Answer:

C- Interact with charged particles.

Explanation:

When a charged particle is placed in the field of the other charged particle then it will experience electromagnetic force on it.

Answer: C; interact with charged particles.

Explanation: The elctromagnetic force is defined as:

F = q*E

Where q is the charge of a particle or charged object, and E is the electrical field, where the direction of the electric field defines the direction of the force.

Then, we need to have a charged particle in a outer eletrical field to have a electromagnetic force, which means that the correct answer is the option C; interact with charged particles.

For elliptical obits: the direction of the velocity of the satellite is _______________________ (always, seldom, never) perpendi
alexandr1967 [171]

Answer:

For elliptical orbits: seldom

For circular orbits: always

Explanation:

We start by analzying a circular orbit.

For an object moving in circular orbit, the direction of the acceleration (centripetal acceleration) is always perpendicular to the direction of motion of the object.

Since acceleration has the same direction of the force (according to Newton's second law of motion), this means that the direction of the force (the centripetal force) is always perpendicular to the velocity of the object.

So for a circular orbit,

the direction of the velocity of the satellite is always perpendicular to the net force acting upon the satellite.

Now we analyze an elliptical orbit.

An elliptical orbit correponds to a circular orbit "stretched". This means that there are only 4 points along the orbit in which the acceleration (and therefore, the net force) is perpendicular to the direction of motion (and so, to the velocity) of the satellite. These points are the 4 points corresponding to the intersections between the axes of the ellipse and the orbit itself.

Therefore, for an elliptical orbit,

the direction of the velocity of the satellite is seldom perpendicular to the net force acting upon the satellite.

State one advantage and one disadvantage of using a plane mirrior as a driving mirrior​
____ [38]

1). one disadvantage as using it is because it covers far less space. this would make much more blind spots. 2. the advantage of them is that they don't lie about the distances. the current convex mirrors we have in out cars right now, is that the imagine might look father or closer than they appear, which can be troubling at times.

plan mirrors are flat, car mirrors are convex.

How does the surface tension of water compared with the surface tension of most other liquids?
Anuta_ua [19.1K]
Surface tension is the direct measure of the cohesive forces between liquid molecules that allows them to form "film", making it more difficult to move an object through the liquid surface. Compared to other known liqiuds, the surface tension of water is much greater.
