A bus has velocity of 20 m/s towards east and another bus has velocity of 15 m/s in west direction . if they start to move from
Snezhnost [94]

Answer:

3.8 km

Explanation:

Eastern Side Bus

Velocity = 20m/s

Covers distance in 2 min (120sec) = 20×120 = 2400m = 2 km

Western Side Bus

Velocity = 15m/s

Covers distance in 2 min (120sec) = 15×120 = 1800m = 1.8 km

Separation Distance = 2+1.8 = 3.8 km

Temperature difference in the body. The surface temperature of the body is normally about 7.00 ∘C lower than the internal temper
Nikolay [14]

Answer:

Temperature difference in kelvin =7K

Temperature difference in Fahrenheit degree = 12.6°F

Explanation:

Temperature difference = 7°C

273 is added to the Celsius value to convert to kelvin temperature.However if 273 is added to both the initial and final values of the Celsius temperature values, then the difference still stays the same. Hence the difference in kelvin is 7K.

To convert the temperature difference to Fahrenheit we simply multiply 1.8

=7*1.8 = 12.6°F
