Answer:
when a element of 1 group take part in reaction, its atom looses outer electron and form positively charged ions called Cation.
Explanation:
When hard stabilization structures such as groins are used to stabilize a shoreline, the change in the longshore current results <u>deposition of sediment. </u>
On the upcurrent side of the barrier, sediment is deposited as the longshore current slows.
What is Hard stabilization?
- Hard stabilization is the prevention of erosion through the use of artificial barriers.
- Other hard stabilization structures, such as breakwaters and seawalls, are built parallel to the beach to protect the coast from the force of waves.
- Hard stabilization structures, such as groins, are built at right angles to the shore to prevent the movement of sand down the coast and maintain the beach.
- These constructions are made to last for many years, but because they detract from the visual splendor of the beach, they are not always the ideal answer.
- Additionally, they affect the habitats and breeding sites of native shoreline species, interfering with the ecosystem's natural processes.

Answer:
17.1130952381 s
No
Explanation:
t = Time taken
u = Initial velocity = 115 m/s
v = Final velocity = 0
s = Displacement
a = Acceleration = -6.72 m/s² (negative as it is decelerating)
From the equations of motion
The minimum time required to stop is 17.1130952381 s
The distance that is required for the jet to stop is 0.98400297619 km which is greater than 0.8 km. So, the jet cannot land on a small tropical island airport.
Answer:
The value is 
Explanation:
From the question we are told that
The height of the water is 
The density of oil is 
The height of oil is 
Given that both arms of the tube are open then the pressure on both side is the same
So
=> Here
where 
is the density of water with value 
and 
is the atmospheric pressure
and
=> 
=> 
=> 
=> 
The difference in height is evaluated as
