What's UR QUESTION....

To uniform VELOCITY
TAKE two same graphs of EQUAL velocity and ALSO take two CONGRUENT similar graphs

MECHANICAL ENERGY is CONSERVED

The RELATIVE DENSITY = 260

f=i+2j+k

s=4i+j+7K

work=f.s=1*4+2*+1*8=17j

First law of THERMODYNAMICS TELLS about the relation between the WORK DONE and heat. Second law tells about the possibility whether the first law occurs or not.

What is this !!!????


it's not a QUESTION RELATED to PHYSICS !!

The electric moment is a MEASURE of the separation of positive and NEGATIVE electrical CHARGES within a SYSTEM.
Hope it's help you.
Mark it BRAINLIEST.

600rv/min=10rev/sec=2π*10rad/s=20π

1500rev/min=25rev/sec=2π*25rad/s=50π

w2-w1= at

50π-20π=a6

a = 5πrad/sec

The above will HELP you☺☺☺

As you know, light BULB is made of a tungsten wire that has been kept a high temperature for many hours . High temperature evaporate tungsten from filament, decreases its radius . from , we see decreased cross sectional area leads to an increase in the resistance of the filament. this INCREASING resistance with age means that the filament will carry less current the same applied VOLTAGE. With less current in the filament, there is less output and then filament GLOWS dimly.

I hope you understand why brightness of bulb is observed to decrease GRADUALLY with its period of use.

Hey frnd....
PARALLAX method is used to find larger distance or the diameter of the objects at a larger extend.
for example... diameter of sun

in this method we put one sight on one corner n then just put that sight on ANOTHER corner between which we want to MEASURE length.
then we can find the ANGLE at which we have to move the sight for seeing the other corner.
then we can find the length of diameter using the distance n angle.

HOPE THIS HELP YOU ☺☺❤❤❤

An elastic COLLISION is defined as one in which both conservation of momentum and conservation of kinetic ENERGY are observed. This IMPLIES that there is no dissipative FORCE acting during the collision and that all of the kinetic energy of the objects before the collision is still in the form of kinetic energy afterward.

While

An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision

1 LAW first state earth ROTATE in elliptical orbit
2 law second tell distance cover NEAR the sun or away from sun in same time it's area is same
3 law THIRD tell sure of time taken is propotinal to cube of distance around sun

The convex lens is CONVERGING lens and the concave lens is diverging lens. So, therefore THER is a DIFFERENCE in their FOCUS.

Hello Mate!

So, a man threw a mass if 2 kg with velocity of 20 m/s. Since we know that,

Potential Energy = mgh

But we don't have h i.e height so we will find it.

s = ut + ½at²

s = (20)(1) + ½(-10)(1)²

s = 20 - 5 = 15 m

So, potential energy = 2 kg × ( - 10 m/s² ) × 15 m

= - 20 N × 15 m = - 300 J

Hence potential energy is 300 J but against gravity.

Have GREAT FUTURE ahead!

i =v/r
I = 16 / 2
I = 8 A

It INCREASES when ADDED to H20

Ryken is the CORRECT ANSWER

WORK done will be 0 as FORCE is ALWAYS perpendicular to the VELOCITY vector.

We KNOW that I=q/t
q=It
=0.5*10*60
=5*60
=300 C

A- At the middle of total HIEGHT the KINETIC energy and POTENTIAL energy will be equal

B- hieght is not GIVEN

Is THOUGHT that the Solar System formed according to what is known as the Nebular Hypothesis. About 4.5 billion years ago it is believed that the Solar System CONSISTED of a large cloud of gas and dust, called a nebula. This cloud started rotating, and the dust PARTICLES combined to FORM planetesimals. As the cloud rotated FASTER, it flattened, and the planetesimals combined to form, first of all, the Sun at the center, and secondly, the planets in orbit around the Sun. This model explains qualitatively many features of the Solar System, including the fact that the planets essentially all revolve around the Sun in the same plane.

Hii dear,

# Answer- temperature difference between body and surroundings

# Newton's law of cooling-

It STATES that the rate of heat loss of a body is directly proportional to the difference in the temperatures between the body and its surroundings provided the temperature difference is SMALL and the NATURE of RADIATING surface remains same.

dT/dt = k × (T2-T1)

This law doesn't mention radius/area/volume of sphere so rate of cooling is independent of radius of metal ball.

Hope that cleared your DOUBTS...

How to PREPARE for the naso level 1 EXAM :

1.go to google and if there is sample papers for the naso levEl 1 exam, try it.

2.revise the SYLLABUS throughly.

3. if you have any friends who have written this exam , ask them how they prepared for the exam.

AND ALL THE BEST !!☺☺

hope it helped :)

Earthquake hazards include any physical PHENOMENON associated with an earthquake that may PRODUCE adverse effects on human activities. While they are OFTEN used as synonyms, it is useful to distinguish between "hazards" and "risk". Hazards are the natural phenomena that might impact a region, regardless of WHETHER there is anyone around to experience them or not. Risk refers to what we stand to lose when the hazard occurs; it is what we have BUILT that's threatened. Risk can be usually be measured in dollars or fatalities, Hazard is generally measured in more physical units: energy, shaking strength, depth of water inundation, etc.

Primary earthquake hazards are:

ground shaking  

landslides  

liquefaction

surface rupture

Secondary earthquake hazards are those that are caused by the primary hazards, and may often be more catastrophic:

tsunami

seiche

flooding

fire

Heya mate, Here is UR answer

Higher the slope of a line, less is the resistance. And we know that the CONDUCTOR that has the lowest resistance is the best conductor.

Now looking at the graph, we can say, that S has the HIGHEST slope meaning lowest resistance. So, S is the best conductor among all 4 .

2) We know that,

Resistance= RHO l/A

Now, rho( resistivity of the material) and l (length) is same, which is the thicker most.

More the resistance, less the area of cross section (thickness) .

To calculate the thickest WIRE, the resistance should be less.

Since the lowest resistance is of S, S must also have the largest area of cross section. Thus, S is the thickest wire.

Which QUESTION ????????

Hii FRIEND,

# Answer- 112.5kW

# GIVEN-

C = 50 microfarad = 50×10^-6 farad

V = 3000 V

t = 2 ms = 2×10^-3 s

# Formula-

Power of the pulse is given by,

Power = 1/2 CV^2 / t

Power = (1/2×50×10^-6×3000^2)/(2×10^-3)

Power = 112500 W

Power = 112.5 kW

Power of the pulse is close to 112kW.

Thanks for asking...

Answer:
A STICK or a pencil half immersed in water at an angle appears bent due to refraction of light at the air-water surface. Figure shows a STRAIGHT stick AO whose LOWER portion BO is immersed in water. It appears to be bent at point B in the direction BI. A ray of light OC coming from the lower end O passes from water into air at C and gets refracted away from the normal in the direction CX.Another ray OD gets refracted in the direction DY. The two refracted ray CX and DY, when produced backward, appear to meet at point I, nearer to the water surface than O. Similarly each part of the immersed portion of the stick raised. As a result immersed portion of the stick appears to be bent when viewed at an angle from outside.

The instrument ment is TELESCOPE Saturn's RINGS

In 1610, the year after Galileo Galilei first turned a telescope to the sky, he BECAME the very first person to observe Saturn's rings, though he COULD not see them well enough to discern their true nature.[1]

By January 1610, he had SIGHTED the four massive Galilean moons with his 30× magnification telescope, [2]
