Step-by-step explanation:
Answer:
1. The strength of magnetic field at A is 64 unit, then the magnetic field strength at B. is 256 units.
64 × 64 = 256 units.
2. If the strength of magnetic field B is 6 units then the strength magnetic field at A is 24 units.
which is 256 : 4 = 16 units.
Magnetic field is one of the two ways where the intensity of magnetic field is being expressed.
Answer:
y = 192
Step-by-step explanation:
Given y varies directly as z and inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 16 and z = 2 when x = 42
k = = = 336
y = ← equation of variation
When x = 14 and z = 8, then
y = = 192
