A ball is thrown vertically upward from the top of a 100 foot tower, with an initial velocity of 10 ft/sec. Its position functio
yan [13]

All you need to know is that velocity is the derivative with respect to time of position.

Therefore: ds/dt = -32t +10

To know the velocity at t=2s you just need to plug t=2 for t in the equation above.

You just tested the hypothesis a proposed model for the position of bright fringes produced by two slits. Explain what the model
Viefleur [7K]

Answer:

two-slit interference model was proposed by Young     d sin θ = m λ

Explanation:

The two-slit interference model was proposed by Young, it establishes that if a coherent source of light passes through two slits, the shape of the given pattern is a consequence of the relative phase difference between the two rays; mathematically it can be expressed by

           d sin θ = m λ

          m= 0, 1, 2, 3, ...

for constructive interference, that is, the two rays arrive with a number between wavelengths.

D is the distance between the slits, tea the angle between the two rays, m an integer and m the wavelength used.

In a simulation a pattern of slits of equal intensity and equally spaced is observed.

Are wind-driven currents found near the surface of the oceans or in the deep waters of the ocean?
drek231 [11]

Wind-driven currents are found NEAR THE SURFACE of the oceans

Explanation:

Surface currents are at the interphase between the hydrosphere and atmosphere. Therefore the feel the greatest effect of drag by wind currents, especially prevailing winds (that blow predominantly in one direction like westerlies and easterlies) within the lower atmosphere.  The deep currents, on the other hand, are more influenced by Coriolis effect of the earth’s rotation. It is these differences in influences of surface and deeper currents that cause Ekman transport in oceans.
