If you are in motion can you have the same speed as someone else in motion but different velocities? Give an example

Answer:

Yes

Explanation:

Velocity is a vector quantity, meaning it has size and direction, as opposed to speed, a scalar quantity which only has size.

An example is speed may be 30km/h, and an example of velocity is 30km/h East.

Therefore two people can have the same speed and different velocities because they can be traveling in different directions.

For example, you and your friend could be doing shuttles together but you started at one wall and they started at the other, so even though you are running at the same speed, you always have different velocities because they are running in the opposite direction as you.

Hope this helped!

The correct equation for the x component of a vector named A with an angle measured from the x axis would be which of the follow

Lady_Fox [76]

Answer:

Acosθ

Explanation:

The x-component of a vector is defined as :

Magnitude * cosine of the angle

Maginitude * cosθ

The magnitude is represented as A

Hence, horizontal, x - component of the vector is :

Acosθ

Furthermore,

The y-component is taken as the sin of the of the angle multiplied by the magnitude

Vertical, y component : Asinθ

Charge is distributed uniformly along a long straight wire. the electric field 2 cm from the wire is 20 n/c. the electric field

Serjik [45]

The electric field 4cm from the wire is

$É = 10nc { }^{ - 1}$

Given:

charge is distributed uniformly along a long straight wire.

electric field 2cm from the wire is 20n/c

To find:

electric field 4cm from the wire

what is electric field?

Electric field is the region around charge particle or charged body in which if another charge is placed it experiences electrostatic force.An electric field is the physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them.

$E ∝ \frac{1}{r}$
