The wavelength of the second laser is 0.170mm.

What is wavelength?
The distance over which a periodic wave's shape repeats is known as the wavelength in physics. It is a property of both travelling waves as well as standing waves in addition to other spatial wave patterns. It is the distance between two consecutive intersection point of the same phase just on wave, such as two adjoining crests, troughs, as well as zero crossings. The spatial frequency is the reciprocal of wavelength. The Greek letter lambda () is frequently used to represent wavelength. The term wavelength also is occasionally used to refer to modulated waves, their sinusoidal envelopes, or waves created by the interference of multiple sinusoids.

The distance between the successive maxima and minima of the interference pattern is given by the equation
d/λ = L sin θ

where θ is the angle between the slits and the screen. Since the second laser must produce a maximum at the same location as the fourth minimum of the first laser, the angle θ is equal to 4 times the angle between the first laser and the screen. Thus, the wavelength of the second laser is given by the equation

λ2 = (d/L) sin(4θ)
Substituting in the given values, we have
λ2 = (0.400mm/L) sin(4θ)
where θ is the angle between the first laser and the screen. The value of θ can be found using the equation
d/λ1 = L sin θ|
where λ1 is the wavelength of the first laser. Substituting in the given values, we have
θ = sin-1(d/λ1L)
Substituting this into the equation for λ2, we get
λ2 = (0.400mm/L) sin(4sin-1(d/λ1L))
Therefore, the wavelength of the second laser is given by
λ2 = (0.400mm/L) sin(4sin-1(d/0.400mm/8))
= 0.400mm sin(4sin-1(1/8))
= 0.400mm x 0.425
= 0.170mm
Therefore, the wavelength of the second laser is 0.170mm.

if the weight of the sdof is 20 kips and the stiffness is 50 kips/in, the natural frequency period of the structure is  12.5 seconds.

In structural dynamics, the natural frequency of a Single Degree of Freedom (SDOF) system is a characteristic property that describes how quickly the system oscillates or vibrates. The natural frequency is determined by the mass of the system and its stiffness.

To calculate the natural frequency, we need to convert the weight to mass and use the formula:

fn = 1 / (2π) * √(k / m)

First, let's convert the weight to mass:

Weight = mg

20 kips = m * 386.4 in/s² (acceleration due to gravity)

m = 20 kips / 386.4 in/s²

m = 51.73 lb/s²

Now, we can calculate the natural frequency:

fn = 1 / (2π) * √(k / m)

fn = 1 / (2π) * √(50 kips/in / 51.73 lb/s²)

fn ≈ 0.080 Hz

Finally, we can calculate the natural frequency period:

Period (T) = 1 / fn

T ≈ 1 / 0.080 Hz

T ≈ 12.5 seconds

Therefore, the correct natural frequency period of the SDOF structure is approximately 12.5 seconds.

C. Series

Consider resistors in a circuit - if all the resistors in the circuit are in series and one of the resistors fails then no current can flow thru the circuit,

If the resistors are in parallel then then each resistor experiences the same voltage drop regardless of whether or not any resistor in particular is carrying current.

If the resistors are connected in series, each one will receive the same pd drop, if withstanding if it is carrying current or not.

Option C is correct  Series

A circuit is simply defined as a  channel that must always be followed in order for electricity to flow and perform something good.

Answer:

B. 44.1

Explanation:

We can use the equation y=1/2gt^2 to find the distance in the vertical direction, where y= distance in the vertical direction, g=acceleration due to gravity, and t=time

we only know acceleration due to gravity(9.8m/s^2),

plug in known variables,

y=1/2*9.8*t^2

we still need to plug in the time variable.

In order to do that, we an use the s=d/t equation and re arrange that formula to get: t=d/s, where t=time, d=distance, and s=speed.

plug in known variables,

t=60/20

t=3

now that we know the time, we can plug that into our original equation

y=1/2*9.8*3^2

simplify,

y=4.9*3^2

y=4.9*9

y=44.1m

a. The third sphere must be placed between A and B, closer to A.

b.  the third sphere must be placed at 175 cm from the first sphere.

Since

Using Newton's law of universal gravitation, the net force on the first sphere on the third sphere is F = mAmC/x² where x = distance between sphere C and A

Also, the Force of attraction between there second sphere and the third sphere is F' = mBmC/(R - x)² where R = distance between mA and mB and x = distance between mA and mC.

Since the net force must be zero, then

F = F'

mAmC/x² = mBmC/(R - x)²

So, (R - x)²/x² = mB/mC/mAmC

(R - x)²/x² = mB/mA

Substituting the values of mA and mB into the equation, we have

(R - x)²/x² = 7/2

(R - x)²/x² = 3.5

(R - x)/x = √3.5

(R - x)/x = 1.87

R - x = 1.87x

R = x + 1.87x

R = 2.87x

x = R/2.87

x = 0.35R

Since x = 0.35R, the third sphere must be placed between A and B, closer to A.

Since the position of the third sphere is

So, x = 0.35 × 500 cm

x = 175 cm

So, the third sphere must be placed at 175 cm from the first sphere.

Answer:

The student's average speed for the trip to school is 4 \(\frac{km}{h}\)

Explanation:

Speed ​​is a quantity that relates the displacement that an object makes in a given unit of time. In other words, speed is a physical quantity that expresses the relationship between the space traveled by an object, the time used for it and its direction.

Since the average speed relates the change in position to the time taken to effect said change, then:

\(speed=\frac{change in position}{time}\)

In this case, the student travels a total distance of 2 km between his home and school and the total time spent on the trip is 30 minutes, then:

Replacing:

\(speed=\frac{2 km}{0.5 hours}\)

Solving:

speed= 4\(\frac{km}{hours}\)

The student's average speed for the trip to school is 4 \(\frac{km}{h}\)

The buoyancy force on the boat in the water has a value of 107800 N.

The buoyant force on the boat in the water can be calculated using Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. In this case, the fluid is water, which has a density of 1000 kg/m³.

The buoyant force (Fb) can be calculated using the formula:
Fb = density of water × volume of water displaced × acceleration due to gravity
Fb = (1000 kg/m³) × (11 m³) × (9.8 m/s²)
Fb = 107800 N

Therefore, the buoyant force on the boat in the water is 107800 N.

--> water(H2O): this contains elements such as hydrogen and oxygen chemically bonded together

But substances such as sand is not a compound but a mixture which contains natural deposits of silicon dioxide, small rocks and other organic substances which are not chemically bond together.
