Answer:

$\frac{dAB}{dt} = = 50 miles/ hour$

Explanation:

let A represent me and B represent my friend

A speed $\frac{dOA}{dt}$ =30 m/hr toward west

B speed $\frac{dOB}{dt}$ =40 m/hr toward south

after 1/2 hr

total distance cover by A =1/2 * 30 miles = 15 miles

total distance by B = 1/2*40 miles = 20 miles

now from figure

$AB = \sqrt{(15^2+20^2)} = 25 miles$

$AB^2 =OA^2+ OB^2$

Differentiate above equation

$2AB\frac{dAB}{dt} = 2OA\frac{dOA}{dt} +2OB\frac{dOB}{dt}$

$25*\frac{dAB}{dt} = 15*30 +20*40$

$\frac{dAB}{dt} = \frac{1250}{25}$

$\frac{dAB}{dt} = = 50 miles/ hour$

svp [43]

Answer:

625 piece.

Explanation:

Let n be the required no of piece

200 litre = 200 x 10⁻³ m³ = 200 x 10⁻³ x 10³ kg = 200 Kg

mass of ice piece = n x 30 x /1000

Heat lost by ice pieces = (n x 30) / 1000 x ( 80 + 1 x 16⁰C)

Heat gained by water = 200 x 1 x 9⁰C

Heat lost = Heat gained

(n x 30) /1000 x ( 80 + 16 ) =200 x 9

2.88 n = 1800

n = 625
