The current through an inductor of inductance L is given by I(t) = Imax sin(ωt).
(a) Derive an expression for the induced emf in the inductor as a function of time.
(b) At t = 0, is the current through the inductor increasing or decreasing?
(c) At t = 0, is the induced emf opposing or aiding the flow of the charge carriers? (Remember that the direction of a positive induced emf is the same as the current direction and the direction of a negative induced emf is opposite the current direction.)
(d) How are the answers to parts b and c consistent with the behavior of inductors discussed in the text?
Answers
Answer:
(a) \(emf_L=-LI_{max}\omega cos(\omega t)\)
(b) neither increasing or decreasing
(c) opposite to the flow of charge carriers
Explanation:
The current through an inductor of inductance L is given by:
\(I(t)=I_{max}sin(\omega t)\) (1)
(a) The induced emf is given by the following formula
\(emf_L=-L\frac{dI}{dt}\) (2)
You derivative the expression (1) in the expression (2):
\(emf_L=-L\frac{d}{dt}(I_{max}sin(\omega t))\\\\emf_L=-LI_{max}\omega cos(\omega t)\)
(b) At t=0 the current is zero
(c) At t = 0 the emf is:
\(emf_L=-\omega LI_{max}\)
w, L and Imax have positive values, then the emf is negative. Hence, the induced emf is opposite to the flow of the charge carriers.
(d) read the text carefully
At t zero, the current through the inductor neither increasing nor decreasing because current is zero.
The current through an inductor of inductance L can be calculated by
\(\bold {I_t = I_m_a_x sin (\omega t)}\).........1
(a) The induced emf can be calculated by
\(\bold {emf_L = - L \dfrac {dI}{dt}}\)............2
Derivative the equation (1) in the equation (2)
\(\bold {emf _L= -L \dfrac {d (I _m_a_x sin (\omega t)} {dt}}\\\\\bold {emf _L= -L (I _m_a_x \omega cos( \omega t) }\)
(b) At t=0 the current is zero,
(c) At t = 0 the emf is:
\(\bold {emf_L = -\omega LI _m_a_x}\)
Therefore, at t zero, the current through the inductor neither increasing nor decreasing because current is zero.

The momentum of a 2.5 kg hammer with a speed of 6 m/s has a downward momentum moving towards a nail. The hammer hits the nail and bounces off at 2.0 m/s and the nail is in contact with the nail for 0.002 seconds. What is the average force the nail exerts on the hammer? How could you use force vs. time to solve this problem?
Answers
The average force is equal to the area under the curve of force versus time divided by the time of contact between the hammer and the nail.
The equation can be used to determine the average force the nail applies to the hammer.
\(F = \frac{mv}{t}\), where m is the hammer's mass, v is its speed, and t is the time at which it made impact with the nail. The average force in this situation is given by:
\(F = \frac{(2.5 kg)(6 m/s - 2.0 m/s)}{(0.002 s)}\\ F= 4500 N.\)
To solve this problem using force vs. time, you would need to plot a graph of force versus time, with the time of contact between the hammer and the nail representing the x-axis and the force exerted on the hammer by the nail representing the y-axis. The force exerted on the hammer increases from 0 to 4500 N as the hammer moves from rest to its maximum velocity. The average force is equal to the area under the curve of force versus time divided by the time of contact between the hammer and the nail.

An 8.0 Kg mass is placed at = 3 where should a 10 Kg mass be placed along the − so that the center of mass will be located ay = 4.5?
Answers
Answer:
Therefore, the 10 kg mass should be placed at x = 5.7 m along the x-axis to achieve a center of mass located at y = 4.5 m.
Explanation:
To find the position along the x-axis where a 10 kg mass should be placed such that the center of mass is located at y = 4.5, we can use the formula for the center of mass:
x_cm = (m1 * x1 + m2 * x2) / (m1 + m2)
Here, m1 and x1 represent the mass and position of the 8 kg mass, respectively. m2 is the mass of the 10 kg mass, and we need to find x2, its position.
Given:
m1 = 8 kg
x1 = 3 m
x_cm = unknown (to be found)
m2 = 10 kg
y_cm = 4.5 m
Since the center of mass is at y = 4.5, we only need to consider the y-coordinate when calculating the center of mass position along the x-axis.
To solve for x2, we can rearrange the formula as follows:
x2 = (x_cm * (m1 + m2) - m1 * x1) / m2
Substituting the given values:
x2 = (x_cm * (8 kg + 10 kg) - 8 kg * 3 m) / 10 kg
Simplifying:
x2 = (x_cm * 18 kg - 24 kg*m) / 10 kg
Now, we can set the y-coordinate of the center of mass equal to 4.5 m and solve for x_cm:
4.5 m = (8 kg * 3 m + 10 kg * x2) / (8 kg + 10 kg)
Simplifying:
4.5 m = (24 kg + 10 kg * x2) / 18 kg
Multiplying both sides by 18 kg:
81 kg*m = 24 kg + 10 kg * x2
Subtracting 24 kg from both sides:
10 kg * x2 = 81 kg*m - 24 kg
Dividing both sides by 10 kg:
x2 = (81 kg*m - 24 kg) / 10 kg
Simplifying:
x2 = 8.1 m - 2.4 m
x2 = 5.7 m
(brainlest?) ples:(
Answer:
the 10 kg mass should be placed at x = -2.4 m to achieve a center of mass at y = 4.5 m.
Explanation:
To find the position along the x-axis where the 10 kg mass should be placed so that the center of mass is located at y = 4.5, we can use the principle of the center of mass.
The center of mass of a system is given by the equation:
x_cm = (m1x1 + m2x2) / (m1 + m2),
where x_cm is the x-coordinate of the center of mass, m1 and m2 are the masses, and x1 and x2 are the positions along the x-axis.
Given:
m1 = 8 kg,
x1 = 3 m,
m2 = 10 kg,
y_cm = 4.5 m.
To solve for x2, we need to find the x-coordinate of the center of mass (x_cm) by using the y-coordinate:
y_cm = (m1y1 + m2y2) / (m1 + m2),
where y1 and y2 are the positions along the y-axis.
Rearranging the equation and substituting the given values:
4.5 = (83 + 10y2) / (8 + 10).
Simplifying the equation:
4.5 = (24 + 10*y2) / 18.
Multiplying both sides by 18:
81 = 24 + 10*y2.
Rearranging the equation:
10*y2 = 81 - 24,
10*y2 = 57.
Dividing both sides by 10:
y2 = 5.7.
Therefore, the y-coordinate of the 10 kg mass should be 5.7 m.
To find the x-coordinate of the 10 kg mass, we can use the equation for the center of mass:
x_cm = (m1x1 + m2x2) / (m1 + m2).
Substituting the given values:
x_cm = (83 + 10x2) / (8 + 10).
Since the center of mass is at x_cm = 0 (the origin), we can solve for x2:
0 = (83 + 10x2) / (8 + 10).
Rearranging the equation:
83 + 10x2 = 0.
24 + 10*x2 = 0.
10*x2 = -24.
Dividing both sides by 10:
x2 = -2.4.

