A resistor can get hot when a current flows through it, and the unit of resistance is the Ohm.

What are some properties of electrical current?

When an electric current flows through a resistor, it can generate heat. This phenomenon occurs due to the resistance offered by the resistor to the flow of electrons. When the electrons pass through the resistor, they collide with atoms and molecules, transferring their kinetic energy and resulting in an increase in temperature. This heating effect is commonly observed in various electronic devices, such as heaters or incandescent light bulbs.

Additionally, the unit of resistance in the International System of Units (SI) is the Ohm, represented by the symbol Ω. Resistance is a fundamental property of electrical components, describing their ability to impede the flow of electric current. It is calculated by dividing the voltage across a component by the current passing through it, according to Ohm's law.

Answer:

$108.90

Explanation:

step 1. multiply kw by rate of change ( 1.1kw x .11 = .121)

step 2. multiply the product above by the time use which is 30 mins in this case so .121 x 30 = 3.63

step 3. last step is to multiply the product you just got by the time per month soooo 3.63 times 30 days = 108.90 :)

The power charge of the dryer for a month for a period of 30 minutes every day will be 108.9 watts.

Electric power is the rate at which the electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one watt is equal to one joule per second.

The amount of power rate for one minute = 1.1 × 11/100 = 1.1 × 0.11 = 0.121 watts

The amount of power rate for 30 minutes = 0.121 × 30 = 3.63 watts

The power rate for 30 days = 3.63 × 30 = 108.9 watts

Therefore, the power charge for the month is 108.9 watts.

The centripetal acceleration of the child at the low point is approximately 3.67 m/s^2.

The centripetal acceleration of the child at the low point can be calculated using the formula:

Centripetal acceleration (a) = (v^2) / r

Given:

The speed of the child (v) = 3.80 m/s

The radius of the circular path (r) = unknown

To find the radius, we need to consider the distance traveled by the child from the top to the bottom of the incline, which is 7.80 m.

Since the child is at the low point, the radius of the circular path is equal to half of the distance traveled, i.e., r = 7.80 m / 2 = 3.90 m.

Now we can substitute the values into the formula:

a = (3.80^2) / 3.90

Calculating the value:

a ≈ 3.67 m/s^2

Therefore, the centripetal acceleration of the child at the low point is approximately 3.67 m/s^2.

Rate of administration

The rate of administration for the IV solution is approximately 2.778 mL/min.

To calculate the rate of administration in mL/min, we need to convert the total volume of the IV solution (1,000 mL) and the time it takes to administer it (6 hours) into the same unit of time (minutes).

1 hour = 60 minutes

Total volume of IV solution = 1,000 mL

Time for administration = 6 hours = 6 hours × 60 minutes/hour = 360 minutes

Now, we can calculate the rate of administration in mL/min:

Rate = Total volume / Time for administration

Rate = 1,000 mL / 360 minutes

Rate ≈ 2.778 mL/min

Hence, The rate of administration for the IV solution is approximately 2.778 mL/min.

To raise the automobile with a hydraulic lift, a force of approximately 19,000 N must be applied to the piston.

In a hydraulic lift, the principle of Pascal's law is applied, which states that pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and the walls of its container. By utilizing this principle, a smaller force applied to a smaller piston can generate a larger force on a larger piston.

In this scenario, the force needed to lift the automobile can be calculated using the formula:

\(\frac{F_{1}}{A_{1}} =\frac{F_{2}}{A_{2}}\)

where \(F_{1}\) is the force applied to the piston, \(A_{1}\) is the area of the piston, \(F_{2}\) is the force generated on the larger piston (required to lift the automobile), and \(A_{2}\) is the area of the larger piston.

Given the radius of the shaft (small piston) as 0.08 m and the radius of the piston as 0.01 m, we can calculate the forces applied and generated as follows:

\(A_{1} = \pi (0.08)^2\\A_{2}= \pi (0.01)^2\)

\(\frac{F_{1}}{A_{1}} =\frac{F_{2}}{A_{2}}\)

Simplifying the equation and substituting the values, we can solve for \(F_{2}\):

\(F_{2}=\frac{F_{1}A_{2}}{A_{1}}\)

Plugging in the values, we find:

\(F_{2}=\frac{F_{1} \pi (0.01)^2 }{ \pi (0.08)^2} \\F_{2}= \frac{F_{1}\times 0.0001}{0.0064} \\F_{2}= 0.015625 \times F_{1}\)

Given that the mass of the automobile is 1520 kg and the acceleration due to gravity is \(9.8 \hspace m/s^{2}\), we can equate \(F_{2}\) to the weight of the automobile:

\(F_{2}= mg\\0.015625\times F_{1}= 1520\times 9.8\)

Solving for \(F_{1}\), we find:

\(F_{1}\approx \frac{1520\times 9.8}{0.015624} \\F_{1} \approx 19072 \hspace N\)

Therefore, a force of approximately 19,000 N must be applied to the piston in order to raise the automobile using the hydraulic lift.

Given that a 12 V battery is connected to four resistors. We need to calculate the current in the 8.0 Ω resistor.

To find the current flowing through the resistor we need to use Ohm's law.

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

The formula is given as,I = V/R where,I is the current V is the voltage R is the resistance

Therefore, the current through the 8.0 Ω resistor is given by: I = V/R = 12 V / 8.0 ΩI = 1.5 A

So, The current in the 8.0 Ω resistor is 1.5 A.

 The average kinetic energy of CO2 molecules with a root-mean-square speed of 629 m/s is 49.4 kJ/mol.

The   thermodynamics root-mean-square (rms) speed of gas molecules is a measure of their average speed and is related to their kinetic energy. The kinetic energy of a gas molecule is proportional to the square of its speed.

Therefore, the rms speed can be used to calculate the average kinetic energy of the gas molecules. In this case, we are given the rms speed of CO2 molecules as 629 m/s. Using this value, we can calculate the average kinetic energy of CO2 molecules using the formula:

average kinetic energy = 1/2 * m * (rms speed)^2

where m is the molar mass of CO2, which is 44.01 g/mol. Converting this to kg/mol and substituting the values, we get:

average kinetic energy = 1/2 * (0.04401 kg/mol) * (629 m/s)^2 = 49.4 kJ/mol

Radio waves traveling through the ionosphere at high latitudes experience quick and unpredictable oscillations, which is known as high-latitude scintillation.

The auroral border, or area of the ionosphere where the aurora borealis (northern lights) appear, is typically connected with scintillation. However, high-latitude scintillation can occasionally be seen equatorward of the auroral boundary depending on the circumstances. The cause of this phenomenon is the presence of ionospheric irregularities that go beyond the auroral oval, such as irregularities in plasma density brought on by equatorial spread F (ESF). ESF can produce significant ionosphere-wide anomalies that lead to scintillation at lower latitudes. This may occur when the sun is active more intensely or when particular ionospheric circumstances favor the production of these anomalies.
