lab-3 (ol) periodic and simple harmonic motion – using phet rev 7-15-2020 objectives to study simple harmonic motion, and to determine the value of acceleration due to gravity by using a simple pendulum. also, to verify the equation for time period for a vertical spring-mass system.
Answers
A whole oscillation, cycle, or vibration, for instance, is the movement from y = A to y = +A and back to y = A. The period is the amount of time T needed to finish one oscillation.
Simple harmonic motion, or SHM, is a specific type of repetitive or periodic motion that describes the oscillation of the pendulum. The oscillating object's position changes sinusoidally throughout time. Many things go back and forth. A youngster swinging can be thought of as basic harmonic motion since the motion is approximatively sinusoidal. Simple harmonic motion does not include some complex motions, such as turbulent ocean waves.
When an item is in simple harmonic motion, it is simple to calculate both its position in relation to time and the rate at which it oscillates back and forth. In this lab, you will examine two simple harmonic motion examples: a simple pendulum and a spring-mass system.
A particle in simple harmonic motion that vibrates vertically goes up and down between two extremes when y = A. The amplitude is the largest displacement, A.
A whole oscillation, cycle, or vibration, for instance, is the movement from y = A to y = +A and back to y = A.
The period is the amount of time T needed to finish one oscillation. The frequency f, or number of vibrations the system makes per unit of time, is a related quantity. The unit of measurement for frequency is Hertz (abbreviated as Hz), with 1 Hz equal to one second. Frequency is the reciprocal of time.

6. If the energy removed from an engine as heat during one cycle is 6.0 × 10³ J, how
much energy must be added to the engine during one cycle in order for it to
operate at 31 percent efficiency?
Answers
To solve this question, we need to use the formula for efficiency, which states that Efficiency = (Output Energy / Input Energy) x 100.
We know that the Output Energy is 6.0 × 10³ J, and we need to figure out the Input Energy. To find the Input Energy, we can rearrange the formula to Input Energy = (Output Energy / Efficiency) x 100.
Plugging in our values, we have Input Energy = (6.0 × 10³ J / 0.31) x 100 = 19.35 x 10³ J.
Therefore, the energy that must be added to the engine during one cycle in order for it to operate at 31 percent efficiency is 19.35 x 10³ J.
As a young boy swings a yo-yo parallel to the ground and above his head, the yo-yo has a centripetal acceleration of 250 m/s2 . If the yo-yo’s string is 0.50 m long, what is the yo-yo’s tangential speed?
Answers
Centripetal acceleration ac is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity (tangential speed) v and has the magnitude:
\(a_c = \dfrac{v^2}{R}\)
Solving for v:
\(v = \sqrt{a_c R} = \sqrt{(250\;m/s^2)(0.50\;m)} = 5\sqrt{5}\;m/s \approx 11.18\;m/s\)
The yo-yo’s tangential speed 11.18 m/sec.
What is speed?The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.
Centripetal acceleration ac is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity (tangential speed) v and has the magnitude:

what is the wavelength of a 2.6 mhz ultrasound wave traveling through aluminum?
Answers
The wavelength of a 2.6 MHz ultrasound wave traveling through aluminum is 0.06 mm.
We know that the speed of sound in aluminum (v) is 6420 m/s. This value can be looked up in a table or provided in the question. The formula to find the wavelength of a wave is:
Wavelength (λ) = speed (v) / frequency (f)
where λ is measured in meters, v is measured in meters per second, and f is measured in hertz.
To use this formula, we need to convert the frequency of the ultrasound wave from megahertz (MHz) to hertz (Hz):
2.6 MHz = 2,600,000 Hz
Now we can plug in the values and solve:
λ = v / f
λ = 6420 m/s / 2,600,000 Hz
λ ≈ 0.00006 m or 0.06 mm (rounded to two decimal places)
Therefore, the wavelength of a 2.6 MHz ultrasound wave traveling through aluminum is 0.06 mm.

