How do coal deposits found in the U.S. and Serbia help prove the theory of continental drift?

Answers

Answer:

Wegner's hypothesis met with wide skepticism, but found support and development in ... theory because Wegener could not satisfactorily explain how the continents moved.

Explanation:

Some of his theory was proven wrong, but he was still correct about his hypothesis. The fossils were part of proof for the theory because some of the fossils were found on shore line. And, some of those animals couldn't swim. So, this is proof that some animals lived on the land. And over time the land drifted apart.

The half-life of cobalt-60 is 5.26 years. If 50 grams are left after 15.78 years, how many grams were in the original sample?

Answers

Answer:

Explanation:

Half life  = 5.6

no of half life in 15.78 years = 15.78 / 5.26

= 3 .

[tex]N = N_0(\frac{1}{2})^n[/tex]

N₀ is original mass , N is mass after n number of half lives.

Inserting the given data in the equation above

[tex]50 = N_0(\frac{1}{2})^3[/tex]

N₀ = 50 x 2³

= 400 gm .

original sample will contain 400 gms of sample.

A 25.2 kg gazelle moving 2.33 m/s
sees a lion, and exerts a 113 N
force to accelerate. How fast is
it moving 2.00 s later?

Answers

Force = mass x acceleration
113N = 25.2a
a = 4.48 m/s^2
Vf = Vi + at
Vf = 2.33 + 4.48(2) = 11.3 m/s

The velocity of the gazelle after 2 seconds is equal to 11.3 m/s.

What is the equation of motion?

The equations of motion have described the relationship between the time, velocity, acceleration, and displacement of a moving object.

The equations of motions can be described as shown below:

[tex]v = u + at\\S = ut +\frac{1}{2}at^2 \\ v^2-u^2 = 2aS[/tex]

Given the mass of the gazelle, m = 25.2 Kg

The force acting to accelerate, F = 113N

The acceleration in the speed of gazelle is given by: a = F/m

a = 113/ 25.2

a = 4.48 m/s²

The initial speed of the gazelle, u = 2.33 m/s

From the first equation of motion we can calculate the final velocity of the  gazelle:

v = u + at

v = 2.33 + (4.48) (2)

v = 11.3 m/s

Therefore, the velocity of the gazelle 2 seconds later is 11.3 m/s.

Read the scenario. A car starts 10 m north of a reference point. It moves at a constant velocity over the next 5 s, reaching a position of 10 m south of the reference point. What is the car’s average velocity? 2 m/s south 4 m/s north 0 m/s 4 m/s south

Answers

Answer:

4 m/s south

Explanation:

This is a pretty easy one.

Assume that the car has a reference point ragged x

We also know that the car starts moving at a point 10 m North of X. It moves steadily at a uniform velocity and ended at a position 10 m south of X.

If x is the reference point, we can infer that the car moves a total distance of, 10 m + 10 m.

Thus, the total distance moved by the car is 20 m.

It is also stated that it achieves that distance in 5 seconds.

Velocity is defined as the ratio of distance with respect to the tome taken, i.e V = d/t

Then, the velocity is

V = 20 / 5 = 4 m/s

Considering the fact that the car left and moved towards the south. We can say that it moved 4 m/s South.

What is the formula for velocity???

Answers

Explanation:

divide the distance by the time it takes to travel that same distance, then add your direction to it.

Or change in displacement divided by change in time.

Two water waves meet at the same point, one having a displacement above equilibrium of 60 cm and the other having a displacement above equilibrium of 80 cm.

Answers

Answer:

The resultant displacement is 140 cm

Explanation:

say first displacement d₁ is 60 cm

and second displacement d₂ is 80 cm

Resultant displacement = d₁ + d₂

= 60 + 80

= 140 cm

Answer:

Explanation:

To solve this problem it will be necessary to apply the interference principle.

Under this principle interference is understood as a phenomenon in which two or more waves overlap to form a resulting wave of greater, lesser or equal amplitude. In this case, if both are at the same point, the result of the total displacement will be the sum of the individual displacements, therefore

[tex]x = \sum h_i\\\\x = 60cm + 80cm\\\\x =140cm[/tex]

Therefore the resulting displacement above equilibrium is 140cm

(a) To find the amount of bean needed by a man you first calculate the equivalence in beans to 2500kJ

[tex]2500kJ*\frac{100g}{1630kJ}=153.37\ g[/tex]

Thus, 153.37 g has the energy needed by a man that needs 200kJ per day.

