Answers
Step-by-step explanation:
a...Mumbai Weather Today (1–3 days) Heavy rain (total 75mm), heaviest during Mon night. Warm (max 29°C on Wed afternoon, min 28°C on Tue night). Winds decreasing (near gales from the SW on Mon afternoon, light winds from the SW by Thu morning).
b....At 12 noon, the temperature = 10° C above zero
The temperature is decreasing at 2° C per hour
8° C below zero = - 8° C
So, total fall in temperature from 10° C to 0° C and from 0° C to - 8° C = 18° C
Since the temperature falls 2° C in every one hour.
Therefore, to decrease 18° C, time taken = 18/2
= 9 hours
Present time is 12 noon so, the time when the temperature is - 8° C
= 12 noon + 9 hours
So, The time at which the temperature will be - 8° C = 9 PM
At 9 PM, the temperature is - 8° C, the temperature at 12 midnight will be =
(- 8° C) + (- 2° C × 3 hours)
= (- 8° C) + (- 6° C)
= - 14° C
So, at 12 midnight the temperature will be - 14° C.
c....At srinagar temperature was -5 degree Celsius on Monday and then it dropped by 2 degree Celsius on Tuesday .
as it dropped by 2 it is -2
=>temperature on tuesday = -5 +(-2)
= -5-2
= -7 celcius
after that on wedneday,it rose 4 degrees
as it rose 4 degrees it is +4
temperature on wedneday = -7 +4
= -3 celcius
