The factors on which UTILISATION of resources DEPENDS are;Availability of resources SKILL of HUMAN beings.Availability of capital.Availability of water.Advancement of technology.Availability of transport and communication facilities.Hope it helps you.

When we HEAT a conductor, its constituent ATOMS get excited and start vibrating more.This means that the free electrons (the ONES which give rise to the ‘current’) there’s a potential difference between the ends of the conductorcollide more and more with the atoms in the conductor and get ‘hindered’. Thus, the conductor becomes more resistant to the flow of current through it.BUT On the other hand, if you cool a conductor, its atoms VIBRATE less, and the electrons find it EASIER to move, making the conductor less resistant.Explanation:

A lunar eclipse occurs when the Moon MOVES into the EARTH's shadow. This can occur only when the Sun, Earth, and Moon are EXACTLY or very closely aligned (in SYZYGY), with Earth between the other two. A lunar eclipse can occur only on the night of a FULL moon.

Final Velocity Formula vf=vi+aΔt. For a given INITIAL velocity of an object, you can multiply the ACCELERATION due to a FORCE by the time the force is applied and ADD it to the initial velocity to GET the final velocity.Hope it helps you!!

tion:Uniform velocity: -a BODY has a uniform velocity of it travels in a straight line and MOVES over EQUAL distances in equal INTERVALS of time.NON uniform velocity: -a body has a non uniform velocity if it travels unequal distance in equal intervals of time.PLS MARK AS BRAINLIEST ANSWER

• Initial VELOCITY(u) = 45 km/hr • Final Velocity (v) = 10 km/hr • Time = 6 seconds To Find : • Acceleration of the car Solution : FIRST of all convert the given Velocity into their proper unit. For Converting km/hr into m/s we've to multiply the unit with ● 45 km/hr → 45 × →12.5 m/s ● 10 km/hr → 10 × → 2.78 m/sLet's find Acceleration now : We know that, Acceleration of the car is -1.62ms⁻¹

A vector is described by both DIRECTION and magnitude . Examples of scalar QUANTITIES include time , volume , speed, MASS , temperature , distance, ENTROPY, energy , work , … Example of vector quantities include acceleration , velocity , momentum , force , increase and decrease in temperature , weight.

⚫Uniform or constant acceleration is a type of motion in which the VELOCITY of an object changes by an equal AMOUNT in EVERY equal time PERIOD. A frequently cited example of uniform acceleration is that of an object in free fall in a uniform gravitational field.⚫Non uniform acceleration is the velocity of increasing by unequal amount in equal intervals of time. It MEANS that the acceleration is not constant.

The TIME INTERVAL (t) varies from one instance to another, on which the values of velocity and the AVERAGE ACCELERATION depend.If t = 0, vx(t) = vx (0) = 0, thus the average acceleration is also calculated to be 0.

:Acceleration is 1.25 m/sExplanation :INITIAL velocity (u) = 10 m/sFinal velocity (v) = 15 m/sDistance (s) = 5 mUse 3rd equation of motion :_____________________Important Points to Remember :Acceleration is DEFINED as Rate of CHANGE of velocity. It is a VECTOR quantity. It is denoted by “a”SI unit is m/s²

(c) Frictional FORCE Explanation:Frictional force arises dute relative motion between the object and a surface and it's ALWAYS opposite to the DIRECTION of motion.To note: Frictional force is due to electromagnetic interactions between atoms of present in the object and that of the surface.
