Answer:
Calculate the wavelength associated with an electron with energy 2000 eV.
Sol: E = 2000 eV = 2000 × 1.6 × 10–19 J
Answer:

Explanation:
When two cars collide then the momentum of two cars will remains conserved
- Mass of two cars = 100 kg
-
Speed of car B = - 10 m/s
-
After collision the speed of car B = +8 m/s
By momentum conservation equation


Answer:
1000m/s²
Explanation:
Given parameters:
Initial velocity = 6000m/s
Final velocity = 11000m/s
Time = 50s
Unknown:
Acceleration of the plane = ?
Solution:
Acceleration is the rate of change of velocity with time:
Acceleration = (final velocity - starting velocity) ÷ time
Therefore;
Acceleration =
= 1000m/s²
