Answer:

Explanation:
Given:
- mass of the gadget,

- mass of fragment 1,

- mass of fragment 2,

- velocity of fragment 1,

- velocity of fragment 2,

- angle between the velocity 1 & 2,

<u>Now the mass of the third part:</u>



<u>The momentum of the gadget before and after collision is equal:</u>

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
C.
Thanks me later, that's my answer.
The slope of an object is given relative to an origin.
