A. Physics
The study of how objects interact with each other
Answer:
Explanation:
Mass: M, Length: L.
The formula that gives center of mass is
In the case of a non-uniform mass density, this formula converts to
where the denominator is the total mass and the nominator is the mass times position of each point on the rod.
We have to integrate the mass density over the total rod in order to find the total mass. Likewise, we have to integrate the center of mass of each point (xσ(x)) over the total rod. And if we divide the integrated center of mass to the total mass, we find the center of mass of the rod:
Here x's are cancelled. Otherwise, the denominator would be zero.
Answer:
Explanation:
Magnitude of magnetic field due to a current carrying conductor
= ( μ₀ / 4π ) x 2I / d , I is current , d is distance from wire . This formula has been derived from Ampere's Law.
= 10⁻⁷ x 2 x 23 / 10 Current given I = 23
= 46 x 10⁻⁸ T .
Magnetic field due to current 17 A
10⁻⁷ x 2 x 17 / 10
= 34 x 10⁻⁸ T .
Magnetic field due to current 11 A
10⁻⁷ x 2 x 11 / 10
= 22 x 10⁻⁸ T .
magnetic field due to current 17 A and 11 A are in same direction so total magnetic field
= 34 x 10⁻⁸ + 22 x 10⁻⁸
= 56 x 10⁻⁸ T
magnetic field due to current 23 A in opposite direction so total magnetic field
= 46 x 10⁻⁸ - 56 x 10⁻⁸
= - 10 x 10⁻⁸ T
Magnitude = 10 x 10⁻⁸ T .
Answer: ok so u have to add the variable interia by the experiment bar to get ur total
