pls mark me brainliest Explanation:A solenoid is a type of ELECTROMAGNET, the purpose of which is to generate a controlled magnetic field through a coil wound into a TIGHTLY packed helix. The coil can be arranged to produce a uniform magnetic field in a volume of space when an electric current is passed through it.The material used to make solenoid iron CORE is not pure iron, it is ferriferous OXIDE. The iron core of solenoid is used to enhance the magnetism of the solenoid, therefore, you just NEED to choose the materials with magnetic permeability larger than 1, for example, the metal oxides like manganese, cobalt, etc.

tion:Force is defined as a PHYSICAL cause which CHANGES the SIZE or shape of a BODY or changes it state of rest or of MOTION.

Any PHYSICAL quantity is termed as a vector quantity when the quantity has MAGNITUDE and DIRECTION. ... THEREFORE, an electric current is a scalar quantity although it POSSESSES magnitude and directionl

F1-F2Explanation:we know that the resultant will be their difference as their vectors are acting at 180 degree .GIVEN that F1 is greater than F2 so F NET will go in DIRECTION of F1.

-y = d(5t² x³)/dxSince we are DIFFERENTIATING system w.r.t 'x'. It MEANS there is no use of 5t². dy/dx = d(5t² x³)/dxdy/dx = 3x²Concept :-While differentiating we SEE only what we are going to differentiate with respect to. Like if in this question we are asked to differentiate (5t² x³) w.r.t 'r'Then simply as there is no TERM like 'r' in the system. Hence our ANSWER will be zero. But if only one term is given and we are given two terms then we differentiate that asked term only and that other term becomes zero by itself.

here is your answer⬆⬆⬆⬆hope it's HELPFUL..... MARK as BRAINLIEST..... TQ

i don't SURE about the ANSWER . so sorry OTHERS can help youExplanation:PLEASE mark me as brainlst

The PRINCIPLE of an electric motor is based on the CURRENT CARRYING CONDUCTOR which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it EXPERIENCES a force.

ut+ 21 at 2 In first 2 s,s=20m20= 21 a(2) 2 =2aa=10 m/s 2 VELOCITY at the end of 2 s is v=u+at=0+10×2=20m/sIn next 4S, s=ut+ 21 a ′ t 2 160=20×4+ 21 a ′ (4) 2 80=8a ′ a ′ =10 m/s 2 It shows that acceleration is UNIFORM. From v=u+atv=0+10×7=70 m/s

here is ur answer....❤️Magnetic field due to moving charges and ELECTRIC currentsAll moving charged PARTICLES produce magnetic fields. Moving point charges, such as electrons, produce complicated but well known magnetic fields that depend on the charge, VELOCITY, and acceleration of the particles.mark me as BRAINLIEST and follow me ✌️...TAMANNA 073

(C) Displacement reactionExplanation:Aluminium being more REACTIVE than iron DISPLACES iron and RESULTS in the formation of aluminium oxide.Hope you GOT the answer:)

given vectors are DENOTED by A and B Then, A+B= -2i+J+4k. If the REQUIRED vector is ai+bj+ CK Then, (a-2)i +(b+1)j +(c+4)k = k, as PER given in the question.Hence comparing the components, we get a=2, b = -1 and c = -3. Therefore the answer is 2i -j - 3k.

tion:Dynamics is the branch of physics developed in classical MECHANICS concerned with the study of forces and their effects on motion. ISAAC Newton was the FIRST to formulate the FUNDAMENTAL physical laws that govern dynamics in classical non-relativistic physics, ESPECIALLY his second law of motion.

if the directional COSINES are GIVEN as (0, 0, 1), then it means the Z axes. The directional cosines of X axes is (1, 0, 0). ... If the direction of the line (or the POSITION vector) is reversed, then the directional cosines are cos (π-α) , cos ( π-β), cos (π- γ).Explanation:Please mark as brainliest.....

The FORMULA for FORCE SAYS force is equal to mass (m) multiplied by acceleration (a).

When detergent is added to water, it DECREASES the SURFACE tension of the water. Compounds that lower water's surface tension are called surfactants, which work by SEPARATING the water molecules from one another.

Given, A =4 i^ +3 j^ +6 k^ and B =− i^ +3 j^ −8 k^ A + B = 3 i^ +6 j^ −2 k^ To make it a unit vector, we'll have to divide it by it's magnitude which is 7.Hence the unit vector is, 73 i^ +6 j^ −2 k^ EXPLANATION:please mark as brainlist and thanks

(a) 32 grams is correct optionExplanation:ONE MOLE of oxygen GAS, which has the formula O2, has a mass of 32 G and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.Hope you got the answer:)
