Hola!!

●Radius of Curvature = 25 × 2 CM = 50 cm.

Hope this HELPS you ___!!

heya!!

_________________________________⭐⭐⭐

your answer is option (3)

→ we have mirror formula as

1/F = 1/v. + 1/u

on differentiating both sides we get

-df/f^2. = -dv/v^2. - du/u^2

in terms of % error it is written as,

df/f × 100. = f(dv/v^2. + du/u^2)

HOPE it helps!!

Simple Science Experiments: Newton’s Third Law Of Motion

Posted by yifadmin

In: Physics

1 Comment

Newton’s third law states that for every action there is an equal, but opposite, reaction. Help students understand Newton’s third law of motion by carrying out a few activities in your classroom.

Balloon rockets

Materials needed: TAPE, drinking STRAWS, balloons

Divide the students into pairs and give each pair some tape, a drinking straw and a balloon. Ask one of the students to BLOW up the balloon and hold the mouth of the balloon closed. Now, ask each pair of students to tape the balloon to the straw carefully ensuring that the air does not escape from the balloon. The student holding the mouth of the balloon closed should then release the balloon at the same time as the other student who is holding the straw. The students will see that the balloon moves like a rocket dragging the straw along with it.

This activity DEMONSTRATES Newton’s third law of motion. The force of the air rushing out of the balloon creates enough force to push the balloon and straw in the opposite direction.

Answer:

1=5m/s2     2=you do it plz LIKE me

Explanation:

U (initial velocity)=5m/s                                  u=5m/s

v (final velocity) =30m/s                                 v=30m/s

t (TIME) = 5sec                                                 a=5m/s2

                                                                        t=5sec

,we know                            

                                                                        we know

a=30m/s-5m/s                                                s=u+v

          5m/s                                                     t    2

a=25m/s                                                         s=u+v MUTIPLY t

Answer:the type of wave propagate DIRECTION that a parallel to membrane PLANE , with but the membrane itself ,get displaced up and down PERPENDICULAR ,to that plane is called transverse wave.

standing WAVES is also known as stationary wave ,it is a wave which oscillate in time whose PEAK amplitude profile does not move in space.

Linear Momentum. ... The momentum is a vector QUANTITY, where the direction of the momentum will be as same as the direction of the VELOCITY. Momentum is directly proportional to both velocity and MASS. The linear momentum will ALWAYS be conserved if there is no external force is PRESENT.

Answer:

NEWTON's second law is actually about linear momentum which actually motion in a straight line for ex. if U KICK a ball it will GO in a specific direction and in straight line. that's what Newton's second law STATES.

===========

We know that when a charged particle enters a UNIFORM magnetic field the force exerted on it,

F = Q(v X B) = qvb sin∅

Case I : when the particle enters perpendicular,∅ = 90

In this case since sin∅ = 1 is the maximum value and the direction of the force is perpendicular to the direction of motion of particle, hence the particle starts moving in a CIRCULAR path with radius,

r= mv/bq

Case II : the particle enters at an ANGLE of 30⁰:

In this case the force acting on it has two components, one parallel to the motion which will cause a linear motion, the other component will ACT perpendicular to motion which will cause circular motion.

Hence DUE to the resultant of these two component the particle will move along a HELICAL path.

Explanation:

The main disadvantage of microwave transmission is that microwave towers can EXCHANGE data only if they have a clear line of SIGHT between them with no obstacles such as buildings, slopes or trees in the way. DIFFERENT DISADVANTAGES incorporate signal absorption by the atmosphere, weather obstruction and COST.

where are your NUMERICAL QUESTIONS......

Answer:

36 km/h

Explanation:

let the DISTANCE covered with 20km/ph be x then time TAKEN will be x/20 sec

now distance left to be travellex will be 2x and time taken will be 2x/60 sec

so total distance covered will be 3x and total time taken will be x/12 sec

so average VELOCITY will be total distance travelled /total time taken

therefore average velocity all be 3x/x/12 that will be 36 km/hr.........!!!!!!

Hii its tom85

we know that

T.E = work function + k.E

given

E= 5.6*10^-19j

k.E=12*10^-20j

work function=T.E - K.E

work function=56*10^-20 - 12*10^-20

work function=10^-20(56 - 12)

work function=44*10^-20

work function =4.4*10^-19j

work function = it is define as the the amount of energy give to the metal SURFACE to eject a electron on

its surface .

concept

when large amount of energy(photon) given on the surface of metal it eject electron and ALSO increase its kinetic energy .

so T.E = k.E + work function

photoelectric EFFECT show that partical NATURE of electron .

Answer:

In physics a drift velocity is the AVERAGE velocity ATTAINED by charged particles, such as electrons, in a material DUE to an ELECTRIC FIELD. In general, an electron in a conductor will propagate randomly at the Fermi velocity, resulting in an average velocity of zero.

Answer:

Heyy buddy,

We have 2 conditions in this particular case:

1)If the car strikes u from the opposite direction,then the TOTAL VELOCITY turns out to be ZERO(60-60).

2)If the car strikes u from behind,which means that you as well as the car are in the same direction,the total velocity turns out to be 120m/s(60+60).

Hope I'm clear.

Acceleration vs time GRAPH gives US change in velocity with respect to first equation of UNIFORMITY accelerated motion.

Initial velocity = 0

Change in velocity in first two seconds
V=2*2= 4 m/s

Change in velocity fron 4th to FIFTH second
V'= -4*1= -4 m/s

Therefore velocity after 5TH second is zero
i.e. particle again comes at rest.


Displacement covered in first two seconds = 4 m

Displacement covered in next two seconds =8 m

Displacement covered in next second= -4 m

net Displacement = 4 + 8 -4 =8 m

Answer:

REST is the state of an object being STATIONARY relative to a particular frame of reference or ANOTHER object; when the POSITION of a body with respect to its surroundings does not change with time it is said to be "at rest".

Answer:

hola MATE

YES, displacement can be ZERO For eg if we travelled from point 0 to point A n then travelled BACK from point A to O the final position confides with the initial position.Therefore, displacement is zero

Answer:Why Selling Can Be a Drag, and How to Overcome

In any GIVEN year, I’ll have thousands of great ideas in my business, but most of them die in my mind. A good amount of them make it through to pen and paper, I actually keep a Google doc of ideas. From there, a smaller group actually GET acted upon. Finally, one or two a year actually survive.

All of us entrepreneurs have great ideas. We’re visionary. But there are a couple of things we need to be aware of.

The more aligned you are with your purpose and with what God has for you, the more resistance you’re going to meet.

If you don’t believe in your product, you won’t have the strength to fight through this resistance.

We want to believe that we can control everything. So if SOMEONE says no to our idea, product or service, we want to think logically and say “well, maybe it’s a bad idea or product.”

But what if the resistance is there to teach you to wait, refine your approach, and develop the faith and courage that the early church had to endure to spread the gospel.

In Acts 13, we see Saul and Barnabas going around to various cities, TALKING with Jewish leaders and letting them know about Jesus. Although some received them warmly, and most have them plenty of time to explain themselves, there is a “FORCE” that exists that does not want this message to spread. This force will do anything to stop them, but Saul was so bold and so driven with purpose that he would dust his sandals off and move on.
