Answer:
No. Neither the USGS nor any other scientists have ever predicted a major earthquake. We do not know how, and we do not expect to know how any time in the foreseeable future. USGS scientists can only calculate the probability that a significant earthquake will occur in a specific area within a certain number of years.
Answer:
Explanation:
a ) For the ray going into syrup , angle of incidence ( i ) is 29.4 and angle of refraction ( r ) is 18.84
Refractive index of syrup = Sin i / Sin r
= Sin 29.4 / Sin 18.84
= 1.51 .
b ) The wavelength of a light is reduced in a medium by the factor of refractive index so
wavelength in the medium
= Wavelength in air / refractive index of the solution
= 632.8 / 1.51
= 419.07 nm .
The frequency remains unchanged . The frequency in the medium will be same as that in air or vacuum.
Frequency in air = Velocity of light in air / wavelength in light
= 3 x 10⁸ / 632.8 x 10⁻⁹
= 4.74 x 10¹⁴ Hz.
Frequency in the medium is same as that in air.
Velocity in the medium
V = velocity in air / refractive index
= 3 x 10⁸ / 1.51
= 1.98 x 10⁸ m /s

Before coming into conclusion first we have to understand both scalar and vector .
A scalar quantity is a physical quantity which has only magnitude for it's complete specification.
A vector quantity is that physical quantity which not only requires magnitude but also possesses direction for it's complete specification.
So the most important factor that differentiate vector from scalar is the direction.
As per the question the student is doing an experiment where he is recording the data obtained during the process.
In order to arrange them in data table, he should ask about the direction of the quantity under consideration.
Hence the correct option is the third option(C)i.e does the measurement include direction?
