Answer:
Velocity = 12 km/h
Explanation:
Velocity can be defined as the division between distance traveled and the time it took for that distance to be traveled:
- Velocity = Distance / Time
With the above information in mind, we can calculate the velocity of the bicycle:
Thus the velocity of the bicycle is 12 kilometers per hour.
Answer:
4180J
Explanation:
(25.0g)(4.184J/g°C)(75°C-35.0°C)
(25.0g)(40.0°C)(4.184J/g°C)
(1.00*10³g°C)(4.184J/g°C) = 4184J
use sig figs:
4180J
