Question : How does the direction and magnitude of Fe compare to Fg

answer : Not enough information is given

Explanation:

From the above information given in the question the direction and magnitude of FE cannot be compared to Fg and this is simply because the mass of the particle that  force is been exerted on is not given therefore we cannot ascertain the magnitude of the gravitational force. Therefore we can conclude that not enough information is given

Answer:

A) As the ambulance's siren moves toward a stationary hearer, the quality of sound will have a higher pitch

B) As the ambulance's siren moves away from a stationary hearer, the quality of sound will have a lower pitch.

Explanation:

From Doppler effect, the closer the source of sound gets to the observer, the higher the frequency and in turn the higher the pitch.

Meanwhile, the farther a source goes from an observer, the lower the frequency of the sound and also the lower the pitch.

Thus, as the ambulance's siren moves toward a stationary hearer, the quality of sound will have a higher pitch.

As the ambulance's siren moves away from a stationary hearer, the quality of sound will have a lower pitch.

Answer:

a. The quality of the sound would have a high pitch and thus be loud.

b. The quality of the sound would have a low pitch and thus would have a lower volume than the sound from the source.

Explanation:

Using the formula for Doppler shift f' = (v ± v')f/(v ± v") where v = speed of sound in air, v'= speed of hearer = 0 m/s (since he is stationary), v" = speed of ambulance and f = frequency of sound from ambulance

So, f' = (v ± v')f/(v ± v")

f' = (v ± 0)f/(v ± v")

f' = vf/(v ± v")

a. What is the quality of the sound of an ambulance's siren when it moves toward a stationary hearer?

Since the source (ambulance) moves towards the detector, (hearer), we would get an upwards shift in frequency. (Since our denominator has to be a minimum, so we use the minus sign for v"). So, the quality of the sound would have a high pitch and thus be loud.

b. What is the quality of the sound of an ambulance's siren when it moves away from a stationary hearer?

Since the source (ambulance) moves away the detector, (hearer), we would get a downward shift in frequency. (Since our denominator has to be a maximum, so we use the plus sign for v"). So, the quality of the sound would have a low pitch and thus would have a lower volume than the sound from the source.

Answer:

Lo primero que hay que recordar es la relación:

Velocidad = Distancia/tiempo.

Para el caso de Pedro, el vive a 5km de la escuela (es decir, para llegar a la escuela, el debe recorrer -5km, entonces la distancia es -5km), y recorre esa distancia en 0.25 horas, entonces su velocidad es:

Velocidad = -5km/0.25hr = -20km/h

Esto significa que Pedro se mueve con una velocidad de -20km/h, lo que significa que se mueve hacia el oeste con un módulo de 20km/h

Para el caso de Juan, el vive a -4km de la escuela, entonces el tendrá que recorrer 4km para llegar a la escuela, y los recorre en 0.25 horas, entonces su velocidad sera:

Velocidad = 4km/0.25h = 16 km/h

Lo que significa que Juan tiene una velocidad de 16km/h hacia el este.

Answer:

La velocidad del sistema bala-bloque es 5 metros por segundo.

Explanation:

El enunciado tiene una omisión gramatical. La forma correcta es la siguiente:

Una bala de 0.8 kilogramos de masa se mueve horizontalmente con una velocidad de 30 metros por segundo y se introduce en un bloque de 4 kilogramos, inicialmente en reposo. ¿Cuál es la velocidad de la bala y el bloque después del impacto?

Esta situación es un caso clásico de colisión enteramente inelástica, en donde el sistema bala-bloque no tiene influencia de fuerzas externas, entonces la situación queda descrita por la siguiente ecuación:

[tex]m_{b}\cdot v_{b,o} = (m_{b}+m_{B})\cdot v[/tex] (1)

Donde:

[tex]m_{b}[/tex] - Masa de la bala, en kilogramos.

[tex]v_{b,o}[/tex] - Velocidad inicial de la bala, en metros por segundo.

[tex]m_{B}[/tex] - Masa del bloque, en kilogramos.

[tex]v[/tex] - Velocidad del sistema bala-bloque, en metros por segundo.

Si sabemos que [tex]v_{b,o} = 30\,\frac{m}{s}[/tex], [tex]m_{b} = 0.8\,kg[/tex] y [tex]m_{B} = 4\,kg[/tex], entonces la velocidad del sistema masa-bloque es:

[tex]v = \frac{m_{b}}{m_{b}+m_{B}}\cdot v_{b,o}[/tex]

[tex]v = 5\,\frac{m}{s}[/tex]

La velocidad del sistema bala-bloque es 5 metros por segundo.

