Explanation: Velocity is the displacement of an object during a specific unit of time. Two measurements are needed to determine velocity. Displacement and time. Displacement includes a direction, so velocity also includes a direction. Speed with direction. Velocity can be an average velocity or an instantaneous velocity. Units for velocity are the same as for speed: m/s, km/h, and mph. Delta x(Δx) is the symbol used for displacement. Delta (Δ) means to "change in." Δx means to "change in position." Δx is calculated by final position minus initial position. Velocity formula: → v=Δx/t as a fraction.
v=Δx/t

Answer:
<em>F=8.87 N</em>
Explanation:
<u>Coulomb's Law
</u>
The electrostatic force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.
Written as a formula:

Where:

q1, q2 = the objects' charge in coulomb
d= The distance between the objects in meters
Object 1 has a charge of

Object 2 has a charge of

They are separated by a distance of
d = 0.099 m
Calculate the force:

F=8.87 N
Answer:

Explanation:
As we know that the force per unit length of two parallel current carrying wires is given as

here we know that


d = 2.2 cm
now from above equation we have



Answer:
buildings are made of stone,bricks or embedded into the ground can feel cooler thanks to the high "thermal mass"of this materials.
