Write a hypothesis based on observations and scientific principles.

Answers

Answer:

An example of a hypothesis based on observation and scientific principles is:

Deaf children whose parents are deaf will acquire language faster than deaf children whose parents are not deaf.

A hypothesis is an informed prediction or a tentative statement about what you think that would occur in a scientific experiment as a result of experience from observations accepted by scientific rules and law.

A hypothesis is a testable statement obtained from the research question but questions cannot be tested directly, it is the proposed relationship between the variables that are tested.

An example of a hypothesis is:

Deaf children whose parents are deaf will acquire language faster than deaf children whose parents are not deaf.

This specifies the direction of the hypothesis because one group is faster than the other.

In a diffraction experiment, a laser beam incident on a single slit of width a = 0.02
mm produces a diffraction pattern on a screen 100 cm from the slit. The width of the
central maximum is 2.8 cm. What is the wavelength of the light?

Answers

The n-th place is 2×10 −4 m

The diffraction pattern's minima is

nDλ =(3−1) d

Dλ = d

2Dλ

​ d= x 3 −x

​ 2Dλ = 3×10 −3

2×0.50×6000×10 −10

=2×10 −4 m

Why do diffraction patterns occur?

Diffraction of light, as it is used to describe light, occurs more explicitly when a light wave passes by a corner or via an aperture or slit that is physically

Light is diffracted primarily as a function of wavelength (frequency), amplitude, and slit width. The incident waves must have a larger amplitude than the slit width for any diffraction to take place. Diffraction won't happen if the wave is less than the slit width.

The quantity of diffraction increases with the wave's wavelength. When the gap size is almost equal to the wavelength, the most 2×10 −4 m occurs.

Answers

Answer:

(a) 180 km

(b) 30km

Explanation:

To find displacement (in this case, kilometers) you need to convert km/h to km, this can be done by multiplying by the amount of hours:

[tex]\frac{60km}{h}*3h=60km*3=180km \\\frac{60km}{h} *h/2 = 60km/2=30km[/tex]

(The h/2 term came from 1/2*h, since half an hour is h*1/2)

Solenoid A has length L and N turns, solenoid B has length 2 L and N turns, and solenoid C has length L / 2 and 2 N turns. If each solenoid carries the same current, rank the magnitudes of the magnetic fields in the centers of the solenoids from largest to smallest.

Answers

Rank of the magnitude of the magnetic fields in the centers of the solenoid from largest to smallest is,

[tex]B_{C}\; > B_{A}\; > B_{B}[/tex]

We know that, Magnetic field is directly proportional to Turns (N) and inversely proportional to Length (L) of the solenoid.

[tex]B \propto\frac{N}{L}\;\;\;\;\;------ equation(1)[/tex]

For Solenoid A,

[tex]Length\;(L) = L[/tex]

[tex]Turns\;(N)=N[/tex]

Substitute the value of turns and length in equation(1),

[tex]B_{A} =\frac{N}{L}[/tex]

For Solenoid B,

[tex]Length\;(L) = 2\;L[/tex]

[tex]Turns\;(N)=N[/tex]

Substitute the value of turns and length in equation(1),

[tex]B_{B} =\frac{N}{2L}[/tex]

[tex]B_{A} =\frac{1}{2}\;\frac{N}{L}[/tex]

For Solenoid C,

[tex]Length\;(L) = \frac{L}{2}[/tex]

[tex]Turns\;(N)=2N[/tex]

Substitute the value of turns and length in equation(1),

[tex]B_{C} =\frac{2N}{\frac{L}{2} }[/tex]

Describe the magnetic field?

The magnetic influence on moving electric charges, electric currents and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field. The magnetic field of a permanent magnet pulls on ferromagnetic substances like iron and attracts or repels other magnets. A magnetic field that varies with location will also exert a force on a variety of non-magnetic materials by changing the velocity of those particles' outer electrons.

Safety belts protect people in cars in the event of an accident because, according to Newton’s laws of motion, when an impact causes the car to suddenly change its motion -

A.the speed of the people always increases, since now they have not one but two forces acting on them.
B.the speed of the car always increases, giving it greater force since the mass will remain the same.
C.the car now has a greater overall mass - its own mass plus the mass of the object by which it has been struck.
D.the people in the car will continue to move in the same direction and at the same speed as before the impact.

Answers

Answer:

D :)

Explanation:

When an impact causes the car to suddenly change its motion, (D) the people in the car will continue to move in the same direction and at the same speed as before the impact.

What is Newton's first law of motion?

Newton's first law of motion states that Unless influenced by an imbalanced force, a body at rest stays at rest, and a body in motion keeps moving in a straight path at a constant pace. This law is commonly known as law of inertia and the resistance of a body to maintain its state of rest is called inertia of rest, same as, the resistance of a body to maintain its state of motion is called inertia of motion.

When a car is moving with certain speed, the car along with the people inside the car is in inertia of motion. In an event of accident, the car comes in rest in no time but the man in the car is still in inertia of motion. So, his body moves forward in the car which may cause injuries. To prevent such injuries, the people inside a car are advised to use safety belts.

So, correct answer  is option (D).

What does a step down transformer change in an alternating current

Answers

The step down transformer decrease the incoming current's voltage.

Transformers go with the principle of mutual inductance . A changing magnetic field in one circle of wire actuates an electromotive force (EMF) in an adjoining circle of wire, inductively coupled to the primary. In exceptionally fundamental terms, a transformer comprises two coils of wire with tall shared inductance. These coils are electrically isolated whereas they share a common magnetic circuit. In a step-down transformer, there is a decrease in the incoming current’s voltage, where the primary voltage is the incoming voltage whereas the outgoing voltage is considered the secondary. the second coil has fewer windings than the primary, permitting a decrease in voltage within the exiting electrical stream. The primary winding, which is the primary set of coils, interfaces to an alternating-current voltage source, or primary voltage influx. The secondary coil interfaces to the stack, or secondary voltage outpouring, conveying the electrical control absent from the transformer. The substituting current streaming in at the primary voltage makes a substituting magnetic flux. This actuates a similar current within the secondary coil, making a secondary voltage. Here, the diminished number of windings within the secondary coil successfully diminishes the resultant voltage, subsequently “stepping down” the voltage to a lower value whereas keeping up a steady frequency.

a car initially traveling at 60 km/h accelerates at a constant rate of 2.0 m/s2. how much time is required for the car to reach a speed of 90 km/h? quizlet

Answers

Time required for the car to reach a speed of 90 km/h is 4.165 seconds.

To solve for time, use the formula for time, t = d/s which means time equals distance divided by speed.4.165 sec

In light of the posed query,

Initial velocity is 60 km/h, which is 60 x 1000 / 36600, or 16.67 m/s.

90 km/h is equal to 901000/3600, or 25.

2 m/s2 for acceleration, or a.

t = time

We are also asked to determine how long it will take the car to

accelerate to its final speed of 90 km/h.

We are aware,

v = u+at

Given the values we receive,

25 = 16.67 + 2t

2t = 25-16.67

2t = 8.33

t = 8.33/2

t = 4.165 sec

Thus, the car will take 4.165 sec to attain the final velocity of 90 km/h if its acceleration is 2 m/s^2 and initial velocity is of 60 km/h.