Answer:

F = 4117.64

Explanation:

First, we will calculate the acceleration of the hand, by using the third equation of motion:

[tex]2as = v_f^2 - v_i^2\\[/tex]

where,

a = acceleration = ?

s = distance covered = compression = 8.5 cm = 0.085 m

vf = final speed = 0 m/s

vi = iniial speed = 10 m/s

Therefore,

[tex]2a(0.085\ m) = (0\ m/s)^2-(10\ m/s)^2\\a = - 588.23\ m/s^2[/tex]

negative sign hows deceleration.

Now, we will calculate the force exerted by the hand:

[tex]F = ma = (7\ kg)(588.23\ m/s^2)\\[/tex]

F = 4117.64 N

Answer:

The correct answer is NONE the two forces must be equal and of opposite direction, the closest answer is D

Explanation:

In this exercise it is indicated that Jack pushes a car, it is desired that Jill pushes the car so that the speed is constant

take as positive the direction of Jack's thrust

             F_jack - F_jill = 0

              F_jill = F_jack

therefore the push of the two must be equal and Jill's push must have the opposite direction to Jack's push.

The correct answer is NONE the two forces must be equal and of opposite direction, the closest answer is D

Answer:

A. respiration.

Explanation:

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.

Hence, the conversion of sugar to energy in the presence of oxygen is respiration.

Explanation:

Given that,

Masses, [tex]m_1=m_2=6500\ kg[/tex]

The distance between masses, d = 0.5 m

We need to find the gravitational force between two large trucks. The formula for the gravitational forces is given by :

[tex]F=G\dfrac{m^2}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{6500^2}{(0.5)^2}\\\\F=0.0112\ N[/tex]

So, the required force between masses is equal to 0.0112 N.

The main reason for this is the engineering and technology driven building construction in Chile than in Haiti

Explanation:

The main reason for this is the engineering and technology driven building construction in Chile than in Haiti. Most of the buildings in Haiti do not fit in the building byelaws norms as most of them were constructed in a short period of time with less engineering and at cheaper rate. While building in Chile were built adhering to the building codes and byelaws.

The base of the building is Chile were separated from each other using the “base isolation” technology and the were also more flexible as compared to the buildings in Haiti.  

The skyscrapers in Chile were constructed in a way that they can float on the arrangements of ball bearings and padded cylinders

Answer:

1 ohm

Explanation:

since there are two identical resistors, one resistor will be

R = [tex]\frac{4}{2}[/tex] =2ohm [ proven as in series [tex]R_{e} = 2 + 2 = 4ohm[/tex] ]

to calculate the equivalent resistance when in parallel:

[tex]\frac{1}{R_{e} } = \frac{1}{R_{1} } + \frac{1}{R_{2}}[/tex]

so,

[tex]\frac{1}{R_{e} } = \frac{1}{2} + \frac{1}{2}[/tex]

[tex]R_{e} = 1ohm[/tex]

Two identical resistors connected in series have an equivalent resistance of 4 ohms. The same two resistors, when connected in parallel, have an equivalent resistance of 1 ohm.

In a parallel circuit, voltage is thee same across each component in the circuit. The sum of the currents through each path is equal to the current from the source. However, the resistance cannot be added directly. It is calculated as:

1/Rt = 1/R1 + 1/R2 + 1/R3 1/Rt = 1/6.8 + 1/9.0 + 1/15

Rt = 3.08 ohms.

When resistors are connected in parallel, the equivalent resistance R will be less than the least resistance.

1/R = 1/R1 + 1/R2 + 1/R3 + 1/R4 + 1/R5

Since the 5 resistors are 10 ohms each, substitute them in to the formula

1/R = 1/10 + 1/10 +1/10 + 1/10 + 1/10

The LCM = 10

1/R = 5/10

Reciprocate both sides

R = 10/5 = 2 ohms

Therefore, Two identical resistors connected in series have an equivalent resistance of 4 ohms. The same two resistors, when connected in parallel, have an equivalent resistance of 1 ohm.

The smaller the mass of an object, the smaller its inertia, because the inertia of any object is directly proportional to the mass of the object

The ability of an object to resist changes in motion is known as inertia. The amount of inertia is directly related to an object's mass; in fact, as we frequently observe, the heavier an object is, the harder it is to change its direction of motion.

A straightforward illustration: While it is relatively simple to stop a tennis ball that has been thrown in our direction, we are aware that it is more difficult to stop a large truck that is moving in the same direction at the same speed. This is because the truck has a much higher mass than the tennis ball and a higher moment of inertia. As a result, inertia rises as mass does.

Since the inertia of any object is directly proportional to its mass, the smaller its mass, the less inertia it will have.
