In frame C, the magnetic FIELD at the center of the frame will not be zero.

Explanation:

As per the given FIGURES, only figure C will not have zero magnetic FIELDS at the center because of the flow of the current in the same direction with uniform magnitude ALONG with the approaching and outgoing current.

The options (A) and (B) are incorrect because the current line flows through the center which implies that the perpendicular distance from the center would be zero due to approaching and outgoing currents through the center.

The last OPTION i.e. option D is wrong because the current approaching and the current outgoing would be equal because of the magnetic field and thus, it will be zero.

Hence, option C is the correct answer.

Explanation:

Surface TENSION is the to FORCE per unit length. That MEANS formula for surface tension is = force/length . As we know that the DIMENSIONAL formula for length is L . And that for force is MLT^-2.

ANSWER:

A COMMENSAL is the CORRECT answer

Answer:

Continuity principle, or continuity equation, Principle of FLUID MECHANICS. Stated simply, what flows into a defined volume in a defined time, minus what flows out of that volume in that time, MUST accumulate in that volume. If the sign of the accumulation is negative, then the material in that volume is being depleted.

ANSWER:

INSTANTANEOUS ACCELERATION = d²x/dt²

ANSWER:

Given:

Pendulum is taken to height half of the radius of Earth

To find:

% Change in time PERIOD of pendulum

Calculation:

FIRST Calculate the new gravitational acceleration :

height be h , radius be r , g be gravity at surface

Putting h = r/2

Now, Initial time period of Pendulum :

Final time period:

So change in time period :

So percentage change :

So there is 50% increase in Time period.

ANSWER:

SPEED × TIME = distance

Explanation:

330×2.5 =825 m

ANSWER:

CENTRIPETAL acceleration

Centripetal acceleration is the acceleration experienced while in uniform CIRCULAR motion. It always points toward the center of ROTATION.

Answer:

so FREQ of C is either 340+6 or 340-6

but as per question when MASS of D is made LESSER then beat frequency reduces from 6 to 4

so frequency of C is 340-6=334

TIME, t = 4 sec

Final VELOCITY, V = 0 m/s

Acceleration, a = -9.8 m/s²

v = u + at

0 = u - 9.8(4)

u = 39.2 m/s

v² - u² = 2as

0 - (39.2)² = 2(-9.8)s

s = (39.2)²/19.6

s = 78.4 m

Answer:

Question:

Tuning fork A produces 4 beats with tuning fork B of frequency 346 Hz. When tuning fork A is FILED, the NUMBER of beats heard is 6 per SEC. Find original frequency of Tuning fork A.

Given:

Beat frequency = 4 Hz.

Frequency of B = 346 Hz.

If Tuning fork A is filed, then beat frequency becomes 6

To find:

Frequency of Tuning fork A.

Concept:

We don't know if frequency of Tuning fork A is greater or lesser than that of Tuning Fork B

So, either of the 2 Equations can form :

Now , we know that if a tuning fork is filed, then it's frequency increases .

This is possible only in Equation (1)

So taking Equation (1) in consideration:

So final answer is 350 Hz.

ANSWER:the original frequency of B is 325 HZ as GIVEN below the question.

EXPLANATION:

As the freezing mixture cold water in the central portion of the cylinder, water contracts and its density increases. Consequently the cold water sinks to the bottom and warm water from the bottom Rises up to TAKE its place does by conduction, water of the LOWER part cools .

answer : option (2) 0.42 × 10³ J/Kg/K

The specific heat capacity of copper, S = 0.1 cal/g/°C

we have to find it in J/Kg/K

we KNOW, 1 cal = 4.2 joule

1000g = 1 kg

change in degree CELSIUS = change in Kelvin

so, °C = K

now 0.1 cal/g/°C = 0.1 (4.2 J)/(10^-3 Kg)/K

= 0.1 × 4.2 × 10³/ J/Kg/K

= 0.42 × 10³ J/Kg/K

An AC or a refrigerator does some work to move heat from the cold reservoir/sink to the HOT reservoir or source . So if you want to COOL a ROOM by opening a refrigerator then the room cannot be cooled because the cold reservoir is the refrigerator and the hot reservoir is the room , then the heat from the refrigerator is expelled back to the room but you can cool a room with an AC as the sink here is the room and the source is the outside environment .
Efficiency is DENOTED by β
β = heat expelled / amount of work done

OK BRO THANKS dyubjjv

Explanation:

ANSWER:

Explanation:

Part (a): The wave's amplitude, wavelength, and frequency can be determined from the EQUATION of the wave:

y(x,t) = (0.9 cm) sin[(1.2 m-1)x - (5.0 s-1)t]

The amplitude is whatever is multiplying the sine.

A = 0.9 cm

The wavenumber k is whatever is multiplying the x:

k = 1.2 m-1

The wavelength is l =  

2p

k

= 5.2 m

The angular frequency w is whatever is multiplying the t.

w = 5.0 rad/s

f =  

w

2p

= 0.80 Hz

Part (b): The wave speed can be found from the frequency and wavelength:

v = f l = 0.80 * 5.2 = 4.17 m/s

Part (c): With m = 0.012 kg/m and the wave speed given by:

v = (  

T

m

) ½

This gives a tension of T = m v2 = 0.012 (4.17)2 = 0.21 N.

Part (d): To find the direction of propogation of the wave, just look at the sign between the x and t terms in the equation. In our case we have a MINUS sign:

y(x,t) = (0.9 cm) sin[(1.2 m-1)x - (5.0 s-1)t]

A negative sign means the wave is traveling in the +x direction.

A POSITIVE sign means the wave is traveling in the -x direction.

Part (e): To determine the maximum transverse speed of the string, remember that all parts of the string are experiencing simple harmonic motion. We showed that in SHM the maximum speed is:

vmax = Aw

In this case we have A = 0.9 cm and w = 5.0 rad/s, so:

vmax = 0.9 * 5.0 = 4.5 cm/s

The materials that allow for free flow of electric charge through them are called conductors. The conducers have very SMALL values of resistivity. They give no or very slight RESISTANCE to ELECTRICITY flow.

The METALS are very strong electric charge conductors. GOLD, copper and even aluminum are amongst the best electricity conductors. Our skin also acts as an electrical conductor.

Graphite is just non-metal, and is an electricity conductor.

Both metals, steel, and graphite have free electrons that can pass through the conductor freely. These free electrons make strong electricity conductors for metals, alloys and graphite.

ANSWER:

We KNOW that v^2 - u^2 = 2as

Here, u = 10 m/s , a = -10 ms^-2 , v = 0 m/s

0 = 10^2 + 2 × -10 s

0 = 100 -20s

20s = 100

s = 5 m

Explanation:

Mathematically, expression of density is given by two scalar TERMS i.e mass and volume. So there is no WAY that it can be a VECTOR or a TENSOR of ORDER greater than zero. Intuitively, density is scalar as it does not posses any direction.

Given that :

• Area between plates (A) = 2 sq. metre

• Charge on plates

We know that ,

REQUIRED force between them is 1.048 N

Wein's displacement LAW states that the wavelengenth of the maximum energy at one specific temperature is inversely proportional to the temperature.


● The "DISPACEMENT" term is here because while plotting the graph of the temperature, wavelength and Energy the wavelength of higher energy at lower temperature starts to shift (displace) TOWARDS the left SIDE as the temperature increases.
