Answer:
8.67807 N
34.7123 N
Explanation:
m = Mass of shark = 92 kg
= Density of seawater = 1030 kg/m³
= Density of freshwater = 1000 kg/m³
= Density of shark = 1040 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
Net force on the fin is (seawater)
The lift force required in seawater is 8.67807 N
Net force on the fin is (freshwater)
The lift force required in a river is 34.7123 N
Answer: Easy it's 20 miles per second
Explanation:
500 ÷ 25 is equal to 20 miles per second aka 20 × 25 is equal to 500.
Answer:
Vaporization.
Explanation:
When we heat or raise the energy of any sample, it evaporates. Evaporation is known as a form of Vaporization. When some sample evaporates, then they basically take in heat and when the sample condenses, it cools down by giving out the heat into the surrounding, atmosphere and the energy goes into the atmosphere.
An example of evaporation is the rain cycle. Where it's cooler, water on earth's surface evaporates and travels up through the atmosphere. The cool temperature causing the vapor to condense and back into water drops. When the cloud becomes saturated, the droplets fall to the ground in the form of rain.
