Explanation:

DILUTION is the process of decreasing the concentration of a solute in a solution, usually simply by mixing with more SOLVENT like adding more WATER to a solution. To DILUTE a solution means to ADD more solvent without the addition of more solute.

Electromagnet :: it is a ELECTRICALLY induced magnet , it is a core of magnetic material { such as iron}

surrounded by a coil of wire through which an electric current is passed .

it is stronger than a solenoid . also the poles can even be reversed , by reversing the flow of current. basically electromagnet is current FLOWING in a solenoid .

__________________________________________

Solenoid :: it is a cylindrical coil of wire acting as a magnet when carrying an electric current . it is a soft iron core . diameter is small as compared to length . when an electric current flows through a solenoid it generates magnetic field similar to that of Bar magnet. it is basically a single wire wrapped to a coil.

ANSWER: E field (NET) = 4.8 × 10^12 N/M

Direction = TAN inv(3/4) from y axis

Explanation:

Explanation:

Distance is basically the area under (v-t) curve ..so here uu have to take area of triangle for distance

and for accelaration use 1st eq'n motion ..i.e. at t=0 , u=40m/s and at t=10sec , v=0

v = u + at

0 = 40 + a(10)

-40 = a(10)

a = -4m/sec^2

negative sign shows that the object is not accelarating , it is deaccelarate at the rate of (4m/s per sec)...

Let the CAPACITANCES be C₁ and C₂

Effective CAPACITANCE in :

Series = C₁C₂/(C₁ + C₂)

PARALLEL = C₁ + C₂

By the GIVEN conditions,

C₁ + C₂ = 4C₁C₂/(C₁ + C₂)

(C₁ + C₂)(C₁ + C₂) = 4C₁C₂

C₁² + C₂² + 2C₁C₂ = 4C₁C₂

C₁² + C₂² - 2C₁C₂ = 0

(C₁ - C₂)² = 0

C₁ - C₂ = 0

C₁ = C₂

Hence the given conditions occur only if both the capacitances are equal

Answer:

Thrust and Pressure

Have you ever wondered why a camel can run in a desert EASILY? Why an ARMY tank weighing more than a thousand tonne rests upon a continuous chain? Why a truck or a motorbus has much wider tyres? Why cutting tools have sharp edges? In order to address these questions and understand the phenomena involved, it helps to INTRODUCE the concepts of the net force in a particular direction (thrust) and the force per unit area (pressure) acting on the object concerned.

Let us try to understand the meanings of thrust and pressure by considering the following situations:

Situation 1  :

You stand on loose sand. Your feet go deep into the sand. Now, lie down on the sand. You will find that your body will not go that deep in the sand. In both cases the force exerted on the sand is the weight of your body.

You have learnt that weight is the force acting vertically downwards. Here the force is acting perpendicular to the surface of the sand. The force acting on an object perpendicular to the surface is called thrust.

When you stand on loose sand, the force, that is, the weight of your body is acting on an area equal to area of your feet. When you lie down, the same force acts on an area equal to the contact area of your whole body, which is larger than the area of your feet. Thus, the effects of forces of the same magnitude on different areas are different. In the above cases, thrust is the same. But effects are different. Therefore the effect of thrust depends on the area on which it acts.

The effect of thrust on sand is larger while standing than while LYING. The thrust on unit area is called pressure. Thus,

    Pressure =thrust/area

Substituting the SI unit of thrust and area in the above formulae, we get the SI unit of pressure as

                                                                                                          N/m2 or N m–2.

In honour of scientist , Blaise Pascal, the SI unit of pressure is called pascal, DENOTED as Pa.

Answer:

120 KJ

Explanation:

H = I²RT

H= 4*100*(300) [5 minutes is 300 seconds]

H= 120000 J

H= 120 KJ

Given :

• Resistance of wire =5 Ω
• Potential difference =7 V
• TIME ,t =20min=1200sec

To Find :

Heat produced in a wire

Solution :

We have to find heat produced in a wire .

According to the JOULE's LAW of Heating

The heat produced in a wire is directly proportional to:

• Square of current
• Resistance of wire
• time (t) , for which current is passed.

We KNOW that,Ohm's law :

Now put the given values

We know that

1J = 0.239 Calorie

⇒11,760 JOULES = 2810.7 Calories( aprrox)

Therefore, Heat produced in a wire is 2810 calories .

<P>Heat is a form of energy

Energy = POWER * Time

Since, P = VI

Therefore, H = (VI) t

Now look at the IMAGES for CLEAR UNDERSTANDING. So the effective RESISTANCE is 6/11 ohms. PRACTICE some more questions following the steps and you will enjoy solving them.

That's a LONG WAY up!

Answer:

The displacement is 5m.

Explanation:

Given:

To the east = 4 m

To the SOUTH = 3 m

To find :

The displacement

Solution :

Displacement is the shortest distance travelled from the INITIAL point to the final point.

Distance to east (x) = 4 m

Distance to the south (y) = 3 m

Displacement =

★

⇒ s =

⇒ s =

⇒ s =

⇒ s = 5

Displacement = 5 m

THEREFORE, the displacement is 5m.

ANSWER:

EXPLANATION:

DENSITY = mass/volume

% density = (0.1/10   +   3*0.5/20)*100

                     =   (0.01  +  0.075)*100

                     =  8.5%

Answer:

Total DISPLACEMENT : 179.3 Km

Average Velocity : 69.4 m/s

Explanation:

A.T.Q.

Let B be the place at which he stopped

Velocity from A to B, v1 : 85 km/h

Time TAKEN,

From A to B, T1 : 35 min = 0.58 hr

From B to C, t2 : 2 hr

Displacement,

From A to B, s1 : v1 x t1 = (85 x 0.58) Km = 49.3 Km

From B to C, s2 : 130 Km

Total Time taken : t1 + t2 = 0.58 + 2 = 2.58 hr

Now, Total Displacement : s1 + s2

= 49.3 + 130 Km

= 179.3 Km

Also, Average Velocity : Total Displacement/Total Time Taken

= (s1 + s2)/(t1 + t2)

= 179.3/2.58

= 69.4 m/s
