The work done by the electric field is given by:
where q is the charge, and
is the potential difference between point A and B. But the potential difference is equal to
where E is the intensity of the electric field, while d is the distance between the two points A and B.
Therefore, the work done by the field is
Answer: The acceleration for the shuttle is 13 800m/s^2.
Explanation:
The answer is required is si unit which is m/s^2.
The first step is to convert to velocity to m/s, 1km=1000m therefore we have to multiply by 1000
5km/s=5000m/s
11.9km/s=11900m/s.
The formula for the acceleration is a=dv/t
a=11900-5000/0.5
a=13 800m/s
I think its C or D.
Einstein's Nobel winning photoelectric equation.
The higher the work function, the more energy needed to photoeject an electron from the surfface
Try D
I think c I’m not sure tho
Answer
correct answer is 3.10
Explanation:
in this question we have to multiply two numbers 1.003 and 3.09.
1.003 has 4 significant digits and 3.09 has 3 significant digits so answer must have 3 significant digits.
Hope it will help you
