Answer: Option (A) and (D)

Explanation: Isostacy is the gravitational state of equilibrium in which a block sinks down due to the addition of materials and also the same block rises up if materials are eroded.

In terms of our earth, the gravitational force is responsible for the sinking or down-pushing of the continents, and the bouyancy forces in the mantle is responsible for the uplifting of the continents.

MArishka [77]

Answer:

horizontal velocity vh = 6*cos(30°) = 6*(√3)/2 = 3√3 m/s

initial vertical velocity vv = 6*sin(30°) = 6/2 = 3m/s

Using s = ut + at2/2 for change in vertical distance in time t, with acceleration a (-9.8m/s2) and initial velocity u (vv = 3m/s) we have

0 = 3*t - 9.8*t2/2 or t = 6/9.8 s (ignoring the t = 0 solution, which just represents staying still!).

The horizontal distance in time t is vh*t or 3√3*6/9.8 m

Intensity of a wave is the. (a) Power per unit area (b) Power per unit volume (c) Power per unit time (d) All of the above

aksik [14]

Answer:

Intensity of a wave is Power per unit area.

Explanation:

The intensity of wave is defined as the power per unit area in the direction of motion of wave i.e.

$I=\dfrac{P}{A}$

Also, the intensity of a wave is directly proportional to the square of its amplitude. Let a is the amplitude of a wave. So,

$I\propto a^2$

The SI unit of power is watt and the SI unit of area is m². So, the SI unit of intensity is W/m². Hence, the correct option is (a) "Intensity of a wave is Power per unit area".
