2 examples of where ground water comes from

AleksAgata [21]

Answer: Example of ground water

Explanation: Groundwater is part of the hydrologic cycle, originating when part of the precipitation that falls on the Earth's surface sinks (infiltrates) through the soil and percolates (seeps) downward to become groundwater.

The density of water is 1000kg/m3 and the density of ice is 900kg/m3. When 0.050 m3 of water is frozen, what will be the new vol

Bingel [31]

Sorry if this answer is a bit late...

We know that the volume of the water is 0.5 cube meters.

The density of water is 1.000 g/m^3 (that's the real density of water... maybe typos?)

The density of ice is 0.900 g/m^3 (that's the approximate density of ice)

First, let's multiply the volume of water by the density of the water to get the mass, since we know that the mass does not change with the ice gets frozen.

0.5 * 1.000 = 0.500 g

Now, let's divide that by the density of ice to get the volume of the ice.

0.500 / 0.900 = 5/9 cube meters

≈ 0.556 cube meters.

The volume of the ice is 5/9 or 0.556 cube meters.

Have an awesome day! :)

Are u god tell me u have to tell me are u a god

Allushta [10]

They tell me I'm a god, I'm lost in the facade

Six-feet off the ground at all times, I think I'm feelin' odd

No matter what I make, they never see mistakes

Makin' so much bread, I don't care that they're just being fake

They tell me they're below me, I act like I'm above

The people blend together but I would be lost without their love

Can you heal me? Have I gained too much?

When you become untouchable, you're unable to touch

Is there a real me? Pop the champagne

It hurts me just to think and I don't do pain

Stayin' still, eyes closed

Let the world just pass me by

Pain pills, nice clothes

If I fall, I think I'll fly

Touch me, Midas

Make me part of your design

None to guide us

I feel fear for the very last time.

A 2.50 gram rectangular object has measurements of 22.0 mm, 13.5 mm, and 12.5 mm. what is the object's density in units of g/ml?

Zinaida [17]

G/mL is equivalent to g/cm^3, so we first convert the dimensions into cm:
2.20 cm, 1.35 cm, and 1.25 cm
Then the total volume is: V = lwh = 3.7125 cm^3
To get the density, we divide mass by volume: 2.50 g / 3.7125 cm^3 = 0.6734 g/cm^3 = 0.6734 g/mL

The acceleration of an object would increase if there was an increase in the

xxMikexx [17]

As per Newton's II law we know that

$F_{net} = ma$

here we know that

$F_{net} = F_{ap} - F_f$

so here we will have

$a = \frac{F_{ap} - F_f}{m}$

so here if we need to increase the acceleration we need to increase the applied force while on increasing the mass or on increasing the friction force the acceleration will decrease.

So here correct answer will be

<em>A) force on the object.</em>
