0.125 C of charge flow out of a
5.00 V battery in 6.30 s. How
much resistance is attached to the
battery?
(Hint: What is the definition of current?)
(Unit = Ohm)

Answers

Answer:

Resistance = 252.53 Ohms

Explanation:

Given the following data;

Charge = 0.125 C

Voltage = 5 V

Time = 6.3 seconds

To find the resistance;

First of all, we would determine the current flowing through the battery;

Quantity of charge, Q = current * time

0.125 = current * 6.3

Current = 0.125/6.3

Current = 0.0198 A

Next, we find the resistance;

Resistance = voltage/current

Resistance = 5/0.0198

Resistance = 252.53 Ohms

You have a 100 ohm resistor. How
much resistance must you add in
parallel to the 100 ohm resistor to
create an equivalent resistance of
75.0 ohms?

Answers

Answer:

R2 = 300 Ohms

Explanation:

Let the two resistors be R1 and R2 respectively.

RT is the total equivalent resistance.

Given the following data;

R1 = 100 Ohms

RT = 75 Ohms

To find R2;

Mathematically, the total equivalent resistance of resistors connected in parallel is given by the formula;

[tex] RT = \frac {R1*R2}{R1 + R2} [/tex]

Substituting into the formula, we have;

[tex] 75 = \frac {100*R2}{100 + R2} [/tex]

Cross-multiplying, we have;

75 * (100 + R2) = 100R2

7500 + 75R2 = 100R2

7500 = 100R2 - 75R2

7500 = 25R2

R2 = 7500/25

R2 = 300 Ohms

All students except one are cheating on a test. The one student who is not cheating on the test is exhibiting abnormal behavior. Based on the information provided in the article, explain the conclusion of this scenario. Which definition for abnormal behavior would apply to this scenario? (Site 1)

Answers

Answer: See explanation

Explanation:

According to clinical psychology, an abnormal behavior is when an act results in a significant distress and is deviant from the normal practice.

In this case, while the whole class is cheating, one student isn't. This shows that the student is deviating from what every other person is doing. Since the student deviates from the norm, it's an abnormal behavior.

Answer:

The reason he might be exhibiting abnormal behavior is the fact that everyone except him is cheating on a test. He is the odd one out and due to this he might be anxious/nervous. Perhaps he thinks that since he is the only one not cheating that he might get a bad grade cause the teacher will assume he is cheating aswell. Another might be that he does not like being singled out. It's out of the norm and he does not particularly like it.

When a traffic light turns from red to green, it takes much more force and time for a large truck to get going than it does a small, compact car. This is an example of which law of motion?

Answers

Answer:

First Law of Motion.

Explanation:

Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.

In physics, Sir Isaac Newton's First Law of Motion is known as Law of Inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.

The inertia of a physical object such as a truck is greatly dependent or influenced by its mass; the higher the quantity of matter in a truck, the greater will be its tendency to continuously remain at rest.

Hence, it would take much more force and time for a large truck to get going when the traffic light turns green than it does for a small, compact car. This is an example of the first law of motion.

(PLEASE HELP !! )Does the chemical equation follow the Law of Conservation Of Matter?

The Law of Conservation infers that the matter within a system will perserve its quantity (less there's an outside factor which disrupts the system). There should be more Cl within the products side of the equation, and more Br within the reactants side (there should be general adjustment to make this problem balanced), so that the matter is equal in quantity within both sides of the equation.

diferencias que existen entre la marcha cuando caminamos, corremos sin balón y corremos con balón

Answers

Answer:

La principal diferencia que existe entre la marcha cuando caminamos y cuando corremos, sea con o sin el balón, es la velocidad: al caminar, la velocidad es mucho menor que al correr, y a su vez, correr sin el balón da la posibilidad de correr mucho más rápidamente, debido a que no se requiere una coordinación entre los pasos y el control del balón.

Por otra parte, además de la velocidad, el ritmo cardiaco que se adquiere al caminar es mucho mas bajo que al correr, donde por causa del esfuerzo se aceleran las pulsaciones, aumentando la frecuencia cardiaca y, por lo tanto, la exigencia cardiovascular.

Highway safety engineers want to design roadside barriers that will crumple
in the event that a car drives off the road and collides with them, slowing
down the car more gradually. The average person has a mass of 68 kg and
travels on a highway at a velocity of 27 m/s. If the engineers know that the
maximum force that a person can safely withstand is 2180 N, approximately
how much time is required to crumple the barrier to safely slow the person
with this force?

Answers

Answer:

[tex]0.84\:\text{s}[/tex]

Explanation:

The impulse-momentum theorem states that the impulse on an object ([tex]F\Delta t[/tex]) is equal to the change in momentum of that object ([tex]\Delta p[/tex]).

Set up the following equation:

[tex]F\Delta t=\Delta p[/tex]

Solving for change in momentum:

The momentum of an object is equal to [tex]p=mv[/tex], where [tex]m[/tex] is the mass of the object and [tex]v[/tex] is the velocity of the object. Since the person's final velocity will be zero, their final momentum will also be zero. Therefore, the person's change in momentum is [tex]68\cdot 27-0=1836\:\text{kgm/s}[/tex].

