Answer:
Cp = 0.142 [cal/g*°C].
Explanation:
In order to solve this problem, we must use the following equation of thermal energy.
where:
Q = heat energy = 60 [cal]
Cp = specific heat [cal/g*°C]
T_final = final temperature = 10[°C]
T_initial = initial temperature =40[°C]
m = mass of the substance = 14 [g]
Now replacing:
Answer: time is the same
Explanation: the distance(H) is the same in each case .
we drop the balls , no drag force using basic kimnematics
y =gt*t/2 , yo=0 , vo=0 , y=H , so : t= sqrt(2H/g)
comment: if distance H starts to grow....we could begin to note a difference because of gravity g is smaller as we go up
When all the lights are in series, and any one of them burns out
or is pulled out, or the wire between the lights is cut anywhere,
ALL the lights go out.
If all the lights were in parallel, then they're totally unaware of each
