Answer:

True

Explanation:

because their is friction(e.g take a ruler rub it in your hair then put it on top of a piece of paper on the table then u will see the process)among the two objects.

Calculate the average speed of the moon around the earth. The moon has a period of revolution of 27.3 days and an average distan
klio [65]
<h2>The average speed of the moon around the earth is 1021.74 m/s</h2>

Explanation:

Radius of moon around earth, r = 3.84 × 10⁸ m

Circumference of orbit = 2πr = 2 x 3.14 x 3.84 × 10⁸

Circumference of orbit = 2.41 x 10⁹ m

Time taken, t = 27.3 days = 27.3 x 24 x 60 x 60 = 2358720 seconds

We have

       Circumference of orbit = Speed of moon x Time taken

        2.41 x 10⁹ = Speed of moon x 2358720

       Speed of moon = 1021.74 m/s

The average speed of the moon around the earth is 1021.74 m/s

11111nata11111 [884]

Answer:

M_c = 100.8 Nm

Explanation:

Given:

F_a = 2.5 KN

Find:

Determine the moment of this force about C for the two cases shown.

Solution:

- Draw horizontal and vertical vectors at point A.

- Take moments about point C as follows:

                        M_c = F_a*( 42 / 150 ) *144

                        M_c = 2.5*( 42 / 150 ) *144

                        M_c = 100.8 Nm

- We see that the vertical component of force at point A passes through C.

Hence, its moment about C is zero.

Two parallel wires carry currents in the opposite direction. If wire 1 has a current of i, while wire 2 has a current of 2 i, wh
deff fn [24]

If two parallel wires carry current in opposite directions, they repel each other whereas if two parallel wires carry current in same direction, they attract each other.

force of the wire2 will be more compared to that of wire1.

According to force formula, wire2 will generate more force compared to wire1

force=magnetic flux density × current × length

here,

current is directly proportional to the force, so with increase in current the force will also increase.

force depends on the length and current of the wire.

So, from this we can conclude that wire 2 will produce more force compared to wire 1.
