Electric circuit. Hoped that helped
Answer:
a) a = 5.03x10¹³ m/s²
b) 
Explanation:
a) The acceleration of the positron can be found as follows:
(1)
Also,
(2)
By entering equation (1) into (2), we have:
<u>Where:</u>
F: is the electric force
m: is the particle's mass = 9.1x10⁻³¹ kg
q: is the charge of the positron = 1.6x10⁻¹⁹ C
E: is the electric field = 286 N/C
b) The positron's speed can be calculated using the following equation:
<u>Where</u>:
: is the final speed =?
: is the initial speed =0
t: is the time = 8.70x10⁻⁹ s
I hope it helps you!
yes this is correct good job
Answer:
The answer is below
Explanation:
Because of the resistance of transmission lines, high current along the line leads to large voltage drop. This voltage drop causes low efficiency because the voltage at the receiving end is far less than that at the sending end.
Therefore there is need to transmit at a higher voltage (smaller current) than that required by distribution because of efficiency.
Hence, For safety and efficiency, the voltage must be large in the transmission lines and small in the distribution lines.
The impact force makes sense because the impulse experienced by the body cause a great change in momentum of the body.
<h3 /><h3>What is impulse?</h3>
This is the force that acts on a body over a given period of time. The impulse experienced by a body is determined as the product of force and time of action.
J = Ft
The change in momentum of a body is equal to the impulse experienced by the body.
ΔP = Ft
Thus, the impact force makes sense because the impulse experienced by the body cause a great change in momentum of the body.
