T=2pi square root 1/g solve for g.<br> Explanation would be really helpful.
Natalija [7]

I added individual steps for clarity. Note that g must be positive if the solution is to be real.

T=2\pi \sqrt{\frac{1}{g}}=2\pi g^{-\frac{1}{2}}\\g^{-\frac{1}{2}} = \frac{T}{2\pi}\\(g^{-\frac{1}{2}})^{-2} = (\frac{T}{2\pi})^{-2}\\g = \frac{4\pi^2}{T^2}\,\,\,, g>0}

Let me know if you have any questions.

hodyreva [135]
A).  Convection is heating the soup in the pot.
When you stick the spoon into the hot soup,
conduction heats the spoon all the way up to the end.

b).  Water conducts heat a little bit. 
But convection is much more responsible for the
uniform distribution of temperature in the kiddie pool.

c).  The heat from the metal bench conducts directly
to the buttus epidermis when you sit on it.

Potential energy is the energy an object has because of its __________.
jasenka [17]

Answer:

option D

Explanation:                                    

The correct answer is option D  

Potential energy of an object is because of its location.

 Expression of potential energy      

     P E = m g H                                  

where H is the height of the object.            

           g is acceleration due to gravity, 9.8 m/s²

           m  is the mass of the object.          

Potential energy is directly proportional to the location of the object.    

If the height of the object is more than the potential energy of the object will also increase.
