B. they both involve wave interaction.
I,think potential energy is mgh so 65*100*9,81
Answer:
Biodiversity.
Explanation:
The number of different species in a particular area is known as biodiversity. Blue whales, plants, different kind of animals, and micro-organism living in an ocean is the example of biodiversity. In biodiversity each specie has its own role. For example, if a biodiversity has large number of plants (species), it will have many type of crops.
Answer:
C. Sink until it reaches equilibrium and then remain at a constant depth.
Explanation:
An object immersed in a fluid experiences buoyant force. If the net buoyant force is greater than the net weigh of the object, the object will float.
If the net buoyant force is less than the net wight of the object, it will sink until a depth where the total weight of the object and the force due to the fluid above the object equals the net buoyant force at the bottom of the object (equilibrium), then the object remains at a constant depth.
Answer:
Explanation:
mass of airplane, m = 12000 kg
altitude, h = 10 km = 10,000 m
velocity, v = 175 m/s
(a) Angular momentum
L = m x v x h x Sin 90
L = 12000 x 10,000 x 175
L = 2.1 x 10^10 kg m^2/s
(b) As there is no external torque, so the angular momentum remains constant.
