One charge is enough in order to have an electric field.
In fact, every charge generates an electric field: for example, the electric field generated by a single point positive charge is radial, as shown in the attached figure. More complicate electric field configurations can be obtained adding charges or using more complicate charge distributions, but one charge is enough to have an electric field.
Answer:
None of the animals are from the same species
Explanation:
The exact question is as follows :
Given -
Felis catus
Sylvilagus audubonii
Parus inornatus
Euarctos americanus
Check out the list of scientific names. These names all represent animals. These are all animals but they cannot reproduce to produce fertile offspring with each other.
To find - What conclusion can be drawn from the past statement?
Solution -
The conclusion we can made from past statement is that - None of the animals are from the same species
Reason -
When two members of the same species reproduce, they produce fertile offspring.
According to the scientific names of the animals, there are different genus and species names.
Answer:
R = 60 Ω
Explanation:
given,
Potential of the certain device, V = 120 V
current rating of the circuit, I = 20 A
resistance of the device, R = ?
Using Ohm's Law
V = I R
R = 60 Ω
hence, the resistance of the device is equal to 60 Ω
Except for mass, length, time, and electric charge, EVERY quantity is
a combination of units ... of THOSE units in fact. Hadn't you noticed ?
Answer:
12 kJ
Explanation:
Given:
v₀ = 0 km/h
a = 5 km/h²
t = 30 min = 0.5 h
Find: v
v = at + v₀
v = (5 km/h²) (0.5 h) + 0 km/h
v = 2.5 km/h
v = 2.5 km/h × (1000 m/km) × (1 h / 3600 s)
v = 0.694 m/s
KE = ½ mv²
KE = ½ (50,000 kg) (0.694 m/s)²
KE = 12,000 J
KE = 12 kJ
