Answer:
Four fundamental forces are gravitational, electromagnetic, strong, and weak.
Explanation:
The gravitational and electromagnetic interactions, which produce significant long-range forces whose effects can be seen directly in everyday life and the strong and weak interactions, which produce forces at minuscule, subatomic distances and govern nuclear interactions.
For balancing the lever, force on both the sides shall be equal. so,
Force on 3 m end = m × a = 3 × 98.1 = 294.3
Now, on 6 m end, it would be: = 294.3/6 = 49.05
After rounding-off to the nearest hundredth value, it would be: 49 N
Finally, Option A would be your correct answer.

The value is 
Explanation:
From the question we are told that
The the peak wavelength is 
Generally according to the Wien's displacement law
Here T is the approximate surface temperature of this star in K so
=> 
Converting to Fahrenheit ,
![T = [400 - 273.15 ] * \frac{9}{5} + 32](https://tex.z-dn.net/?f=T%20%3D%20%5B400%20-%20273.15%20%5D%20%2A%20%5Cfrac%7B9%7D%7B5%7D%20%2B%2032)
