<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
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.
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.
