Answer:
Explanation:
The speed of the bullet will only be the same if the mass of the bullet is equal to the mass of the gun. This because only their momentum ( product of mass and velocity) is conserved; the momentum before the gun and pullet was fired is equal to the momentum of the recoil of the gun and the momentum of the released bullet. The smallest mass receives the highest speed (the bullet) while the larger mass ( the gun) receives the lowest speed ( speed of recoil).
Answer:
Explanation:
We shall use Ampere's circuital law to find magnetic field at required point.
The point is outside the circumference of two given wires so whole current will be accounted for .
Ampere's circuital law
B = ∫ Bdl = μ₀ I
line integral will be over circular path of radius r = 41 cm .
Total current I = 5A -3A = 2A .
∫ Bdl = μ₀ I
2π r B = μ₀ I
2π x .41 B = 4π x 10⁻⁷ x 2
B = 2 x 10⁻⁷ x 2 / .41
= 9.75 x 10⁻⁷ T . It will be along - ve Y - direction.
<span>The one that does not separate white light into the colors of the visible spectrum is A, rods in the retina of the human eye. The rod is a cells that can work in less extreme light than the other sort of visual photoreceptor, cone cells. Poles are generally discovered accumulated at the external edges of the retina and are utilized as a part of the fringe vision.</span>
