What do u need help with?
Answer:
For aquatic ecosystems, these factors include light levels, water flow rate, temperature, dissolved oxygen, acidity (pH), salinity and depth. Light level is an important factor in aquatic ecosystems.
Solid:
•Has a definite shape and volume.
•It has the lowest energy.
•These are hard to compress.
Liquid:
•Has a definite volume, but take the shape of the container.
•It has medium energy.
•You can compress them a little difficulty.
Gas:
•Has no definite shape or volume.
•They have the highest energy.
•These are easily compressible.
Answer:
M.E = 5880 J
Explanation:
Given data:
Mass = 60 Kg
Height = 10 m
Mechanical energy = ?
Solution:
Formula:
M.E = K.F + P.E
K.E = 1/2 × mv²
P.E = mgh
Diver is not moving so K.E will be zero.
M.E = mgh
M.E = 60 kg × 9.8 m/s² × 10 m
M.E = 5880 J ( j= kg m²/s²)
