D. The environment
Is the right answer
Answer: F
Out of the page.
Explanation:
For an electron with a charge of -e, the magnitude of the force on it is F = BeV
Where
F = force on the electron
e = charge ( electrons )
V = velocity
B = magnetic field
F is the force acting on all the electrons in a wire which gives rise to the F = BIL
Where
I = current
L = length of the wire
The force F is always at the right angle to the particle's velocity and its direction can be found using the left hand rule.
When the electron is moving in the plane of the page in the direction indicated by the arrow, the force on the electron is directed out of the page.
Answer:
1.8x10⁻³m
Explanation:
From the question above, the following information was used to solve the problem.
wavelength λ = 4.5x10⁻⁷m
Length L = 2.0 meters
distance d = 5 x 10₋⁴m
ΔY = λL/d
= 4.5x10⁻⁷m (2) / 5 x 10₋⁴m
= 0.00000045 / 0.0005
= 0.0000009/0.0005
= 0.0018
= 1.8x10⁻³m
from the solution above The separation between two adjacent bright fringes is most nearly 1.8x10⁻³m

Producers get energy from the sun to make food from matter.
Answer:
The energy consumption by toaster oven is 432 kJ and that of fluorescent light (CFL) bulb is 435 kJ.
Explanation:
Power of toaster oven, P = 1.2 kW
Time, t = 6 minutes = 360 s
The energy used by toaster oven is given by :
Power of fluorescent light (CFL) bulb, P' = 11 W
Time, t' = 11 h = 39600 s
Energy used by fluorescent light (CFL) bulb is given by :
So, the energy consumption by toaster oven is 432 kJ and that of fluorescent light (CFL) bulb is 435 kJ.
