Explanation:
= Power of the bulb = 100 W
= distance from the bulb = 2.5 m
= Intensity of light at the location
Intensity of the light at the location is given as
![I = \frac{P}{4\pi r^{2}}](https://tex.z-dn.net/?f=I%20%3D%20%5Cfrac%7BP%7D%7B4%5Cpi%20r%5E%7B2%7D%7D)
![I = \frac{100}{4(3.14) (2.5)^{2}}](https://tex.z-dn.net/?f=I%20%3D%20%5Cfrac%7B100%7D%7B4%283.14%29%20%282.5%29%5E%7B2%7D%7D)
= 1.28 W/m²
= maximum magnetic field
Intensity is given as
![I = \frac{B_{o}^{2}c}{2\mu _{o}}](https://tex.z-dn.net/?f=I%20%3D%20%5Cfrac%7BB_%7Bo%7D%5E%7B2%7Dc%7D%7B2%5Cmu%20_%7Bo%7D%7D)
![1.28 = \frac{B_{o}^{2}(3\times 10^{8})}{2(12.56\times 10^{-7})}](https://tex.z-dn.net/?f=1.28%20%3D%20%5Cfrac%7BB_%7Bo%7D%5E%7B2%7D%283%5Ctimes%2010%5E%7B8%7D%29%7D%7B2%2812.56%5Ctimes%2010%5E%7B-7%7D%29%7D)

<u>Given</u><u>:</u>
- An object has a forward force = 100N
- An object has a reverse force = 25N
<u>To</u><u> </u><u>find</u><u> </u><u>out</u><u>:</u>
What is the resultant force?
<u>Solution</u><u>:</u>
Resultant Force = Forward force + Reserve force
= 100 N + ( - 25 N )
= 75 N
The offspring can have some features for the parents relatives and can look nothing like the parents. They can look exactly alike to more of one parent then the other or have features from both parents as well
Hope this helps :3
