    vector nature of forces
    Hello I am having some troubles with the following question I am a beginner to physics and have ebeen trying to figure this out. If someone could give me the steps to follow it would be great. The question is as follows:

    A surfer "hangs ten" and accerlates down the sloping face of a wave if the surfs accerlation is 3.25 m/s^2 AND FRICTIOn CAN BE IGNORED what is the angle at which the face of the wave is inclined above the horzontal.

    :confused: :( :mad:

    Draw a right angled triangle (The hypotenuse is the downwards weight of the surfer (mg), the adjacent edge is the component of his force parallel to the wave (3.25m))

    If the hypotenuse is 9.8m and the adjacent edge is 3.25m, what is the angle? (where m is the surfer's mass)

Okay, I just want to know when does a submarine experience greater buoyant force? Is it when it is near the surface of the ocean or near the ocean floor, considering gravity is the same for both situations.

Earthquakes and tidal forces [ 2 Answers ]

There have recently been two large earthquakes in California and Iran. They occurred at a time when Earth was close to perihelion. It was also close to a New Moon. Could there be a connection? Is there any correlation between earthquakes and astronomical movements?
