Determine the Vo in the
circuit of the following
figure :​

Given :

Solenoid 2 has twice the radius and six times the number of turns per unit length as solenoid 1.

To Find :

The ratio of the magnetic field in the interior of 2 to that in the interior of 1.

Solution :

We know, magnetic field in the interior of a solenoid is given by :

[tex]B = \dfrac{\mu ni}{L}[/tex]

Let, length of solenoid 2 is L.

Therefore, length of solenoid 1 is 6L.

[tex]B_a=\dfrac{\mu (6n)i}{L}\\\\B_b = \dfrac{\mu n i}{L}[/tex]

Dividing [tex]B_a[/tex] by [tex]B_b[/tex] :

[tex]\dfrac{B_a}{B_b}=\dfrac{\dfrac{\mu (6n)i}{L}}{\dfrac{\mu n i}{L}}\\\\\dfrac{B_a}{B_b}=6[/tex]

Therefore, the correct answer is C. 6.

Answer:

i found: μk= 0.25

Explanation:

Newton's law is split into two components along

x and y , that, using our data, give:

30 − μkRn = 0

Rn = mg = 12⋅9.81 = 117.7 ≈ 118N

So: μk = 30/118 = 0.25

The assertion that ocean waves move on the water's surface is accurate. Therefore, choice A is right.

A wind wave, water wave, or tornado water wave is a surface wave that develops on a body of water's free surface as a result of the air flowing over the ocean's surface. The fetch is the distance at which two objects come into touch when facing the wind.

The wind is the most frequent source of waves. The friction between the wind and the surface of the water produces wind-driven waves, also known as surface waves. A wave crest is produced when wind continuously disturbs the water's surface in an ocean or lake.

The statements about ocean waves a true will be they travel on the surface of the water.

Thus, option A is correct.

Elastic Energy - Mechanical Energy

Answer:

Apparent depth = 45 cm

Explanation:

The refractive index of water in a pool, n = 4/3

Real depth, d = 60 cm

We need to find its apparent  depth when viewed vertically through  air.​ The ratio of real depth to the apparent depth is equal to the refractive index of the material. Let the apparent depth is d'. So,

[tex]n=\dfrac{d}{d'}\\\\d'=\dfrac{d}{n}\\\\d'=\dfrac{60}{\dfrac{4}{3}}\\\\d'=45\ cm[/tex]

So, the apparent depth is 45 cm.

Answer:

K = ρL²g

Explanation:

Consider L as the length of the raft inside the water when the raft is displaced through additional distance y;

Then:

F = upthrust ( restoring force) = weight of the liquid displaced.

[tex]F = V_{\omega} \rho_{\omega} g= A y \rho_{\omega} g[/tex]

Answer:

b)The new centripetal force is 9 times more

Explanation:

The formula to apply in this case is that of tension force on a spring which is equal to the centripetal force.

T= mv²/r --------i

where T is the tension on the spring

v= velocity/speed of the ball = 7.33 m/s

m= mass of the ball , 0.015 kg

r= radius of circle , 0.70 m

Use the values in the formula as;

T= {0.015 * 7.33² } / 0.70

T= 0.8059335 / 0.70

T= 1.15 N ---------i

If the speed is tripled then;

v= 21.99 m/s

T= 0.015 * 21.99² / 0.70

T= 10.36 N ------ii

Check the changes by dividing i and ii as ;

10.36 / 1.15 =  9.01

This is 9 times more hence if the speed is tripled ,the new centripetal force is 9 times more.

If there were no static friction between the soles of your shoes and the ground, then you could move your feet back and forth but your body would never go anywhere.

Same for using tires to move a car, a bus, a bicycle or a motorcycle.

Answer:

What about it?

Explanation:

Answer:

0 m/s.

Explanation:

When an object is shot up into the air the only force acting on it is gravity while neglecting wind. As the gravity is acting on the object it keeps decelerating till its velocity becomes 0 after which it can go no further. The maximum height of the object is at this point.

So, at its maximum height the velocity of the puck will be zero.

Answer: Spray bottles are an extremely useful type of machine and an excellent demonstration of basic plumbing principles. A spray-bottle head is made up of only a few parts. It has a trigger lever, which activates a small pump. This pump is attached to a plastic tube that draws cleaning fluid from the bottom of the reservoir. The pump forces this liquid down a narrow barrel and out a small hole at the gun's muzzle. The hole, or nozzle, serves to focus the flowing liquid so that it forms a concentrated stream.

The only complex element in this design is the fluid pump, and it's about as simple as they come. The main moving element is a piston, housed inside a cylinder. Inside the cylinder, there is a small spring. To operate the pump, you pull the trigger back, pushing the piston into the cylinder. The moving piston compresses the spring, so when you release the trigger, the piston is pushed back out of the cylinder. These two strokes of the piston, into the cylinder and out again, constitute the entire pump cycle.

Mass = 425 kg

distance = 614.4 m

acceleration = 1.8 m/s²

Answer :

Count Force first.

[tex]f \: = m \: \times a[/tex]

F = 425 × 1,8

F = 765 N ✅

Now let's count Work.

W = 470016 J ✅

Answer:

The final components of velocity of the composite object is 3.33 m/s.

Explanation:

Given;

mass of the first object, m₁ = 3.35 kg

initial velocity of the first object, u₁ = 4.90 m/s in positive x-direction

mass of the second object, m₂ = 1.88 kg

initial velocity of the second object, u₂ = 3.12 m/s in negative y-direction

initial momentum of the first object, P₁ = 3.35 x 4.9 = 16.415 kgm/s

initial momentum of the second object, P₂ = 1.88 x 3.12 = 5.8656 kgm/s

The resultant velocity of the two objects is given by;

R² = 16.415² + 5.8656²

R² = 303.858

R = √303.858

R = 17.432 kgm/s

Apply the principle of conservation of linear momentum for inelastic collision;

total initial momentum before = total final momentum after collision

P₁(x) + P₂(y) = Pf

R = Pf

R = v(m₁ + m₂)

17.432 = v(m₁ + m₂)

where;

v is the final components of velocity of the composite object

[tex]v = \frac{17.432}{m_1 + m_2} \\\\v = \frac{17.432}{3.35+1.88} \\\\v = 3.33 \ m/s[/tex]

Therefore, the final components of velocity of the composite object is 3.33 m/s.

Answer:

1 m/s²

Explanation:

The following data data were obtained from the question:

Net force (F) = 10 N

Initial mass (m1) = 5 Kg

Initial acceleration (a1) = 2 m/s²

Final mass (m2) = double the initial mass = 2 × 5 = 10 kg

Final acceleration (a2) =?

The final acceleration of the object can be obtained as follow:

Recall:

Force (F) = mass (m) × acceleration (a)

F = m × a

Keeping the force constant, we have

m1a1 = m2a2

With the above formula, we can obtain the final acceleration of the car as follow:

Initial mass (m1) = 5 Kg

Initial acceleration (a1) = 2 m/s²

Final mass (m2) = 10 kg

Final acceleration (a2) =?

m1a1 = m2a2

5 × 2 = 10 × a2

10 = 10 × a2

Divide both side by 10

a2 = 10 /10

a2 = 1 m/s²

Therefore, the final acceleration of the car will be 1 m/s²
