Answer:
E = 2.84 x 10⁵ N/ C
Explanation:
given,
initial speed of electron,u = 2 x 10⁷ m/s
final speed of electron, v = 4 x 10⁷ m/s
distance = 1.2 cm
electric field strength = ?
using equation of motion for acceleration of electron
v² = u² + 2 a s
a = 5 x 10¹⁶ m/s²
now,
Force of electric field is equal to , F = q E
and we also know that F = m a
now,
where q is the charge of electron = 1.6 x 10⁻¹⁹ C
m is mass of electron, m = 9.1 x 10⁻³¹ Kg
so,
E = 2.84 x 10⁵ N/ C
the electric field strength is equal to E = 2.84 x 10⁵ N/ C
The process of science followed my initial ideas e because it involved experiments.
<h3>What is the process of science?</h3>
The process of science or the scientific method refers to the process which scientists follow in their discovery and explanation of natural phenomena.
The scientific method is given below:
- making an observation,
- develop a hypothesis,
- making a prediction,
- conducting an experiment
- analyzing the results
- propound a law
The process of science follows my initial ideas about the process of science because I always thought science involved experiments.
In conclusion, the process of science involves making hypothesis and conducting research.

A. Controlled experiment hope this helps
The energy converted is 48 Joules
<h3>How to determine the energy</h3>
We have the formula for energy in a circuit as
Energy = Power × time
Power = I^2 R
Current, I = 2.0 A
time = 1 minute
Resistance = 12 Ohm
Substitute into the formula
Power = 2 × 2 × 12
Power = 48 Watts
Energy = 48 × 1
Energy = 48 Joules
Thus, the energy converted is 48 Joules

Answer:
Long-period comets have orbital periods longer than 200 years. ... Since it is the sublimation of these volatiles from the nucleus of the comet as it nears the Sun that gives rise to the coma and highly-visible tails, long-period comets have more material with which to put on a show.
