Answer:
V = 10581.59 V
Explanation:
To solve this problem, we have to take into the relation between the kinetic energy of an electron and the energy generated by the potential difference of an electric field. This relation is given by
where m is the mass of the electron, v is the velocity of the electron, e is the electric charge and V is the potential difference that accelerated the electron.
By taking V from the last expression we have:
where we have taken that
me = 9.1*10^(-31) Kg
e = -1.6*10^(-19) C
v = 6.1*10^(7)
I hope this is useful for you

<u>Answer:</u>
Prior to exercise, a proper warm-up of 10-15 minutes is extremely important to avoid injuries.
- Don't go too hard in the beginning and boost your activity level slowly. A good indication of a proper warm-up is that you feel sweat on your body parts.
- Don't overstretch right in the beginning as it can cause sore in your muscles and joints or stress fractures.
- Take a break if you feel sick or fatigues and use other drinks along with water to replace electrolytes and body fluids.
Answer:
C
Explanation:
Definition of drug: a medicine or other substance which has a physiological effect when ingested or otherwise introduced into the body
with 50 km/h = 15m skid
so, 150 km/h = 45m skid
multiply sides by 3, make them proportional to each other!!!
