Answer:

Speed, mass and acceleration

Explanation:

A scalar quantity is a quantity that has only magnitude but no direction while a vector quantity has both magnitude and direction.

According to the question, the row that has two scalars and one vector is speed, mass and acceleration.

The two scalars in this row are speed and mass while the vector quantity there is the acceleration.

Acceleration has direction since it possess direction. A body accelerating will do so in a particular direction. Speed and mass doesn't possess any direction. Mass only specify the magnitude of the body but no clue as to which direction is the body moving towards.

Speed also only specify the

total distance covered with respect to time but not the direction of the direction.

If the ultraviolet photon has a wavelength of 249 nm and one of the photons emitted by the fluorescent material has a wavelength
melamori03 [73]

Answer:

601 nm

Explanation:

Energy of photon having wavelength of λ nm

= \frac{1244}{\lambda}eV

Energy of 249 nm photon

=\frac{1244}{249}

=4.996 eV

Similarly energy of 425nm photon

=\frac{1244}{425}

=2.927 eV

Difference = 2.069 eV.

This energy will give rise to another photon whose wavelength will be

λ = \frac{1244}{2.069}

= 601 nm.
