Fossils are formed in a number of different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.

hope it helps ☺️✌️

Answer:

over years of being underground the pressure causes the organism to press into the rock and form a mold. this mold is the fossil and are found in sedimentary rock

Answer:

20 gram of H as the greastest volume

Explanation:

Each gas sample has the same temperature and pressure. which sample occupies the greatest volume? each gas sample has the same temperature and pressure. which sample occupies the greatest volume? 40.0 gar 20.0 gne 20.0 gh2 4.0 ghe

Given that,

40.0 g of Ar

20.0 g of Ne

20.0 g of h

24.0 g of he

The ideal gas equation ; Pv = nRT

where P is the pressure, V is the volume, R is the gas constant, T is the temperature, n is the number of mole

which is equal to

n = m / M

where m is the given mass

M is the molar mass

The given gas sample are at the same temperature and pressure,

So, the temperature, pressure and gas constant are fixed.

Therefore the volume is proportional to the given mass and molar mass

V ∝ m/M

Substitute the given mass and molar mass of given masses for comparison

No of mole of Ar = mass / molar mass

= 40 / 40 = 1 mole

No of mole of Ne = mass / molar mass

= 20 / 20 = 1 mole

No of mole of h = mass / molar mass

= 20 / 1 = 20 mole

No of mole of he = mass / molar mass

= 24 / 4 = 6 mole

Hence, 20 gram of H as the greastest volume

Answer:The frequency of the echo is slightly decreased

Explanation:

Given

speed of boat [tex]=30\ mph[/tex]

cliff is [tex]3000\ m[/tex] away

when boat is still , suppose t is the time taken by the echo to reach observer on the boat

But as soon as boat starts moving  the distance between cliff and boat decreasing and time for echo to reach observer also decreases

and we know [tex]time \propto \frac{1}{frequency}[/tex]

therefore frequency of the echo slightly decreased.

Answer:

4800

Explanation:

The change in velocity of the car is 17-13=4m/s. Since the change in momentum is the mass multiplied by the change in velocity, the answer is 4*1200=4800. Hope this helps!

Given:

Mass,

Change in velocity,

            =  4 m/s

Now,

The change in momentum is:

= [tex]Mass\times Change \ in \ velocity[/tex]

= [tex]1200\times 4[/tex]

= [tex]4800[/tex]

Answer:

An 8 kg sled mass moves in a straight line on a surface without horizontal friction at a certain point its speed is 4 m / s 2.50 m later its speed is 6 m / s using the work and energy theorem, determine the force acting on the sled assuming it is constant and acts in the direction of the sled movement

The force acting on the 8 kg sled has a value of 32 N.

Explanation:

We have initially look for the work that is applied to the sled, and this will be nothing more than the difference in kinetic energy from the end point to the initial, then:

ΔEc = Ec₂ - Ec₁

ΔEc = 0.5 * m * [V₂² - V₁²]

ΔEc = 0.5* 8 kg * [(6m / s) ² - (4m / s) ²]

ΔEc = 80 J

So, the work is 80 J, now we know that work is a relation distance and force , such that:

W = F * d

F = W / d

F = (80 J) / (2.50 m)

F = 32 N

Therefore, the force acting on the sled is 32 N.

Answer:

When you have two materials with the same index of refraction, it means that if they are touched by a ray of light it won't have a chance, and its form would prevail.

Explanation:

The reason behind this is that in the first place. When light passes through an object of certain refraction it is modified from its natural state, allowing it to change in color to the human eye or many other effects in other perceptive elements. However, when the same light passes through two objects with the same refraction due to their physical characteristics, it doesn't change because once it comes out of the first one it will suffer the same effect from the last one. For it to change the refraction would have to be higher or lower. Then it would be modified. The reason is because the dimensions are not modified. Because at some point the ray of light has to come out of the first one to enter the second one.

