The frequency of a sinusoidal signal can be determined by calculating the time period between two consecutive peaks and taking the reciprocal of that value.

In this case, the time difference between the first peak at -8 ms and the second peak at 2 ms is 10 ms. Therefore, the time period of the signal is 10 ms.

To find the frequency, we take the reciprocal of the time period, which gives us 1/10 ms. Simplifying this, we convert the time period to seconds by dividing it by 1000, resulting in 1/0.01 s. Evaluating this expression, we find that the frequency of the sinusoidal signal is 100 Hz. This means that the signal completes 100 cycles per second, indicating a high frequency for the given waveform.

The torque required to turn the camshaft without friction is 0 N-m. When friction is neglected, no external rotational force is needed to turn the camshaft as there is no resistance to overcome.

Torque is a measure of the rotational force applied to an object. In this case, neglecting friction means that there are no external forces resisting the rotation of the camshaft. Therefore, no torque is required to turn the camshaft. Friction is the force that opposes the motion of two surfaces in contact, and neglecting it means assuming that there is no resistance caused by friction.

When there is no friction, the camshaft can rotate freely without any additional torque being applied. This is because torque is only required to overcome the resistance caused by friction. In the absence of friction, the camshaft will experience no resistance and can rotate effortlessly.

Friction plays a crucial role in many mechanical systems, as it affects the efficiency and performance of various components. However, in this specific scenario where friction is neglected, the torque required to turn the camshaft becomes zero.

Explanation:

The new electrostatic force will be 384 units.  

The electrostatic force of attraction between two charges \(q_{1} \\\)(charge of object 1)  and \(q_{2}\)(charge of object 2) separated by a distance d is given by

\(F = \frac{q_{1} q_{2}}{4\pi E_{0} d^{2} } \\\)

\(E_{0} = 8.854 * 10^{-12} C^{2} N^{-1} m^{-1}\) is the permittivity of free space.

Initially, we have,

\(\frac{q_{1} q_{2}}{4\pi E_{0} d^{2} } =F_{1} = 8 units\)  

Now, if the charge of object 1 is multiplied by 1, the charge of object 2 is multiplied by 3, and the distance separating objects 1 and 2 is divided by 4, we have, \(q_{1} =q_{1}, q_{2} =3q_{2} , d=\frac{d}{4}\).

The new electrostatic force will be,

\(F_{2} = \frac{q_{1} 3q_{2}}{4\pi E_{0} (\frac{d}{4} )^{2} } \\\\\) units.

We have, \(F_{1} = 8 units= \frac{q_{1} q_{2}}{4\pi E_{0} d^{2} } \\\)

Hence,

\(F_{2} =\frac{8*3}{(\frac{1}{4}) ^{2} } units= 384 units.\)

Answer and Explanation:Option A->The innermost layer of the earth is known as the core. It is divided into inner core and outer core. It comprises of a high concentration of nickel and iron.

The length of time between when air passes through the lips and when the vocal cords start vibrating is referred to as the voice onset time (VOT). It's also known as the aspiration interval, the lag time, or the lead time.

Voice onset time is the amount of time that elapses between the release of a stop consonant, such as /p/, /b/, /t/, /d/, /k/, /g/, and /q/ and the start of vocal cord vibration. Voice onset time can be calculated by examining the waveform and spectrogram of a spoken phrase with a stop consonant. The VOT varies depending on the language being spoken, as well as the specific consonant in question and the phonetic environment in which it is pronounced.Voice onset time can be used to distinguish between different categories of consonants. A shorter voice onset time is usually connected with voiced consonants, while a longer voice onset time is typically linked with voiceless consonants. For example, the voice onset time for the voiced consonant /b/ is usually shorter than the voice onset time for the voiceless consonant /p/.

In summary, voice onset time (VOT) is the time between when air passes through the lips and when the vocal cords start vibrating. It can be used to differentiate between voiced and voiceless consonants and varies depending on the language, the specific consonant, and the phonetic environment.

The maximum instantaneous power is zero for a single-phase circuit with an inductive load.

For the single-phase circuit with an inductive load, (resistor and inductor), the maximum instantaneous power is zero. When we study an inductive load, we come to know that it consumes real power as well as reactive power. The reactive power is not useful in an electrical circuit, it is useful for creating and maintaining magnetic fields in inductors, transformers, and motors. So, for the single-phase circuit with an inductive load, (resistor and inductor), the maximum instantaneous power is zero.

They can be used for motors, lights, and other loads which require less power. The power factor of a circuit is the ratio of the real power (P) to the apparent power (S). It is the power that is actually used to do the work. The apparent power is the power that is drawn from the circuit, it consists of real power and reactive power. Therefore, the maximum instantaneous power is zero for a single-phase circuit with an inductive load.

