Answer:
1.8 m
Explanation:
Given: Glass falls from a table, smashes 0.6 seconds later
To find: How high a table is
Formula: Vv=gt, dv=1/2gt^2, t=2d/g
Solution: A table's <em>height</em> is measured from the top of the edge down to the floor. The tables are shown both have a height of 30 inches, which is common for many tables.
<u>Data</u>
- t = 0.6s
- g = 9.81 m/s²
- d = ?
<u>Equation</u>
- d =
²
<u>Math & Units</u>
- d = 4.905 (0.6²)
- d = 442.676
Hence the table is 1.8 m high
Answer:
442.36038 m or 1451.31362 ft
Explanation:
= Initial pressure = 30.15 inHg
= Final pressure = 28.607 inHg
= Density of air = 0.075 lb/ft³
Density of mercury = 13560 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
Difference in pressure is given by
The height of the building is 442.36038 m or 1451.31362 ft
