Here the vehicle moves with constant velocity until t1 and then stops . Thus the most suitable answer is option (C)

answer is the body travels with constant speed upto time t1 and stops

accepting as best please

49 right answer bhai

Potential remains same in the resistors when they are connected in the parallel. ∴ Potential in both the bulbs will be same.

Now, For First Tungsten Bulb, Power = 50 W.Potential = 220 V

∵ Power = Potential × Current. ∴ Current = 50/220 Current = 0.22 A

For second Tungsten bulbs, Power = 60 W.Potential = 220 V.

∴ Current = 60/220 = 0.27 A

Now, Total current flowing = Current in 1st bulb + Current in 2nd bulb.= 0.22 + 0.27= 0.49 A

Hence, the total current flowing in the main conductor is 0.49 A

sorry its answer may be 0.49A

Focal power of lens = 1/f. (f=focal length)=L^-1

option 3 is the correct answer

how R=2

in CV=cp-R, how R=2

small resistors use coloured painted bands to indicate both their resistive value and their tolerance with the physical size of the resistor indicating its wattage rating. These coloured painted bands produce a system of identification generally known as a Resistors Colour Code.

They react, with the chlorine combining with theironand hydrogen being released in the form of hydrogengas.

Thankyou very much

perpendicular is the answer.

There isabasicdifference, because massistheactual amount of material containedin abody and is measured inkg, gm, etc. Whereasweightisthe force exerted bythegravity on that objectmg. Note thatmassis independent of everything butweight is different ontheearth, moon, etc.

Given terms are,

•Speed

•Mass

•Force

•Temperature

•Energy

All the terms there,except Force only,are scalar quantities. Force is a vector quantity.

Scalar Quantity- can be described as a quantity which has magnitude only,not direction. For example speed, mass, temperature, energy etc.

Vector Quantity- can be described as a quantity which has magnitude and direction both. For example force, velocity, displacement etc.

●Hence the odd term among the given term is Force.

option(c) is correct

read my question again sir.

The velocity of a point at the highest point of a wheel moving with a constant speed "v" on a horizontal road is 2v. This will be the velocity of the small blob of mud separating from the wheel at its highest point A. It would travel to B before falling.

Therefore the length of the point AB= 2vt.

The coefficient of static friction between the circular/cylindrical/spherical surface of the object and the ground is a factor that will determine whether the object will roll or slip. If the coefficient of static friction is high then it will roll or else it will slip.

it is in one word

Dispersion of light is the phenomenon of splitting of white light into its constituent colors. Dispersion happens when white light passes through a glass prism. The different colors of light waves have different speeds in any medium like glass. They have different bending amounts after refraction. Hence, they show up separately beside each other.

These colors are Violet, indigo, blue, green, yellow, orange, and red. The rainbow also is formed due to dispersion of light waves at tiny water droplet interface with atmospheric air.

A ray coming throught the focus will pass parallel to the principle axis.

option(c) is correct

the answer is Mr² of this question

explain plz

Acceleration on an inclined plane

a= g sinθ/ (1 + I/MR²)

for circular rings: I= MR²

so by putting the value in above equation we get

a= g sinθ/ 2

a = g sin30/2

a= g/4

Mgh = KE of translation + KE of rotationMgh= 1/2 Mv² + 1/2 Iω²Mgh = 1/2 M(ωR)² + 1/2 (1/2 MR²)ω²Mgh = 3/4 MR²ω²

KE of rotation = K= 1/2 Iω²= 1/2 (1/2 MR²) 4gh /3R²K= Mgh/ 3= 2 x 9.8 x 4/ 3=26.13 J

The centripetal force required by a planet to remain in the orbit around the sun is provided by the gravitational force of attraction between the planet and the sun.

The centripetal force (F) depends on the radius (r) of the planets orbit, mass (m) of the planet and orbital speed (v) of the planet.

F = mv2/r
