The answer is:
The water level by rock affected by wave as:
if the direction of the wave is going to the rock naturally by the effect of the tide which comes in, the water level will rise and increase if the wave is escaping or receding the water level will decrease and will be lower.
when the tsunami is a tidal wave which is a series of waves in a water body caused by the displacement of a large volume of water.
It will take at least 3 hours for them to get to Bridgeport
Answer:

Explanation:
Given:
- temperature of skin,

- initial temperature of steam vapour,

- latent heat of steam,

- mass of steam,

- specific heat of water,

- final temperature,

<em>Assuming that no heat is lost in the surrounding.</em>
<u>We know:</u>

<u>Now the total heat given by the steam to form water at the given conditions:</u>
..............................(1)
where:
latent heat given out by vapour to form water of 100°C
heat given by water of 100°C to come at 34°C.
putting respective values in eq. (1)



is the heat transferred to the skin.
Explanation:
the answer is y=strong winds move sand dunes in the desert
Answer:
f = 692 N
Explanation:
given data:
f =800N
a =1.2 m s^{2}
m= 90 kg
from newton's second law
net force 
therefore we have from above equation
ma =F - f
putting all value to get force of friction
1.2*90 = 800 - f
f = 692 N