(b) The amount of energy per pot of bean is given by:

[tex]E=350g*\frac{1630kJ}{100g}\\\\E=5705\ kJ[/tex]

Thus, the energy is 5705kJ

How does visible light interact with objects to produce the colors we see?​

Answers

Answer:

Visible light when all put together is white. When objects appear to be, lets say, red, it would be the only color not absorbed by that object. same goes with all other colors. So black objects absorb all colors (not 100%) and that is why black clothing gets hotter, it simply absorbs all incoming light, as apposed to white that will reflect the colors back, making all of them together appear white. Hope this helps, not the best at explaining things.

El dibujo muestra donde se encuentra un caracol en distintos instantes de tiempo.?Podemos afirmar que se trata de un movimiento acelerado?Razona tu respuesta

Answers

Answer:

if the acceleration is zero the displacements are equal in the same time interval, so we would see the points equally spaced in the diagram

if the acceleration is different from zero in these cases the intervals are different in the same time intervals

Explanation:

In a drawing of displacement as a function of time, we can know if in motion it is steely or not, the relationship that describes the motion is

            x = v₀ t + ½ a t²

we see that we have two cases:

* if the acceleration is zero the displacements are equal in the same time interval, so we would see the points equally spaced in the diagram

* if the acceleration is different from zero in these cases the intervals are different in the same time intervals. In the case of positive acceleration the points are spaced and in the chaos negative acceleration the points are getting closer to each other

A paint brush is dropped from the top of a tall ladder and free falls to the ground. What changes, if any, would be observed of the velocity and the acceleration of the brush as it falls? Pick the two answers. The velocity increases. The velocity decreases. The velocity remains a constant value. The acceleration increases. The acceleration decreases. The acceleration remains a constant value.

Answers

Answer:

Explanation:

As the paint brush is dropped from the top of a tall ladder it started free falling

i.e. velocity of brush increases as it falls down due to the acceleration provided by gravity.

We know acceleration due to gravity is the attraction experienced by the object due to earth attraction

Value of acceleration due to gravity is constant i.e. [tex]9.8\ m/s^2[/tex]

Therefore the correct choice is

velocity is increasing and acceleration is constant

How does the current values in and out of the battery compare to the sum of currents going through the light bulbs?

Note: This is for Parallel circuits.

Answers

The current values in and out of the battery is going to be equal to the sum of the currents going through the light bulbs. In a parallel circuit, the current is divided as it enters different branches and light bulbs. However, the amount of current leaving the battery is always going to be the same as the amount of current entering the battery. Therefore, while current divides in a parallel circuit, the total amount of current always remains the same.

Corrected question;

Chef Andy tosses an orange in the air, then catches it again at the same height. The orange is in the air for 0.75 s. We can ignore air resistance. What was the orange's velocity at the moment it was tossed into the air?

Explanation:

Applying the equation of motion;

v = u + at. ....1

Where

u = initial speed

v = final speed

a = acceleration

t = time taken

Given;

Total time of flight t = 0.75s

Acceleration due to gravity g = 9.8 m/s^2

Considering the first phase of flight, during the upward motion to the maximum height. The final velocity at the maximum height is zero and the time of flight of the phase is equal to half of the total flight time.

v1 = 0

t1 = t/2 = 0.75/2 =0.375s

From equation 1;

v1 = u - gt1

Substituting the values;

0 = u - 9.8(0.375)

Solving for u;

u = 9.8(0.375)

u = 3.675

u = 3.68 m/s

Initial velocity = 3.68 m/s

In which sound wave application are sound waves absorbed?

Answers

Answer: ultrasonic cleaners

Explanation:

To solve this we must be knowing each and every concept related to  sound wave. Therefore, in ultrasonic cleaners, sound waves are absorbed.

What is sound wave?

A sound is a type of energy or a vibration that moves through a material such as air or water. Sound may pass through such a gaseous medium as well. It is anything that is audible. The velocity of sound varies depending on the medium.

A wave is a medium that transmits energy from one location to another. Waves are classified into three types: transverse waves, longitudinal waves, or surface waves.

Transverse waves transport the material back and forth in a right angle towards the energy movement. Longitudinal waves transmit energy through compressing then expanding the medium, allowing the energy to travel ahead. In ultrasonic cleaners, sound waves are absorbed.

Therefore, in ultrasonic cleaners, sound waves are absorbed.
