noname [10]3 years ago
6 0
The correct choice is
B. rises toward the ceiling
<span>In fact, the warmest air is also the air with least density: in warm air, the particles move faster, so the distance between them is larger, on average. Therefore, the warmest air is less dense, and because of that it tends to flow upwards (due to Archimede's principle) and it is replaced by the colder air, creating the so-called convection current.</span>

1. James drives 400 km in 5 hours to his grandmothers. What are the units for speed going to be?
Airida [17]

Answer:

See the answer below

Explanation:

1. Speed is calculated as the ratio of distance and time. Hence, Jame's speed can be calculated as:

       400/5 km/hr = 80 km/hr

The unit for the speed would be km/hr. This can also be converted to m/s:

80 km = 80,000 m

1 hr = 3,600 s

80 km/hr = 80,000/3600 m/s = 22.22 m/s

2. Since James drove 400 km in 5 hours, the distance he drove is 400 km.

3. The time it took for James to get there is 5 hours.
