Erosion and Weathering can cause changes in earths surface but how does erosion alone changes the earth surface.

Answers

Answer:

The action of erosion alone can change the earth's surface. Erosion can wash away nutrients on the earth's surface, change the appearance of the soil of a particular area over time, can bore holes, that form caves, change landscapes for example when the earth is hit with gully erosion by continuous water runoff over time. Erosion can move soil to a new area.

Explanation:

Weathering involves breaking down rock into smaller pieces without any form of formal movement of those broken rock pieces. These processes that can lead to weathering are caused by mechanical, chemical, and organic processes which can happen over time. Erosion can now move broken rock pieces or soil to another place by water or wind. Weathering and erosion constantly change the Earth's surface.

State which is true concerning the objects observed with a 30m telescope, versus a 10m telescope. A) The 30 m telescope can observe objects 30 times fainter, and with 3 times the resolution of the 10 m telescope. B) The 30 m telescope can observe objects with 1/9 the angular diameter, and 9 times fainter than, the 10 m telescope. C) The 30 m telescope can observe objects 9 times fainter, and with 3 times smaller angular size, than the 10 m telescope. D) The 30 m telescope can observe objects 3 times fainter, and with 3 times smaller angular size, compared to the 10 m telescope.

Answers

Answer:

Option C, The 30 m telescope can observe objects 9 times fainter, and with 3 times smaller angular size, than the 10 m telescope.

Explanation:

As we know,

The surface brightness of the object viewed through telescope is proportional to the square of the diameter of the lens

Thus, Brightness ([tex]B_{30}[/tex]) of 30 m telescope would be proportional to [tex]30^2[/tex]

Brightness of 10 m ([tex]B_{10}[/tex]} telescope would be proportional to [tex]10^2[/tex]

Thus, the ration of the two would be

[tex]\frac{B_{30}}{B_{10}} = \frac{30^2}{10^2} \\\frac{B_{30}}{B_{10}} = \frac{9}{1} \\B_{30} = 9 * B_{10}[/tex]

Thus, brightness of 30 m telescope would be able to view 9 times fainter object as compared to the 10 m telescope.

Also , 30 m telescope would be able to view 3 times smaller angular sized object as compared to the 10 m telescope

Hence, option C is correct

Describe the net transfer of thermal energy and any changes in temperature When a metal block at 300Ak is placed in water at 15°C

Answers

Answer:

Q_c = Q_abs

Explanation:

You are asked to describe the process when placing a hot block in cold water.

The first thing to do is put all the quantities in the same units

block temperature      T_bloque = T_h = 300 K = 300 -273 = 27ºC

water temperature     T_water = T_c = 15ºC

* initially the block cools down decreasing its temperature

* the water temperature increases

* the equilibrium is established when the thermal energy of the two bodies is equal, therefore they have the same temperatures T_f

* Conservation of energy requires that the energy released by the hot block is equal to the energy absorbed by the cold body (water)

transferred thermal energy Q_c = m_block ce_block (T_h-T_f)

absorbed thermal energy Q_abs = m_agua ce_agua (T_f - T_c)

* if we subtract the energy transferred and the absorbed gives zero, therefore the net energy transferred is zero

                               Q_c = Q_abs

that gold were made into a thick wire with a cross-sectional area of 1cm2
, its
total resistance would be about 6.60 × 102 Ω. If the same operation were
applied to the gold reserves of Germany, France, and Switzerland, the
resistances would be 2.40 × 102 Ω, 2.00 × 102 Ω, and 2.00 × 102 Ω,
respectively. Now consider all four resistors connected as shown in the circuit
diagram below. Find the equivalent resistance.

Answers

The equivalent resistance of the circuit is 65.98 Ω.

What is Resistor?

A resistor is an electrical component that limits or regulates the flow of electrical current in a circuit. It is designed to provide a specific amount of resistance to the flow of electrons, measured in ohms, and is typically made of a material that can resist the flow of electricity, such as carbon or metal. Resistors are used in a wide range of electronic devices and circuits, from simple LED flashers to complex computer systems.

To find the equivalent resistance of the circuit, we need to use the formula for resistors in parallel:

1/Req = 1/R1 + 1/R2 + 1/R3 + 1/R4

where Req is the equivalent resistance, and R1, R2, R3, and R4 are the resistances of the four resistors.

Substituting the given values, we get:

1/Req = 1/6.60 × 102 + 1/2.40 × 102 + 1/2.00 × 102 + 1/2.00 × 102

1/Req = 0.01515

Req = 65.98 Ω

Therefore, the equivalent resistance of the circuit is 65.98 Ω.

A 0.7 tennis ball is thrown with a velocity of 20 m second to the right what is the momentum of the tennis ball

Answers

Explanation:

Momentum of an object is defined as the product of the mass of object and the velocity with which it is moving.

p = mv

where, p = momentum, m= mass and v= velocity

mass m = 0.7 Kg and v = 20 m/s

p = 0.7×20 = 14 Kg-m/sec

Therefore, momentum of the object  = 14 kg-m

On your first trip to Planet X you happen to take along a 100 g mass, a 40-cm-long spring, a meter stick, and a stopwatch. You're curious about the free-fall acceleration on Planet X, where ordinary tasks seem easier than on earth, but you can't find this information in your Visitor's Guide. One night you suspend the spring from the ceiling in your room and hang the mass from it. You find that the mass stretches the spring by 22.6 cm . You then pull the mass down 10.9 cm and release it. With the stopwatch you find that 10 oscillations take 18.8 s .

