Answer:
The kinetic energy will remain constant
Explanation:
Charged particles in a magnetic field feel a force perpendicular to their velocity, since the force is F = qvB, and a charged particle feels a force of constant magnitude always directed perpendicular to its motion which causes circular motion in the magnetic field but the speed and kinetic energy of the particle will remain constant.
Therefore, if only the magnetic field acts on the particle, its kinetic energy will remain constant.
Answer:
Organic systems used 45% less energy overall than conventional systems. Production efficiency was 28% higher in the organic systems, with the conventional no-till system being the least efficient in terms of energy usage.

Answer:
20.7 volts
Explanation:
m = mass of electron = 9.1 x 10⁻³¹ kg
λ = wavelength of electron = 0.27 x 10⁻⁹ m
v = speed of electron
Using de-broglie's hypothesis
λ m v = h
(0.27 x 10⁻⁹) (9.1 x 10⁻³¹) v = 6.63 x 10⁻³⁴
v = 2.7 x 10⁶ m/s
ΔV = Potential difference through which electron is accelerated
q = charge on electron = 1.6 x 10⁻¹⁹ C
Using conservation of energy
(0.5) m v² = q ΔV
(0.5) (9.1 x 10⁻³¹) (2.7 x 10⁶)² = (1.6 x 10⁻¹⁹) ΔV
ΔV = 20.7 volts
A) 20 m
<h3>What is called magnitude of displacement?</h3>
The magnitude of displacement is defined as the shortest distance between the initial and final position of the object.
For a particle in motion, the magnitude is either less than or equal to the distance travelled.
Also,
Velocity is simply defined as the rate of change of displacement with time.
Mathematically, it can be expressed as:
Velocity = displacement / time
According to the question,
The following data were obtained:
Time = 5 s
Velocity = 4 m/s
Displacement =?
Velocity = displacement / time
4 = d / 5
D = 4 × 5
D= 20 m
Hence,
20 m is the magnitude of the displacement of the object after it travelled for five seconds.
