Answer:
light reflects off the objects and enter our eyes
When the velocity is uniform, the velocity does not change. since acceleration is the rate of change in velocity, the acceleration will be zero when velocity is uniform
Answer:
The fractional kinetic energy will be lost if the collision is inelastic. In inelastic collision, the kinetic energy is converted into other forms of energy.
The lost energy became heat and sound energy.
Explanation:
During inelastic collision, the kinetic energy of a moving object does not conserve. It changes into another form of energy such as sound energy and heat energy etc.
For example, when a moving car hit another car or wall etc, the kinetic energy is converted into sound and heat energy. This type of collision is inelastic collision.
Should be -9.8m/s^2!!! The force of gravity is the only thing pushing it down!!
Hope I helped you out!!
The chemical equation in this case is given by:
Zn (2+) + 2e (-) ------> Zn
It can be noted that 1 mole of Zn is produced by 2 Faraday of electricity.
For 29.1 moles,
Total charge required = 2*29.1 = 58.2 F
But, 1F = 96500 C
Then,
Amount of charge required = 96500*58.2 = 5,616,300 C
