Answer:
This oxygen reacts with the carbon of the positive electrodes, forming carbon dioxide, so they gradually burn away. As a result, the positive electrodes have to be replaced frequently. This adds to the cost of the process.
Answer:
Proton’s speed, a short time later when it reaches a point of lower potential is 1.4 x 10⁵ m/s
Explanation:
Given;
initial speed of proton, u = 2.5 x 10⁵ m/s
initial potential, V = 1500 V
mass of proton = 1.67 x 10⁻²⁷ kg
Work done, W = eV= ΔK.E = ¹/₂mu²
eV = ¹/₂mu² (J)
where;
e is the charge of the proton in coulombs
V is the electric potential in volts
m is the mass of the proton in kg
u is the speed of the proton in m/s
Therefore, proton’s speed a short time later when it reaches a point of lower potential is 1.4 x 10⁵ m/s
Answer:
a) 
b) 
Explanation:
From the question we are told that:
Width of diffraction grating 
Width of silt 
Distance
a)
Generally the grafting element is the distance b/w the silts
Therefore the grafting element is
b)
Generally the equation for diffraction state is mathematically given by
Since
Therefore
Therefore orders observed with 
is
a. The risk of injury must be predictable.
b. A "breach of duty" is when a professional fails to uphold a level of care.
c. There must be a standard of care in place, and the practitioner must assume responsibility for the patient.
d. There must be a clear link between the treatment received and the harm.
<h3>What is malpractice?</h3>
Malpractice, commonly referred to as professional negligence, is defined as "an incident of carelessness or incompetence on the part of a professional" under tort law.
The following professionals might be the target of malpractice claims:
Medical professionals: If a doctor or other healthcare practitioner does not exercise the level of care and competence that a similarly situated professional in the same medical field would deliver under the circumstances, a medical malpractice claim may be made against them.
Lawyers: Failure to provide services with the amount of competence, care, and diligence that a reasonable lawyer would use in the same situation may be grounds for a legal malpractice claim.
