Answer:
206 pm
Explanation:
We are given that
Potential difference,
Distance,d=
We have to determine the de Brogile wavelength of the electron.
A=11 and B=5
Charge on electron,q =
Mass of electron=m=
Speed of electron,
Using the formula
v=
de Brogile wavelength, 
Where 
1 pm=
The masses of both objects and the distance between their centers.
Answer: it's c or 4.0 m/s
Explanation:
The acceleration of the falling object with a mass of 2.55 kg that encounters 4.0 N of air resistance is 1.57m/s².
<h3>How to calculate acceleration?</h3>
Acceleration is change of velocity with respect to time (can include deceleration or changing direction).
The acceleration of a body can be calculated by using the following expression;
a = F/m
Where;
- a = acceleration (m/s²)
- F = force (N)
- m = mass (kg)
According to this question, a mass of 2.55 kg encounters 4.0 N of air resistance. The acceleration of the object can be calculated as follows:
a = 4N ÷ 2.55kg
a = 1.57m/s²
Therefore, 1.57m/s² is the acceleration of the object.
