ong>Answer:

WATER has a very LARGE heat capacity, so it takes a lot of energy to change the temperature. Warmer water will be less dense and move upward to the top of the test TUBE to BOIL while the colder water can stay at the bottom. Water does not conduct heat through it very MUCH and ice conducts the heat through much less.

ong>ANSWER:

Marathi is TAUGHT US by mr.javed

ong>ANSWER:

Given,

Force (F) = 2N

Displacement (d) = 2.5 m

Work Done = Fd

= (2*2.5) J

= 5J

I hope this HELPS.

ong>Explanation:

Potential energy, stored energy that depends UPON the relative position of various PARTS of a system. A SPRING has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the GROUND than it has after falling to Earth.

it will appear PURPLE or VIOLET .

ong>Answer:

The answer is VACUUM or AIR MARK me as the brainliest FRIEND

INCIDENT RAY is the answer

ong>Answer:

The stranger asked the boy if he could TELL him the WAY to the nearest hotel and the boy replied that he could tell the way and added a question whether he WANTED a residential one in which he could spend the night. The man said that he don't wanted to STAY there but he only wanted a meal so, the boy then replied that the hotel named Paradis GARDEN would be better for him.

ong>ANSWER:

the WORK done on an OBJECT does not depend on (d)initial VELOCITY of the object.

Both A and B.

Hope it HELPS you.

ong>Answer:

C is the CORRECT answer

Explanation:

ong>Answer:

WEIGHT of a BODY DEPENDS on mass of the body and accel eration due ro GRAVITY.

MASS

Explanation:

because mass is very LES

ong>Answer:

First make a parallel combination of two 6 ohm RESISTORS. The effective resistance of this combination BECOMES 3 ohm. ( 1/R1 = 1/R2 + 1/R3) Make the same parallel combination for the other two remaining resistors. Join these two combinations in series with EACHOTHER. The effective resistance now becomes 6 ohm. (R1 = R2 + R3)

ong>ANSWER:

A concave MIRROR can focus solar rays to a POINT.

[C]=decreases

Explanation:

rong> Answer :

For two mirrors PLACED at 90 DEGREE to each other o = 90 degree

no. of IMAGE formed = 360 degree over 90 degree -1

= 4-1 = 3

i.e,.3 image will be formed.

A is the CORRECT option hope it is HELPFUL to you

Celsius (or "degrees Celsius", or sometimes "Centigrade"), is a TEMPERATURE scale.

It is used to tell how HOT or cold something is

It is often written as °C

Water FREEZES at 0°C and BOILS at 100°C

Fahrenheit is a temperature scale.

It is used to tell how hot or cold something is.

It is often written as °F

Water freezes at 32° F and boils at 212° F

The PHYSICAL QUANTITY is SPEED.

The STATEMENT is false because The transfer of HEAT by RADIATION does not REQUIRE any medium

I THINK it is TRUE HOPE it HELP you

Ya they are conductor of HEAT but not good conductor of heat ✌✌.

i hope it HELPS U buddy ✌✌

A device that utilises solar energy for cooking purposes is called a solar cooker. The most commonly used form of solar cooker is known as box-type solar cooker. A box-type solar cooker is SHOWN in the figure.

Construction of a box-type solar cooker: A box-type solar cooker consists of the following components:

Box (B): This is an insulated metal or a WOODEN box. It is painted black from inside because black surface absorbs more heat. The box may be provided with four roll-wheels.Glass cover (G): A cover made of two sheets of toughened glass held together in an aluminium frame is used as a cover of the box B.Plane mirror reflector ®: A plane mirror reflector fixed in a frame is fixed to the box B with the help of hinges. The mirror reflector can be positioned at any DESIRED angle to the box. The mirror is positioned so as to allow the reflected sunlight FALL on the glass cover of the box.Cooking containers ©: A set of containers made of aluminium and blackened from outside are kept in the box B. These containers are also painted black because black surface absorbs more heat.

Working: The food is cooked in a shallow vessel of the container. The box has a transparent covering of glass sheet over it. The solar cooker is placed in sunlight and reflector (plane mirror) is adjusted in such a way that a strong beam of sunlight enters the box through the glass sheet. The blackened metal surfaces in the wooden box ABSORB infra-red radiations from the beam of sunlight and heat produced raises the temperature of blackened metal surface to about 100°C.
The food absorbs heat from the black surface and gets cooked. The thick glass sheet does not allow the heat produced to escape and thus, helps in raising the temperature in the box to a sufficiently high degree to cook the food.

293-273=20°c

Answer:

The sun HEATS the earth through radiation. Since there is no medium in the atmosphere , radiation is the primary way that heat travels in space. The received heat warms the MOLECULES of the AIR , and thus , heats the atmosphere.

When heat falls on a object , the object absorbs heat and radiate photons.

Solution:-

gievn by , 
Radius of the drop = 0.30mm
= 0.30 X 10^-3 m 

Volume of the OIL drop = (4/3)×(pi)×(0.30x 10^-3)^3 ..............(1) 

The circular film is cylinderical with radius 0.12m (given) and thickness 't' m(SAY). 

Volume of the film = (pi) × (0.12)^2 × t .......(2) 

at EQUAT to equetion》

(4/3)×(pi)×(0.30x 10^-3)^3 =(pi) × (0.12)^2 × t

t = ((4/3)×(pi)×(0.30x 10^-3)^3)/(pi) × (0.12)^2

t =( 4/3)×(0.30x 10^-3)^3/144×10^4

t = (36×10^-6)/144×10^4

t = 0.25×10^-10


NOTE: We have found only the thickness of the film and not the size of the oil molecule.

Hey!!!

__________

We have

R1 = 4 ohm
R2 = 2 ohm
R3 = 2 ohm
V = 10V

Let R be the EQUIVALENT RESISTANCE of the circuit

Here R2 and R3 are in parallel

=> 1/Rp = 1/R2 + 1/R3

=> 1/Rp = 1/2 + 1/2

=> Rp = 1 ohm

Thus R = R1 + Rp

=> R = 1 + 4

=> R = 5 ohm

Again By Ohm's Law

=> V = I x R

Thus I = V/R

=> I = 10/5

=> I = 2A

Thus the AMMETER reading will be 2A

____________

Note : Ammeter is connected in series not in parallel

Hope this helps ✌️

Bcoz of loose BOND or weak force of ATTRACTION between the molecules

The FOCAL LENGTH is HALF of RADIUS..
Focal length is 30/2=15cm

We know that the CHARGE of 1 electron = 1.6 x 10POWER minus19 coulomb
thus, 1.6 x 10power minus 19C of charge=1 electron.
therefore 1C= 1/1.6 x 10 power minus 19 electrons
                    = 10 power19/1.6 electrons
                    = 10 x 10power 18/1.6 electrons
                    =6.25 x 10 power18 electrons
