HEYA MATE,

HERE IS UR ANSWER.

Thanks for asking this question.

Here, INITIAL speed, u = 90 kmh-1 = 90 x(5/18) = 25 ms-1
Acceleration, a = – 0.5 ms-2
Train brought to rest, so final speed, v = 0
From third equation of motion, v2 = U2 + 2as
0 = (25)2 + 2 x 0.5 x s
0 = 625 – s
s = 625 m

I HOPE IT HELPS U.

Velocity is a vector QUANTITY. This means velocity has a magnitude and a direction.The magnitude of velocity is speed.Let's hold magnitude constant.If we CHANGE direction thenwe are changing velocity without changing the speed!Circular motion is a PRIME example of thisconcept because the speed can stay the same, but the object has changing velocity. The acceleration is toward the center at EVERY point.Note: Since we are changing velocity then we must have anacceleration. Acceleration is defined as a change in velocity over change in time.

According to LAW of CONSERVATION of CHARGE, charge in neither be created and nor be DESTROYED.

It takes 4 sec to reach
so time TAKEN during going upward is 2 sec
and time taken during LOW ward is 2 sec
after 2 sec it's velocity becomes zero because it reached its highest POINT
so distance of ball after 3 sec from START
s=1/2 gt^2=1/2×10×1=5meter from its highest point

The DISTANCE COVERED is 3/4(2πr)=6πr
.displacement=√{r^2+r^2}=r√2

(a) An equilibrium state is STABLE state , if on disturbing the magnet , it comes back to same initial state . so BAR magnet is in stable equilibrium at
potential ENERGY ,
here, M is the magnetic moment.e.g., M = 0.32J/T
B is the magnetic field.e.g., B=0.15T
so, U = - 0.32 × 0.15 = -0.048J

(b)A bar magnet is unstable equilibrium, if on disturbing from its position, it further GETS disturb and do not come back to previous position of equilibrium.
at the equilibrium is unstable.
so, potential energy, U = -MBcos180°
U = MB = 0.32 × 0.15 = 0.048 J

Effects of force are:
1)CHANGE the shape.
ex:1) when we apply a force on a sponge it changes it's shape..

2) it's direction.
ex:when we hit a ROLLING BALL it's direction changes.
3)it's size.
ex:when we tear a PAPER by applying force it's size is changed..

I hope it HELPS you;)

Where is FIGURE here

Because the LUGGAGE may fall DUE to inertia of direction or motion

The VALUE of F is G that is 9.8 NEWTON.

As the temperature INCREASES


the DENSITY decreases



because the kinetic energy is increased
which in turn accelerate the MOTION of particles


their INTERMOLECULAR spaces BECOME wide
so their density decrease

In this arrangement, if any ONE of the component STOPS working, then the circuit gets broken up and none of the device will work.
all the appliances have only one switch DUE to which they cannot be turned on or off separately .
the appliances do not get the same VOLTAGE (220V) as that of the power supply line

Can U GIVE me any QUESTION

☺☺HEY MATE YOUR ANSWER IS HERE. ...☺☺


A couple is a pair of forces, equal in magnitude, oppositely directed, and displaced by perpendicular DISTANCE or MOMENT. The simplest KIND of couple consists of two equal and OPPOSITE forces whose lines of action do not coincide.

Explanation:

HOPEFULLY it will HELP you DEAR: )

Acceleration in t sec,


a=X/t




Acceleration in NEXT t SECOND it moves ANOTHER x distance
=>x+x=2x
. . y+y=2y


a=2x/2y


a=x/y



. IT IS A LINEAR ACCELERATION, moves EQUAL distance in equal time.





SO THE DISTANCE TRAVELED IN NEXT x sec IS 2x meter.

Hey mate.......

According to the Newton's 2ND LAW of motion, the RATE of change of linear momentum of a body is directly proportional to the applied external force and in the direction of force. ... Newton's 2nd Law of Motion: Rate of change of momentum(p) is directly proportional to the force(F) acting on it in the direction of force.

Consider a body of mass ‘m’ moving with velocity v.

