Answer:
Explanation:
Magnetic field due to moving charge =

q is charge moving with velocity v and r is distance from point at which field is calculated .
For alpha particle

= 0.1316 x 10⁻³ T
For electron

= .0658 x 10⁻³ T .
Both these magnetic field will be same in direction because direction of equivalent current is same for both the particles .
Hence
Total magnetic field
= B₁ + B₂ = .1974 x 10⁻³
= 1.974 x 10⁻⁴ T .

jk you didnt share the video lol
Coal plants use a boiler to produce steam.
Answer:
Explanation:
a)
A = 3m , B = 4m .
(A-B)² = A² + B² - 2ABcosθ where θ is angle between A and B.
4 = 9 + 16 - 2. 3.4 cosθ
cosθ = .875
θ = 29° .
b ) Unit vector in the direction of A X B will be k vector because A and B are in X-Y plane and A X B lies perpendicular to both A and B .
As the climber climbs the mountain, he needs to over his or her own weight component along the slope of the mountains.
By Newton's second law: Net force = Mass x acceleration
Hence, greater the mass, greater will be the force required to move up the mountain. Hence, the climber will need to apply higher force to climb up as he or she has packed too much, which resulted in the increase in the mass. Hence, there is a increase in the force which will pull him or her downward.
