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
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

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

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

Question 19 options:
Product
Reactant
Limiting reactant
Spontaneous reactant
Answer: Limiting reactant
Explanation:
The limiting reactant is a reactant will get completely consumed up in the reaction. This reactant being in low concentration will lead to the formation of limited amount of product.
In the given situation, since the butter cakes are required to be 3 sticks for making 3 cakes but only 2 cakes are available thus the butter stick is the limiting reactant.
How does the temperature of water affect the speed of the sound waves?
Answer:
Temperature is also a condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly.
Um joalheiro recebe uma encomenda onde ele deve fazer alguns anéis de prata. Ele dispõe de um pedaço de 100 g de prata mas precisa derrete-lo para colocar a prata em moldes específicos e construir esses anéis. O principal problema desse procedimento é que a temperatura de fusão da prata é muito alta e requer condições especiais. A prata possui temperatura de fusão de 961 ºC, calor latente de fusão de 21 cal/g e calor específico no estado sólido igual a 0,056 cal/gºC. Determine a quantidade de calor aproximada para fundir as 100 g de prata sabendo que sua temperatura inicial é de 20°C. A 2,1 kcal B 0,5 kcal C 7,4 kcal D 5,3 kcal E 6,3 kcal
Answer:
Correct option: C -> 7.4 kcal
Explanation:
First we need to find the energy necessary to heat the silver from 20°C to 961°. The change in temperature is 961 - 20 = 941, so the energy necessary is:
941 * 0.056 * 100 = 5269.6 cal
Then, for the melting process, we will need:
21 * 100 = 2100 cal
So the total energy needed is:
5269.6 + 2100 = 7369.6 cal = 7.4 kcal
Correct option: C

A car is going 60.0 mi/h and has to stop in 6.0 seconds. What is the car’s acceleration?
Explanation:
Convert mi/h to ft/s.
60.0 mi/h × (5280 ft/mi) × (1 h / 3600 s) = 88.0 ft/s
Find the acceleration.
a = Δv / Δt
a = (0 ft/s − 88.0 ft/s) / 6.0 s
a = -14.7 ft/s²
The driver must accelerate the car at the average rate of
- 10 mile / hour-second
for 6 seconds .
In which sound wave application are sound waves absorbed?
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.

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.
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

Calculate the energy that 1.5 kg of mass contains
Answer:
[tex]4.5(10)^8[/tex] joules
Explanation:
Mass–energy equivalence is the principle that says that anything that has mass has an equivalent amount of energy. Converse is also true.
The relation between energy and mass is given by [tex]E=mc^2[/tex]
Here, E denotes energy, m denotes mass and c denotes speed of light
Mass [tex](m)=1.5\,\,kg[/tex]
Speed of light (c) = 3 × [tex]10^8[/tex] m/s
Therefore,
[tex]E=1.5(3)(10)^8=4.5(10)^8[/tex] joules.
The S.I. unit of energy is joules which is equal to [tex]1\,\,kg\,\,m^2/s^2[/tex]
