Answer: C
Explanation: Side post terminals need to be removed to inspect them for corrosion.
Over tightening the terminal bolt can damage side post terminals.
The battery terminals and cable ends can corrode especially when the battery or car is not used for a long period of time. Corrosion limits a battery's lifespan and so should be prevented. To inspect the areas where corrosion occur on a side-post battery, you need to remove the terminals.
Also, it is true that over tightening the terminal bolt can damage the side post terminals. The covering on the battery can become twisted, and make the seals on the terminals leak.
Answer:
q_enclosed = 759.57 nC
Explanation:
A cylindrical shell of radius 7.00 cm and length 2.48 m has its charge uniformly distributed on its curved surface. The magnitude of the electric field at a point 15.3 cm radially outward from its axis (measured from the midpoint of the shell) is 36.0 kN/C.
Find the value of the net charge on the shell.
Given that Length L of the cylinder shell is 248 cm and the diameter d is 7.0 cm. We can approximate L >> d. This approximation concludes that the cylindrical shell is infinitely long, when we are examining the Electric fiel strength E from the ends of the shell.
Hence,
E = q_enclosed / 2*pi*ε_o *r*l
Where r = d / 2, then
q_enclosed = E*(2*π*r*l*ε_o)
q_enclosed = (36000)*(2*π*8.85*10^-12 *0.153*2.48)
q_enclosed = 759.57 nC

Explanation:
Answer:
I) Heat capacity of ice (Sensible, ice), II) Enthalpy of fusion of water (Latent, fusion) and III) Heat capacity of water (Sensible, water).
Explanation:
At standard pressure, water has a fusion point and boiling point of 273.15 K and 373.15 K, respectively. Then, the total change in enthalpy is the sum of two sensible indicators and one latent indicator. That is:
![\Delta H_{total} = \Delta H_{sensible, ice} + \Delta H_{latent, fusion} + \Delta H_{sensible, water}](https://tex.z-dn.net/?f=%5CDelta%20H_%7Btotal%7D%20%3D%20%5CDelta%20H_%7Bsensible%2C%20ice%7D%20%2B%20%5CDelta%20H_%7Blatent%2C%20fusion%7D%20%2B%20%5CDelta%20H_%7Bsensible%2C%20water%7D)
The needed physical constants are: Heat capacity of ice (Sensible, ice), Enthalpy of fusion of water (Latent, fusion) and Heat capacity of water (Sensible, water).
Answer:
330 m/s approx
Explanation:
The RMS speed of a gas is proportional to square root of its absolute temperature is
V ( RMS ) ∝ √T
![\frac{V_1}{V_2} =\sqrt{\frac{T_1}{T_2} }](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BV_2%7D%20%3D%5Csqrt%7B%5Cfrac%7BT_1%7D%7BT_2%7D%20%7D)
Here V₁ = 200 , T₁ = 23 +273 = 300K , T₂ = 227 +273 = 500 K
Putting the values
200 / V₂ = ![\sqrt{\frac{300}{500} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B300%7D%7B500%7D%20%7D)
V₂ = 330 m/s approx
