Answer:
Option A
D = m/v
Explanation:
Density is defined as mass per unit volume of an object. Therefore, D=m/v where m is the mass of the object and v is the volume
Therefore, option A is the right option
Answer:
(a). Index of refraction are 
= 1.344 & 
= 1.406
(b). The velocity of red light in the glass 
2.23 ×
The velocity of violet light in the glass 
2.13 ×
Explanation:
We know that
Law of reflection is
Here
= angle of incidence
= angle of refraction
(a). For red light
1 × 
= × 
= 1.344
For violet light
1 × = × 
= 1.406
(b). Index of refraction is given by
= 1.344
2.23 ×
This is the velocity of red light in the glass.
The velocity of violet light in the glass is given by
2.13 ×
This is the velocity of violet light in the glass.
The answer is:
Heat transfer.In order to heat up water there has to be a way that the heat puts energy into the water,which make is rise in temperature.
I hope this helps :D
Newtons second law of motion: "T<span>he acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object."
kinetic energy is energy that an object posses while in motion and to get that it must have potential energy.</span>
