Answer:
Explanation:
The two major defects of simple electric cells causes current supplied to be for short time. These defects are: polarization and local action.
a. Polarization: This is a defect caused by an accumulation of hydrogen bubbles at the positive electrode of the cell. It can be prevented by the use of vent, using a hydrogen absorbing material or the use of a depolarizer.
b. Local Action: This is the gradual wearing away of the electrode due to impurities in the zinc plate. It can be controlled by the amalgamation of the zinc plate before it is used.
Answer:
It’s 18.0 m/s
Explanation:
Use acceleration formula then plug in 9.8 and 1.84s
The total energy equation would be Kinetic energy+Potential energy
I believe it’s density and temperature
A leaf is organic matter because organic matter refers to anything from something living. because a leaf is living or was at one point it is organic matter
