Answer:
Volume = 24 cm^3
Explanation:
We recall that the volume of the box is calculated via the formula:
Volume = length * height * width
and that in a product, the number of significant figures for the result should coincide with the number of significant figures of the factor that has the least of them.
In this case, all measures have the same number of significant figures: two. so we calculate the product, and then limit the answer value to exactly two significant figures:
Volume = 4.1 cm * 2.8 cm * 2.1 cm = 24.108 cm^3, which must be rounded to two significant figures as: 24 cm^3
Answer:
When you in a airplane you are in high altitude and thats where air density drops. Thats where ear pops come from.
Explanation:
Explanation:
Average velocity: 6.01×103 m/s.
Velocity at time t=0 s : 0 m/s.
Velocity at t=10 s : 2.40×104 m/s.
Answer:
32.3 m/s
Explanation:
final speed= initial speed + acceleration x time interval
<h3>v = vi + a x t</h3>
where your initial speed is 0 because the truck is resting
a=3.8 m/s2 and t=8.5 s
Power = energy/time=20/4=5.0
