U = 0, initial velocity
t = 1.85 s, the time of flght
Assume g = 9.8 m/s² and no air resistance
If the velocity of impact is v, then
v = u + gt
v = (9.8 m/s²)*(1.85 s) = 18.13 m/s
Answer: 18.13 m/s
Answer: C) a natural resource that humans use to generate energy
So basically its anything found on earth to make energy. This includes nonrenewable sources such as fossil fuels (coal or natural gas), and renewable sources such as wind, hydro or solar.
1. Domain.
<span>Info: Domain is the largest taxa, and there are only three domains: Archaea, Bacteria, and Eukarya. </span>
<span>As a rule of thumb the less number of members a taxa has, the broader spectrum of organisms it carries. </span>
<span>2. Specific epithet </span>
<span>Info: The Genus is Loxodonta (italicized), the family Elephantidae, the Domain's Eukarya. </span>

Answer:
The correct option is D
Junction diodes are preferred over point-contact diodes for most purposes.
Explanation:
Point contact diode:
This type of diode is constructed by touching a metallic wire with an N-type semiconductor to form a small area of contact, hence the name point contact diode. The switching speed of these diodes is better than a conventional diodes.
These diodes are not usually preferred due to their low current ratings and poor reliability.
P-N junction diode:
This type of diode is constructed by joining two regions of opposite conductivity N-type and P-type material, a PN-junction is formed which allows the current to flow in one direction only. The conversion of AC current to DC is done by this process called rectification.
