Newton’s Third Law of Motion states that for every action there is an equal and opposite reaction. So look for a scenario in which something had force applied upon it and the reaction is a force in the opposite direction of the same size.
Answer:
![g=25.92\ m/s^2](https://tex.z-dn.net/?f=g%3D25.92%5C%20m%2Fs%5E2)
Explanation:
Given that,
The mass of the Jupiter,![M=1.9\times 10^{27}\ kg](https://tex.z-dn.net/?f=M%3D1.9%5Ctimes%2010%5E%7B27%7D%5C%20kg)
The radius of Jupiter,![r=69,911\ km=69911\times 10^3 km](https://tex.z-dn.net/?f=r%3D69%2C911%5C%20km%3D69911%5Ctimes%2010%5E3%20km)
We need to find the acceleration due to gravity on Jupiter. The formula is
![g=G\dfrac{M}{r^2}](https://tex.z-dn.net/?f=g%3DG%5Cdfrac%7BM%7D%7Br%5E2%7D)
Put all the values,
![g=6.67\times 10^{-11}\times \dfrac{1.9\times 10^{27}}{(69911\times 10^3)^2}\\\\g=25.92\ m/s^2](https://tex.z-dn.net/?f=g%3D6.67%5Ctimes%2010%5E%7B-11%7D%5Ctimes%20%5Cdfrac%7B1.9%5Ctimes%2010%5E%7B27%7D%7D%7B%2869911%5Ctimes%2010%5E3%29%5E2%7D%5C%5C%5C%5Cg%3D25.92%5C%20m%2Fs%5E2)
So, the value of acceleration due to gravity on the Jupiter is

Answer:
<em>It will cost $20.81</em>
Explanation:
<u>Cost of Electricity</u>
The rate of the cost of electricity is usually expressed in $/KWH because the consumption of electricity is measured in Kilowatts-hour.
If a 25W porch light is on day and night for a full year, the electricity consumption is:
25W*24 H/Day*365 Day/year* 1 year=219,000 WH
converting to KWH: 219,000 WH = 219,000 /1000 KWH = 219 KWH
The rate is $0.095/KWH, thus:
The cost of electricity is 219 KWH*$0.095/KWH= $20.81
It will cost $20.81
