Answer:
A. Gravitational force
C. Their charges
Explanation:
As we'll discuss in this lesson, he found that the force between charged particles was dependent on only two factors: the distance between the particles and the amount of electric charge that they carried.
Hope it help you
have a good day :)
Answer:
the direction of acceleration of the vehicle is the same direction of its velocity of car
s acceleration has the opposite direction to the car speed.
Explanation:
The initial acceleration of the car can be calculated with
v = v₀ + a t
a = (v-v₀) t
indicate that the initial velocity is zero (v₀ = 0 m / s)
a = v / t
a = 300 / t
the direction of acceleration of the vehicle is the same direction of its acceleration movement.
When the car collides with the wall, it exerts a force in the opposite direction that stops the vehicle, therefore this acceleration has the opposite direction to the car speed. But your module must be much larger since the distance traveled to stop is small
Answer:
- z axis
Explanation:
The magnetic force is perpendicular to its speed and the direction of the magnetic field, its equation being
F = q v x B
Where the bold indicates vectors, q is a positive charge,
The way to use this equation is with the rule of the right hand, the thumb points in the direction of the velocity, the other fingers extended in the direction of the magnetic field and the palm is the direction of the force for a positive charge.
Let's apply this to our case the speed is on the x axis and the force in ex. negative Y axis, the other fingers point perpendicular to the sheet, but since the charge is negative the magnetic field enters the sheet, this would be the negative z axis
Answer:
The human body can be a source of magnetic fields. Charged particles when moving through a magnetic field experiences a force. This magnetic force on a moving charge is at right angles to the velocity which makes it possible to use the knowledge of the magnetic field on charged particles to shield yourself from radiation exposure by staying at a right angle to the velocity of the field since magnetic fields tend to shield moving charged particles that is at a right angle to the field. Though the charged particle’s kinetic energy and speed will remain constant.
Explanation:
A magnetic field is a vector field that is generated whenever an electrical charge is moving,
