Answer:
No, you can't keep on dividing the charge forever.
Explanation:
No, you can't keep on dividing the charge in that manner forever because the total charge of the stick is an integer multiples of individual units known as an elementary charge, <em>which is the electron (e) charge (e = 1.602x10⁻¹⁹C)</em>.
Therefore the limit of the division of the original charge will be the electron charge since it is the smallest charge that can exist freely.

Answer:
8 time increase in K.E.
Explanation:
Consider Mass of truck = m kg and speed = v m/s then
K.E. = 1/2 ×mv²
If mass and speed both are doubled i.e let m₀ = 2m and v₀ = 2v then
(K.E.)₀ = 1/2 ×2m(2v)²
(K.E.)₀ = 8 (1/2 × mv²) = 8 × K.E.
Answer:
46.9 C
Explanation:
The heat released by the gold bar is equal to the heat absorbed by the water:
where:
is the mass of the gold bar
is the specific heat of gold
is the initial temperature of the gold bar
is the mass of the water
is the specific heat of water
is the initial temperature of the water
is the final temperature of both gold and water at equilibrium
We can re-arrange the formula and solve for T_f, so we find:
