Answer:

Pedro Infante Cruz was a Mexican actor and singer. Hailed as one of the greatest actors of the Golden Age of Mexican cinema, he is considered an idol in Mexico and other Latin American countries such as Venezuela, Guatemala and Peru. He along with Jorge Negrete and Javier Solís are considered the best ranchera singers. Infante was born in Mazatlán, Sinaloa, but raised in nearby Guamúchil. He died on 15 April 1957 in Mérida, Yucatán, in a plane crash during a flight en route to Mexico City, after an engine failed on takeoff. His remains were later identified by a bracelet found.

His film career began in 1939 with him appearing in more than 60 films - 30 of them with his brother Ángel Infante, and starting in 1943 he recorded about 350 songs. For his performance in the movie Tizoc, he was awarded the Silver Bear for Best Actor at the 7th Berlin International Film Festival.

The armature windings of a dc motor have a resistance of 3.0 Î©. The motor is connected to a 120V line, and when the motor reach

svlad2 [7]

Answer:

0.6 A

Explanation:

As the motor gears towards full speed, the voltage of the circuit tends to become the difference that exists between the line voltage and the that of the back emf. Remembering Ohm's law, we then apply it to get the final, lower current that is based on the reduced voltage Ef. We use the provided resistance in the question, that is 3 ohms.

Ef = (120 V) - (117 V) = 3 V

If = Ef/R = (3 V) / (5.0 Ω) = 0.6 A

Briefly discuss:

IrinaK [193]

Answer:

(i) Si device are coated with B or Li for neutron detection

(ii) Fast neutrons are normally first slowed down to thermal energies before measurement

(iii) The strip detectors consists of p⁺ and n implants in the region of a very thin (300 to 400 μm) depletion zone though which the neutrons traverse producing a readout based on the generated charges being directed to the cathode, p⁺, material which then transmits the charge to the device electronics

Explanation:

(i) Detection of neurons with only an Si device in not possible due to the large neutrons path in Si such that the silicon needs to be coated with B or Li which readily interact with neutrons. The neutron interaction with the reactive coating produces an alpha particle which can be detected by the semi conductor and a nucleus

(ii) Neutrons having a kinetic energy that is more than 1 MeV which as such has a velocity of more than 15,000 km/s is known as fast neutrons or fission neutrons. The fast neutrons are slowed in a nuclear reactor by neutron moderation to thermal energies

Due their high speed, fast neutrons are normally slowed down which however results in the loss of some vector properties of the neutron

Techniques for fast neutron detection includes,

1) Recoil detectors which are capable of fast neutron detection without moderation

2) Bonner spheres detector first converts the fast moving electron to slow down before detection

3) Scintillation counter are widely used but require the conversion of the neutron to a charged particles before detection

(iii) Strip detectors provide high precision measurement of a particle's crossing point which can be further improved by use of low noise electronics

Applications of silicon strip detectors include

1) Particle tracking in research in particle physics

2) Particle tracking in researches in x-spectroscopy nuclear research

3) Imaging in x-talography

4) Medical research imaging

5) Particle tracking and imaging in astrophysics.

What does the slope of a Position vs. Time graph represent?

attashe74 [19]

Your question asks what the slope of a Position vs. Time graph represents.

Your answer would be Velocity.

The slope of a Position vs. Time graph would represent the velocity of the object.

If the slope is positive, then the object has a positive velocity ,in which it is going forward.

If the slope is negative, then the object has a negative velocity, which means that it's going the opposite direction, or backwards.

If the slope is at a "horizontal" position, this means that the object is stopped or isn't moving at all.

A colorless liquid is located in a graduated cylinder that measures 35 mL. If the graduated cylinder has a mass o

Alchen [17]

Density of liquid is 1 g/mL.

<h3>What is density of a substance?</h3>

Density is the ratio of the mass and the volume of a substance

Mathematically density of a substance is given as follows:

Density = mass/volume

The density of the substance is:

mass of liquid = 172 - 137 = 35 g

volume of liquid = 35 mL

Density of liquid = 35 g/35 mL

Density of liquid = 1 g/mL

In conclusion, density is obtained as a ratio of mass and volume.

13. Calculate the total heat energy in Joules needed to convert 20 g of substance X from -10°C to 70°C?

sergeinik [125]

The heat required to convert the unknown substance X from one phase to another is 1600 J times the specific heat of that substance.

Explanation:

The heat energy required to convert a substance or to heat up or increase the temperature of a substance can be obtained from the specific heat formula.

As per this formula, the heat energy applied should be equal to the product of mass of the substance with temperature gradient and also with specific heat of the substance. Basically, the heat provided to increase or convert a substance should be more than the specific heat of the substance.

$Q = mc del T$

Since, here the mass of the substance X is given as m = 20g and the temperature change is given from -10°C to 70°C.

Then ΔT = (70-(-10))=70+10=80°C.

As the substance is unknown, the specific heat of that substance can also not be determined. Hence keep it as C.

$Q = 20*C*80$

Q = 1600C J

Thus, the heat required to convert the unknown substance X from one phase to another is 1600 J times the specific heat of that substance.
