Answer:
Explanation:
Given :
Force with which dog pulls the pillow = 5 N
Angle of force to the horizontal = 37°
To find the 
and 
components of force.
Solution:
For a force 
making an angle 
with the horizontal, the
1) component or the horizontal component is given by:
2) component or the vertical component is given by:
Plugging the know values to find and components of force applied by the dog on pillow
1) 
∴ (Answer)
2) 
∴ (Answer)
Answer:
The answer is explained below.
Explanation:
The energy emitted during the de-excitation of an electron from a higher energy level to a lower energy level is directly proportional to the frequency of the emitted light.
Here, the total sum of the energies of 2 frequencies of light emitted in different stages is equal to the energy of a single frequency of light during the de-excitation of fourth level to ground level directly.
Hence the total sum of of the frequencies of 2 lights emitted in different stages is equal to the frequency of single frequency of light emitted during the de-excitation from fourth level to ground level directly.
The some of the energies of 2 frequencies emitted by one electron is equal to the energy of a single frequency when electron jumps directly.
6x2=12m
6x18=108
12m+108
Simplified: m+9 bc 12/12 and 108/12
