Answer:
Newton's first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.
Explanation:
A uniform electric field exists in a region between two oppositely charged plates. An electron is released from rest at the surface of the negatively charged plate and strikes the surface of the opposite plate, 2.0 cm away, in a time 1.5 x 10-8 s. The speed of the electron in millions m/sec as it strikes the second plate is: A. 13.3 B. 133 C. 2.67 D. 26.7 E. 534
Answers
Answer:
A. 13.3
Explanation:
First, we find the velocity of the electron in meters/sec, as follows:
[tex]v = \frac{d}{t}\\[/tex]
v = velocity of electron = ?
d = distance between plates = 2 cm = 0.02 m
t = time elapsed = 1.5 x 10⁻⁸ s
Therefore, using these values in the equation, we get:
[tex]v = \frac{0.02\ m}{1.5\ x\ 10^{-8}\ s}\\\\v = 1333333.33\ m/s[/tex]
Now, we convert this to million m/s:
[tex]v = (1333333.33\ m/s)\frac{1\ million\ m}{100000\ m}\\\\v =13.3\ million\ m/s[/tex]
Therefore, the correct answer is:
A. 13.3

The 500 series bullet train travels between Tokyo and Hakata, Japan. If it is heading north with a momentum of 13,194,098.64 kg • m/s and at a velocity of 261.8 km/h, what is its mass?
Answers
Answer:
The mass of the 500 series bullet train is 181.4 tonnes.
Explanation:
The momentum is given by:
[tex] p = mv [/tex]
Where:
m: is the mass =?
v: is the velocity = 261.8 km/h
p: is the momentum = 13194098.64 kg*m/s
By solving the above equation for "m" we have:
[tex]m = \frac{p}{v} = \frac{13,194,098.64 kg*m/s}{261.8 km/h*\frac{1000 m}{1 km}*\frac{1 h}{3600 s}} = 181.4 tonnes[/tex]
Therefore, the mass of the 500 series bullet train is 181.4 tonnes.

Answers
Answer:
Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.

Explanation:
compute the velocity of an object orbiting at height 2Re above the surface of earth
Answers
Answer:
The orbital speed can be found using v = SQRT(G*M/R). The R value (radius of orbit) is the earth's radius plus the height above the earth - in this case, 6.59 x 106 m.
The velocity of an object orbiting at height 2Re above the surface of earth be 14380 m/s.
What is velocity?The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.
The orbital velocity of an object orbiting around the Earth can be expressed as:
v = √(GM/R).
Where:
G = universal gravitational constant = 6.67408 × 10⁻¹¹N m² kg⁻².
M = mass of Earth = 5.97219 × 10²⁴ kilograms.
R = distance between the object and the center of Earth.
According to the question, the object orbiting at height 2[tex]R_e[/tex] above the surface of earth. So, distance between the object and the center of Earth is: R = radius of Earth + 2[tex]R_e[/tex]
= 3[tex]R_e[/tex]
= 3 × 6,371 km
= 1.9113 × 10⁶ m.
So, the velocity of the object : v = √(GM/R).
= √( 6.67408 × 10⁻¹¹× 5.97219 × 10²⁴/1.9113 × 10⁶ ) m/s
= 14380 m/s.
Hence, the velocity of the object be 14380 m/s.

the answers the correct one is A
F = 0
Explanation:
To find the net force we must apply Newton's second law
F -W = ma

Un tren emite un sonido a 480hz determina la frecuencia que percibe el observador cuando el observador se aleja a 12m/s del tren que ha quedado en reposo velocidad del sonido en el aire 340m/s
Answers
Answer:
La frecuencia que percibe el observador es 463 Hz.
Explanation:
El efecto Doppler se define como el cambio de frecuencia aparente de una onda producida por el movimiento relativo de la fuente respecto a su observador. En otras palabras, este efecto es el cambio en la frecuencia percibida de cualquier movimiento ondulatorio cuando el emisor y el receptor, u observador, se desplazan uno respecto a otro.
La siguiente expresión se considera el caso general del efecto Doppler:
[tex]f'=f*\frac{v+-vR}{v-+vE}[/tex]
Donde:
f’, f: Frecuencia percibida por el receptor y frecuencia emitida por el emisor respectivamente. Su unidad de medida en el Sistema Internacional (S.I.) es el Hertz (Hz), que es la unidad inversa del segundo (1 Hz = 1 s-1) v: Velocidad de propagación de la onda en el medio. Es constante y depende de las características del medio. En este caso se considera que la velocidad del sonido en el aire es de 340 m/s vR, vE: Velocidad del receptor y del emisor respectivamente. Su unidad de medida en el S.I. es el m/s ±, ∓:Utilizaremos el signo +:
En el numerador si el receptor se acerca al emisor
En el denominador si el emisor se aleja del receptor
Utilizaremos el signo -:
En el numerador si el receptor se aleja del emisor
En el denominador si el emisor se acerca al receptor
En este caso:
f= 480 Hzv= 340 m/svR= 12 m/s (el receptor es el observador)vE=0 (el emisor es el tren, que se encuentra en reposo)Y como el receptor se aleja del emisor, la expresión del efecto Doppler queda determinada como:
[tex]f'=480 Hz*\frac{340 m/s-12 m/s}{340 m/s-+0 m/s}[/tex]
Resolviendo se obtiene:
[tex]f'=480 Hz*\frac{340 m/s-12 m/s}{340 m/s}[/tex]
[tex]f'=480 Hz*\frac{328 m/s}{340 m/s}[/tex]
f'= 463 Hz
La frecuencia que percibe el observador es 463 Hz.

wave changes its path from its initial direction so this phenomenon is known as Refraction of wave
Explanation:
When wave travels from one medium to other medium the due to change in the speed of the wave propagation it deviates from its initial path.
The deviation of the wave from its initial path is known as refraction of wave
Here we can see that wave incident on medium 1 with some angle with the boundary
Then it enters into other medium and then travels in other direction
So here wave changes its path from its initial direction so this phenomenon is known as Refraction of wave
