Because TIME TAKES PLACE in PERIODS

3=u+0.5a
8=2u+2a
a=2
u=2

The MIRROR FORMULA is 1/f=1/v+1/u

Light does not change ENERGY (frequency) when it moves from ONE medium to another. HOWEVER, it does slow down as the velocity and wavelength decrease. This is represented by the index of refraction which is >1 for natural materials. ... Energy = planck's constant*frequency, hence no change in frequency .

It is because they are CHANGING their speed and direction with RESPECT to time. They are GETTING tired as they are revolving and hence conversion of energy TAKES place die to which they RADIATE energy

Hi

the CARBON COMPOUND CONTAINING double and triple bonds are are called as UNSATURATED compound.

hope it helps....

H.C. VERMA will be good for NCERT
Full marks MCQ SOLVING is ALSO NICE.

EMF, electromotive FORCE, refers to thevoltage DEVELOPED by an ELECTRICAL source. Potential DIFFERENCE refers to the observed difference in VOLTAGE between any two points in an open circuit. They are not quite the same thing.

No, it's not! Depends on lots of factors. PEOPLE have given good answers. But here's a fun fact. A US Navy guy died out of a 9V DC battery. The SPARK which you see off metal door knobs and SWEATERS in winter are a minimum of 10,000 V. I didn't die of it. It's the CURRENT that MATTERS –

Ray of light DEVIATES from its path because of the change in medium.

Here which it changes its initial medium of air to FINAL medium of GLASS.

This change in medium will decrease ITA speed and hence causes deflection of light.

Excess heat is rejected to the room, and the gas condenses to a liquid in the condenser. When the liquid enters the evaporator, it transitions to a MUCH lower PRESSURE, which CAUSES it to expand and BOIL as it collects heat from the food compartment. The low pressure, low temperature gas then returns to the COMPRESSOR.

Alloys have HIGH resistivity(low electrical CONDUCTIVITY) than the PURE metal, hence alloys don’t MELT or break at high temperature.

They form protective layer when first heated, so material beneath this layer will not oxidize, preventing the wire from breaking or burning out.

It would be difficult to WALK on the floor because the friction on the floor will be decreased due to SOAPY water and it will be SLIPPERY

This is the ANSWER to your QUESTION

What is the QUESTION only DISTANCE and TIME is GIVEN not question

F=p.A=0.5*500=250N.......

◆ this is answer ◆
Because, the IMAGE is smaller , more image can fit into the mirror , so a convex mirror provides for a larger field of view than a plane mirror . This is why they are USEFUL . They are used whenever a mirror with a large field of view is needed . For example , the passenger- SIDE REAR view mirror on a CAR is convex .

A paramagnetic MATERIAL has a constant relative permeability SLIGHTLY more than 1 . When a paramagnetic material, such as PLATINUM , is placed in a MAGNETIC field , it becomes slightly magnetized in the direction of the external field . A ferromagnetic material, such as iron, does not have a constant relative permeability .

Distance travelled by the boy in first 20 min

= 20/60h × 18 km/h = 6 km

let the speed for next 40 min be v km/h

so, distance travelled will be 40/60h × v kmph

= 2v/3 km

So, total distance = 6 + 2v/3 km

total TIME = 20 + 40 min = 60 min = 1 h

As AVERAGE speed = total distance/total time

so, 24 = (6 + 2v/3)/1 = (18 + 2v)/3

or, 24×3 = 18 + 2v

or, 2v = 72 - 18 = 54

so, v = 54/2 = 27 km/h

So, he should run at a speed of 27 km/h for 40 minutes.

PRINCIPLE In a pump STORAGE plant, pump turbines TRANSFER water to a high storage RESERVOIR during off-peak hours. The stored water can LATER be used to generate electricity to cover temporary peaks in demand from consumer or unplanned outages at other power plant.Apr 10, 2015

Pine oil used in froth floatation PROCESS because it does not have AFFINITY TOWARDS water (because of the hydrophobic chemicals as its cconstituents) and it attracts impurities which can be washed away.

