Answer:
the radius of bigger loop = 6 cm
Explanation:
given,
two concentric current loops
smaller loop radius = 3.6 cm
]current in smaller loop = 12 A
current in the bigger loop = 20 A
magnetic field at the center of loop = 0
Radius of the bigger loop = ?
now, on solving
= 
= 6 cm
hence, the radius of bigger loop = 6 cm

Magnitude of the force = 50N
<u />
<u>Explanation:</u>
Let one force be X
And the second force be Y
Both the forces are perpendicular, so α = 90°
The resultant R of the two forces = 100N
Angle between resultant and 1 force, α = 60°
We know,
R² = X² + Y² + 2XYcos 90
100² = X² + Y²
If X makes an angle of Φ = 60°
Then, tan Ф = Y sin α / X + Y cos α
Putting the values we find,
tan 60 = Y/X
Y = √3X
Putting Y = √3X in equation 1 we get,
(X)² + (√3X)² = 100 X 100
4X² = 100 X 100
X² = 2500
X = 50N
Therefore, magnitude of the force = 50N
Heat flows naturally from a warmer object (higher energy) to a cooler one (lower energy).
Answer:
Question 1: the plates are moving toward one another.
Question 2: The Himalayan Mountains in India
Question 3: Because mountains are formed instead.
Explanation:
The paragraph explains that the plates continue to move closer to one another while forming multiple mountains.
The paragraph explains, " a well-known example of this is the formation of the Himalayan Mountains in India,"
The area of the Himalayan Mountains are better suited for the formation of mountains rather than volcanoes.
Have a nice day!! Good Luck!! Brainliest would be appreciated!!!
