The force used to move a body from one location to another is referred to as work. An energy transfer takes place whenever a force is applied. The force produces 1000 J of work.

Because the force is parallel to a horizontal table in this instance, the angle between the force and the displacement is 0 degrees. The value of the cosine at 0 degrees will be 1. So, the force can be determined as follows:

Work = Force, Distance, and Cosine.

Work = Force x Distance x One

Work Equals Force times Distance

Being:

Power = 50 N

Distance = 20 kg, resulting in:

Work = 20 kg x 50 N

Work= 1000 J

The piece is 1000 J in total.

Given the following information:Mass of the system, m = 20 kg.Damping coefficient, b = 6 Ns/m.Force, F = 90 N.Frequency of applied force, f = ?Applied force angular frequency, w = 6 rad/s.Forced vibration equation:F(t) = F0 sin(wt)where F0 = 90 N and w = 6 rad/s.Under the action of the force F, the mass m will oscillate.The equation of motion for the mass-spring-damper system is given by:$$\mathrm{m\frac{d^{2}x}{dt^{2}}} + \mathrm{b\frac{dx}{dt}} + \mathrm{kx = F_{0}sin(\omega t)}$$where k is the spring constant.x(0) = 0 and x'(0) = 0.As we have the damping coefficient (b), we can calculate the damping ratio (ζ) and natural frequency (ωn) of the system.Damping ratio:$$\mathrm{\zeta = \frac{b}{2\sqrt{km}}}$$where k is the spring constant and m is the mass of the system.Natural frequency:$$\mathrm{\omega_{n} = \sqrt{\frac{k}{m}}}$$where k is the spring constant and m is the mass of the system.Resonant frequency:$$\mathrm{\omega_{d} = \sqrt{\omega_{n}^{2}-\zeta^{2}\omega_{n}^{2}}}$$At resonance, the amplitude of the system will be maximum when forced by a sinusoidal force of frequency equal to the resonant frequency.Resonant frequency:$$\mathrm{\omega_{d} = \sqrt{\omega_{n}^{2}-\zeta^{2}\omega_{n}^{2}}}$$$$\mathrm{\omega_{d} = \sqrt{(6.57)^{2}-(-2.88)^{2}} = 6.98 rad/s}$$Hence, the frequency of applied force at which resonance will occur is 6.98 rad/s.

The frequency of the applied force at which resonance will occur is ω = 2√5 rad/s.

To determine the frequency of the applied force at which resonance will occur, resonance happens when the frequency of the applied force matches the natural frequency of the system. The natural frequency can be determined using the formula:

ωn = √(K / M),

where ωn is the natural frequency, K is the spring constant, and M is the mass of the system.

Substituting the given values of K = 400 N/m and M = 20 kg into the equation, we can calculate the natural frequency ωn.

ωn = √(400 N/m / 20 kg) = √(20 rad/s²) = 2√5 rad/s.

Therefore, the frequency of the applied force at which resonance will occur is ω = 2√5 rad/s.

The correct question is given as,

Answer:

(b) is false - a person on the moon would weight about 1/6 of the person's weight on earth - this is due to the smaller gravitational attraction of the person's mass even tho the mass is the same

The statement that is false is "b. weight is a constant no matter where you are located." Statements a, b and c are all true.

This is because weight is a measure of the force of gravity on an object, and the force of gravity varies depending on where you are located.

For example, an object will weigh less on the moon than it does on Earth because the force of gravity is weaker on the moon.

In contrast, mass is a measure of the amount of matter in an object and does not change depending on location.

Therefore, statements "a. weight depends on the force of gravity," "c. mass is a constant no matter where you are located," and "d. mass is the amount of matter in an object" are all true.

Explanation:

It would take approximately 3.66 seconds for the 200-W electric immersion heater to heat the 0.250 kg of water.

To determine the time required for the electric immersion heater to heat the water, we can use the formula: Energy (Joules) = Power (Watts) × Time (seconds). Given: Power = 200 W, Mass of water = 0.250 kg.

First, we need to calculate the energy required to heat the water. The specific heat capacity of water is approximately 4.18 J/g·°C.

Energy = Mass × Specific heat capacity × Temperature change

Assuming the temperature change is from room temperature (around 25°C) to the desired coffee temperature (let's say 95°C):

Energy = 0.250 kg × 4.18 J/g·°C × (95°C - 25°C)

Energy = 0.250 kg × 4.18 J/g·°C × 70°C

Energy = 732.50 J

Now, we can rearrange the formula to find the time: Time (seconds) = Energy (Joules) / Power (Watts)

Time = 732.50 J / 200 W

Time ≈ 3.66 seconds

Therefore, it would take approximately 3.66 seconds for the 200-W electric immersion heater to heat the 0.250 kg of water.

