A resistor with R1=25.0 ohm is connected to a battery that has internal resistance and electrical energy is dissipated by R1 at

xz_007 [3.2K]

Use the power and R1 to find the voltage of the battery
P = V²/R
V = √(PR) = √(36.0 W)(25.0 ohm) = 30 V

Now find the equivalent resistance of the new configuration
R_equivalent = R1 + R2 = 40 ohm

Now find the power (energy rate)
P = V²R = (30 V)²/(40 ohm) = 22.5 W

In what kind of wave are waves perpendicular to the direction of the wave motion

Wittaler [7]

Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction which the wave moves.

A toy helium balloon is initially at a temperature of T = 24o C. Its initial volume is 0.0042 m3 (It is a 10 cm radius sphere).

Anettt [7]

Answer:

$T_{f} = 335.780\,K\,(62.630\,^{\textdegree}C)$

Explanation:

Let assume that air behaves ideally. The equation of state of ideal gases is:

$P\cdot V = n\cdot R_{u}\cdot T$

Where:

$P$ - Pressure, in kPa.

$V$ - Volume, in m³.

$n$ - Quantity of moles, in kmol.

$R_{u}$ - Ideal gas constant, in $\frac{kPa\cdot m^{3}}{kmol\cdot K}$ .

$T$ - Temperature, in K.

Since there is no changes in pressure or the quantity of moles, the following relationship between initial and final volumes and temperatures is built:

$\frac{V_{o}}{T_{o}} = \frac{V_{f}}{T_{f}}$
