A proton is about 1835 times more massive than an electron. If you are asking about their physical dimensions - no one knows. Scientists currently do not know how small electrons are. They are smaller than we can currently measure and may not have a size at all!
Well I figured out at his current pace, he would finish the 1100 remaining meters in 200 seconds. However, he needs to complete it in 180 seconds. I'm not sure how to find out how long he has to accelerate at 0.20 m/s/s to complete it in 180 seconds.
Answer:
A) electric field strength between the plates;E = 2 x 10^(6) N/C
B) exit velocity;v = 8.39 x 10^(7) m/s
Explanation:
We are given;
Potential difference; V = 20 kV = 20000 V
Distance between the 2 parallel plates; d = 1cm = 0.01 m
A) The electric field strength will be gotten from;
E = V/d
E = 20000/0.01
E = 2000000
E = 2 x 10^(6) N/C
B) For exit speed, we'll use the formula for Kinetic energy; KE = (1/2)mv²
KE is also expressed as; V•q_e
Thus,
(1/2)mv² = V•q_e
Where;
V is potential difference = 20000 V
Q_e is charge of electron which has a constant value of; (1.6 x 10^(-19))C
m is mass of electron with a constant value of (9.1 x 10^(-31)) kg
v is the velocity
Thus, making v the subject, we have;
v = √((2V•q_e)/m)
v = √((2 x 20000•(1.6 x 10^(-19)))/(9.1 x 10^(-31)))
v = 83862786 m/s or
v = 8.39 x 10^(7) m/s
Based on Patient B's history "nerve damage" diagnosis is most logical.
<u>Answer:</u> Option C
<u>Explanation:</u>
Signs rely on which nerve is harmed, and whether one nerve, several nerves or the entire body is affected by the damage. In the arms and legs tingling or burning can be an early indicator of nerve damage. Disruption to the nerves can make regulation of the muscles more difficult. It can also cause frailty.
A test of nerve conduction velocity (NCV) also termed a study of nerve conduction initiatives how quickly an electrical impulse goes through the nerve. NCV can recognize any real harm to the nerves. The nerve is stimulated during the test, generally with patches of electrodes fixed to one's skin.
