what is the self-inductance in a coil that experiences a 2.30-v induced emf when the current is changing at a rate of 160 a/s?
Answers
The self-inductance in a coil can be calculated using the formula L = V / (dI/dt), where L is the self-inductance in henries, V is the induced emf in volts, and (dI/dt) is the rate of change of current in amperes per second. Plugging in the given values, we get L = 2.30 V / (160 A/s) = 0.0144 H (or 14.4 mH). Therefore, the self-inductance in the coil experiencing a 2.30-v induced emf when the current is changing at a rate of 160 a/s is 14.4 millihenries.
The self-inductance (L) in a coil can be calculated using the formula:
L = induced EMF / rate of change of current
Given the induced EMF is 2.30 V and the rate of change of current is 160 A/s, you can plug these values into the formula:
L = 2.30 V / 160 A/s
L = 0.014375 H
Therefore, the self-inductance of the coil is 0.014375 henrys (H).

Object starts from rest. Dots are placed every second. What is the acceleration of the object?
Answers
The acceleration of the object is 4.48m/s².
From the graph we can see,
There are 5 dots placed over the line, it means that the object has moved for 5 seconds. The distance which the object has covered in 5 seconds is equal to about 56 meters.
As we know, the object is starting from rest, so the initial velocity is 0m/s.
Now, to find the acceleration a of the object, we can use the equations of motion.
So,
Using,
S = ut + 1/2at²
Where,
u is initial velocity,
S is the distance covered,
and t is the time period of motions of the object.
Putting all the values,
56 = 1/2a(5)²
(56 x 2)/25 = a
a = 4.48m/s²
Hence, the acceleration is 4.48m/s².

Answers
Given information: The average method reports the following unit data for the forming department. Units completed in the forming department are transferred to the painting department. Production cost information for the forming department follows.
Direct materials:
Units completed during the period = 45,000 units
Ending work in process inventory = 5,000 units
Direct materials cost = $202,500
Conversion costs:
Units completed during the period = 45,000 units
Ending work in process inventory = 5,000 units
Conversion cost = $189,000
a. Calculation of equivalent units of production for both direct materials and conversion for the forming department:
Equivalent units of production = Units completed during the period + (Ending work in process inventory * Degree of completion)
Direct materials:
Equivalent units of production = 45,000 + (5,000 * 50%) = 47,500 units
Conversion costs:
Equivalent units of production = 45,000 + (5,000 * 60%) = 48,000 units
b. Calculation of the cost per equivalent unit of production for both direct materials and conversion for the forming department:
Cost per equivalent unit of production = Total cost for the period / Equivalent units of production
Direct materials:
Cost per equivalent unit of production = $202,500 / 47,500 units = $4.26 per unit
Conversion costs:
Cost per equivalent unit of production = $189,000 / 48,000 units = $3.94 per unit
c. Calculation of the cost assigned to the forming department's output using the weighted average method:
Total cost = Cost of units transferred out + Cost of ending work in process inventory
Cost of units transferred out = Number of units transferred out * Cost per equivalent unit of production
Cost of ending work in process inventory = Number of units in ending work in process inventory * Cost per equivalent unit of production
Direct materials:
Cost of units transferred out = 40,000 * $4.26 per unit = $170,400
Cost of ending work in process inventory = 5,000 * $4.26 per unit = $21,300
Total cost = $170,400 + $21,300 = $191,700
Conversion costs:
Cost of units transferred out = 40,000 * $3.94 per unit = $157,600
Cost of ending work in process inventory = 5,000 * $3.94 per unit = $19,700
Total cost = $157,600 + $19,700 = $177,300

a disk of mass 3.5 kg and radius 80 cm is rotating at 2.3 rev/s. a small mass of 0.06 kg drops onto the edge of the disk. what is the disk's final rotation rate (in rev/s)?
Answers
The disk's final rotation rate (in rev/s) is 2.55 rev/s.
To calculate this, we must use the angular momentum of the disk. The angular momentum of the disk before the mass dropped onto it is equal to 2.3 rev/s x (3.5 kg x (80 cm)2). After the mass drops onto the disk, the angular momentum will be equal to (3.5 kg x (80 cm)2) x (2.55 rev/s). We can calculate the change in angular momentum by subtracting the two equations. The change in angular momentum is equal to 0.06 kg x (80 cm)2 x (2.55 rev/s - 2.3 rev/s). Thus, the final rotation rate is equal to 2.55 rev/s. This is the new angular momentum divided by the mass of the disk multiplied by the radius of the disk squared.

