Answer:
Mass, m = 0.06 kg
Explanation:
It is given that,
Heat absorbed by copper object is 1386 J
Initial temperature,
Final temperature,
Specific heat of copper, c = 385 J/kg C
We need to find the mass of the copper. The formula of specific heat is given by :
m is mass of copper
So, the mass of the copper is 0.06 kg.
Answer:
1675.51608191 km/h
1041.12001312 mph
Explanation:
r = Radius of Earth = 6400 km
t = Time taken = 24 hours
Velocity is given by
Converting to mile per hour
The speed is 1675.51608191 km/h or 1041.12001312 mph
The direction would be the opposite of the Earth's rotation
So, the direction is East to West