The kinetic energy (KE) of an object is given by the formula:

KE = (1/2)mv^2

where m is the mass of the object and v is its velocity.

Given that the boat has a kinetic energy of 52,000 J and a mass of 39,000 kg, we can rearrange the formula to solve for v:

v = sqrt(2KE/m)

Substituting the values, we get:

v = sqrt[(2 x 52000 J) / 39000 kg]

v = sqrt(104000 J / 39000 kg)

v = sqrt(2.6667 J/kg)

v = 1.632 m/s

Therefore, the boat is moving with a velocity of approximately 1.632 m/s.

The pH of the solution is approximately 2.919.

To determine the pH of the solution, we need to consider the dissociation of HF (hydrofluoric acid) and the equilibrium between HF and its conjugate base, F^-.

HF can dissociate according to the equation: HF ⇌ H^+ + F^-

Given that the solution is 0.25 M in HF and 0.15 M in F^-, we can assume that HF is the predominant species and the concentration of F^- is relatively low. Therefore, we can consider HF as the acid and F^- as the conjugate base.

The pKa of HF is given as 3.14. The pKa is a measure of the acid's strength, and it is related to the equilibrium constant for the dissociation reaction. In this case, pKa = -log(Ka), where Ka is the acid dissociation constant.

Using the Henderson-Hasselbalch equation, pH = pKa + log([A-]/[HA]), we can calculate the pH of the solution.

pH = 3.14 + log(0.15/0.25) ≈ 3.14 + (-0.221) ≈ 2.919

Therefore, the pH of the solution is approximately 2.919.

It reveals that light is a wave

Explanation:

Diffraction is the property of a wave in which there is a bending of the wave about the corners of an obstacle or aperture into the geometrical shadow of the obstacle or aperture.

This simply implies that a wave bends or spreads out when it passes through openings. Since the light diffracts through small slits and diffraction has been shown to occur in water waves and sound waves, this property of diffraction can only be characteristic of a wave and thus, this evidence reveals that light is a wave.

Answer:

It shows that light can travel in different wavelengths.

Explanation:

Light is similar to a wave in the way that it travels in a straight line, but when it is passing through the slits, it diffracts due to this difference. Therefore, light refracts in the same way as a wave would, and it is a mode of transferring energy. The light travels in a way similar to a wave

At different stages of development, infants use different perceptual systems to coordinate grasping.This enables them to interact effectively with their environment and learn from their experiences.

Infants' grasping abilities develop and change over time, and at each stage, they rely on different perceptual systems to coordinate their grasp. For example, in the early stages, infants use their visual system to guide their grasp, while later on, they also incorporate tactile and proprioceptive information to refine their grasp. Additionally, infants do not always grasp small objects with all fingers or both hands, as their grasp depends on the size and shape of the object.

During infancy, children go through various stages of development, and their perceptual systems, such as vision, touch, and proprioception, play a crucial role in coordinating grasping.

C is the correct answer of this question.

The system described by the transfer function G(s) = -co² s² + 2a + w², with a damping ratio of 1.3 and a natural frequency of 0.5, has an overdamped unit step response. So, the correct option is (E)

The transfer function of the system is given as G(s) = -co² s² + 2a + w², where co represents the damping ratio, a represents an arbitrary constant, and w represents the natural frequency of the system. We are given that the natural frequency is 0.5 and the damping ratio is 1.3.

To determine the type of unit step response, we need to analyze the damping ratio (co) in relation to the critical damping value (co_critical).

The critical damping ratio (co_critical) is defined as the value where the system is on the threshold between being overdamped and underdamped. It is given by the formula co_critical = 2 * sqrt(a * w²).

In our case, the natural frequency (w) is 0.5, so we can calculate co_critical as follows: co_critical = 2 * sqrt(a * 0.5²).

Since the damping ratio (co) is given as 1.3, we can compare it with co_critical to determine the type of unit step response.

If co > co_critical, the system is considered overdamped (Option E).

If co = co_critical, the system is considered critically damped (Option D).

If co < co_critical, the system is considered underdamped (Option C).

Based on the given values, we can determine that the system is overdamped (Option E) because the damping ratio (1.3) is greater than the critical damping ratio.
