48km/hrExplanation:let x be the DISTANCE TRAVELLED by the car..x/2 be half the distance now time t taken by the car with a VELOCITY 40km/hr is x/80hr (time=distance/speed) time t taken by the car with a velocity 60km/hr is x/120 hr. now avg velocity= x/2+x/2                           x/80+x/120                          = x*9600                                200x                           = 48km/hr

tion:Lanthanoids are the elements in which the extra electron (also called differentiating electron) enters (n−2) f-orbital. Since (n−2) f-orbital lies comparatively deep WITHIN the inner to the penultimate shell, these elements are also called inner-transition elements.La(Z=57) to Lu(Z=71)(15 elements) are considered as Lanthanoids.The position of actinoides in periodic table:The actinoid series contains elements with atomic number 89 to 103 and is present in the third group of periodic table. The series is the row present below the LANTHANIDE series which is LOCATED UNDERNEATH the main body of the periodic table.pls pls pls pls mark me as brainliest...

4√2 ms^-1Explanation:Given :--. s = 10M. , a = 1.6 ms^-2 , u = 0 ms^-1By the THIRD equation of motion , V^2 = u^2 + 2as = 0 + 2× 1.6 × 10 = 2×16 = 32 ms^-1..v = √32 = 4√2 ms^-1 HOPE IT HELPS!!!

please mark as branliestExplanation:An hourglass (or sandglass, sand timer, sand clock or egg timer) is a device USED to measure the PASSAGE of time. It comprises two glass bulbs connected vertically by a narrow neck that allows a regulated flow of a substance (HISTORICALLY sand) from the upper bulb to the lower one. Typically the upper and lower bulbs are symmetric so that the hourglass will measure the same duration regardless of orientation. The specific duration of time a given hourglass measures is determined by factors including the quantity and coarseness of the particulate MATTER, the bulb size, and the neck width.Depictions of an hourglass as a symbol of the passage of time are found in art, especially on tombstones or other monuments, from ANTIQUITY to the present day.[citation needed] The form of a winged hourglass has been used as a literal depiction of the well-known Latin epitaph tempus fugit ("time flies").

friction is what keeps the box from moving without being pushed, and it must be overcome with a SUFFICIENT opposing force before the box will move.The static friction between two SURFACES is ALWAYS higher than the KINETIC friction (at LEAST, in practical, real-world applications).itzDopeGirl

it's the DIFFERENT BETWN the MASS and WEIGHT

(a) 0(b) (i) 5 (ii) 6 (iii) 5.625Explanation:(a) Magnitude of average velocity is 0 because DISPLACEMENT is 0 bacause initial position and final position is same. (b) (i) Initially he traveled at a speed 5Km in an hr. So in 30 min he travels 2.5 km that means he reaches market in 30 min. (ii) After the first 30min, i.e,. after reaching the market he travels at a speed of 7.5 km in 60 min. So in 20 min he travels 2.5 km. That means he reaches home. So the TOTAL distance traveled in first 50min is 2.5+2.5=5km(iii) After the first 30min, i.e,. after reaching the market he travels at a speed of 7.5 km in 60 min. So in 10 min he travels 1.25 km. So the total distance traveled in first 40MIN is 2.5+1.25=3.75km

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━Newton's laws of motion relate an object's motion to the forces acting on it. In the first law, an object will not CHANGE its motion unless a force acts on it. ... In the THIRD law, when TWO OBJECTS interact, they apply forces to each other of equal magnitude and opposite direction.━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

We need to calibrate our compass so that it compensates for the angle between MAGNETIC and GEOGRAPHIC north, referred to as declination. This allows us to use the compass needle, which points at magnetic north, to navigate along a path REFERENCED to true north.

One EMU of charge is equal to 2.99792458e+10 ESUS of charge. CONVERSELY, one ESU of charge is equal to 3.335640952e-11 EMUs of chargeExplanation:hop it HELPS ☺️☺️please mark as the brainliest ☺️

Your ANSWER is 60 km/min < 12m/s <18km/hr <180m/minExplanation:FIRST CONVERT all speeds into m/s or km/h or km/mini will convert to m/s 18km/hr = 18×5/18= 5m/s [5/18 BCOZ it is an TRICK to convert km/hr into m/s]12m/s = 12m/s180 m/min = 180/60 = 3m/s4. 60 km/min= 60000/60 = 1000m/splease mark the brainliest

Total internal reflection, in physics, complete reflection of a RAY of light WITHIN a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is GREATER than a CERTAIN limiting angle, called the critical angle.

Uniform Motion:Definition: This type of motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, IRRESPECTIVE of the duration of the time.If a body is involved in rectilinear motion and the motion is consistent, then the acceleration of the body must be zero.Example of Uniform Motion:If the speed of a car is 10 m/s, it means that the car covers 10 meters in one second. The speed is constant in every second.Movement of blades of a ceiling fan.Non Uniform Motion:Definition: This type of motion is defined as the motion of an object in which the object travels with VARIED speed and it does not cover same distance in equal time intervals, irrespective of the time interval duration.Explanation:HOPE it's helpful plzz mark as BRAINLIEST...

charge particles indeed attract uncharged ONES. The negatively charged body can be thought to be an electron rich SPECIE. When brought NEAR the uncharged body, it repels the free electrons from the uncharged body towards its farther END. Plz plz plz mark as BRAINLIST!!!!!
