ANSWER:

Explanation:

Base is much NARROWER and thinner than COLLECTORS,hence the majority of charge carriers are received by collector.Hence,collector CURRENT is greater than base current.

Spring constant is not INVERSELY proportional to length.

proportional is taken when OTHERS are constant.

here force on spring is not constant.

if length is small ,force is ALSO small.
and if length is high ,force on springs is also high.
so as k=F/l it will not change.

spring constant is ALWAYS constant for a specific spring for small values of l.

In thermodynamics the total ENERGY can not be UTILISE in WORK so that's why ISOLATED thermodynamics does not exist

A because it can't obey the triangle LAW of VECTOR QUANTITY

The infrared spectrum is absorbed by glass PRISM and therefore, we cannot see the infrared spectrum through a glass prism. WHEREAS, a ROCK SALT prism doesn't ABSORB these infrared spectrum and we could see the infrared spectrum through it.

R = 4/0.4
R= 10 OHMS

Here is your ANSWER BRO

Because they are not ABLE to PRODUCE IONS but GRAPHITE is EXCEPTION

Both will have same displacement.

displacement of PLAYER one is 1 run.

displacement of Player2 two when he complete first run will 1 run,

when he completes 2 run he comes to starting POINT again so his displacement is zero.

when he completes third run its displacement is 1 run.

It is between 40 to 60 TIMES

Vector QUANTITY are quantity in which they are defined by both its MAGNITUDE and as well as DIRECTION l.

Ex :- DISPLACEMENT, Velocity, ETC.

There are 3 Newton's laws of motion.

Newton's FIRST law:

If a body is in the state of rest , it remains to be in state of rest until an external force is applied on it.

Similarly, if a body is in the state of motion, it remains in the state of motion until an external force is applied on it.

This property of an object to remain in its state is called Inertia.

There are two types of inertia

1. Inertia of rest

2. Inertia of motion.

Newton's second law:

ACCORDING to Newton's second law the force applied on a body is directly proportional to the rate of change in momentum.

We know that

Momentum = mass * velocity

Acceleration = Change in velocity/time

⇒ velocity = acceleration * time

So,

Momentum = mass * acceleration * time

Momentum = Force * time [As F = ma]

Force = Change in momentum/change in time

Newton's third law of motion:

According to Newton's third law, for every action, there will be an equal and opposite reaction.

For example:

If a book is placed on a table, the book exerts some amount of force on the table and the table also exerts the same amount of force on the book keeping the net force 0. So, the book remains in rest.

I HOPE you understand my EXPLANATION and also this helps you.

Product COMPONENTS of an ENDOTHERMIC reaction have a higher HEAT CONTENT

Creep is essentially a slow process of PLASTIC deformation under the action of stress is below the yield of STRENGTH of material. A typical curve of deformation versus loading time.

A Creep curve usually CONSISTS of three portions corresponding to PARTICULAR STAGES of creep.

They FIND older remains in the deep because they have been dugged there for thousand of years and now have changed into FOSSILS. at lower LEVELS there are more fossils

No solar eclips is not a uncommon PHENOMENON.total solar ECLIPSES are rare at any particular location because TOTALITY exists only along a narrow path on the EARTH's SURFACE traced by the Moon's shadow or umbra. An eclipse is a natural phenomenon.

Hey, ✋ there your answer________,

▶ The Romans ACTUALLY got the name Milky Way from the Greeks, who CALLED our galaxy “galaxias kyklos” or “milky circle.”

The Romans named it via lactea precisely because it looks like a milky PATCH of SKY above the Earth at night.

✔ Hope it MAY helps u....!!!

The PARALLEL comes and GETS reflected from the concave mirror and being a concave mirror it converges the BEAM of LIGHT at the focus.

When the distance is smaller , we use Dm ( decimetre , CM(centimetre) and mm ( millimetre) . These are CALLED the SUBMULTIPLES of Metre.

The force which oppose motion is CALLED FRICTION.

when twó surface (rough) surface rub against each other it produces friction

Here is your ANSWER.....

Because in liquid and GASES,intermollecullar SPACE is more due to this waves bands at spaces in liquid and GAS

The CHARGE stored in CAPACITOR is directly proportional to VOLTAGE.

so if voltage is tripled,charge stored is ALSO tripled.

Because they RELEASE hamful gases LIKE carbon mono OXIDE which is very harmful for our heath.

As many others point out, there isfriction present, otherwise the wheel wouldn't grap the surface and pull the car forward. But you are talking about a different kind of friction. There is a possibility of different kinds of friction:

Kinetic friction, if the wheel ever slides and skids over the asphalt. This is friction between objects that slide over one another.STATIC friction, which is what the other answers talk about. This is friction that holds something still. It always works in the direction that prevents two objects from sliding. The point on the wheel that touches the ground experiences static friction, because it is standing still in that very negligibly small moment.

But

rolling friction is what you are refering to. Ideally there is no kinetic friction, and static friction only grabs the asphalt and doesn't reduce the speed (on horizontal surface and without wheel torque). All other FORCES that do work against the wheel rotation (except friction around the axle, as you also point out) are COLLECTIVELY called rolling friction.

Rolling friction happens of several different reasons. For example,

the rubber tires contract and expand and thus dissipate energy. The energy is taken from the rotation, and this factor COUNTS as rolling friction. Alsothe ground underneath might deform. The deformation costs energy and will as well cause a surface with normal forces that do not act radially (towards the wheel's center) anymore. Such forces will cause torques that might counteract the rotation. See the above picture.
Without rolling friction (in an ideal world), the car will continue to roll and NEVER stop. I believe this is the actual question that you have. Because you are right that in this sense, friction counteracting the motion has been eliminated as you describe.

Because the PREASSURE is low in HILLS TJIS is the reason

The planet with the most MOONS in the Solar SYSTEM is Jupiter, with a TOTAL of 63 confirmed moons

Resultant of FORCES is zero if the vectors FORM a TRIANGLE.

so in triangle the sum of any TWO sides is GREATER than the third side.

in this condition,4+5=9 that is less than 10 .

so these doesn't make a triangle and thus resultant is not zero.

Let the TOTAL distance to be covered equals to S.

The distance covered in 6 hrs by each will be :

Let A be the one travelling at 9km/h and B be the one travelling at 15 km/h

Distance of A is : 6 × 9 = 54 km

Distance of B is : 15 × 6 = 90km

The distance remaining for A is : S - 54

For B is : S - 90

A doubles his SPEED and this becomes 2 × 9 = 18km/h

They will TAKE the same TIME to reach their DESTINATION :

(S - 54) / 18 = (S - 90) / 15

15(S - 54) = (S - 90)18

15S - 810 = 18S - 1620

3S = 810

S = 270

Time = (270 - 90) / 15 = 12

The answer is 12 hrs.
