Answer:
Explanation:
Potential energy of a pair of charges
= k q₁q₂ /r₁₂
At r₁₂ = .125 m
= - 9 x 10⁹ x 2.4 x 4.3 x 10⁻¹² / .125
= - 743 x 10⁻³J
At r₁₂ = √2 x .275 m
- 9 x 10⁹ x 2.4 x 4.3 x 10⁻¹² / √2 x .275
= - 238.85 x 10⁻³J
= 239 x 10⁻³ J
Change = - 238.85 x 10⁻³ +743 x 10⁻³
= 504.15 x 10⁻³ J
B )
Work done by electric force will be same but in negative sign
= - 504.15 x 10⁻³ J
= - 504 x 10⁻³ J
Answer:
You can get w =Fxd 20Nx5m w=100N energy= w÷t 100N÷4s E=25J 3 you can apply 3J in one second
The act of Adjusting your speed to address one hazard at a time when faced with multiple risks is: (c) Separating
Meaning of separating Hazards
A hazard can be defined primarily as an occurrence that can lead to damage of properties and destruction of live.
separating Hazards can be defined as an act of adjusting one's speed in other to attend to one hazard before another.
In conclusion, The act of Adjusting your speed to address one hazard at a time when faced with multiple risks is: (c) Separating

Answer:
your body is exerting a force on the chair and nothing is happening
Explanation:
Wavelength = (wave speed) / (frequency)
= (1,450 m/s) / (230 / sec)
= 6.30 meters (rounded)
Hope this helped friend! :)
