Answer:The pressure of Mercury = 588,600Pa
Explanation:
The pressure of Mercury is given as
p=h x ρ x g
Where h =height= 20 dm
changing to meters
10 decimeters (dm) =1 meter
20dm =2 meter, 2m
ρ is the density =30000-kg/m³
g , gravity = 9.81-m/s²
Pressure = 2.0m x 30000-kg/m³ x 9.81-m/s²
588,600 kg.m/ s²/m² =588,600 N/m²
The pressure of Mercury=588,600Pa
Potatoes need sun, water and soil
Answer:
During Earth's orbit in the summer months, the top of the Earth (the Northern Hemisphere) is tilted toward the sun, giving us longer days. In winter, the Northern Hemisphere points away from the sun, resulting in fewer hours of sunshine and shorter days
