Explain how and why water travels through the four Earth systems as it moves through the water cycle

1 answer:

6 0

Water in the Earth system is influencing all aspects of life on Earth. ... The returning water falls directly back into the oceans, or onto land as snow or rain. It soaks into the soil to move into the groundwater or runs off the Earth's surface in streams, rivers and lakes, which drain back into the oceans.

A block mass m (0.25 kg) is pressed against (but is not attached to) an ideal spring of force constant k (100 N/m) and negligibl

VMariaS [17]

Answer:

d. All the above choices are correct.

Explanation:

When a spring of spring constant k is compressed by distance x , the potential energy stored in it is equal to

E = 1/2 k x²

If spring constant is 2 k , potential energy stored

E = 1/2 2k x²

= k x²

which is twice the earlier potential energy.

In the first case , the energy of spring is imparted to box . The energy given to box is spent by frictional force due to which box comes to rest.

So energy of box acquired from spring = work done by frictional force.

So energy of box acquired from spring = F X d , F is frictional force , d is displacement .

In the second case ,

energy acquired by box becomes two times

Work done by frictional force will also become two times to put box at rest

So displacement will be two times ( because frictional force is constant )

so option a is correct .

option b is also correct .

Because kinetic energy of box will be twice as explained above .

So option d will be correct.

explain to the guest and learners the procedure and guidelines that are used in making an instrument used to monitor the tempera

Aloiza [94]

In making a thermometer used to monitor the temperature of the water, a glass tube, a scale, and a thermometric liquid such as alcohol is required.

<h3>What is a thermometer?</h3>

A thermometer is an instrument that is used to measure or read the temperature of a body or a substance.

There are different types of thermometers such as:

Liquid-in-glass thermometers
Gas thermometers
Resistance thermometers

A simple liquid-in-glass thermometer consists of the following parts:

A glass tube
A scale
A thermometric liquid such as alcohol

Therefor, in making a thermometer used to monitor the temperature of the water, a glass tube, a scale, and a thermometric liquid such as alcohol is required.

In conclusion, a thermometer is the instrument used in measuring temperature.

An electric car accelerates for 8.0 s by drawing energy from its 320-V battery pack. During this time, 1300 C worth of electrons

kati45 [8]

(a) $8.13\cdot 10^{-21}$

The magnitude of the charge of one electron is

$q=1.6\cdot 10^{-19}C$

Here the total amount of charge that passed through the battery pack is

Q = 1300 C

So this total charge is given by

Q = Nq

where

N is the number of electrons that has moved through the battery

Solving for N,

$N=\frac{Q}{q}=\frac{1300 C}{1.6\cdot 10^{-19} C}=8.13\cdot 10^{-21}$

(b) $4.16\cdot 10^5 J$

First, we can find the current through the battery, which is given by the ratio between the total charge (Q = 1300 C) and the time interval (t = 8.0 s):

$I=\frac{Q}{t}=\frac{1300 C}{8.0 s}=162.5 A$

Now we can find the power, which is given by:

$P=VI$

where

V = 320 V is the voltage

I = 162.5 A is the current

Subsituting,

$P=(320 V)(162.5 A)=52,000 W$

And now we can find the total energy transferred, which is the product between the power and the time:

$E=Pt = (52,000 W)(8.0 s)=4.16\cdot 10^5 J$

(c) 69.7 hp

Now we have to convert the power from Watt to horsepower.

We know that

1 hp = 746 W

So we can set up the following proportion:

1 hp : 746 W = x : 52,000 W

And by solving for x, we find the power in horsepower:

$x=\frac{1 hp \cdot 52,000 W}{746 W}=69.7 hp$

A wire 2.80 m in length carries a current of 5.20 A in a region where a uniform magnetic field has a magnitude of 0.430 T. Calcu

galina1969 [7]

Question:

A wire 2.80 m in length carries a current of 5.20 A in a region where a uniform magnetic field has a magnitude of 0.430 T. Calculate the magnitude of the magnetic force on the wire assuming the following angles between the magnetic field and the current.

(a)60 (b)90 (c)120

Answer:

(a)5.42 N (b)6.26 N (c)5.42 N

Explanation:

From the question

Length of wire (L) = 2.80 m

Current in wire (I) = 5.20 A

Magnetic field (B) = 0.430 T

Angle are different in each part.

The magnetic force is given by

$F=I \times B \times L \times sin(\theta)$
