Answer:
a = (v₃₂ - v₂₁) / (t₃₂ -t₂₁)
Explanation:
This is an exercise of average speed, which is defined with the variation of the distance in the unit of time
v = (y₃ - y₂) / (t₃-t₂)
the midpoint of a magnitude is the sum of the magnitude between 2
t_mid = (t₂ + t₃) / 2
the same reasoning is used for the mean acceleration
a = (v_f - v₀) / (t_f - t₀)
in our case
a = (v₃₂ - v₂₁) / (t₃₂ -t₂₁)
Answer:
terminal voltage = 1.34 V
power = 2.68 W
Explanation:
given data
voltage E = 1.54 V
current = 2A
internal resistance = 0.100 ohm
to find out
terminal voltage and electrical power
solution
we know terminal voltage formula is
terminal voltage = E - current × resistance
terminal voltage = 1.54 - ( 2 × 100 )
terminal voltage = 1.34 V
and
power is calculated by ohm law
Power = V × current
power = 1.34 × 2
power = 2.68 W
Answer: 3- Large cells of rising and sinking gasses
Explanation: Hotter gas coming from the radiative zone expands and rises through the convective zone. It can do this because the convective zone is cooler than the radiative zone and therefore less dense. As the gas rises, it cools and begins to sink again. As it falls down to the top of the radiative zone, it heats up and starts to rise. This process repeats, creating convection currents and the visual effect of boiling on the Sun's surface.
In this case W is negative, the heat input is less than in the constant volume case, and CP is less than CV. If the ice melts it is as if it were being compressed because its volume is reduced.

True. Solvents are always materials that contain the solute. Water contains the salt, in this instance.
