Answer:
d = 0.124 mm
Explanation:
It is given that,
Wavelength of light is 525 nm
It makes second maximum at an angle of 0.482 degrees
We need to find the separation of the slits.
For 2nd maximum, the equation for double slip experiment is given by :
[tex]d\sin\theta=n\lambda[/tex]
d = separation of the slits
[tex]d=\dfrac{n\lambda}{\sin\theta}\\\\d=\dfrac{2\times 525\times 10^{-9}}{\sin(0.482)}\\\\d=0.124\ mm[/tex]
So, the separation of the slits is 0.124 mm.
Answer: 0.124

Answer:
At Convergent Boundaries:
Subduction
Island arcs
Volcanic mountains
At Divergent Boundaries:
Mid-ocean ridges
Rift valleys
Plates pulling apart
Magma breaks through crust
Magma flows from cracks
Explanation:
A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.
Divergent boundaries occur in the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley.

Explanation:
Try to remember that sleep deprivation or the lack of sleep, messes with the amygdala in the brain - this is the part of the brain that controls some of our emotions. If you mess with the amygdala then it messes with you - it will cause you to be more fight than flight - it can make you hypersensitive to stuff that you normally could use your coping skills to conquer!

A 41 turn rectangular coil of dimensions 5.00 cm ✕ 10.0 cm is allowed to fall from a position where B = 0 to a new position where B = 0.520 T and the magnetic field is directed perpendicular to the plane of the coil. Calculate the magnitude of the average emf that is induced in the coil if the displacement occurs in 0.330 s.
Explanation:
We have,
Number of turns in a coil is 41
Dimensions of a rectangular coil is 5 cm by 10 cm
Initial magnetic field is 0 and new field is 0.52 T. The magnetic field is directed perpendicular to the plane of the coil.
It is required to find the magnitude of the average emf that is induced in the coil if the displacement occurs in 0.330 s. According to Faraday's law,
[tex]E=\dfrac{-d\phi}{dt}[/tex]
[tex]\phi[/tex] = magnetic flux
[tex]E=\dfrac{-d(NBA)}{dt}\\\\E=NA\dfrac{-(B_f-B_i)}{dt}\\\\E=41\times 0.005\times \dfrac{(0.52)}{0.33}\\E=0.32\ V[/tex]
So, the magnitude of induced emf is 0.32 V.
If the ammeter is 07 mA and the resistor is 56 ohms what is the voltage ?
So it’s a drawing of a circuit with the ammeter which says 07mA and a resistor of 56 with the Symbol got it
It says if you measured the voltage across the resistor in the circuit, you’d expect it to read?
Answer:
V = 0.0392 volt
Explanation:
given that the
Current I = 0.7 mA
Resistance R = 56 Ohms
According to Ohm's law,
V = IR
Where V is the Voltage in the circuit.
Substitute I and R into the formula
V = 0.7 ×10^-3 × 56
V = 0.0392 volt
The ammeter can be use to read current in a circuit when it is connected to the device in which the resistors are connected in series.
While for the Voltmeter, the resistors are connected in parallel.

If you apply a net force of 5N on a cart with a mass of 5 kg, show that the acceleration is 1 m/s2.
(SHOW WORK)
Answer: F = 5kg x 1 m/s2 = 5 N
Explanation:
Hi, to answer this question we have to apply the next formula:
Force (F) = mass x acceleration
Replacing with the values given and solving for F (force)
F = 5kg x 1 m/s2 = 5 kgm/s2
Since 1 Newton (N) = 1 kgm/s2
F = 5N

Pedro is planning to model how changes in weather affect evaporation from
lakes. For his first experiment, he wants to test how humidity affects the
evaporation rate. He places one beaker with 300 mL of water in a dry area,
and he places another beaker with 300 mL of water near a humidifier.
What is the dependent variable in Pedro's experiment?
A. Evaporation rate
B. Temperature
c. Humidity
D. Volume of water
Answer:
Evaporation rate is the dependent variable in Pedro's experiment
Explanation:
it is the variable that is being measured and is expected to change in response to changes in humidity. The independent variable is humidity, which is being manipulated by placing one beaker near a humidifier and the other in a dry area. Temperature and volume of water are not being directly manipulated in this experiment and are therefore not the dependent variable.
Hypothesis:
Part A
If we split a laser beam by using a diffraction grating slide, then we can
verify the _____________ by applying the formula λ = ds/l.
2) Part B If we split light into its individual wavelengths using a diffraction grating,
then we can determine the _____________ by multiplying the spacing of the
gradient lines (d) times the distance to the central maxima of the color band (s)
divided by the length distance from the grating slide to the screen (l).
Answer:
1.) Wavelength
2.) Number of fringes
Explanation:
1.) If we split a laser beam by using a diffraction grating slide, then we can
verify the wavelength by applying the formula λ = ds/l.
2) If we split light into its individual wavelengths using a diffraction grating,
then we can determine the number of fringes by multiplying the spacing of the gradient lines (d) times the distance to the central maxima of the color band (s) divided by the length distance from the grating slide to the screen (l).
39. Three 12 a resistors are connected in parallel and then connected to a 6.0 V battery. Find
the resulting current. Show your work. This is a two part question.
40. The devices and outlets in each circuit in a household are wired in parallel. The main
reason for this is
a. Plugging in more devices increases the total resistance on the circuit
b. Plugging in more devices decreases the total resistance on the circuit.
c. Unplugging a device does not affect the other devices on the circuit.
d. Connecting the devices in parallel is safer than if they were in series.
Answer:
39.) Current = 1.5 A
40.) B
Explanation:
Given that three 12 Ohms resistors are connected in parallel.
The equivalent resistance R will be
1/R = 1/R1 + 1/R2 + 1/R3
Substitute the values into the formula
1/R = 1/12 + 1/12 + 1/12
1/R = 3/12
Find the reciprocal of both sides
R = 12/3
R = 4 Ohms
From Ohm's law,
V = IR
Where V = 6v
Substitute V and the R into the formula and make current I the subject of formula
6 = I × 4
I = 6/4
I = 1.5 A
Therefore, the resulting current is 1.5 Ampere.
40.) If the devices and outlets in each circuit in a household are wired in parallel, The main reason for this is
Plugging in more devices decreases the total resistance on the circuit.
Because, the sum of resistance of resistors in parallel is less than the least resistance of a resistor is the circuit. Also, they will all share the same amount of voltage because there is no voltage drop.
