The magnetic field strength in a coil is directly proportional to the number of turns, or loops, in the coil.
Therefore, when there are four loops instead of one, the magnetic field strength has increased four times, making it harder to push the magnet in.
23) 560 cm
25) 3100 mg
27) 8.89 cm
29) 525 g
31) I can't see the measurement it needs to be converted to
Answer:
foam but thats what i heard from other people
Explanation:
Actually Welcome to the Concept of the Rays of light.
Since we know that, The light ray on a shiny surface makes a angle with the normal, hence The Angle of incidence is equal to angle of reflection made with Normal Axis in the middle.
Thus Option c.) is correct.
C.) is the Answer.
This is a beautiful problem to test whether a student actually understands
Newton's 2nd law of motion . . . Force = (mass) x (acceleration).
That simple law is all you need to solve this problem, but you need to
use it a few times.
m₁ alone:
Force = (mass) x (acceleration)
36 N = ( m₁ ) x (6 m/s²)
m₁ = (36 N) / (6 m/s²)
m₁ = 6 kilograms .
m₁ and m₂ glued together:
Force = (mass) x (acceleration)
36 N = (6 kg + m₂) x (2 m/s²)
6 kg + m₂ = (36 N) / (2 m/s²) = 18 kilograms
m₂ = 12 kilograms .
m₂ alone:
Force = (mass) x (acceleration)
36 N = (12 kg) x (acceleration)
Acceleration = (36 N) / (12 kg)
Acceleration = 3 m/s²
