53.3 km/h is the average amount of the car trip if 80km
Answer:
kinetic energy = 414 J
Explanation:
given data
mass = 23 kg
speed = 6 m/s
height = 17 m
to find out
kinetic energy
solution
we get kinetic energy that is express as
kinetic energy = 0.5 × m × v² ..........................1
here m is mass and v is speed so
put here value we get kinetic energy
kinetic energy = 0.5 × 23 × 6²
kinetic energy = 414 J
Atoms overcome the attractive forces between them through vaporization and sublimation .in vaporization the atoms are from gas to liquid while in sublimation it is from solid to gas which skips liquid state.through this the attractive force of the atoms does not meet in the liquid state because sublimation does not undergo in liquid phase. hope this help
The displacement of the particle in the time interval 5 seconds to 8 seconds will be 1.5 meters.
Displacement is a vector quantity; meaning it has both magnitude and direction; magnitude being the distance between the interval at 5 seconds and position at 8 seconds, while the direction is from position at 5 second to position at 8 second. This is irrespective of the route followed during the time interval.
