When a positively charged object moves in the same direction as the electric field, the electric potential energy of the object?

Biology
2 answers:
Papessa [141]3 years ago

Answer: option 2. increases

Explanation: The work done to move a charge in an electric field is given by:

U = F.d = F d cos θ

where F is the electric force between two charges and d is the distance between two charges and θ is the angle between the direction of force exerted and direction of displacement of charge.

F = q E

Where, q is the charge and E is the electric field.

⇒ U = q E d cos θ

When a positively charge object moves in an electric field in the same direction, θ = 0°, cos 0°= 1

⇒ U = q E d

As the charged object moves, d would increase. Electric field (E) and charge (q) are constant. Hence, the electric potential energy  would increase.

¿Como se sintetiza una proteína?
Arisa [49]
La síntesis de proteínas se realiza en los ribosomas situados en el citoplasma celular. En el proceso de síntesis, los aminoácidos son transportados por ARN de transferencia correspondiente para cada aminoácido hasta el ARN mensajero donde se unen en la posición adecuada para formar las nuevas proteínas.

In humans, the quadriceps muscle is a skeletal leg muscle under voluntary control. As such, it contracts in response to signals
Masja [62]

Answer:

The correct answer is - operation of reflex arc.

Explanation:

The reflex arc is a unique and special type of neural pathway that starts with a sensory neuron and ends with a motor neuron. In this operation sensory neuron acts as the receptor and motor neuron is effector. This type of neural circuit helps in faster response.

Voluntary muscles like quadriceps muscle are normally in control voluntarily however, such muscle may contract involuntary due to reflex arc. This type of contraction takes place before the signal has even reached the brain.

In this response the sensory neuron takes the signal to the spinal cord and then motor neuron to the effector muscle for faster response.

Thus, the correct answer is - operation of reflex arc.

¿para que sirven los plasmodesmos?
stiv31 [10]

Answer:

Los plasmodesmos forman una ruta importante para la comunicación entre las células vegetales. Regulan la comunicación de célula a célula, permitiendo así la diferenciación de órganos y tejidos vegetales.

Los plasmodesmos facilitan el movimiento de moléculas entre las células, desde pequeños productos fotosintéticos hasta grandes proteínas y ARNm. En el tejido vascular, los plasmodesmos son cruciales para el movimiento de nutrientes. También son cruciales durante el desarrollo porque, a diferencia de las células animales, las células vegetales no se mueven. Por tanto, la expresión correcta de genes tanto temporal como espacialmente es importante. Mientras que las células vegetales, como las células animales, son capaces de interactuar receptor-ligando para enviar señales a otras células, los plasmodesmos ofrecen contacto directo. Además, el tamaño de la manga difiere en diferentes tipos de células y tejidos vegetales. Por tanto, los plasmodesmos son un componente celular activo en el transporte intercelular, durante el desarrollo y en el tejido maduro.
