The relation of moving charge is the cause of energy.

Answer»

Magnetic force can cause a CHARGED particle to move in a circular or spiral path. Cosmic rays are energetic charged particles in outer space, some of which APPROACH the Earth. They can be forced into spiral paths by the Earth’s magnetic field. Protons in giant accelerators are kept in a circular path by magnetic force. The bubble chamber photograph in Figure 1 shows charged particles moving in such curved paths. The curved paths of charged particles in magnetic fields are the basis of a number of phenomena and can even be used ANALYTICALLY, such as in a mass spectrometer.Explanation:Because the magnetic force F supplies the centripetal force Fc, we haveqvB=mv2rqvB=mv2r.Solving for r yieldsr=mvqBr=mvqB.Here, r is the radius of curvature of the path of a charged particle with mass m and charge q, moving at a speed vperpendicular to a magnetic field of strength B. If the VELOCITY is not perpendicular to the magnetic field, then vis the component of the velocity perpendicular to the field. The component of the velocity parallel to the field is unaffected, since the magnetic force is zero for motion parallel to the field. This produces a spiral motion rather than a circular one.

Three resistors each of 9Ω to be connected in which way to get a resultant resistance of 6.25Ω.

Answer» TION:U can't get 6.25 but can get 6 ohms.First, connect 2 RESISTORS in series, so R=9+9=18ohms.Now, connect this R to other 9 ohm in Parallel.So, 1/(R(net))=(1/9)+(1/18)R(net)=18x9/(18+9)=18x9/27=6 ohmsSo, net RESISTANCE is 6 ohms.Thank you

Acar initially at rest starts moving with an acceleration of 4 ms. The time in which itpicks up a velocity of 72 ms is dash second​

Answer»

iven that CAR initially at rest MOVING with an ACCELERATION of 4 m/s² acquires a velocity of 72 m/sWe have to find time taken by car to acquire that velocity.SolutionAs the car is initially at rest, so initial speed i.e. u = 0 m/sFinal velocity (v) = 72 m/sAcceleration (a) = 4 m/s² ★ Using 1st equation of MOTION :➝ v = u + atPutting values :➝ 72 = 0 + 4t➝ 72 = 4t➝ t = 72/4➝ t = 18 seconds.Hence, time taken by car to acquire that velocity = 18 seconds.________________________________ ★ Some more equations : ➼ s = ut + ½ at² ➺ h = ut + ½ gt² ➼ v² - u² = 2as ➺ a = (v - u)/t

State the uses of lenses in everyday life

Answer»

Concave lenses are used for correcting myopia or short-sightedness. Convex lenses are used for focusing light rays to make items appear larger and clearer, such as with magnifying glasses.A concave lens contains at LEAST one inwardly-curved surface, and it is also referred to as a divergent lens. When light rays enter a concave lens, it diverts, or spreads, the rays around because of its thinner center, causing the OBJECTS to appear smaller or farther away. A car's side mirror is one example of a concave lens, and it often comes with the warning "objects in mirror are closer than they appear."A convex lens, also KNOWN as a converging lens, is identified by its thicker middle and thin outer edges. It consolidates the rays of light that travel through it, as opposed to diverting and spreading them the way a concave lens does. When light passes through the lens, it CONVERGES into a single point of focus called the principal focus. Camera lenses are convex, as they focus all rays of light onto the subject being photographed to make that subject appear clearer. A magnifying glass is ANOTHER example of a convex lens; once the lens is placed close enough to the object, it will produce an upright, virtual image of the object.Explanation:PLEASE MARK AS BRAINLIEST ANSWER
