Answer:

On ADDING SALT, the external medium is made hypertonic, i.e., concentration of water is lowered as compared to the concentration of water inside the cell. Thus, water is released from the vegetables due to EXOSMOSIS (water MOLECULES goes out of the cell resulting i n shrinkage of cell). plz mark as BRAINLIEST

ANSWER:

it is KNOWN as short SIGHTEDNESS and its removal is wearing convex lens of SUITABLE power

Solution :-

As given

▪️Radius = 10 CM = 0.1 m

▪️No of rotation in 10 sec = 50

→ No of rotation in one sec = 5

→ FREQUENCY (f) = 5

▪️π = 3.142

**Frequency = rate of occurance of something over a given period of time

Now as we KNOW that :-

Angular VELOCITY (ω) = 2πf

So Angular velocity

= 2 × 3.142 × 5

= 10 × 3.142

= 31.42 rad/sec

Now also we know that

Linear velocity = Angular velocity × radius

v = ωr

So Linear velocity

→ v = 0.1 × 31.42

→ v = 3.142 m/s

So

The TOTAL resistance in the SERIES circuit is more than the greater one in the circuit. ... The potential difference across each resistance is the same and is EQUAL to the applied potential difference. 2. The total current through the parallel combination is the sum of the individual currents through the various RESISTORS.

Answer:

Picture shows the difference between the real depth and apparent depth of the OBJECT under water. We see the objects CLOSER than their real depth to the SURFACE. ... On the contrary FISH sees the objects away from their real distances. These are all results of the refraction of light.

ANSWER:

Jupiter is the largest planet in the SOLAR system, but it's Saturn—the solar system's second largest planet—that takes the prize for least dense. It's less dense than water, which has led many PEOPLE to POSTULATE that it would FLOAT

is this QUESTION is COMPLETED

Moment of Inertia and Angular MOMENTUM

Explanation:

13) Moment of inertia of solid SPHERE about diameter I = 0.4MR² where M is mass and R is RADIUS. SI unit of I is kgm².

14) Angular momentum of a body about an axis is defined as product of moment of inertia about the given axis and its angular velocity.

L = Iω

where I is the moment of Inertia and ω is the angular velocity. SI unit of L is kgm²/s

When BODY has LOW plateless that's why we feeled TIRE...

Given,

C 1 = 6 μ F

C 2 = 12 μ F

Potential Difference across C 1 = 2 V

let the potential Difference across C 2 be V volt.

As the two capacitors are connected in series , the CHARGE on each capacitor must be same.

∴ Charge on 6 μ F capacitor = Charge on 12μ F capacitor.

on putting the values,

6 F× 2 V = 12 F× V volt

on SOLVING,

We KNOW,

The emf ( E) is equal to the sum of potential difference across all the components of a circuit.

Battery voltage (E)  = V1 + V2

                                 = 2 V + 1V

                                 = 3 V

Answer:

0.5 m

Explanation:

the SPEED of TRAIN is 90km/hr = 25m/s

retardation = 5m/s²

using the equation v² - u2 = 2AS

5² - 0² = 2 ×25 s

25 = 50s

S = 1/2 ANS

Explanation:

Answer:

Materials that can be MAGNETIZED, which are also the ONES that are STRONGLY ATTRACTED to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements IRON, nickel and cobalt, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.which are used in magnets

ANSWER :-

〽DISTANCE :-

Formula to find the CIRCUMFERENCE : 2πr

(GIVEN 400 m as radius)

Distance TRAVEL is three fourth of the circumference .

△AOB is a right angle triangle.

By PYTHAGORAS theorem ,

(AB)^2=(AO)^2+(BO)^2

(AB)^2=400^2+400^2

(AB)^2=320000

AB=√320000

AB=565.68 metres

HOPE IT HELPS UHH #CHEERS

Answer:

The methods of charging up:⤵️⤵️⤵️

• Rubbing or friction .
• Contact or Conduction.
• Induction.

EXPLANATION:

☆ Charging by Rubbing or Friction ⬇️⬇️

▪ Different (insulator type) OBJECTS get charged by rubbing them against some other suitable object.

♤ Charging by Contact or Coduction⬇️⬇️

▪A given unchanged object is 'charged up' by bringing it in direct physical contact with another charged object. The charge (on the original charged object) then GETS 'shared ' between the two objects. Hence, the (originally) unchanged object also gets charged up.

♧ Charging by Induction ⬇️⬇️

▪ Bring a charged object near (but without touching it) the object to be charged. This would cause the charges in this (uncharged) object to get 'separated out'

▪ KEEPING the charged object in its nearby position, touch the uncharged object with the hand (if permitted; otherwise use a shielded metallic wire) to Connect it to the earth. Thus, the unchanged object is 'earthed'.

▪Still keeping the charged object in its position, remove the land (or the earth contact).

▪ Now remove the charged object from the neighbourhood of the object that was to be charged.

▪ The object would now be seen to have an electrical charge on it. The sign of this charge is opposite to the sign of the charge on the charged object used for making charging up.

Explanation:

manganin

___________

Answer: Generally alloys like CONSTANTAN or manganin are used as potentiometer wire because they posses high specific resistance and low TEMPERATURE COEFFICIENT.

Answer:

1:2.

Explanation:

R1=(RHO)L/A.

R2=(rho)2L/2A.

2 and 2 CANCEL each other.

R2=(rho)L/A.

Hence,

R1=R2.

In PARALLEL combination,

Total 1/R=1/R1 + 1/R2...........(1)

Since R1=R2,

R=R1/2.(KEEPING VALUE of R2=R1 in (1)).

Ratio R:R1=1:2.
