Answer:

the TWO SCALES are main SCALE and vernier scale

Explanation:

use the FORMULA ,length = main scale reading + 0.01multiply the no. of vernier scale coinciding with main scale.

5N ALONG - X axis.

It is the answer.

I HOPE it will HELP you.

ANSWER:

In order to be able to find DIFFERENT TYPES of conversions of the same PHYSICAL quantity in any two different systems of units , find the values of the quantity in the different systems.

Ex: In SI , the quantity - length is expressed as meter but in CGS , the unit for length is centimeter.

1 m = 100 cm

1 cm = 1/100 m

ANSWER:

The angular velocity is independent of the clock size,however for larger clocks the linear velocity of the pointers at the end of the hands will be greater.The second hand goes through 2 PIE RADIANS in 1 min.,or 2 pie radian/60 seconds,so w=pie/30 ran.s-1=0.03 rad .s-1.

Answer:The specific heat will be same as that of hot water.

EXPLANATION:

In substances after state change their specific heat changes as then they become another substance. MIND the word after. During state change latent heat comes into account. Cold water will give out that much amount of heat as the value of specific heat to REDUCE it's own temperature and APPROACH towards state change CONDITION.

Heat is the total energy of molecular MOTION in a SUBSTANCE while TEMPERATURE is a measure of the AVERAGE energy of molecular motion in a substance.

Answer:

displacement = √10 m

Explanation:

The girl walks 3 m east , then 4 m south and then 5 m vertically upward.

This means that she travels 1 m TOWARDS north along with the 4 m.

displacement is given by ,

AC² = 3²+1²

       =9+1

       =10

displacement = √10 m

Answer:

Law of conservation of momentum:

Initial momentum of ball A=ma ua

Final momentum of ball A=ma va

Force on A DUE to B=Rate of change of momentum ball A.

Finally it is saying that,

SUM of initial momentum=Sum of final momentum.

In this PROCESS momentum is conserved.

In a triangle, if the square of one SIDE is equal to the sum of square of other two sides then prove that the triangle is right angled triangle.

________________________

Given : AC² = AB² + BC²

To prove : ABC is a right angled triangle.

Construction : Draw a right angled triangle PQR such that, angle Q = 90°, AB = PQ, BC = QR.

Proof : In triangle PQR,

Angle Q = 90° ( by construction )

Also,

PR² = PQ² + QR² ( By using PYTHAGORAS theorem )...(1)

But,

AC² = AB² + BC² ( Given )

Also, AB = PQ and BC = QR ( by construction )

THEREFORE,

AC² = PQ²+ QR²....(2)

From EQ (1) and (2),

PR² = AC²

So, PR = AC

Now,

In ∆ABC and ∆PQR,

AB = PQ ( By construction )

BC = QR ( By construction )

AC = PR ( Proved above )

Hence,

∆ABC is congruent to ∆PQR by SSS criteria.

Therefore, Angle B = Angle Q ( By CPCT )

But,

Angle Q = 90° ( By construction )

Therefore,

Angle B = 90°

Thus, ABC is a right angled triangle with Angle B = 90°

ANSWER:

the answer is D as it is not STATIONARY

It is also compressible. The air PRESSURE outside the BALLOON is less than the air pressure INSIDE the balloon. ... When GASES escapes out, density of air inside the balloon reduces and it BECOMES like vacuum - no air. It collapses because the pressure of air outside is higher (atmosphere).

Answer:

In physics, rest is the state of an object being stationary relative to a particular frame of reference or another object.

Explanation:

example:In physics, rest is the state of an object being stationary relative to a particular frame of reference or another object; when the position of a body with respect to its surroundings does not change with time it is said to be "at rest". According to the theory of relativity, it is said that an object is "at rest relative to" another. For example, a train decelerates approaching a STATION and eventually comes to rest ALONGSIDE the platform. The train can be said to be "at rest with respect to the station", or, as the correct frame of reference is USUALLY implicit and/or provided by context, simply "at rest". In reality, there is nothing at absolute rest. For example, Earth's GRAVITATION constantly pulls objects toward its surface, while Earth is one of the objects the Sun constantly pulls towards itself, CAUSING it to orbit the Sun; the Sun, in turn, orbits the center of the Milky Way; and so on.

ANSWER:

IST law STATES that when we push any THING then the object will move.

Third law states that every action gives equal and opposite reaction

2nd law states that it is inversely proportional to the MASS of an object

Answer:

max ke = max Pe = m G h

h = r (1-cos 60) = r/2

so max (1/2) m v^2 = m g r/2

max v^2 = g r

T = m g + m v^2/r

T = m (g + g) = 2 m g = 2(.05)(10)

T = 1 Newton

Solution :

GIVEN, dv/dt = 18 + 10t

We know that v = velocity and t = TIME. Then the DIFFERENTIATION of v with RESPECT to time t is acceleration itself.

∴ acceleration = dv/dt = 18 + 10t

Answer:

Fundamental UNITS are the basic units , on the other hand Derived units are OBTAIN from fundamental units.

Explanation:

Fundamental units : The physical units which can neither be derived from ONE another , nor they can be further resolved into more simpler units are CALLED fundamental units. Ex- LENGTH , Mass , Time

Derived Units : All the physical units which can be expressed in terms of the fundamental units are called Derived units.

Answer:

WORKING of an AC Generator

Due to this, an emf is induced in the armature. This PRODUCES an electric current through the galvanometer and the slip RINGS and brushes. The galvanometer SWINGS between the positive and negative values. This indicates that there is an alternating current FLOWING through the galvanometer.

ANSWER:

no it is not the RIGHT way

Explanation:

Answer:

A DC generator is an electrical machine which CONVERTS mechanical energy into direct CURRENT electricity. This energy conversion is based on the principle of production of DYNAMICALLY induced emf.
