Initial reading = 24803 km

Final reading = 25118 km

The speedometer reading at the start of the journey and at the end of the journey was noted by Kamini and the total time was also noted, the average speed is given by,

Total time = 4 hr and 40 min

{tex}Average \ speed = \frac {Total \ distance}{Total \ time}{/tex}

Total distance = Final reading – Initial reading

Total distance = 25118 – 24803

Total distance = 315 km

Total time = 4 hr 40 min

{tex}Total\ time = 4hr + (\frac {40}{60}) hr{/tex}

Total time = 4.67 hr

{tex}Average \ speed = \frac {315}{4.67}{/tex}

Average speed = 67.45 km/hr

Wet Clothes do not dry easily on a rainy day because the air has a lot of water vapour on it and it cannot accommodate the water vapour created by the wet clothes so the water remains in the clothes for a longer time.
The rate of evaporation depends on the temperature weather and humidity. The rate of evaporation is faster in sunny days when temperature is hot and humidity is less.
On the rainy day the temperature and weather is not hot hence the rate of evaporation is slow and wet clothes take longer time to dry up.

Om Dwived 4 years, 6 months ago (6334391)

Because the rainy clouds blocks th sun rays that's why the wet cloths do not dry easily

Anmol Preet 4 years, 7 months ago (9915807)

In a rainy day, the humidity level in the atmosphere is already high. As a result, it will be quite difficult for the moisture associated with wet clothes to change into vapours. Therefore, they will remain wet.

External memory typically refers to storage in an external hard drive or on the Internet. The main “memory” in the computer is the computer work-space, not its storage facility.

External memory which is sometimes called backing store or secondary memory, allows the permanent storage of large quantities of data. Some method of magnetic recording on magnetic disks or tapes is most commonly used

The capacity of external memory is high, usually measured in hundreds of megabytes or even in gigabytes

The most common form of external memory is a hard disc which is permanently installed in the computer and will typically have a capacity of hundreds of megabytes

unlock 35 lakh questions What's your doubt? 10th >Maths >Real Numbers >Revisiting Irrational Numbers >Prove that √(3) + √(5) is... Maths Bookmark Prove that 3 + 5 is irrational. Easy share Share Answer To prove : 3 + 5 is irrational. Let us assume it to be a rational number. Rational numbers are the ones that can be expressed in q p form where p,q are integers and q isn't equal to zero. 3 + 5 = q p 3 = q p − 5 squaring on both sides, 3= q 2 p 2 −2. 5 ( q p )+5 ⇒ q (2 5 p) =5−3+( q 2 p 2 ) ⇒ q (2 5 p) = q 2 2q 2 −p 2 ⇒ 5 = q 2 2q 2 −p 2 . 2p q ⇒ 5 = 2pq (2q 2 −p 2 ) As p and q are integers RHS is also rational. As RHS is rational LHS is also rational i.e 5 is rational. But this contradicts the fact that 5 is irrational. This contradiction arose because of our false assumption. so, 3 + 5 irrational.
