Which direction do electrons travel
Sedaia [141]

Answer:

option a negative to positive

Explanation:

The flow of electrons is termed electron current. Electrons flow from the negative terminal to the positive. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative

Matter behaving like a wave rather than a particle is best illustrated by which phenomenon?
miss Akunina [59]
The phenomenon that best illustrates on matter behaving like a wave instead of being a particle is called the interference patterns of electrons. In addition, this phenomenon was described by experimenting that made use of an electron wherein the wave nature of electrons was observed.

A car is moving at 6 m/s and then accelerates at 1.7 m/s2 for 4.2 seconds. What is the final velocity of the car?
Bad White [126]

Explanation:

Hey there!!

Here,

Initial velocity (u) = 6m/s.

Acceleration (a) = 1.7m/s^2.

Time (t) = 4.2s.

final velocity (v) = ?

We have,

a =  \frac{v - u}{t}

Putting their values,

1.7 =  \frac{v - 6}{4.2}

7.14 = v - 6

v = 7.14 + 6

Therefore, the final velocity is 13.14 m/s.

According to Newtons third law of motion when one object exerts a force on a second object what is true about the forces?
fomenos

Answer:

D.They are equal in magnitude and opposite in direction

Explanation:

  • Newton's third law states that the action force is always associated with a reaction force.
  • When a body 'A' exerts a force on body 'B', it is called the force of action.
  • When the body 'B' in turn resist the force of 'A' is called the reaction force. It is the reactive force acted upon by the body 'B' on 'A'.
  • This reaction force is equal in magnitude of the action force.
  • If the two bodies remain in the same horizontal line, the 'A' exerts a force in the direction towards 'B' and the body 'B' exerts a reaction force in the direction towards 'A'.
  • Hence, the two forces that are exerted by the bodies are equal in magnitude and opposite in direction.