Solving for time:

[tex]2180\cdot\Delta t = 1836,\\\Delta t =\frac{1836}{2180},\\\Delta t =\boxed{0.84\:\text{s}}[/tex]

the diagram below represents the orbits of earth, comet temple-tuttle, and planet x, another planet in out solar system. arrows on each orbit represent the direction of movement. which objects orbit would have and eccentricity close to 1?


Answers

Answer:

the most elliptical orbit is that of COMETA

Explanation:

The eccentricity of a curve in defined as the ratio between lacia to the focus, called c and the value of the axis greater than

         ε = c / a

if we use Pythagoras' theorem

         c = [tex]\sqrt{a^2 - b^2}[/tex]

   substituting

           ε = [tex]\sqrt{1 - (b/a)^2 }[/tex]

if   ε = 0 we have a circumference

In the diagram presented the orbit of the comet is an ellipse a> b

          ε=[tex]\sqrt{1- x} \\ x = (\frac{b}{a} )^2[/tex]

if we expand in series

             ε = 1 - x/2  

             ε=  [tex]1 - \frac{1}{2} \ (\frac{ b}{a} )^2[/tex]

if we neglect the non-linear terms

            ε = 1

Earth's orbit is a small ellipse

             b / a = 149 10⁶ / 151 10⁶

             b / a = 0.98675

             ε = [tex]\sqrt{1- 0.98675^2}[/tex]

               ε = 0.16

a very small ellipse

Planet X, despite not having data, it seems that the sun is in the scepter of the orbit, so b = a

therefore  both the semi-axes of the curve

        e = a / b

Consequently, the most elliptical orbit is that of COMETA.

A un cuerpo de 4kg que está en reposo sobre la superficie de la tierra, se aplica durante 8seg una fuerza de 60N dirigida verticalmente hacia arriba. Calcule la altura máxima que alcanza el cuerpo.

Answers

Answer:

[tex] y_{t} = 253.94 m [/tex]

Explanation:

Para resolver este problema debemos contemplar dos tramos.

En el primer tramo, la fuerza aplicada impulsa al cuerpo a subir una altura dada debido a la aceleración que genera esa fuerza.

[tex] \Sigma F = ma [/tex]

[tex] F - P = ma [/tex]

[tex] F - mg = ma [/tex]

En donde:

F: es la fuerza aplicada = 60 N

P: es el peso del cuerpo = mg

m: es la masa del cuerpo = 4 kg

g: es la aceleración debido a la gravedad = 9.81 m/s²

a: es la aceleración

Entonces, la aceleración generada por la fuerza aplicada es:

[tex] a = \frac{F - mg}{m} = \frac{60 N - 4kg*9.81 m/s^{2}}{4 kg} = 5.19 m/s^{2} [/tex]

Ahora, debemos calcular la altura recorrida mientras el cuerpo está acelerado hacia arriba:

[tex] y_{{1}} = y_{0} + v_{0}t + \frac{1}{2}at^{2} [/tex]  

En donde:

[tex] y_{1}[/tex]: es la altura final del tramo 1 =?                                                                          [tex] y_{0}[/tex]: es la altura inicial = 0  

[tex] v_{0}[/tex]: es la velocidad inicial = 0 (parte del reposo)  

t: es el tiempo = 8 s

[tex] y_{1} = 0 + 0 + \frac{1}{2}5.19 m/s^{2}*(8 s)^{2} = 166.08 m [/tex]  

Por lo tanto, mientras el cuerpo está acelerado (durante los 8 s) recorre 166.08 metros.  

Ahora, en el segundo tramo el cuerpo sigue subiendo hasta alcanzar una altura máxima para luego comenzar a descender. Podemos usar la siguiente ecuación para calcular la altura recorrida.  

[tex] v_{f}^{2} = v_{0}^{2} - 2gy_{2} [/tex]  

En donde:    

[tex] v_{f}[/tex]: es la velocidad final = 0 (en la altura máxima)

[tex] v_{0}[/tex]: es la velocidad inicial

Primero debemos encontrar la velocidad inicial en el segundo tramo, que es igual a la velocidad final del primer tramo:

[tex] v_{f} = \sqrt{v_{0} + 2ay_{1}} = \sqrt{0 + 2*5.19 m/s^{2}*166.08 m} = 41.52 m/s [/tex]    

Entonces, la altura recorrida en el segundo tramo es:

[tex] y_{2} = \frac{v_{0}^{2} - v_{f}^{2}}{2g} = \frac{(41.52 m/s)^{2} - 0}{2*9.81 m/s^{2}} = 87.86 m [/tex]

Finalmente, la altura máxima es:

[tex]y_{t} = y_{1} + y_{2} = 166.08 m + 87.86 m = 253.94 m[/tex]
