At which point is the water table closest to the surface? Explain.
dangina [55]

The point is the water table closest to the surface in valleys.

In areas of topographic relief, the water table generally follows the surface but tends to approach it in valleys and intersect the surface with streams and lakes. Closest to the surface is the vented zone where the interstices between the soil are filled with both air and water. Below this layer is a saturation zone where the gaps are filled with water.

The water table is the subsurface boundary between the soil surface and the area where groundwater saturates the space between sediment and rock fissures. At this boundary, water pressure equals atmospheric pressure. The top surface of the groundwater is the groundwater table. Beneath this surface, all pore spaces and cracks in sediments and rocks are completely filled and saturated with water. Groundwater occurs in these saturated layers known as saturation zones or water vapor zones.

What is your weight on Venus, assuming that the acceleration due to gravity on Venus is 8.875 m/s^2 and your mass is 50 kg.
Volgvan

Answer:

Weight on Venus = 443.75 N

Explanation:

Weight of a body is the product of mass and acceleration due to gravity.

So we have

       Weight =  Mass x Acceleration due to gravity

        W = mg

        Mass, m = 50 kg

        Acceleration due to gravity, g = 8.875 m/s²

        W = 50 x 8.875 = 443.75 N

Weight on Venus = 443.75 N

How much current is drawn by a television with a resistance of 30 ω that is connected across a potential difference of 120v?
melomori [17]

By using the Ohms law, we can calculate the current.

Ohms law,

 \frac{V}{I}  = R

Here, V is potential difference, and R is the resistance.

Given,  V=120 V and R = 30 ohm.

Therefore, putting the given values in above relation , we get

\frac{120V}{I} = 30 ohm

or          I=\frac{120}{30} = 4 A

Thus, the current is drawn by a television 4 Ampere
