A proton with an initial speed of 400,000 m/s is brought to rest by an electric field. Did the proton move into a region of high
Anton [14]

A proton is initially moving at high speed

v = 400000 m/s

so here initially proton is having high speed and high kinetic energy

now this proton comes to rest by external electric field

so the potential energy of proton will increase or we can say that kinetic energy will convert into electrostatic potential energy

so here the proton must have to move at higher potential region

so here correct answer must be

b. Because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.

Explain why chlorine forms a -1 ion, but sulfur forms a -2 ion.
alukav5142 [94]

For a chlorine atom to become a chloride ion, it must gain an electron.The chloride ion has a negative charge and is written as Cl-. Chlorine gains an electron because it has seven valence electrons, and to be a full octet, it gains an electron.

Calcular la aceleracion resultante de una particula que gira a 5Hz y su radio de giro es de 50 cm
DiKsa [7]

Answer:

a_C=12.5\frac{m}{s^2}

Explanation:

Hola.

En este caso, dado que conocemos la frecuencia con la que la particula gira (ω), 5 Hz o 5 giros de radio de 50 cm (0.5 m) cada uno en 1 segundo, podemos calcular la aceleración centrípeta con:

a_C=\omega^2 r

a_C=(\frac{5}{s})^2*0.5m\\ \\a_C=\frac{25}{s^2} *0.5m\\\\a_C=12.5\frac{m}{s^2}

¡Saludos!
