A 60.0-cm long string with a mass 8.00 g has a tension 200 n. what is the fundamental frequency of this string?
The fundamental frequency is 102.06 Hz m/s.
We need to know about the fundamental resonant frequency to solve this problem. When the string is vibrating at its lowest resonant frequency, it should follow the rule

The average acceleration of the ball, while it is in contact with the wall, is -3969.27 m/s².
Acceleration is the rate of change of velocity per unit of time. Its S.I. unit is m/s². It is equal to the change in velocity divided by the time taken to change the velocity.
Acceleration a = Change in velocity/ Time taken
Given in the question
Initial Velocity = u = + 20.6 m/s ( towards the wall is positive direction )
Final Velocity = v = - 11.948 m/s (away from the wall is negative direction)
Change in Velocity = Final Velocity - Initial Velocity
= (- 11.948) - ( + 20.6)
= -11.948 - 20.6
= -32.548 m/s
So Change in velocity = 32.548 m/s
Time Taken = Time of contact with the wall
= 0.0082 seconds
Put in the Formula: a = Change in velocity/ Time taken
a = -32.548/0.0082
a = -3969.27 m/s²
Therefore the average acceleration of the ball, while it is in contact with the wall, is -3969.27 m/s².

What is the displacement of the object from the equilibrium position at time t=1.5s. Give your answer in meters, to one significant figure and without a unit
The correct answer is The object must be at equilibrium position. So, the displacement is obtained zero.
Given,
The simple harmonic motion has a time period of T = 2s
The amplitude of oscillation is A = 0.5 m
The displacement of the object from the equilibrium position at time t= 1.5 s should be determined.
At time t = 0 , the displacement of the object is maximum. For objects in SHM, the maximum displacement is equal to its amplitude.
The general equation of a particle in simple harmonic motion can be written as x = A sin(ωt + Φ) where A is the amplitude ω = 2π/T is the angular frequency and Φ is its initial phase which can be determined considering time t= 0 as follows,
x = A sin(ωt + Φ)
A = A sin ( ω × 0 + Φ )
sin Φ = 1
Φ = π/2
Therefore, the equation of the object in SHM becomes,
x = A sin(ωt + π/2)
x = A cos ωt ______(1)
Substituting, t = 1.5s the displacement can be obtained as,

Furthermore, how can it calculate its profit if revenue is in u.s. currency and most of its costs are in canadian currency?
A company can calculate its profit by using the foreign currency exchange rates prevailing in the market. The cost incurred in foreign currency can be converted into domestic currency first. The spot rates prevailing in the market can be used for such conversion. Once the expenses are converted into the domestic currency, the profits can be computed in the normal manner as now both the revenues and the cost are in domestic currency.
What is meant by foreign exchange rate?Foreign Exchange Rate is defined as the cost of the residential currency with regard to another currency. The reason of foreign trade is to compare one currency with another for appearing their relative values.
Foreign exchange rate can also be said to be the rate at which one currency is traded with another or it can be said as the price of one currency that's expressed in terms of another currency.

The coal has 50 J of potential energy and no kinetic energy. It is burned in the power plant to produce electrical energy, but only 20 J of electrical energy is produced.
Which of the following may account for this?
Some of the coal's energy was destroyed by the fire.
Some of the coal's energy was turned into other forms.
The fire was used to create the electrical energy from scratch.
Some of the coal's energy was turned into other forms of energy.
What is conversion of energy?According to the first law of thermodynamics, energy can neither be created nor destroyed but is converted from one form to another. We know that from the first law of thermodynamics, the energy that originally in the coal does not vanish into thin air but undergoes a conversion.
Thus, want to find out what accounts for the energy of the coal. Thus, we could say that some of the coal's energy was turned into other forms as this is in consonance with the first la of thermodynamics.

At what temperature (degrees fahrenheit) is the fahrenheit scale reading equal to (a) 3 times that of the celsius and (b) 1/6 times that of the celsius?
45.7 °F is the Fahrenheit scale reading equal to 3 times that of the Celsius
-4 °F is 1/6 times that of the Celsius
Evaluating :
The relationship between temperature in degrees Fahrenheit, F, and degrees Celsius, C, is
F = 1.8°C + 32
Part a.
If F = 6°C, then
6°C = 1.8°C + 32
6°C - 1.8°C = 32
4.2°C = 32
C = 7.62
Therefore, F = 6×7.62 = 45.71
= 45.7 °F (nearest tenth)
Part b.
When F = (1/5)C, then
0.2°C = 1.8°C + 32
0.2°C - 1.8°C = 32
-1.6°C = 32
C = - 20
Therefore, F = 0.2 × -20 = -4
= -4 °F
What are Celsius and Fahrenheit scales?
Celsius and Fahrenheit are two scales won't to measure temperature. The temperature within the centigrade scale will be expressed in degrees Celsius. The temperature within the Fahrenheit scale will be expressed in degrees Fahrenheit. The relation between Celsius and Fahrenheit is proportional.
