6 = (0 m/s)(2.7 s) + 0.5(a)(2.7 s)²
Determining the value of a,
a = 1.646 m/s²
ANSWER: 1.646 m/s²
