Explanation:

When we TAKE the electric flux of SURFACE all we need is the total charge INSIDE the surface as given in the equation.

where,

is the electric flux

is the total charge inside the surface (Gaussian surface)

is the PERMITIVITY of the medium

ANSWER:

By USING KIRCHOFFS LAW

T=2π√l/g

ΔT/T=1/2Δl/l + 1/2Δg/g

ΔT/T*100=1/2*Δl/l*100 + 1/2*Δg/g*100

ΔT/T*100=4/2+2/2

=2+1

=3%

Answer:

Steel is a mixture of several METALS (this is called an alloy) but most of it is iron. Steel is harder and stronger than iron. Steels are often iron alloys with between 0.02% and 1.7% percent carbon by WEIGHT. Alloys with more carbon than this are known as CAST iron. Steel is different from WROUGHT iron, that has little or no carbon. There are some NEWER steels in which carbon is replaced with other alloyingmaterials.

AMMETER and GALVANOMETER for SMALL READING

Answer:-

Angular MOMENTUM is the product of moment of inertia and angular velocity, if the angular momentum remains CONSTANT (is conserved), then the angular velocity (rotational speed) MUST INCREASE.

Answer:

when the PRESSURE OUTSIDE the CONTAINER is more ,the pressure INSIDE will decrease ..this will happen when CHANGED to vise versa

Answer:-

The CURRENT is directly PROPORTIONAL to the VOLTAGE and inversely proportional to the resistance.

V = iR

ANSWER:

3×10⁵ km/s

Explanation:

Simply COVERT meters into KILOMETERS since the time is in the same units.

Answer:

Heya Faisal here's ur answer

Potential energy is the energy by virtue of an object's position RELATIVE to other objects. Potential energy is often associated with restoring forces such as a spring or the force of GRAVITY. ... This WORK is stored in the force field, which is said to be stored as potential energy.

Hope it helps you...

Answer:

The POINT is that pi radians is EQUAL to 180 DEGREES. Radians are a UNIT of measurement for angles, just like degrees are, and pi is just the number of radians that makes up that angle. Just as one radian is equal to 57.3 degrees (approximately)

Answer:

see if there are any parrellel or SERIES connection in the CIRCUIT

EXPLANATION:

Hey MATE...

The answer to your question is

An ammeter is connected in SERIES with the circuit because the purpose of the ammeter is to measure the current through the circuits. The ammeter is a low impedance device connecting it in parallel with the circuit would CAUSE a short circuit hence , DAMAGING the ammeter and/or the circuit

Hope it HELPS you.....

ANSWER ☺️

The science BRANCH or PRACTICE of farming, INCLUDING cultivation of the soil for the growing crops is called Agriculture.

HOPE it HELPS ✔️

we KNOW that

this shows that if PRESSURE is inversly proportional to the area

this means that if area is increased, then pressure will AUTOMATICALLY decrease

now, on a bed, area is more, i.e., we COVER a larger area while we sit on bed; as compared to other places, therefore pressure applied is less, and thus we comfortably sit on a bed

Answer:

FOCAL length is 0.07m or 3/40 m

Explanation:

MAGNIFICATION,m = 3

Object - distance, U = -10cm=-0.1 m

Let the image of object be v m

m = - v/u

3 = v/0.1

v = 0.3 m

1/v+1/u=1/f [here f is focal length]

1\0.3+1/0.1=1/f

1/f =40/3

f = 0.07 m

ANSWER:-

Electric energy converted into rotational KINETIC energy of the CENTRAL axis.

what is WRONG with you

Explanation:

Focal LENGTH (f)=10cm

Object distance (u)=15cm.

Height of the object=6cm.

Using the mirror's formula,

1/f=1/v+1/u

1/-10=1/v+1/-15

1/v=1/-10+1/15

1/v=(-3+2)/30

v=-30cm

Since, IMAGE distance is negative, therefore,it is real and inverted.

