Answer:
D. Hotel 3 because they will experience beach erosion
Explanation:
A beach groin is a man made structure which is used to protect the beach from sand erosion. It makes the water current to deviate in the other direction thus preventing the beach in the groin area to be eroded.
In the context, constructing a groin by Hotel 2 will prevent beach erosion in its area but this will lead to the soil erosion for the beach in front of hotel 3, thus affecting hotel 3. So Hotel 3 can sue Hotel 2 and stop the groin being constructed by the Hotel 2.
Hence the correct option is (D).
Answer:c>a>b
Explanation:
Given
All the engine extracts same amount of heat(Q) from High-temperature reservoir
For a) 400 and 500 K
For b)500 K and 600K
For c) 400 K and 600 K
So c will give the highest amount of work
c>a>b
The cannon is much heavier than the cannonball, so it has the same momentum, but not the same velocity. The cannonball has less mass to overcome, so it accelerates more quickly.
Let FAB, be the force exerted on body B by body A and FBA be the force exerted by body B on A. Suppose that due to these forces FAB and FBA, dp1/dt and dp2/dt be the rate of the change of momentum of these bodies respectively.