Answers

Answer:

[tex]g=2.513m/s^2[/tex]

Explanation:

From the question we are told that:

Mass Taken [tex]m=100g \approx 100*10^{-3}[/tex]

Strain on Spring [tex]l_s=22.6cm \approx 22.6*10^{2}[/tex]

Distance pulled down [tex]d_d=10.9[/tex]

Time for ten oscillations take [tex]t=18.8s[/tex]

 

Generally the equation for angular velocity is mathematically given by

[tex]\omega=2\pi\\\omega=2\pi*\frac{10\ oscillations}{t}\\\\\omega=2\pif=2\pi*\frac{10\ oscillations}{18.8}\\Also\\\omega=\sqrt{\frac{k}{m}} \\\omega=\sqrt{\frac{k}{100*10^{-3}}}[/tex]

Therefore

[tex]{2\pi*\frac{10\ oscillations}{18.8}}=\sqrt{\frac{k}{100*10^{-3}}} \\k=\sqrt{2\pi*\frac{10\ oscillations}{18.8}}*100*10^{-3}\\k=1.112N/m[/tex]  

Generally the equation for Acceleration due to gravity is mathematically given by

[tex]F=mg\\mg=k l_s\\g=\frac{k l_s}{m}\\g=\frac{1.112*2.6*10^{2}}{100*10^{-3}}[/tex]

[tex]g=2.513m/s^2[/tex]

The angular velocity is the ration of the change in the angle turned to time.

Why does the angular velocity increase?

The angular velocity is the ration of the change in the angle turned to time. As such, the angular velocity is measured in radians per second. We have been told that the athlete is supposed to perform the jump between figures 1 and 2 in multiple somersaults.

Each time the athlete somersaults, the angular velocity changes. As such, the rate of change of the angular velocity between figures 1 and 2 would be quite high.

On the other hand, the athlete jumps straight vertically down between figures 2 and 3 and does not turn. Hence, the angular velocity decreases.

Testing shows that a sample of wood from an artifact contains 12.5% of the original amount of carbon-14. Given that the half-life of carbon-14 is 5730 years, how old is the artifact?

A. 22,920 years
B. 17,190 years
C. 11,460 years
D. 5730 years

Answers

Answer:

B. 17,190

Explanation:

got it right, trust

The age of the artifact is 17190 years. So, the correct option is B.

What is meant by half life ?

The amount of time needed for half of a radioactive sample's atomic nuclei to spontaneously decay (transform into another nuclear species by producing particles and energy) is known as the half-life.

Here,

Amount of Carbon-14 present in the given sample = 12.5 %

Given that the half-life of Carbon-14 is 5730 years. That means after a period of 5730 years, the percentage of Carbon-14 present in the sample will be 50% of the original amount.

So, age of the artifact when 50% is present is 5730 years.

Thus, after a period of 2 half-lives, the amount of carbon-14 present will be, 25%.

So, age of the artifact when 25% is present,

t = 2 x 5730 = 11460 years

Therefore, we can say that,

The age of the artifact when 12.5% is present,

t' = 3 x 5730 = 17190 years

Hence,

The age of the artifact is 17190 years. So, the correct option is B.

A gas mixture has 10% O2, 50% Ar (40 gmw) and 40% Pu (244 gmw). What is the density of this mixture?

Answers

Answer: 5.39g/L

Explanation:

We need to calculate the average molar mass of the mixture which will be:

= (10 × 32) + (50 × 40) + (40 × 244) / 100

= (320 + 2000 + 9760) / 100

= 12080 / 100

= 120.8g/mol

Since the volume occupied is 22.4L and 1 mole of the gas will occupies 22.4L given the standard temperature conditions, then the density of the mixture will be:

= Mass / volume

= 120.8 / 22.4

= 5.39g/L

Therefore, the density of the mixture will be 5.39g/L.

What is a parallel and series combination of resistance?

When two or more resistors are connected between two same points, they are said to be connected in parallel combination(as shown in fig).  The equivalent resistance is the reciprocal and the sum of reciprocals of all resistance connected in parallel combination.

[tex]\frac{1}{R_{s}} = \frac{1}{R_{1}} + \frac{1}{R_{2} } + \frac{1}{R_{3}} ..........+ \frac{1}{R_{n} }[/tex]  where Rs is the equivalent or total resistance of the circuit.

In parallel combination, same potential difference exists across each resistor. But current through each resistance is different.

When two or more resistors are connected one after other, they are said to be connected in series as shown in figure. in this combination voltage difference across each resistance is different which is given by ohms law. current flowing through each resistance is same.

equivalent resistance for series combination is given by,

R(s) = R₁ + R₂ + R₃...........+R(n).

In this problem given resistance are not seen, Resistor can be with 41 and 17Ω.

Given,

R₁ = 17 Ω

R₂ = 41 Ω

[tex]R_{s} = ?[/tex]

by parallel combination,

[tex]\frac{1}{R_{s}} = \frac{1}{R_{1} } + \frac{1}{R_{2} }[/tex]

[tex]R_{s} = \frac{R_{1} R_{2} }{R_{1} + R_{2} }= \frac{17*41}{17+41} = \frac{697}{58} = 12[/tex]

R = 12 Ω.
