Answer:
distance = 6 m
Explanation:
- Distance is a scalar quantity (so, only magnitude, no direction), and it is calculated as the scalar sum of all the distances travelled by an object during its motion, regardless of the direction. So, in this problem, the distance covered by the pinecone is
d = 4 m + 2 m = 6 m
- Displacement is a vector quantity (magnitude+direction), and its magnitude is calculate as the distance in a straight line between the final position and the initial position of the object. In this case, the final position is 2 m west and the initial position is 0 m, so the displacement of the pinecone is
d = 2 m west - 0 m = 2 m west
So, a scalar quantity from this scenario is
distance = 6 m
Answer:

Explanation:
In microwave, there are waves called "microwaves" as per the name. So, The heating of food is done with the help of waves. Radiation is "the transfer of heat through waves". That is why the process of heating food in a microwave is "Radiation".

Answer: Option (A) is the correct answer.
Explanation:
One of the equation for diffraction grating is as follows.
or,
And, for greater value of
the spacing gets wider.
Hence, in order to increase
, the wavelength would have to increase or spacing has to decrease.
Thus, we can conclude that increase the wavelength of the light changes would increase the separation between the bright fringes in the diffraction pattern formed by diffraction grating.
