Question

what will be the velocity when time is given 5 min and distance is is 1240 m .
in a.) km/h.
b.)m/s .​

Answer 1

Answer:

Explanation:

Since delta n means change in concentration ofproducts-change in concentration of reactants therefore delta n =1-0=1we must consider only gases only

H - nRT = E 176000 - 1 * 8.314 * 1240 = E 165690.64 J =E 165.6 J

hope it helps u............

please give me brainlist please

Answer 2

Answer:

v = 14.88 km/hr

Explanation:

we know that,

velocity = distance/time

v = d/t

Now,

d = 1240 m = 1.24 km

t = 5 min. = (5/60) hrs = (1/12) hrs

(Remember either distance should be in kilometres and time should be in hours for km/h or distance must be in metres and time should be in hours for m/s, but I took hrs because it would give a whole number.)

v = 1.24/(1/12) = 1.24 × 12

v = 14.88 km/hr

Hope it helped and you understood it........All the best
