Answer:
d = 4180.3m
wavelengt of sound is 0.251m
Explanation:
Given that
frequency of the sound is 5920 Hz
v=1485m/s
t=5.63s
let d represent distance from the vessel to the ocean bottom.
an echo travels a distance equivalent to 2d, that is to and fro after it reflects from the obstacle.
wavelengt of sound is 
= v/f
= (1485)/(5920)
= 0.251 m
Answer:
The cell membrane is capable of transforming oxygen and glucose into energy for the cell
Explanation:
The cell membrane encapsulates all the organelles of the cell. It provides protection for the organelles of the cell.
It transports nutrients into the cell and toxic materials out of the cell. It also prevents the entry of harmful materials into the cell.
The cell membrane does not perform the function of transforming oxygen and glucose into energy for the cell.
Answer:
0.084 kg
Explanation:
I = 0.80 N-s (East wards) = 0.80 i N-s
u = 3.8 m/s = - 3.8 i m/s
v = 5.7 m/s = 5.7 i m/s
Let m be the mass of bat.
I = m (v - u)
0.8 i = m ( 5.7 i + 3.8 i)
0.8 i = m x 9.5 i
m = 0.084 kg
The best answer among the following choices would be A) or the first option Scientists want to share measurements data that they can understand.
Answer:
An increase in the air temperature will cause water temperatures to increase as well. As water temperatures increase, water pollution problems will increase, and many aquatic habitats will be negatively affected.
Explanation:
Lower levels of dissolved oxygen due to the inverse relationship that exists between dissolved oxygen and temperature. As the temperature of the water increases, dissolved oxygen levels decrease.
Increases in pathogens, nutrients and invasive species.
Increases in concentrations of some pollutants such as ammonia and pentachlorophenol due to their chemical response to warmer temperatures.
Increase in algal blooms (Photo of algal blooms).
Loss of aquatic species whose survival and breeding are temperature dependent.
Change in the abundance and spatial distribution of coastal and marine species and decline in populations of some species.
Increased rates of evapotranspiration from waterbodies, resulting in shrinking of some waterbodies such as the Great Lakes.
