A) The acceleration of this car is zero

Because, the question states that it is traveling at a constant velocity, meaning that it has no acceleration at all.

B the desert was once covered in water

**Answer:**

**Net charge inside the cube is 321.6 C**

**Explanation:**

Given charge density function is ρ =

side of cube is 2m

According to the definition of volume charge density total charge is given by

q = total charge = where dv = dxdydz is the volume element

on substututing the respected values we get

q =

on solving the above integration we get

q = x x

⇒ q = 321.6 C

**Therefore net charge inside the cube is 321.6 C**

Answer:

Impulse = 4Ns

Explanation:

Given the following data;

Force = 2N

Time = 2 seconds

To find the impulse experienced by the object;

Impulse = force * time

Impulse = 2*2

Impulse = 4Ns

Therefore, the impulse experienced by the object is 4 Newton-seconds.

A **current carrying wire** is placed vertically. The magnetic field around the wire is rotating clockwise around the **wire**. The current is moving from **top to bottom**

Holding a **current carrying wire **in your right hand with the thumb pointing in the direction of current flow, the fingers wrapping the wire will portray the magnetic lines of force direction, following the right-hand thumb rule.

As a result, a **current carrying conductor** is vertically held. If you follow the rule, the current should be passed through it to generate a clockwise magnetic field around the conductor from top to bottom.
