Explanation:The use of magnetic fields as a tool for control and measurement has important medical applications. Present devices include magnets to remove objects from the eye and to facilitate the withdrawal of swallowed safety pins and similar objects, ensuring that the sharp end POINTS backwards. In more sophisticated applications magnetic materials are purposely introduced into the body to accomplish various TASKS. Magnetically guided catheters have been used to negotiate the tortuous passageways of blood vessels. FERRITE powders MAY replace barium sulfate for gastrointestinal x‐ray diagnosis in some applications. Magnetic fields have also been used for various measurements, employing not only fields due to small amounts of material artificially introduced into the body but also the extremely weak fields produced by the electrical or electromagnetic activity of the body itself.

Since, values for forces are not given.Resultant R is = Explanation:Because the formula for resultant of forces (VECTOR ADDITION) is under root HOPE THIS HELPED!!

In a paramagnetic MATERIAL, themagnetization of the material is (APPROXIMATELY) directly proportional to an applied magnetic field. HOWEVER, if the material is heated, this proportionality is reduced: for a FIXED value of the field, themagnetization is (approximately) inversely proportional to temperature.

tion:1824,In 1824, when he was only 15 years OLD, Braille developed a six-dot “cell” SYSTEM. He used Barbier's system as a starting point and cut its 12-dot CONFIGURATION in half. The system was first published in 1829; a more complete elaboration APPEARED in 1837.

tion:Given:Mass of METALLIC ball = 500 gm=0.5 kgVelocity : 36 km/h = 10m/sIn the SI System:k = m*v => 0.5*10 => 5 kg m/s

Atomic bombs RELY on FISSION, or atom-splitting, just as nuclear power plants do. The HYDROGEN bomb, also called the thermonuclear bomb, uses fusion, or atomic nuclei coming together, to produce EXPLOSIVE energy. Stars also produce energy through fusion.

I THINK so it is 10 upwardsExplanation:

So, in reality, the CALCULATED distance (980 meters) to the target in this question would have to be revised to be CLOSER if it were to be REACHED in the 10 (+ ignored vertical air resistance EFFECT) seconds. A projectile is fired horizontally with a velocity of 98 m/s from the TOP of a hill that is 490 m high.

tion:The potential energy function for a system is given by U(x)=−4x3+5x2+7x, where x is in meters and U is in Joules.a) Determine the force Fx on the particle as a function of x.b) For what values of x is the force equal to zero?c) PLOT U(x) versus x and Fx versus x and INDICATE the POINTS of stable and unstable equilibrium.Potential Energy and Force:When an object has potential energy, either gravitational, elastic or some other type, it has a force acting on it. The force on the object is the negative derivative of the potential energy function. The graph of this function SHOWS locations of stable and unstable equilibrium.Answer and Explanation:(a) The force equation is F(x)=12x2−10x−7(b) The force is zero at x = -0.453 m and 1.29 m.(c) There are TWO positions of equilibrium,.

The reading should be taken by keeping the level of mercury along the line of SIGHT. Before USE, the mercury level should be below 35°C. WASH the thermometer with WATER or an antiseptic solution before and after use. Never hold the thermometer by the bulb while reading it.hope it helped and PLS mark me as brainliest:)

3m/sV(bc) = 3m/sV(cd) = 3m/savg velocity = [V(AB) + V(bc) + V(cd)]/3= (3+3+3)/3 = 3m/s

Francium is the liquid radioactive element.Explanation:It a chemical element with the symbol Fr and atomic NUMBER 87. PRIOR to its discovery, it was referred to as eka-caesium. It is EXTREMELY radioactive; its most stable isotope, francium-223 (originally called ACTINIUM K after the NATURAL decay chain it appears in), has a half-life of only 22 minutes.

give me thanks and follow me Cassettes and computer "floppy" DISKS use MAGNETIC fields to store the information. Storing a cassettes (or reel-to-reel) or floppy disk next to them will erase them. NOTE that magnetized scissors, and that LITTLE magnet at the top of a paper clip holder will ALSO erase them! Television, ESPECIALLY color television, uses magnetic fields to control the picture. Storing a magnet next to a television can cause the picture to look bad -- but the damage is usually not permanent. maybe it is useful for you nowRead more on Brainly.in - brainly.in/question/1335140#readmore

The FINAL QUANTITY you get when ADDING or subtracting VECTORS is called the resultant vector. In other words, the individual vectors can be replaced by the resultant – the overall EFFECT is the same.

osmosis is the PROCESS by which plant get water from the soil by the help of SEMI premeable membrane. whereasIn case of diffusion the plannt get water directly from the soil. other defination of diffusion is FLOW of energy from high CONCENTRATION to LOW concentration

s×d!!!!!!!!!!!!

is the SI unit of electric charge which is equal to the AMOUNT of charge transported by a CURRENT of one ampere in one second. It is denoted by C. It is named after Charles- AUGUSTIN de Coulomb who discovered the Coulomb’s law. Mathematically, 1 Coulomb = 1 Ampere × 1 second.Hope this helps

wer depends all on the density of WOOD.If density of wood is more than the body of WATER, UPTHRUST WOULD be less and wood will sink.However, if density of wood is less (it would be less if the PIECE is small), upthrust is more and it would float.Thanks and have a great afternoon :)

Mass (m) = 8000 kgInitial Velocity (u) = 20 m/sFinal Velocity (V) = 0 m/s (since it is coming to rest)Distance (s) = 50 mv^2 = u^2 + 2as, where, acceleration = a0 = (20)^2 + 2(a)500 = 400 + 100a-400 = 100aa = -400/100a = -4 m/s^2f = m.a, where FORCE = f = 8000 ( -4) = -32000 NewtonThanks and have a great AFTERNOON, :)

yesExplanation:PROTONS and NEUTRONS have APPROXIMATELY the same mass, about 1.67 × 10-24 grams, or 1 AMU

Figure of the projectile motion in the attachment.The initial velocity of the BODY = 98 m/s.The HEIGHT of the hill = 490 m.Find the velocity at which the body STRIKES the ground = ?Finding the time :⇒ s_y = (u_y)t + ½(a_y)t²⇒ 490 = 0 + ½(9.8)(t²)⇒ t = 10 sWe know that, v_x = u_x + (a_x)t⇒ v_x = 98 + 0 = 98 m/sAnd, v_y = u_y + (a_y)t⇒ v_y = 0 + (9.8)(10) = 98 m/sSo, v = √[(v_x)² + (v_y)²]⇒ v = √(98)² + (98)²⇒ v = 98√2 m/sHence, the speed at which the body will strike the ground = 98√2 m/s.

According to the convention if a pivotic magnet is ALLOWED to MOVE freely the PART of the magnet pointing TOWARD the North is said to be North pole of the magnet and viceversa. Though it is EXPLAINED in this way North pole of a magnet and the North pole of Earth are unlike poles.And for this reason the North pole of the magnet points toward the unlike pole(North pole of Earth).

It will show a CHANGE.Explanation:A vector has TWO components : It's magnitude and direction. If either of these are CHANGED, so it's the vector. Thus, unless SHIFTED PARALLELY, the vector will change.

because, bar magnets are in the form of a bar, with two ends, NAMELY in this CASE, NORTH pole and south pole.Thanks and have a great day! :))

A solenoid is an essential coil of wire that is used in electromagnets, inductors, ANTENNAS, valves, etc. The application of a solenoid differs in numerous types like MEDICAL, locking SYSTEMS, industrial use, the BOTTOM line and Automotive Solenoid Applications.Explanation:PLZ MARK MY ANSWER AS BRAINLIST AND FOLLOW ME
