Answer:
the magnitude and direction of the magnetic field in the region through which the current passes is 0.008 T and +z direction.
Explanation:
given information:
current, I = 20 A
magnetic force per unit length, F/L = 0.16 N/m
the conductor in the negative y-direction
θ = 90° (perpendicular)
as we know the formula to calculate magnetic force is
F = B I L sin θ
B = F/(I L sin θ)
= (F/L) (1/I sin θ)
= 0.16 (1/15 sin 90)
= 0.008 T
since F is in the negative y direction, based of the right hand rule the magnetic field is in positive z direction
Answer:
Explanation:
Given:
current, I = 20 A
Magnetic force per unit length, F/L
= 0.16 N/m
Conductor in the negative y-direction, therefore θ = 90° (perpendicular)
For a magnetic field,
F = B I L sin θ
B = F/(I L sin θ)
= 0.16 × (1/15 sin 90)
= 0.008 T
The field is in the +ve z - direction.
green light in the visible portion of the electromagnetic radiation sepectrum has a wave length around 550nm.Express this wavelength in meters using exponential notation
The wavelength of green light in meters using exponential notation is 5.5 × 10-7 m.
Explanation:The green light in the visible portion of the electromagnetic radiation spectrum has a wavelength of around 550 nm (nanometers).
To express this wavelength in meters using exponential notation, we can convert nanometers to meters by dividing by 109. So, the wavelength of green light is 5.5 × 10-7 m (meters).