how much heat needs to be removed from 100 g of 85°c water to make -5°c ice?
Answers
The amount of heat that needs to be removed from 100 g of 85°c water to make -5°c ice is 70194 J of heat.
What is the heat change when 100 g of 85°C water changes to -5°C ice?The amount of heat that needs to be removed is calculated below.
Heat changes involved are as follows:
Heat change from water at 85°C to water at 0°C = mc₁ΔT₁
Heat change from water at 0°C to ice at 0°C = mL
Heat change from ice at 0°C to ice at -5°C = mc₂ΔT₂
where
m is mass = 100 g
c₁ is the specific heat capacity of water = 4.184 J/g/K
ΔT₁ is temperature change = 85°C
L is the latent heat of fusion of ice = 336 J/g
c₂ is the specific heat capacity of ice = 2.06 J/g/K
ΔT₁ is temperature change = 5°C
Heat change = (100 * 85 * 4.184) + (100 * 336) + (100 * 5 * 2.06)
Heat change = 70194 J

x0=0
x=?
v0x=10 m/s (moving horizontally)
v0y=0
x=x0+v0xt
x=10t
y=y0+1/2at^2
solve for t
0=y0-1/2gt^2
(a is acceleration which is - gravitational acceleration )
t=\(\sqrt{\frac{2y0}{g} }\)
plug into x equation
x=10(\(\sqrt{\frac{2y0}{g} }\)) where y0=100m and g=9.80 m/s^2
x= 45.2 m
if you check the distance when v0=5 m/s, we get x=22.5 m so the equation is correct. however if the g your class uses is 10.00 m/s^2, then we get x=22.4 for the first velocity and 44.7 for the second velocity

if you remove ice cubes from the freezer with wet hands, the cubes often freeze to your fingers. how can the ice freeze the water on your hands? shouldn’t they melt instead?
Answers
Ice cubes freeze water on wet hands due to heat transfer, causing the water to freeze and stick to the cold surface.
At the point when you contact an ice block with wet hands, the water on your hands shapes a meager layer on the outer layer of the ice 3D square. This layer of water freezes immediately because of the super chilly temperature of the ice, making a meager layer of ice on your skin.
The ice shape can freeze the water on your hands since it is a lot colder than the edge of freezing over of water, which is 0°C (32°F). Despite the fact that the ice block is colder than the edge of freezing over of water, it doesn't make the water on your skin freeze strong in light of the fact that your body is continually producing heat, which assists with keeping the water in a fluid state.
Notwithstanding, assuming the temperature of your skin drops adequately low, the water will freeze strong. For this reason it is vital to eliminate ice 3D shapes from the cooler with dry hands to keep the water from sticking to your skin.
It is a typical misguided judgment that the ice ought to soften when it comes into contact with the warm skin, however as a general rule, the temperature contrast between the ice and the skin is sufficiently huge to make the water on the skin freeze, instead of dissolve the ice.

In our solar system, evolvement and destruction of celestial bodies take place regularly at irregular intervals. Old planets and stars bursts out with a explosion, then they heat up so immensely or just scatter into pieces of rocky substance or smoky particles or just ice particles. But if they heat up, they change into dwarf stars when they lose their path of revolve. Any celestial body is dwarf when it losses their path.

How much gravitational energy does a 65 kg skydiver have 650 m up in the sky?
Answers
Answer:
G.P.E = 414050 Joules or 414.05 Kilojoules
Explanation:
Given the following data;
Mass = 65 kg
Height = 650 m
We know that acceleration due to gravity is equal to 9.8m/s²
To find the gravitational potential energy;
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;
\( G.P.E = mgh\)
Where;
G.P.E represents potential energy measured in Joules.m represents the mass of an object. g represents acceleration due to gravity measured in meters per seconds square. h represents the height measured in meters.Substituting into the equation, we have;
\( G.P.E = 65 * 9.8 * 650 \)
\( G.P.E = 414050 \)
G.P.E = 414050 Joules or 414.05 Kilojoules.
