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.

You know that you sound better when you sing in the shower. This has to do with the amplification of frequencies that correspond

Lera25 [3.4K]

Answer: Length axis f= 114.3 Hz, Width axis f=228.67 Hz

Explanation:

We are given that,

Length of tub= 1.5 m

Width of tub= 0.75 m

Sound speed= 343 m/s

Now, we are also given shower is closed.

So, frequency is given as:

f= $m* \frac{v}{2L}$

For length axis

Put v= 343 m/s, m=1 and L=1.5 m

f= 1 * $\frac{343}{2*1.5}$

f= 114.3 Hz

For next resonant frequency, m=2

f= 2* $\frac{343}{2*1.5}$

f= 228.67

For width axis

Put v= 343 m/s, m=1 and L= 0.75 m

f= 1* $\frac{343}{2*0.75}$

f= 228.67 Hz

For next frequency, m=2

f= 2* $\frac{343}{2*0.75}$

f= 457.34 Hz

The gravitational field on Saturn is 10.4 times its value on Earth.

nalin [4]

The weight of 100 kg mass on Saturn is 10,192 N.

The weight of 7.0 kg mass on Pluto is 2.01 N.

The given parameters;

acceleration due to gravity, = 10.4g
mass of the Saturn, m = 100 kg
acceleration due to gravity on mercury, = 3.59 m/s²

The weight of 100 kg mass on Saturn is calculated as follows;

W = mg

W = 100 x 10.4 x 9.8

W = 10,192 N

The weight of 7.0 kg mass on Pluto is calculated as follows;

W = 7 x 0.08 x 3.59

W = 2.01 N

Alex is asked to move two boxes of books in contact with each other and resting on a frictionless floor. He decides to move them

Anit [1.1K]

Answer:

2.8 N

Explanation:

Fp = 7.7 N

mA = 12.1 kg

mB = 7 kg

Let a be the acceleration and Fc be the contact force between A and B.

By the free body diagram, use Newton's second law

Fp - Fc = mA x a ..... (1)

Fc = mB x a ..... (2)

Adding both the equations

Fp = (mA + mB) x a

7.7 = (12.1 + 7) x a

a = 0.4 m/s^2

Substitute this value in equation (2), we get

Fc = 7 x 0.4 = 2.8 N

Thus, the contact force between the two blocks is 2.8 N.

An ant crawls 50 cm to the right, stops, and then crawls 30 cm to the left. Calculate the distance that the ant travels, and cal

borishaifa [10]

Answer and Explanation:

If the ant was to crawl 50cm to the right, then come back 30 cm, then the total distance walked would be 80cm.

- Combine 50cm and 30cm to get 80 cm.

For displacement, the answer is 20 cm.

- When calculating displacement, you use the initial (starting) distance. and subtract that from the final distance, giving you the displacement, or the amount traveled from the starting point to the final point if you were to make a straight line from the starting point to end point. (0 to 50, then back 30 the same direction, so subtract 30 from 50 to get 20)

krek1111 [17]

We have that the Throw has changed in distance the ball has traveled and the Force applied in trowing the ball and Possibly the time of travel

From the Question we are told that

You toss a ball to someone one meter away

You toss it to someone four meters away

Generally

When you toss toss a ball to someone one meter away and You toss it to someone four meters away the are things that have changed

Force
Distance

Therefore

The Throw has changed in distance the ball has traveled and the Force applied in trowing the ball and Possibly the time of travel
