tion:If Torque = 0 ; that means either FORCE(PERPENDICULAR) = 0 , or Radius = 0; Case I : If Force(perpendicular) = 0; that means Acceleration(perpendicular) will be EQUAL to 0; therefore Velocity(perpendicular) won't change . This implies Angular Momentum (L=mvr) won't change. Angular Momentum remains constant.Please mark this answer as BRAINLIEST

End rule is used to determine the polarity of the SOLENOID. Considering on ENDS of the solenoid,if the circular face of the CURRENT flows in the anticlockwise direction, the that end becomes the N pole and if the current flows in the clockwise direction,then that end becomes the S pole.Hope U liked my answer....plz comment...

The PARTICLES that carry charge along conductors are free electrons. The ELECTRIC field direction within a circuit is by definition the direction that positive TEST charges are pushed. Thus, these negatively CHARGED electrons move in the direction opposite the electric field.

eans WATER. Water is a RENEWABLE source as it EVAPORATES and then come back to earth in the FORM of water or ice.That's why hydro-power is a renewable source of ENERGY.

for maximum height here initial VELOCITY = 10m/s now we find TIME of ascent ,time of ascent = USIN (THETA)/g =10sin 45°/10 = 10/10 = 1s

I am now 8 th standard but I TRY to FIND out this QUESTION

refer to the IMAGE. I have TRIED to make it simple CLEAR. If CALCULATIONS are needed(for acceleration) then you can simply APPLY third law of motion.Please Mark brainliest if you are satisfied.

they USED EQUATION of MOTION Explanation:according to question what is given and what they are asking

.....!!!!!!!!NOTE: REFER to the ATTACHMENT

i don't KNOW PLZ GIVE me ANSWER

11.75m/secExplanation:HOPE it will be HELPFUL for U....

see the image attached. In the second step, I have reduced the CIRCUIT with PARALLEL connections. Then the REST is in SERIES.

energy of rotation is E = 1/2 I w^2, where I is the moment of inertia and w the ANGULAR frequency of rotation. The moment of inertia of a solid sphere of mass 2kg and radius 1m is: Is = 2/5 *2 *1^2, WHILST that of a solid cylinder is of mass 2kg radius 1mabout its central AXES is independent of its height and equals IC = 1/2 *2*1^2 So we want to equate the energies through 1/2 *2/5 *2*1^2 * (w_sphere)^2 = 1/2 * 1/2* 2*1^2 * (w_cyl)^2 (w_cyl)^2 = 4/5 (w_sphere)^2 w_cyl = +-sqrt(4/5) ω (NOTE that the energy of rotation is independent of the direction of rotation, so we have two solutions).Dr.

It is the SHORTEST distance or POINT at which our eye is capable to change its focal LENGTH to focus on.

it HELPS you PLZZ FOLLOW me ☺☺

Electromagnetic Induction is a CURRENT produced because of voltage production (electromotive FORCE) due to a changing magnetic field. This either happens when a conductor is placed in a moving magnetic field (when using AC power source) or when a conductor is constantly moving in a stationary magnetic field. Michael Faraday ARRANGED a conducting wire as per the setup given below, ATTACHED to a device to measure the voltage across the circuit. When a bar magnet was MOVED through the coiling, the voltage detector measures voltage in the circuit. Explanation:

An electromagnet is a magnet that runs on ELECTRICITY. UNLIKE a PERMANENT magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. ... An electromagnet works because an electric current produces a magnetic field.

SURGERY...THAT WILL REPLACE THE CLOUDY LENS WOTH NEW ONE THAT IS ARTIFICIAL.

the VALUE of G is 9.8 m/s2

tion:4s is CORRECT answerffff

i don't KNOW the ANSWER it is BEST THING

The direction of magnetic field will be exactly between the current axis and the axis of force ( in ACCORDANCE to FLEMING's left HAND rule)

......!!!!!!!Apply the FORMULA to calculate MINIMUM DISTANCE........=>v²-u²=2ass=v²-u²/2aHere v=25m/su=15m/sa=1m/s²Thens=(25)²-(15)²/2*1=200m

hi i am new in this APP can U PLEASE HELP me in everything

No MATTER AROUND US is not 100% PURE..

we know that,Force = Mass * Displacement.so if displacement is CONSTANT then Force VARIES directly with Mass. So for MOVING a heavy object for a PARTICULAR DISTANCE more force is required than moving a non heavy object for same distance .

(A) zeroforce is VECTOR QUANTITYAND it will CANCEL

tion:Let us derive the RELATION of force F = ma from Newton’s second law: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.It means that the linear momentum will change FASTER when a bigger force is applied.Consider a body of mass ‘m’ moving with VELOCITY v.The linear momentum of a body is given by:p = mvNow According to Newton’s 2nd Law of Motion:Force is directly proportional to rate of change of momnetum, that isF α dp/dtF = k dp/dtF = k d(mv)/dtF = k md(v)/dtF = k maExperimentally k =1F = k maWhich is the REQUIRED equation of force.

Ratio = 1:4:9Explanation:In the question,Initial velocity of the body, u= 0 m/sAcceleration, a = a m/s² (constant)Also,KINETIC ENERGY is given by,So,At the end of 1st second,At the end of 2nd second,Similarly, at the end of 3rd second,So,Ratio of Kinetic Energies at 1st, 2nd and 3rd second will be,

wer should be a 50km/hr.Train 1 speed=40km/h = 40*5/18 m/sTrain 2 speed = v m/sDistance travelled = (SPEED1 + speed2) * time [The speeds need to be added as the trains are COMING towards each other]=> 75 = (100/9+v) * 3=> v = 125/9 m/s = 125/9*18/5 km/h = 50km/h