The linear speed of a rotating wheel of radius 2 feet is 200f(t)/(m)in. What is the angular speed of the wheel in radians per minute? Round your answer to two decimal places. i
Answers
The angular speed of the wheel is **100π** radians per minute.
The linear speed of a rotating wheel is the distance traveled by a point on the circumference of the wheel per unit time. In this case, the linear speed is given as 200f(t)/(m)in, where f(t) represents an arbitrary function of time and m represents an arbitrary unit of measurement.
To find the angular speed of the wheel, we need to convert the linear speed into angular speed. Angular speed is defined as the rate at which an object rotates or travels around a circular path. It is measured in radians per unit time.
To convert the linear speed into angular speed, we need to relate the linear speed to the circumference and radius of the wheel. The circumference of a circle is given by 2π times the radius. In this case, the radius of the wheel is given as 2 feet.
Since the linear speed is the distance traveled per unit time, we can calculate the distance traveled in one minute by multiplying the linear speed by 60. Dividing this distance by the circumference of the wheel gives us the number of revolutions per minute. To convert this into radians per minute, we multiply the number of revolutions by 2π.
In summary, to calculate the angular speed of the wheel, we take the given linear speed and convert it into the number of revolutions per minute. We then multiply this value by 2π to obtain the angular speed in radians per minute.

The position and velocity of the ball change with time as the ball flies through the air. The correct answer is d.
When a ball is thrown, its position and velocity change continuously as it moves through the air. The position of the ball changes as it moves farther away from the point of release, and the velocity of the ball changes as it accelerates due to the force exerted by the thrower's hand and decelerates due to the effect of gravity. However, since the air resistance on the ball is negligible, the acceleration of the ball remains constant throughout its flight. Therefore, only the position and velocity of the ball change with time as it flies through the air, while the acceleration remains constant. Hence option d is correct.

What is Lorentz number? The thermal and electrical
conductivities of Cu at 200C are 390 Wm-1K-1 and 5.87 x107-1m-1
respectively. Calculate Lorentz number.
Answers
The value of the Lorentz Number is L = (390 W/(m·K)) / (5.87 x 10^7 Ω^(-1)·m^(-1) * 473.15 K).
The Lorentz number, denoted by L, is a fundamental constant in physics that relates the thermal and electrical conductivities of a material. It is given by the expression:
L = (π^2 / 3) * (kB^2 / e^2),
where π is pi (approximately 3.14159), kB is the Boltzmann constant (approximately 1.380649 x 10^-23 J/K), and e is the elementary charge (approximately 1.602176634 x 10^-19 C).
To calculate the Lorentz number, we need to know the thermal conductivity (κ) and the electrical conductivity (σ) of the material. In this case, we are given the thermal conductivity (κ) of copper (Cu) at 200°C, which is 390 W/(m·K), and the electrical conductivity (σ) of copper (Cu) at 200°C, which is 5.87 x 10^7 Ω^(-1)·m^(-1).
The Lorentz number can be calculated using the formula:
L = κ / (σ * T),
where T is the temperature in Kelvin. We need to convert 200°C to Kelvin by adding 273.15.
T = 200 + 273.15 = 473.15 K
Substituting the given values into the formula:
\(L = (390 W/(m·K)) / (5.87 x 10^7 Ω^(-1)·m^(-1) * 473.15 K).\)
Calculating this expression will give us the value of the Lorentz number.

Answers
The r1 = 16 ω resistor dissipates 2.44 W of power. The total power is 216 Watts. power is dissipated by the r1 = 16 ω resistor
First of all, we know that the voltage supplied in the circuit is 12 V. Now, use the formula for Ohm's law to determine the current flowing through the circuit. V = IR or, I = V/RSubstituting the values, we get,I = 12/(16+18)I = 12/34I = 0.3529 A
Therefore, the current flowing through both resistors is 0.3529 A.Now that we know the current, we can calculate the power dissipated by each resistor using the formula: P = I²RSubstituting the values for r1 and r2, we get,Power dissipated by r1 resistor = I²R= (0.3529)² × 16= 2.44 WP = 2.44 W (approx)Power dissipated by r2 resistor = I²R= (0.3529)² × 18= 2.75 WP = 2.75 W (approx)