Answer:

46°C

Explanation:

q = mCΔT

336,000 J = (20 kg) (4200 J/kg/°C) (50°C − T)

T = 46°C

Becky takes a shower, and he uses 20,000 g of water with specific heat of 4200 J/kg then the starting temperature of the water will be equal to 46 °C.

Specific heat is the amount of energy needed to raise a product's temperature by one degree Celsius per gram. Traditionally, the units of heat capacity are calorie or joules per gram per degree Celsius. The specific heat of water, for instance, is 1 calorie (or 4.186 joules) per gram per degree Celsius.

In the 18th century, the Scottish scientist Joseph Black noted that equivalent masses of various substances required varying quantities of heat to increase them across the same ambient temperature. Based on this discovery, he developed the theory of specific heat.

From the given data in the question,

q = mCΔT

Here ΔT is the change in the temperature.

336,000 J = (20 kg) × (4200) × (50 °C − T)

T = 46 °C

Therefore, the starting temperature of the water is 46 °C.

6C

The quantity of charge, Q, passing through an electric circuit is dependent on the electric current, I, and the time taken, t, for the current to flow. It is given mathematically as follows

Q = I x t          ------------------------------(i)

Where;

I is measured in Amperes(A)

t is measured in seconds (s)

Q is measure in coulombs (C)

From the question,

I = 3A

t = 2s

Substitute these values into equation (i) as follows;

Q = 3 x 2

Q = 6C

Therefore, the number of coulombs of charge that will pass is 6C

Answer:

Each of the pieces will have one north pole and one south pole.

Explanation:

A magnet is made up two ends, one end is known as north pole while the other end is known as south pole.

When a magnet is cut into unequal size pieces, each of the piece will have two ends, one end of each piece is known as north pole while the other end will be south pole.

Therefore, each of the pieces will have one north pole and one south pole.

Answer:

Because you stand at a distance from the mirror at which your entire body shows.

Explanation:

Since the mirror is a plain mirror, the distance of the object from the mirror is also the distance of the image from the mirror. Also since the magnification is 1 for a plane mirror because the height of the image equals the height of the object. Since the magnification always equals 1, for you to be able to see your entire body, you must stand at a distance from the mirror such that your height equals the image height.

Answer: By keeping a distance away from the mirror.

Explanation:

If it's a plane mirror, it's possible to see your entire body by keeping distance away from the mirror. The distance of the object away from the mirror is equal to the distance of the image away from the mirror.

Eventually when the cloud becomes saturated precipitation falls from them(precipitation is moisture in any form that falls from the atmosphere).

Answer:

T = 2.82 seconds.

The frequency [tex]\mathbf{f = 0.36 \ Hz}[/tex]

Amplitude A = 25.5 cm

The maximum speed of the glider is [tex]\mathbf{v = 56.87 \ rad/s}[/tex]

Explanation:

Given that:

the time taken for 11 oscillations is 31 seconds ;

SO, the time taken for one oscillation is :

[tex]T = \frac{31}{11}[/tex]

T = 2.82 seconds.

The formula for calculating frequency can be expressed as :

[tex]f = \frac{1}{T}[/tex]

[tex]f = \frac{1}{2.82}[/tex]

[tex]\mathbf{f = 0.36 \ Hz}[/tex]

The amplitude is determined by using the formula:

[tex]A = \frac{d}{2}[/tex]

The limits that the spring makes the oscillations are from 10 cm to 61 cm.

The distance of the glider is, d = (61 - 10 )cm = 51 cm

Replacing 51 for d in the above equation

[tex]A = \frac{51}{2}[/tex]

A = 25.5 cm

The maximum speed of the glider is:

[tex]v = A \omega[/tex]

where ;

[tex]\omega = \frac{2 \pi}{T}[/tex]

[tex]\omega = \frac{2 \pi}{2.82}[/tex]

[tex]\omega = 2.23 \ rad/s[/tex]

[tex]v = A \omega[/tex]

[tex]v = 25.5 *2.23[/tex]

[tex]\mathbf{v = 56.87 \ rad/s}[/tex]
