A boundary with a small opening. There is a vector straight from the opening labeled D and an angle labeled theta to another ray, both striking a surface with a red point. The distance between the two red points is labeled y. A laser diffraction pattern results in y = 6.0 cm, and the distance from the gap to the screen is D = 12 cm. The tangent of θ would be equal to . Calculating the inverse (tan–1) of the value for the tangent of θ would give us a diffraction angle, θ, of degrees.

QUESTION 1
The two human thighbones (femurs) each have a cross-sectional area of 10 cm and they support
the upper part of a human body of mass 40kg. Calculate the average pressure sustained by each of
the femurs. (1mk)​

Answers

Answer:

2 * 10^5 pa

Explanation:

Pressure = Force / Area

Each thigh bone has a cross sectional area of 10cm²

Both thigh bones :

2 * 10cm² = 20cm²

To m² : 20 * (0.01)²

20 * 0.0001 m² = 0.002 m²

Force = mass * acceleration due to gravity(g)

g = 10m/s² ;

Force = 40 * 10 = 400N

Pressure = 400 N / 0.002 m²

Pressure = 200,000 N/m² = 2 * 10^5 pascal

If a sound wave has a wavelength of 0.790 meters, and is travelling at a speed of 355 m/s, what is the period of oscillation for this wave?

Answers

Wavelength=velocity/frequency
Time a.k.a period = 1/frequency

Step 1: solve for frequency using the first equation
0.79m = 355/frequency
Frequency=280.45 Hz

Step 2: solve the period using the second equation

1/280.45 = 0.00357=3.57*10^-3 seconds

A form of energy NOT associated with the particles of objects is
thermal energy
mechanical energy
nuclear energy
chemical energy

Answers

Answer:

mechanical energy

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states.

Generally, matter exists in three (3) distinct or classical phases and these are;

1. Solid: it is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.

2. Liquid: it is the state of matter in which the physical substance can be poured and it takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.

3. Gas: it is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.

Generally, the form of energy associated with the particles of objects include thermal energy, nuclear energy and chemical energy.

However, a form of energy not associated with the particles of objects such as an atom is mechanical energy.

Hope this helps :]

While at the county fair, you decide to ride the Ferris wheel. Having eaten too many candy apples and elephant ears, you find the motion somewhat unpleasant. To take your mind off your stomach, you wonder about the motion of the ride. You estimate the radius of the big wheel to be 15 m, and you use your watch to find that each loop around takes 23 s.A. What is your speed?
B. What is the magnitude of your acceleration?
C. What is the ratio of your weight at the top of the ride to yourweight while standing on the ground?
D. What is the ratio of your weight at the bottom of the ride toyour weight while standing on the ground?

Answers

Answer:

Explanation:

From the given information:

radius = 15 m

Time T = 23 s

a) Speed (v) = [tex]\dfrac{2 \pi r}{T}[/tex]

[tex]v = \dfrac{2\times \pi \times 15}{23}[/tex]

v = 4.10 m/s

b) The magnitude of the acceleration is:

[tex]a = \dfrac{v^2}{r} \\ \\ a = \dfrac{(4.10)^2}{15}[/tex]

a = 1.12 m/s²

c) True weight = mg

Apparent weight = normal force

From the top;

the normal force = upward direction,

weight is downward as well as the acceleration.

true weight - normal force = ma  

apparent weight =mg - ma  

[tex]\dfrac{apparent \ weight}{true \ weight} = \dfrac{(mg - ma)}{(mg)}[/tex]

[tex]=1- \dfrac{1.12}{9.8}[/tex]

= 0.886 m/s²

d)

From the bottom;

acceleration is upward, so:

apparent weight - true weight = ma

apparent weight = true weight + ma

[tex]\dfrac{apparent \ weight }{true \ weight} =\dfrac{ mg + ma}{mg}[/tex]

[tex]\dfrac{apparent \ weight }{true \ weight} =1+ \dfrac{a}{g} \\ \\ = 1 + \dfrac{1.12}{9.8}[/tex]

[tex]= 1 + \dfrac{1.12}{9.8} \\ \\[/tex]

= 1.114 m/s²

ohm found that current, voltage, and resistance in a circuit are always related in the same day.

ohms obersivations

ohms found that if the factors that affect resistance are held constant, the resistance of most conductors does not depend on the voltage across them charging the voltage in a circuit changes the current but does not change the resistance regardless of the applied voltage. the ohms law resistance in a circuit is equal to voltage divided by current

resistance =current or voltage =current × resistance

The speed of light in air is 3.00 x 10^8 m/s. If a light wave has a wavelength of 5.80 x 10^-7m, what is its frequency?

Answers

Answer:

5.17 x 10^14 1/s

Explanation:

Equation:

c = λ f

c = speed of light

λ = wavelength

f = frequency

Solve:

3.00 x 10^8 m/s = (5.80 x 10^-7m) * f

f = (3.00 x 10^8 m/s) / (5.80 x 10^-7m)

f = 5.17 x 10^14 1/s

What would the volume of a gas be at –125oC, if it had a volume of 693 mL at 45oC?

Answers

Answer:

322.5mL

Explanation:

According to Charles's law, which state that at constant pressure the volume of fixed mass of a gas is proportional directly to it's temperature.

This can be expressed as

V1/ T1 = V2 / T2

Where

V1= initial volume= 693 mL

V2= final volume

T2= final temperature=( –125°C + 273)= 148K

T1= initial temperature= (45°C+ 273)=318K

V1/ T1 = V2 / T2

693/318 = V2/148

693×148 = 318 × V2

V2=102564/318

= 322.5mL

please help me guys will give brainliest and lots of points

Answers

Answer: The 180-Hz sinusoid is called the third harmonic, since its frequency is three times that of the fundamental frequency.

Explanation: Harmonics are integer multiples of the fundamental frequency. For example, if the fundamental frequency is 50 Hz (also known as the first harmonic) then the second harmonic will be 100 Hz (50 * 2 = 100 Hz), the third harmonic will be 150 Hz (50 * 3 = 150 Hz), and so on.

What is Electromagnet?

Permanent magnets are not the same as electromagnets. Coils of wire with electricity running through them make up electromagnets. An electromagnet's wire coils act like magnets when an electric current flows through them because moving charges produce magnetic fields.

The coils stop functioning as a magnet when the electricity is turned off. When magnetic forces are only required for brief periods of time, electromagnets are frequently used in electrical equipment.

They both make use of electromagnets, which use electricity to apply a magnetic field. Extremely strong electromagnets are used by wrecking yards to transfer heavy scrap metal or even entire cars from one location to another.
