Answer:
There are many examples of electrostatic phenomena, from those as simple as the attraction of the plastic wrap to one's hand after it is removed from a package to the apparently spontaneous explosion of grain silos, the damage of electronic components during manufacturing, and photocopier & laser printer operation
Answer:
No it cannot
Explanation:
The mass number of an atom is equal to the sum of the number of neutrons plus the number of protons in that atom. While the atomic number isjust the number of protons in it.
Therefore the number of protons + number of neutrons cannot be smaller than the number of protons.
The heat energy lost or gained by a substance is given by the equation
Q = mCΔT, where
Q is the heat energy gained or lost by a substance,
m is mass (in grams),
C is the specific heat of the substance,
ΔT is the change in temperature (final temperature - initial temperature).
The joules given off by 617 grams of water cooling from 65°C to 28°C, given the specific heat of water as Cw=4.186 J/g*Co, is:
Q = mCwΔT
Q = (617)(4.186)(28 - 65)
Q = -95562.194
Negative means heat is lost, so 96000 J of heat was lost.