VI = 36 × 1000÷ 3600 = 10m/s

VF -vi = at
A = vf - vi ÷ t
A = 0-10 ÷ 5
A = -2 m/ s2


2AS = vf2 - vi2
S = vf2 - vi2 ÷ 2a
S = (0)2 - (10)2 ÷ 2 × (-2)
S =- 100 ÷ - 4
S = 25 METER

Are you familiar with ordinary integrals? When we write an integral, we specify the “DIRECTION” that the integral is taken in. So, for example, when we write:[math]\displaystyle\int f(x)dx[/math]We mean to take the integral along the[math]x[/math]direction (that’s what the[math]dx[/math]specifies).A line integral is a similar idea, but rather than take the integral along one of the AXIS directions, we take the integral along some other path, which may even be curved. In the caseof your example, we integrate the electric fieldalong the electric field vectoritself. Since, in GENERAL, the electric field points in different directions in different parts of space, this means that the direction we integrate in can also change as we proceed along the path of integration.The reason for doing this is that the line integral of the ELECTRICFIELD between two points is PRECISELY equal to the potential difference between those two points. This makes sense, since the electric fieldis the gradient (three-dimensional spatial derivative) of the potential. So, integrating the electric field is the complementary operation to differentiating the potential.

Before I start my discussion here I would like to state the first two laws of Newton in their most correct forms: 1)1st Law: There exist frames of reference with respect to which every body continues to be at rest or in uniform motion in a straight line until compelled by an external force to change that state. Such frames are called inertial frames. 2)2nd Law: In an inertial FRAME, if external force be applied on a body to change its dynamic state, then rate of change of momentum of the body is directly proportional to the applied force. This constant of proportionality can be taken as 1, 2, 3 or anything as the laws are not experimental but axiomatic in the purview of classical mechanics. Newton took it as 1 reducing the proportionality to equality. Now many textbooks on physics derive Newton's First Law from his Second Law in the following manner: " From Newton's second law, considering mass of the body to be a non-zero constant:

PUTTING:

Which is our first law, no force MEANS no change of dynamic state." But had it been so, Newton wouldn't have enunciated his first law as a separate and independent one (though Newton's works, mathematically speaking, were absolutely non-rigorous and not precise at all, and I view them as a concoction of vague definitions, nice intuitions and distorted mathematics). Newton's three laws are form the axiomatic basis of classical mechanics and axioms cannot be proved from axioms within the same FORMAL system (thanks to Godel for the proof of this statement). Many books justify this fact by saying that during that time three was a favorite number for the physicists. Galileo's three laws of falling bodies, Kepler's three laws of planetary motion etc. The books argue that Newton's laws were three in number for the same reason. But this is absolutely not a healthy explanation. Notice that Newton's First Law asserts the existence of Inertial Frames. It is these frames where the Second Law holds. So the first law talks of the inertial frames. What is an inertial frame? Well, many books say that it is a frame where Newton's laws HOLD. But this somewhat cyclic. If instead, we define inertial frames as those which are at relative rest with respect to a free particle (i.e. a particle with no real forces being acted upon) then the Second Law axiomatically holds in such frames. However, using the Second Law, we cannot actually prove the EXISTENCE of inertial frames as talked of in the First Law. And hence using Newton's Second Law we CANNOT prove his First Law.

If the density of an object is GREATER than WATER ( 1 g / cm³ ) then that object will sink. If it is less than water's density, then the object will float.

Density = MASS / Volume

Volume of object = 350 cm³

Mass of object = 500 g

Density = 500 g / 350 cm³

Density = 1.42 g / cm³

Hence 1.42 > 1. This implies that the object will sink.

Mass of water displaced = Density of Water * Volume

=> Mass of water displaced = 1 g / cm³ * 350 cm³ = 350 g

Hence mass of water displaced = 350 g.
