How is elastic potential energy stored and released in the elastic cord or spring in it is sun lounger

Answer:

Sedimentary rocks.

Explanation:

A rock cycle can be defined as a concept used to describe the continuous process that leads to a rock's creation, formation, transformation from one form to another, destruction and reformation over a specific period of time. The natural phenomenons that influences the rock cycle are weathering, plate tectonic activity, erosion, etc.

A fossil can be defined as the mineral impression or remains of living organisms such as plants and animals that are prehistoric in nature.

Basically, the three (3) main types of rocks are; igneous rock, sedimentary rock and metamorphic rock.

Sediments come from living organisms such as plants to form organic sedimentary rocks and they are usually formed at pressure and temperature that doesn't destroy the fossils contained therein. Organic sedimentary rocks includes chalk, fossiliferous, coal, diatomite, etc. Also, some examples of inorganic land-derived sedimentary rocks are conglomerate, brescia and sandstone.

Hence, an organic sedimentary rock is a type of rock that contains or comprises of fossils.

The top ones being parallel gives 1/(1/30 + 1/40) = 120/7 ohms. The rightmost path in series gives 30 ohms, and then the parallel pair on the right is 1/(1/50 + 1/30) = 75/4 ohms. I = V/R => 9 / (75/4+120/7) [tex]\approx[/tex] .25A

Answer:

a. -40 kV b. -6.408 fJ c. 2.77 × 10⁶ m/s

Explanation:

a) Change of potential for this displacement (A =» B)?

The potential energy change ΔV = -EΔx where E = electric field strength = 8 × 10⁴ V/m and Δx = displacement of charge = 0.5 m

So, ΔV = -EΔx

ΔV = -8 × 10⁴ V/m × 0.5 m

ΔV = -4 × 10⁴ V

ΔV = -40 × 10³ V

ΔV = -40 kV

B) Change of P.E for this displacement (A =» B)?

The change in potential energy ΔU = qΔV where q = proton charge = +1.602 × 10⁻¹⁹ C and ΔV = change in potential = -4 × 10⁴ V

So, ΔU = qΔV

ΔU = +1.602 × 10⁻¹⁹ C × -4 × 10⁴ V

ΔU = -6.408 × 10⁻¹⁵ J

ΔU = -6.408 fJ

C) The speed of proton after the displacement?

From the conservation of energy,

The electric potential energy change of the charge equals its kinetic energy change

ΔK + ΔU = 0

ΔK = -ΔU

ΔK = -(-6.408 × 10⁻¹⁵ J)

K₂ - K₁ = 6.408 × 10⁻¹⁵ J

where K₁ = initial kinetic energy of proton = 0 J (since it starts from rest)

K₂ = final kinetic energy of proton = 1/2mv² where m = mass of proton = 1.673 × 10⁻²⁷ kg and v = speed of proton

K₂ - K₁ = 6.408 × 10⁻¹⁵ J

1/2mv² - 0 = 6.408 × 10⁻¹⁵ J

1/2mv² = 6.408 × 10⁻¹⁵ J

v² = 2(6.408 × 10⁻¹⁵ J)/m

v = √[12.816 × 10⁻¹⁵ J)/1.673 × 10⁻²⁷ kg]

v = √[7.66 × 10¹² J/kg]

v = 2.77 × 10⁶ m/s

Answer:

1. A. Products

2. A. Atoms

3. B. (3)

Explanation:

1. Conservation of Matter states that the reactants have to equal the products.

2. Products and reactants in a balanced chemical reaction have the same number of atoms of each element.

3. Three (3) atoms of carbon would need to be represented.

Number of atoms on the left and on the right side of the balanced chemical reaction is the same, for example: Mg + 2HCl → H₂ + MgCl₂. There are two hydrogen atoms, two chlorine atoms and one magnesium atom on both side of chemical reaction.

Answer: Neptune's distance from the Sun is greater than Saturn's.

Explanation:

The sentence that best describes data that would suggest methane is frozen on Neptune is that Neptune's distance from the Sun is greater than Saturn's.

Since Neptune is farther away from the Sun than Saturn, it implies that it has a colder temperature than Saturn and thus would suggest that methane is frozen on Neptune.

Answer:

A. 1.78 m

Explanation:

Given;

initial velocity of the, u = 12 m/s

angle of projection, θ =  30°

the range of the projectile, R = 7.5 m

To obtain the height through which the projectile lands, we must calculate the maximum height reached by the projectile.

[tex]H = \frac{u^2\ sin^2\theta}{2g} \\\\H = \frac{(12)^2\times (sin(30))^2}{2 \times 9.8} \\\\H = \frac{144 \times (0.5)^2}{19.6} \\\\H = 1.84 \ m[/tex]

Therefore, the height is most nearly 1.78 m

Oxide

Explanation:

Ozone and oxygen are oxidising agents

[tex]O _{3} \: \: ozone \\ \\ O _{2} \: \: oxygen[/tex]

Answer:

Oxygen

Explanation:

The name oxidation actually originates from the word oxygen so the question answers it's self.

In case you don't know what oxidation is:

Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction. When oxidation occurs, the oxidation state of the chemical species increases. Oxidation doesn't necessarily involve oxygen! Originally, the term was used when oxygen caused electron loss in a reaction.

Answer:

P = 120 W

Explanation:

Force required to lift the book, F = 180 N

It is lifted 1 m above the floor in 1.5 s

We need to find the power of the student. Power is equal to work done divided by time taken. So,

[tex]P=\dfrac{Fd}{t}\\\\P=\dfrac{180\times 1}{1.5}\\\\P=120\ W[/tex]

So, the required power is equal to 120 W.

Answer:

F = 1 N

Explanation:

Given that,

The weight of an Apple, W = 1 N

We need to find the net force acting on the apple when it is in free fall. We know that, the force acting on an object under free fall is equal to its weight. So,

F = W = 1 N

Hence, the net force acting on the Apple is 1 N.

Answer:

Object B has greater density

desity A=20/10=2 g cm^-3 . density B=50/10=5 g cm^-3

the object that has greater mass has the greater density because the volume of the those two objects are same

(A) It will 100 times larger than the original force.

As the square of the distance between the two charges increases, the force's strength decreases. Because of this, if the gap between the two charges is doubled, the attraction or repulsion between them weakens and drops to one-fourth of its initial strength. Thus, option A is correct.

As their separation rises, so does the force of attraction or repulsion between two objects.  Additionally, when the spacing between things gets smaller, the force of attraction or repulsion between the objects gets stronger. Distance affects electrical forces significantly.

Gravitational forces will be reduced as separation distance increases because they are inversely proportional to the square of the distance between the two interacting objects. When two things are moved apart, their gravitational attraction to one another also lessens.

Therefore, The new force will be 100 times more than the original.

Answer:

H₀ = 1.6 x 10⁻¹⁸ s⁻¹

Explanation:

The Hubble's Constant can be found by the following formula:

[tex]v = H_o D\\\\H_o = \frac{v}{D}[/tex]

where,

H₀ = Hubble's Constant = ?

v = speed of galaxy = 30000 km/s = 3 x 10⁷ m/s

D = Distacance = 600 Mpc = (6 x 10⁸ pc)(3.086 x 10¹⁶ m/1 pc)

D = 18.52 x 10²⁴ m

Therefore,

The measuring sensitivity of liquid-in-glass thermometers increases with the amount of liquid in the thermometer. The more liquid there is, the more liquid will expand and rise in the glass tube. For this reason, liquid thermometers have a reservoir to increase the amount of liquid in the thermometer.
