A block is sitting on a small platform supported by a spring and is undergoing simple harmonic oscillation with a frequency of 4.5 Hz. What is the maximum amplitude at which the block will stay on the platform

Answers

Answer 1

For a block undergoing simple harmonic oscillation, the maximum amplitude is mathematically given as

a=0.0749m

What is the maximum amplitude at which the block will stay on the platform?

Generally, the equation for the maximum acceleration is mathematically given as

Ma=A*w^2

Where

A = 0.075 m

Therefore

0.075 * w^2 = 9.8

w = 11.43 rad/s

In conclusion, maximum frequency

mF=w/2pi

mF=11.43/2pi

mF= 1.82 Hz

Where

g=2\pif)^2a

a=(9.8)/4*\pi^2(1.82)^2

a=0.0749m

If the gravitational force on an object is directly proportional to its mass, why don’t objects with large masses fall with greater acceleration than small ones?.

Answers

Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.

Based on the information provided, the Power of the electric forklift to the nearest hundred is 12,000 W.

What is the formula for arriving at Power in physics?

The formula for calculating power in physics is given as:

P = E/t; where P = Power, E is energy and t is time in seconds. It is also given as :

P = W/Δt

Recall that power is defined as the amount of work done within a specific amount of time.

Where W = Work and; Δt = time elapsed.

Recall that Work (w) = Force x distance

Force here is usually domiciled in Newtons while distance is usually domiciled in meters.

7000 pounds or Lbs to Newtons is

7000 x 4.4482216153 = 31137.551307 N

So let's convert the distance to Meters.

1 foot = 0.3048m

Therefore, 76ft = 23.1648 m

Thus, Work = 31137.551307 X 23.1648 (That is Force in Newtons x distance in meters.)

Work = 721, 295.148516 N·m

Recall that power is given as:

P = W/Δt

= 721,300/60 seconds

= 12,021.6666667, to the nearest hundred, and we have:

P = 12,000 W

Which is an example of current electricity

Answers

Answer:

A or B you choose

Explanation:

This is called current electricity or an electric current. A lightning bolt is one example of an electric current, although it does not last very long. Electric currents are also involved in powering all the electrical appliances that you use, from washing machines to flashlights and from telephones to MP3 players.

what is an electrical current, amp, ampere Current is the flow of electrons. When a circuit is closed then a current of electrons can flow and when a circuit is open then no current can flow. We can measure the flow of electrons just like you can measure the flow of water through a pipe.

High energetic winds turning generator , causing electrons to flow into power lines is an example of current electricity. Remaining all are examples of static electricity .

What is current electricity ?

The movement of electrons from one area of the circuit to another is referred to as current electricity. Free electrons flow between two points when two bodies with different potentials are connected by a wire, until both objects reach the same potential, at which point the current stops.

Current flows until a potential difference exists throughout the conductor. The following techniques can be used to produce current electricity:

1. Through the passage of a metal wire through a magnetic field (Both alternating current and direct current can be generated by the following method)

2.Utilizing a battery and chemical reactions (Direct current can be generated through this method)

Here, the wind's kinetic energy provide the mechanical energy for the generator to to produce power lines. Hence option A is correct. All others are static electricity for short time only.

The voltage in american household is 120 v. however, because we use a/c power, the voltage is oscillating between two maximums. what is the maximum or peak voltage required to produce an average voltage of 120 v?.

Answers

Answer:

188 v

Explanation:

The average of a sine wave is .637 times the peak value

.637 x = 120

x = 120 / .637 = 188 v

The voltage in an American household is 120 v. however because we use a/c power, the voltage is oscillating between two maximums, then the maximum or peak voltage required to produce an average voltage of 120 Volts would be 76.44 Volts.

What is power?

The rate of doing work is known as power. The Si unit of power is the watt.

Power = work / time

The mathematical expression for the power is as follows

P = VI

As given in the problem, the voltage in American household is 120 v. however, because we use a/c power, the voltage is oscillating between two maximums.

The average voltage (VAV) of a sinusoidal waveform is determined by multiplying the peak voltage value by the constant 0.637, which is two divided by pi (π).

The maximum voltage = 120 × 0.637

                                      =  76.44 Volts
