d/t40 = d/9360 km = DistanceNow at 60 km/h60= 360/tt = 360/60t = 6 hoursHence the CAR will take 6 hrs to cover the same distance at 60km/hr

mirrors are used in solar FURNACES, because CONCAVE mirrors are the only type of mirror that reflects light in toward a single FOCAL POINT. A flat mirror does not have a focal point. It does regular reflection off all of its points. ... The light will REFLECT up and away from the focal point of a convex mirror.

vity of WIRE A , = 1.62 × 10^-8 OHM. m resistivity of wire B , = 4.68 × 10^-8 ohm . m Let length of wire B is lthen, length of wire A will be 2lsimilarly , Let's assume that DIAMETER of wire A is d then, diameter of wire B will be 2d.we know, where R is resistance, is resistivity, l is the length of the wire and a is CROSS sectional area. so, resistance of wire A , and resistance of wire B,

proposed by Sir Isaac Newton that expresses the force of gravitational attraction between TWO bodies as a function of their masses and their distance. Expressed mathematically, F = Gm1m2/d2 where F is the force in Newtons, m1 and m2 are the masses of the bodies in kilograms, G is the gravitational constant, and d is the distance between the bodies in meters.Newton's law of GRAVITATION n (General Physics) the principle that two particles ATTRACT each other with forces directly proportional to the product of their masses divided by the square of the distance between themNewton's law of gravitation The principle that two bodies exert a gravitational attraction for each other that increases as their masses increase and as the distance between them decreases. In mathematical TERMS, the force equals the product of the two masses multiplied by the gravitational constant and divided by the square of the distance. Also called law of gravitation, law of universal gravitation. See NOTE at gravity.hope it will help you...pls mark as brainliest

istance to change, the greater is the elasticity of the MATERIAL and the faster it comes BACK to its original shape or configuration when the deforming force is removed .For a given STRESS (stretching force per unit area)strain is MUCH smaller insteel then in rubber and hence the answer.

Given that,  Acceleration (a) = 10m/s²  Time (t) = 10 sec.  Initial VELOCITY (u) = 0m/s² (as the vehicle is starting from rest.)  To find,   The distance travelled in the last seconds = ?   From the SECOND equation of motion,   s = ut + 1/2 at²  s = 0 * 10 + 1/2 * 10 * 10 * 10  s = 0 + 1/2 * 1000  s = 1/2 + 1000  s = 500mTherefore, the distance travelled in the last seconds is 500M.

fundamental frequency of the SPRING is fThen frequency of its OCTAVE is 2f.f = K (T)1/22f = K(T')1/2 Hence T' = 4TT' = 4*4 = 16 KG- wt

What’s the Difference Between Dark Matter and Dark EnergyDark matter and dark energy are the yin and yang of the cosmos. Dark matter produces an attractive force (GRAVITY), while dark energy produces a REPULSIVE force (antigravity). Together, they make up 96 percent of the UNIVERSE and we can’t see either. Astronomers know dark matter exists because visible matter doesn’t have ENOUGH GRAVITATIONAL muster to hold galaxies together. Hey it is dark not black matter

nductivity is the ability of CERTAIN materials to conduct electric CURRENT with practically zero resistance. This capacity produces interesting and potentially useful effects. For a material to BEHAVE as a superconductor, LOW temperatures are required.

conservation of ENERGY states that Energy can neither be created nor be DESTROYED but can be transferred from one form to another.In the case of free falling body P.E converts into K.ECase 1:Consider an object of mass(m) which is made to fall freely from a certain HEIGHT(h).At the starting point A, P.E is maximum & K.E is minimum because the velocity of an object become zero.Total energy(T.E) = P.E + K.E                       T.E = P.E + 0                       T.E = mghCase 2:At point B(mid-point in air), the velocity of an object will increase & height of the object will decrease hence the P.E will be CONVERTED into K.E.Total energy(T.E) = P.E + K.E                      T.E  = mgh + 1/2mv^2(square)Case 3:At point C(slightly above the ground in air), an object is just above the ground & body will have a certain velocity & acquire a K.E.Total energy(T.E) = P.E + K.E                        T.E = 0 + K.E                        T.E = 1/2MV^2(square)CONCLUSION:The sum of energies is same at all points.Potential energy(P.E) + K.E = Constant      mgh + 1/2mv^2(square) = Constant = Mechanical energy(M.E)

rear view mirror has a RADIUS of curvature of 4M. An image of a bus is formed 1.5m behind the mirror.find the actual distance of the vehicle from the mirror and compare the size of the bus with the image seen in the mirror.Radius of curvature  = R = 4 m Focal length f = R / 2 = 4 / 2 = 2 mObject distance U = - 1.5 m Image distance = v 1 / f = 1/u + 1/v1 / 2 = 1/v - 1/1.5 1/v = 1/2 + 1/1.51/v = 7/6v =  0.857 mThe distance of image is 0.857 mmagnification m = -v/u                   m = - 0.857 / -1.5 = 0.571So the size of the image is 0.571 times that of the object

superconductors can be defined as a substance which are capable of becoming superconducting at sufficiently low temperatures.Superconductors are very good diamagnets: when a magnetic field is applied on these, eddy current flows in the superconductor result in the inducing of a magnetic field which cancel the EFFECT of applied magnetic field. This is also CALLED as "Meissner Effect".there are many magnetic properties of super conductors INCLUDING CONDUCTIVITY and those aresuper conductors are perfect diamagnets they can pass critical current , josephon current through themthey can also create magnetic fieldhence superconductors cannot be completely designed to only conduct or to work as a conductor they can perform other tasks as well

with defined RATING should not be REPLACED by one with a larger rating because even if there is large FLOW of current the fuse will CONTINUE to allow the current but will not fuse and it will possibly lead to short-circuit or overloading.____May this help you ❤️___
