Answer:
The answer to your question will be d) greater the pressure
Explanation:
Answer:
(a) The density of the object is 316/343 × the density of the oil
(b) The fraction of oil displaced after immersing the object is 0.461 of the oil volume
Explanation:
(a) The volume, V of a cone of height, h and base diameter, D = 2×r is given by the following equation;

The volume of the object is therefore;

Where 6 cm is above the oil level we have;
above the oil level
Therefore, volume of the oil displaced =
cm³ = 216.11 cm³
The density of the object is thus;

The density of the object = 316/343 × the density of the oil.
(b) The volume of the oil = 2 × Volume of the object = 
The fraction of the volume displaced, x, after immersing the object is given as follows;

The fraction of oil displaced after immersing the object = 0.461 of the volume of the oil
Answer:
12 kJ
Explanation:
Given:
v₀ = 0 km/h
a = 5 km/h²
t = 30 min = 0.5 h
Find: v
v = at + v₀
v = (5 km/h²) (0.5 h) + 0 km/h
v = 2.5 km/h
v = 2.5 km/h × (1000 m/km) × (1 h / 3600 s)
v = 0.694 m/s
KE = ½ mv²
KE = ½ (50,000 kg) (0.694 m/s)²
KE = 12,000 J
KE = 12 kJ
Eroded soil can enter streams, causing them to fill up with sediment.