Answer:

Debt payments to income ratio = 22.74%

Explanation:

Debts payment to Income ratio is calculated as follows:

= \frac{Total\ debt\ payment}{Total\ Income}

Total Income

Total debt payment

We have total debts payment = auto loan payment 685 + student loan payment685+studentloanpayment375 + credit card payment 125 =125=1,185

Total Income = $5,210

Note: Credit card is also a kind of debt as firstly all the expenses are met during the period and then the payment is made at the end of the period, therefore, there is a loan in the period. Therefore, it will be considered for payment of debt.

Debt payments to income ratio = \frac{1,185}{5,210} = 22.74

5,210

1,185

=22.74

That means the debts are 22.74% of income.

Answer:

The experiments are not shown, so I will answer in a general way.

By the first Newton's law, an object will only change it's velocity if there is a net force different than zero acting on the object.

Then in the experiments (depending on the experiment), you can see different things.

If an object is not moving and you apply a force in it, the object will move.

If an object is moving and you apply a force in the opposite direction of it's motion, the motion will: decrease the speed, stop at all, or move in the opposite direction. Depending on the force that you apply.

An excellent experiment (but hard to do) is dropping an object from a really high place.

The gravitational force will pull down the object and the object will start to increase it's velocity.

But there is the air resistance, that opposes to this motion and increases with the speed of the object.

Then there is a given speed such that the air resistance force will be equal to the gravitational force, then we have a balanced force (the net force is zero) which means that the object will keep falling at a constant velocity.

Answer:

Explanation:

Since the fans are blowing in opposite directions, the net force stays the same and so does the velocity. (I wrote this and got it right)

Answer:

10.466

Explanation:

I used pythagorean theorem. It is A^2 + B^2 = C^2 then square root of C^2 to find C which was 10.466.

(A) The individual receives an impulse from the ground because an impulse is equal to a change in momentum, and when a person jumps up from the ground, their momentum changes.

(b) The individual is affected by the floor, yes. When a force works over a distance, work is produced; in this instance, the floor pushes the person upward over a distance equal to the height of the leap.

(C) The equation p = mv, where m is the person's mass and v is their forward velocity, determines the momentum of the subject prior to jumping. The person's initial momentum was zero since they were at rest when they jumped.

The momentum of the person after they leave the floor is also given by p = mv, where m is the mass of the person and v is their velocity after jumping. We can use conservation of energy to find their velocity after jumping:

\(mgh = (1/2)mv^2\)

Here g is the acceleration due to gravity, h is the height that the person jumps, and the factor of 1/2 comes from the fact that the person starts from rest. Solving for v, we get:

v = \(\sqrt{(2gh)}\)

v = \(\sqrt{(2 * 9.8 * 0.149 m)}\) ≈ 1.94 m/s

So the momentum of the person after leaving the floor is:

p = mv = (60.0 kg)(1.94 m/s) ≈ 116.4 kg m/s

(d) No, it doesn't make sense to say that the momentum came from the floor. Momentum is always conserved, so the person's momentum after jumping must be equal to their momentum before jumping. In this case, the person's momentum before jumping was zero.

(e) The kinetic energy of the person after leaving the floor is given by:

KE = \((1/2)mv^2\), where m is the mass of the person and v is their velocity after jumping. Plugging in the given values, we get:

KE = \((1/2)(60.0 kg)(1.94 m/s)^2\) ≈ 354 J

(f) No, it doesn't make sense to say that the energy came from the floor. Energy is always conserved, so the person's kinetic energy after jumping must be equal to the work done on them by external forces. In this case, the only external force doing work on the person is gravity.

To derive the equations needed to find a solution to the problem using Euler's scheme, we'll discretize the time variable and approximate the derivatives.

Let's assume we divide the time interval into small steps of size Δt.

Discretization of Time:

Let t_i represent the i-th time step, where i = 0, 1, 2, ... represents the time index. We can define t_i as t_0 + iΔt, where t_0 is the initial time and Δt is the time step size.

Discretization of x(t):

Let x_i represent the displacement of the mass at time t_i. Similarly, x_i+1 represents the displacement at the next time step t_i+1.

Approximation of the Second Derivative:

Using Euler's finite difference approximation, we can approximate the second derivative of x with respect to time as follows:

d^2x/dt^2 ≈ (x_i+1 - 2x_i + x_i-1) / Δt^2,

where x_i+1 and x_i-1 are the displacements at the next and previous time steps, respectively.

Equation for the Spring-Mass System:

Substituting the approximation of the second derivative into the equation m(d^2x/dt^2) + kx = 0, we get:

m(x_i+1 - 2x_i + x_i-1) / Δt^2 + kx_i = 0.

Rearranging the equation, we have:

x_i+1 = (2 - kΔt^2/m)x_i - x_i-1.

This is the equation that relates the displacement of the mass at the current time step (x_i+1) to its displacements at the previous time steps (x_i and x_i-1).

By iteratively solving this equation for each time step, starting from an initial condition x_0 and using appropriate boundary conditions (e.g., x_0 and x_1), we can find the numerical solution to the spring-mass system using Euler's scheme.