Assess It! Question #2: Which of the following statements about the Law
of Acceleration is true?
5 points
A: Increasing an object's mass decreases the amount of force required to move it
B: Decreasing the mass of an object increases its acceleration while force is
constant
C: Increasing the force applied to an object does not change its acceleration while
mass is constant
D: Decreasing the force applied to an object increases its acceleration while mass is
constant
Answers
Answer:
Statement B is the only true statement
"Decreasing the mass of an object increases its acceleration while force is constant."
Explanation:
Recall that Newton's 2nd Law states:
F = m * a
Therefore, if the force (F) is constant, and the mass (m) decreases, the acceleration (a) of the object must increase.
This agrees with the statement labeled as B: "Decreasing the mass of an object increases its acceleration while force is constant."
The true statement about the law of acceleration is that decreasing the mass of an object increases its acceleration while force is constant.
NEWTON'S LAW:
The relationship between the force, mass and acceleration has been explained by Newton in his law. The equation is as follows:Force = mass × accelerationAccording to the equation, the mass is inversely proportional to the acceleration. This means that as the mass increases, the acceleration decreases and vice versa. Therefore, the true statement about the law of acceleration is that decreasing the mass of an object increases its acceleration while force is constant.Learn more at: https://brainly.com/question/25116504?referrer=searchResults

Preconsciousness
The level immediately beneath aware is known as preconscious. Everything that is not in the conscious mind but may very simply be recalled and become conscious is included in the preconscious mind.

1. The statement is true. Projectiles are objects that are launched into the air and then follow a curved path under the influence of gravity and air resistance.
2. The statement is false. The horizontal component of the velocity is independent of the vertical component of the velocity, and they can have different values.
3. The statement is true. The formula Vx=Vø tan Ø is the formula for the horizontal component of the initial velocity of a projectile.
4. The statement is false. The velocity of a projectile is directed at an angle to the horizontal, with both horizontal and vertical components.
5. The statement is false. When no air acts on a projectile, its horizontal acceleration is zero, because there is no force acting in the horizontal direction. The vertical acceleration is still due to gravity.
6. The statement is true. A stone thrown into the air follows a curved path under the influence of gravity, making it an example of projectile motion.
7. The statement is false. The time to reach the top of the projectile's path depends on the initial velocity and angle of launch, as well as the acceleration due to gravity. The time to reach the top can be calculated using the formula t = Vy/g, where Vy is the vertical component of the initialvelocity, g is the acceleration due to gravity, and t is the time. Using this formula, the time to reach the top of the projectile's path can be calculated as:
t = Vy/g = Vø sin Ø/g = (100 ft/s)(0.5)/(32.2 ft/s²) = 1.55 s (approx.)
Therefore, the statement is false.

The y-component of the vector is approximately 14.67 meters.
To find the y-component of the vector, we need to use trigonometry. Given that the vector has a magnitude of 34 meters and an angle of 26 degrees, we can break down the vector into its x and y components.
Step 1: Identify the known values:
Magnitude of the vector (r) = 34 meters
Angle (θ) = 26 degrees
Step 2: Determine the y-component using trigonometry:
The y-component can be found using the formula:
y = r * sin(θ)
Step 3: Calculate the y-component:
Substituting the known values into the formula:
y = 34 * sin(26 degrees)
y ≈ 14.67 meters
Therefore, the y-component of the vector is approximately 14.67 meters.
