2021-22] Notes: India and Guatemala have signed a pact for strengthening diplomatic cooperation through Respective Foreign Service Institutes in the educational field. The agreement was recently inked after a meeting between Vice President M Venkaiah Naidu and his Guatemala counterpart, Jafeth Cabrera Franco in Guatemala City. Beside this, both the countries agreed to support each other’s candidature for Non-Permanent Membership in the United Nations Security Council (UNSC). Guatemala will support India’s candidature for UNSC membership for 2021-22 while New Delhi will do so for 2031-32 for Guatemala. During the talks, Indian side also agreed to the Guatemala’s request for supplying solar panels to its airports. After discussions and in the presence of both the Vice Presidents, both the sides signed a Memorandum of Understanding (MoU) for training of diplomats and a Letter of Intent for training Guatemalan English Teachers in India. These agreements will be valid for three years and will be extended thereafter, if required.

The reading in the spring , should be sum of both the forces acting on the block = (5+10)g = 15g = 150N

we know thatQ=iTSO 5*3mA15mC

what is that relation between same magnitued and opposite direction so that u given the answer 20m/s

in horizontal direcn.50sin30 = 2*aa = 50/4 = 25/2 = 12.5 m/s^2hence the accln. of 2 kg mass is 12.5 m/s^2.

in horizontal direcn.50sin30 = 2*aa = 50/4 = 25/2 = 12.5 m/s^2hence the accln. of 2 kg mass is 12.5 m/s^2.

The product of the distance (2 l) between the twopolesand thepole strengthof eitherpoleis calledmagneticdipole moment. Its SI unit is 'joule/tesla' or 'ampere-metre^2'. Its direction is from southpoletowards northpole. Where θ is angle between the dipoleaxisandmagneticfield.

For question b , kindly post the image.

We know that C = 5/9*(F-32) => F = 9C/5 +32 ....(1)

so, when c is increased to C+30

=> F' = 9(c+30)/5 +32 =9C/5 +9*30/5+32 = 9C/5 +32+ 9*6

=> F' = F+54 ....... ( since 9c/5 +32 = F)

so, in Fahrenheit ,the increase is = 54°F

it's wrong

check it again.. just missed a 9 to be multiplied with 6, while expanding the formula..

thank

(30°C× 9/5) + 32 = 86°FAs farehneit scale starts from 32°Hence Reading will be 86-32=54°F

Center of mass= 3*50+2*50= 150+100250/5= 50

i think t1 is 8N

thanks 😀😀

is it correct?

ya......

Let i be the current flowing in the circuit

By Kirchhoff’s law

38i = 200 – 10

=> i = 190/38

=> i = 5A

We know, Capacitive reactance(Xc) =1÷(2*3.14*f*C)

=1÷(2*3.14*50*10*10^-6) {~1 uF=10^-6 F~}

=318 ohms(approx.)

Again voltage across capacitor =200V

So, Current across capacitor =200÷318=0.7 A

*The calculation was done assuming peak voltage =200 V.

If 200V is the R.M.S value then peak voltage would be 200*root over of 2=283 V

So current =283÷318= 0.89A = 0.6√2 A

it is not in option and solution not understandable

thank you ... your answer is correct....

It is the power rating for the bulb.(A power rating is a measurement of the maximum amount of power that can be used with a specific tool or device.)

Power = 250 WVoltage = 230 V

It indicates two factors:(i) Maximum power that the bulb can be used with and (ii) Amount of energy that the bulb consumes.

Multiply the number of hours the bulb is used on an average day by the wattage. This will give you the watt-hours or energy consumed per day.

it means that the amount of electricity bulb can transform into light over a given amount of time. here the

Mean gamma = Mean Cp/Mean Cv = 3/2 = 1.5

This number of electrons has to be removed.

This number of electrons has to be removed.

a]=[t2]=T2

[P]=T2/[bx]

[b]=T2/[P][x]=T2/ML-1T-2L=M-1T4

a/b=T2/M-1T4=MT-2

R is the difference .

Case 1:Initial velocity = 36km/h=10 m/sFinal velocity = 72km/h= 20m/sTime taken = 5 sAcceleration =( 20 -10)/5= 10/5= 2m/s^2Case 2:Initial velocity = 72km/h= 20m/sFinal velocity = 0m/sAcceleration = (0-20)/20= -1m/s^2So, retardation = 1m/s^2

An electric motor converts electrical energy into mechanical energy.Principle;It works on the principle of the magnetic effect of current. A current-carrying coil rotates in a magnetic field. The following figure shows a simple electric motor.

Working:

When a current is allowed to flow through the coil MNST by closing the switch, the coil starts rotating anti-clockwise. This happens because a downward force acts on length MN and at the same time, an upward force acts on length ST. As a result, the coil rotates anti-clockwise.

Function of split ring:The split ring in the electric motor also known as a commutator reverses the direction of current flowing through the coil after every half rotation of the coil. Due to this the coil continues to rotatein the same direction
