Answer: D. movement of material along a coast by waves that approach at an angle to the shore.
Explanation:
Longshore drift is also referred to as the littoral druft and it means the sediment that is moved by the longshore current.
Longshore drift is the movement of material along a coast by waves which approach at an angle to the shore but then recede down the beach.
Therefore, the correct option is D.
Answer:
Explanation:
Function of Aquatic Plants. ... The production of oxygen through photosynthesis-they oxygenate the water via plant processes. Providing underwater cover for fish, amphibians, birds, insects and many other organisms. Providing a surface for algae and bacteria to adhere to.
If the applied force is in the same direction as the object's displacement, the work done on the object is:
W = Fd
W = work, F = force, d = displacement
Given values:
F = 45N
d = 12m
Plug in and solve for W:
W = 45(12)
W = 540J
Answer:
The heat capacity of a sample is 37.7 J/K.
Explanation:
Given that,
Submerged temperature of tissue sample = 275 K
Mass of liquid nitrogen= 2 kg
Temperature = 70 K
Final temperature = 75 K
We need to calculate the heat
Using formula of heat
Put the value into the formula
We need to calculate the heat capacity of a sample
Using formula of heat capacity
Put the value into the formula
Hence, The heat capacity of a sample is 37.7 J/K.
Answer:
Big Dipper, Little Dipper, Cassiopeia, Cepheus
Explanation:
In this region, the above constellations are circumpolar. This means that they appear above the horizon at all times. These are only visible all rear round for people living in Canada and Northern United States.
Circumpolar constellations are constellations that never appear below the horizon when seen from a particular location on planet Earth. Furthermore, these constellations can be seen all year while others are only seen at specific times during the year; thus they are known as seasonal constellations.
Five northern constellations are visible from most locations that are north of the equator. These are Cassiopeia, Cepheus, Draco, Ursa Major, and Ursa Minor.
Note that Ursa Major is often confused with the Big Dipper. While the Little Dipper (which is much fainter) is found in the Ursa Minor constellation. Cassiopeia can be recognized due to its W shape which is quite prominent.
