Answer:
a) 0 m/s
b) 4 m/s
Explanation:
The average velocity would end up being 0 because it is displacement over time and the displacement here is 0. However, speed is total distance over time which here is 400/100 so it is 4.
Answer:
The class and order levels are switched
Explanation:
Woese's classification starts with a division in three parts of all the organisms, which is their domain, so according to him there's Bacteria, Archaea, and Eukaryota. After the domain we have the kingdom, then phylum, class, order, family, genus, and species at the end.
We can take the leopard as an example:
Domain - Eukaryota
Kingdom - Animalia
Phylum - Chordata
Class - Mammalia
Order - Carnivora
Family - Felidae
Genus - Panthera
Species - Panthera pardus
Answer:
No Refraction takes places
Explanation:
When light travels from one medium to another at an angle of incidence 0 degree then no refraction takes place .
It is because according to Refraction law
sini = sinr
where are the refractive index of medium of incidence and medium of refraction .
When i = 0 , left side of the equation becomes 0 and thus r (angle of refraction) must be zero. So No refraction takes place
Answer:
carrier power is 16.1 kW
Explanation:
given data
power transmit P = 20 kW
modulation index m = 0.7
to find out
carrier power
solution
we will apply here power transmit equation that is express as
...............1
put here all value in equation 1 we get carrier power
solve it we get
carrier power = 16.1
so carrier power is 16.1 kW
