Answer:
the chemical reaction will be fire and smoke
Answer:
Gravitational potential energy is due to the position of an object above Earth's surface. The object has the potential to fall due to gravity.
Explanation:
Gravitational potential energy depends on an object's weight and its height above the ground (GPE = weight x height). hope this helps you :)
Answer:100joules
Explanation:
Mass(m)=5kg
Acceleration due to gravity(g)=10m/s^2
Height(h)=2 meters
Work=m x g x h
Work=5 x 10 x 2
Work=100joules
Answer:6km/sec
Explanation: Acceleration = Change in velocity / Time
Change in velocity = 60km/h minus 30km/hr
Time = 5seconds
1) The electric field between the two plates is
. The potential difference between the plates is given by
where d is the separation between the plates. By using
we find
2) The work done by the electric field to move the electron by that distance is equal to the variation of electric potential energy of the electron:
where e is the electron charge. By substituting numbers, we find
