Elevation would be showing you what height you are at, energy would be like what force your putting into the object.

<h2>
Option A is the correct answer.</h2>
Explanation:
A 10-ω resistor and a 30-ω resistor are connected in series across a 100-V battery
Total resistance = 10 + 30 = 40 ω
We have
Voltage = Current x resistance
100 = I x 40
I = 2.5 A
In series current in all the resistors are same, that is 2.5 A
Voltage in 10ω resistor, V = I x 10 = 2.5 x 10 = 25 V
In parallel connection potential in all the resistors are same.
Voltage in 10ω resistor, V = 100 V
The ratio of the potential difference across the 10-ω resistor in the series combination to that of the 10-ω resistance connected in parallel = 25/100 = 1/4
Option A is the correct answer.
Answer:
Between -35 degrees C and 355 degrees C
Explanation:
At any temperature between, but not including the freezing and boiling points, the substance would be in its liquid state.
Specific heat formula is Q=M*C*ΔT
Q is amount of energy (4786 J)
M is mass (89.0 g)
C is specific heat (unknown, answer will be in J/gºC)
ΔT is the change in temp (89.5-23.0=66.5ºC)
Let's plug it in.
4786=89.0(C)(66.5)
4786=5918.5(C)
/5918.5
C=.8086508406 J/gºC
with sig figs...
C=.809 J/gºC