The linear momentum of a body is given by:

p = mv

Now According to Newton’s 2nd Law of Motion:

Force is directly proportional to rate of change of momnetum, that is

F α dp/dt

F = k dp/dt

F = k d(mv)/dt

F = k MD(v)/dt

F = k ma

Experimentally k =1

F = k ma

STEPS in NUTRITION :
INGESTION
DIGESTION
ABSORPTION
Assimilation
Egestion

It happens due to MAGNETIC EFFECT of electric current.The NEEDLE DEFLECTS due to the magnnetic FLUX assosiated with it.

Contact Force :- Contact force are the TYPES of force which act only when body is in physical contact with other OBJECT .
e.x. :- pushing a door
pulling a doll by string .

There are various types of contact FORCES :-
1. Frictional force .
2. Normal Reaction Force.
3. Tension Force .
4. Due to collision .


Non -contact force :- Non contact Force are the type of force which act when body is not in physical contact with other one .
e.x. :- Falling of apple from tree.
Iron Nails ATTRACTED from magnet.


There are various types of Non- contact Force :-
1. Magnetic Force.
2. Electrostatic Force .
3. Gravitational force.

So we're to UNDERSTAND 1920" as

19203600 DEGREES =19203600⋅2π360 radians

So we're LOOKING at a diameter

d=1.496×1011⋅19203600⋅2π360 METERS

d=1.39254×109 meters

Hi Intelligent...................●●●●●

Here is your answer....................◆◆◆◆◆

If we APPLY force and throw a ball upward then by the POWERFUL force applied by a person will help the ball to go to only a certain height only.
Then after reaching at certain height , the ball will fell a loss in ENERGY and it will start coming down at fast speed.

So,here I have GIVEN my view,HOPE this will help you

Answer=27
proof:
ACCELERATION=(FINAL VELOCITY-initial velocity)÷time taken
=54-0÷2
=26

Can CHANGE the DIRECTION,SPEED,VELOCITY,POSITION,

Radon GAS is ALSO known as mass gas until the 118 the element is not known to us(Uuo)

After 2.2 SEC LATER they will MEET each other

volume of 20 ice CUBES =125×20=2500cm ke power 3

Examples of sliding frictions are:-
1.)Rubbing both hand TOGETHER to CRATE a heat.
2.)A coaster sliding against a table.
3.)A sled sliding across SNOW or ice.
4.)Skis sliding against snow.
5.)A block being slid across the floor.

Hope it helps you!!!!!!!!!!

F=mv^2÷r ...................

In MECHANICS problems like these, we’ll usually use one of the following 5 equations:

Refer the figure::

Since we don’t have a time, we can eliminate equations 1, 2, 3, and 5.

For EQUATION 4, we need an initial velocity (u), a FINAL velocity (v), and an acceleration (a). We’re given an initial velocity of 30 ms^-1 and the acceleration due to gravity is -9.81 ms^-2. At the maximum height, the velocity will be 0 ms^-1 — therefore the final velocity is 0 ms^-1.

Solving for s (DISPLACEMENT — which will give us the heigh):

v^2 = u^2 + 2as

v^2 - u^2 = 2as

(v^2 - u^2) / 2a = s

s = ((0 m/s)^2 - (30 m/s)^2) / 2(-9.81 m/s^2) = -900 / -19.62 = 45.9 m

The centripetal force is the center seeking force. That is when a objects revolve around something such as EARTH around Sun and Moon around Earth the gravity of the Sun and the Moon creates a centripetal force.That brings the OBJECT near it and keeps it MOVING in a ciruclar PATH.

Distance is the path traveled by an object from ONE point to another WHEREAS DISPLACEMENT is the SHORTEST distance traveled by an object.

V=65 m /s
= (65× 10^-3) / (1÷3600) km/hour { as 1 SEC= 1÷3600 hour and 1m= 10^-3 km}
= 234 km / hour

Here you GO. it's πr because it has TRAVELLED HALF of its CIRCUMFERENCE

✴Mass:-
