Explanation:

When a ray of light approaches a SMOOTH polished surface and the light ray bounces back, it is called the reflection of light. The INCIDENT light ray which lands upon the surface is said to be REFLECTED off the surface. The ray that bounces back is called the reflected ray. If a perpendicular were to be DRAWN on a reflecting surface, it would be called normal. The figure below shows the reflection of an incident BEAM on a plane mirror.

ANSWER:

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the ATMOSPHERE, where they MIX and react with water, oxygen, and other chemicals to FORM more acidic pollutants, known as acid rain.

Answer:

Magnetite like MATERIALS are called MAGNETS now.

ANSWER:

• Whenever there is no light there is darkness. Reason is simple. Light source FACES the object. So on front side light falls i.e light can reach there. But in the opposite side light can not reach so there remains darkness or shdow.
• Place an object between two light source one with higher INTENSITY(brightness) and other with lower intensity. Sources should be PLACED on opposite side of the object. You can see the shadow in the side of the lower intensity light. That's also a light source but shadow will be on that side.

Answer:

Irons are rather simple in how they work. They work like an electric heater. They have a heating element made out of a metal alloy that gets HOT when electricity is applied. Wired in series with the heating element is a thermostat. The thermostat is made of two electrical CONTACTS that are designed to bend away from each other as the iron gets hot. The knob turns a SCREW which control how hard the contacts must bend to separate and break the electrical connection. The higher the thermostat is turned, the hotter the iron must get before the electrical contacts separate. Then when the iron starts to cool, the contacts make connection again, thus keeping the iron steadily at the desired temperature.Basically you apply a voltage to a load (the iron's heating element) which induces a current. The current through the load generates heat according to the formula Power = Current^2 * Resistance.

The heat produced in conducting wire is given by joules law as,

H=I²Rt

i ) The amount of heat produced in current conducting wire, is proportional to the square of the amount of current that is FLOWING through the circuit, when the electrical resistance of the wire and the time of current flow is constant.

 i.e H∝I²    (when R, t are constant)

II) Heat generated due to the flow of current  is proportional to the time of current flow, when the electrical resistance and amount of current flow is constant.

  ie H∝t (when I,R are constant)

III) The amount of heat produced is proportional to the electrical resistance of the wire when the current in the circuit and the time of current  flow is constant.

  ie H∝R (when I, t are constant)

The pulmonary arteries and the pulmonary veins are the vessels of the pulmonary CIRCULATION; which MEANS they are RESPONSIBLE for CARRYING the oxygenated BLOOD to the heart from the lungs and carrying the deoxygenated blood from the heart to the lungs.

As we know that atoms loses and gains electrons and forms ATOMIC bond so we can SAY that atoms are living. PROTEINS and Carbohydrates are the molecules without no organisms can live so we can say that molecules are also living. cell ORGANELLE is helps in in reproduction in humans so we can say that they are also living.

1. A STEEL is 40 cm long at 20 OC. The coefficient of linear expansion for steel is 12 X 10-6 (Co)-1. The increase in length and the final length when it is at 70 oC will be…

Known :

The change in temperature (ΔT) = 70oC – 20oC = 50oC

The ORIGINAL length (L1) = 40 cm

Coefficient of linear expansion for steel (α) = 12 x 10-6 (Co)-1

Wanted : The change in length (ΔL) and the final length (L2)

Solution :

a) The change in length (ΔL)

ΔL = α L1 ΔT

ΔL = (12×10-6 oC-1)(40 cm)(50oC)

ΔL = (10-6)(24 x 103) cm

ΔL = 24 x 10-3 cm

ΔL = 24 / 103 cm

ΔL = 24 / 1000 cm

ΔL = 0.024 cm

b) The final length (L2)

L2 = L1 + ΔL

L2 = 40 cm + 0.024 cm

L2 = 40.024

✒ Anything which we eat to live is called food. For example: Roti ,bread ,BUTTER ,fruits vegetables, pulses, vegetable oil, butter, desi ghee, EGGS, meat, chicken , fish, egg etc. Food is necessary for us because it provides matter for the growth of our BODY and energy to do work .Plants and animals are the main SOURCE of food for all the organisms on earth. Food obtained from animals is the main source of protein and include fish, milk, meat, poultry, and cheese. Whereas plants provide us with fruits and vegetables, which are an important source of fibres, PROTEINS and carbohydrates.