Now, magnitude=-v/u

=-(-30)/15

=2

Since, magnitude in greater than

1, therefore image is MAGNIFIED

Also,m=H of image/H of object.

2=H of image/6

Height of image =12cm.

characteristics of image are

Real, inverted and Magnified.

ANSWER:

RATE of change in a BODY is CALLED acceleration and when gravitational force helps in CHANGING the momentum of the body thn it's known as acceleration due to gravity

velocity = ds/dt

ds/dt = 8 - 20t

v at (t = 2 ) = 8 - 20 × 2 = -32 m/s

HOPE it helps

it is used to measure POTENTIAL DIFFERENCES across two points

the circuit will BREAK if more CURRENT is passed

uniform circular motion is accelerated because the VELOCITY ,changes DUE to continuous CHARGE in the direction of motion. So, even when the body moves to a constant speed, its velocity is not constant.

ANSWER:

EXPLANATION:

Here's your answer in the PIC

• SPEED is the DISTANCE traveled per unit of time. It is how fast an object is MOVING.
• Speed is the scalar QUANTITY that is the magnitude of the velocity VECTOR.
• Higher speed means an object is moving faster.
• Lower speed means it is moving slower.

EXPLANATION:

u=18km/hr=5m/s

a=5m/s²

s=200m

2as=v²-u²

2as=v²-(5)²

2*5*200=v²-25

v²=2025

v=45m/s

Given:

f=at

Where a is constant and time is t

f= dV/dt=at

Integrate on both sides.

Limits of VELOCITY:

INITIAL velocity =u

Final velocity=V

Time initial=0

Final time=t

On INTEGRATING:

dV/dt=at

We get

V-u= 1/2 at^2

V=u+1/2at^2

Now on sq

V=u+at^4/4

Answer:

Displacement-TIME graph. The gradient of a displacement-time graph at a particular time GIVES the velocity of the object at that time.

Explanation:

Distance-time graphs. If an object moves along a straight LINE, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is MOVING.

The UNIT of ACCELERATION is m/s^2

Answer:

The mass number is TYPICALLY found at the top. (You might see it at the bottom in the PERIODIC table) and the atomic number at the bottom.

Atomic number/number of PROTONS = 11

Mass number/sum of protons and neutrons = 23

Number of neutrons = 23-11= 12

Number of electrons = 11 (since the sodium ATOM is NEUTRAL)

Explanation:

Like this you can find number of electron

Explanation:

If I get your question correctly, you're asking for a trend in the change of the Young's modulus of substances with changes in temperature. Kindly do correct me if I'm wrong here.

The answer is… you cannot have a fixed, unchanging trend. It all depends. The other guy who answered said that Young's modulus will decrease with decrease in temperature for most substances. I think he probably wanted to say that the Young's modulus would increase with the decrease in temperature for metallic bonded solids, because decrement in temperature should decrease the space between the constituent particles, thus increasing the interaction energy and also making the substance stiffer than it was previously.

Consider the case of a thermosetting plastic. You HEAT it up the first time, it gets stiff because of development of CROSS linkages. Now you cool it down to the same temperature it was at INITIALLY, it's still a lot stiffer than earlier because you can't get rid of the cross linkages.

Heat up a wet brick in a kiln and then cool it down again. Silicates cross link to make a very hard structure. It's still hard.

There goes the very idea of a trend in the change in Young's modulus.

I would say that your question could've been a better one had you specifically asked for a certain kind of substance, such as metals, MAYBE? Anyhow… not for me to judge.

If you meant metals, though, I believe you've got your answer.

If you wanted to know about the relationship between the Young's modulus and the coefficient of thermal expansion, (that's a VERY good question by the WAY), I suggest you make a thermodynamical analysis of a simple situation(which I trust you can do quite easily). You should end up with an inverse relationship in case of a simple metallic solid.

In a TRANSVERSE wave, the particles are displaced perpendicular to the direction the wave travels. EXAMPLES of transverse waves include vibrations on a string and ripples on the surface of water. ... An example of longitudinal waves is compressions MOVING ALONG a slinky.
