Ancient species living in earth with all its close relatives dead are called living fossils.
<h3><u>Explanation:</u></h3>
Living fossils are interesting as well important creations of nature. Let's take an example of a plant <em>Ginkgo biloba</em>. Its a plant of gymnosperm family along with pine and fir, but belongs to the order Ginkgoales. In this order, Gingko biloba is the only plant that's alive till now, all the other species are dead.
Living fossils give us important informations about the adaptation that used to prevail in earth that lead to survival of species in contemporary times. It also establishes relationships between the two or more phyla of organisms in a taxonomic way.
Animal living fossils are lungfish, horse shoe crab, coelacanth fish, Tuatara, lobe finned fishes etc.
The equation to be used is for the rectilinear motion at constant acceleration:
x = v₀t + 0.5at²
a = (v-v₀)/t
where
x is distance
v and v₀ is the final and initial velocity
t is time
a is acceleration
Because the acceleration is decelerating, that would be reported as -7.5 m/s². Substituting,
-7.5 = (0 - v₀)/t
v₀ = 7.5 t --> eqn 1
x = v₀t + 0.5at²
60 = (7.5t)(t) + 0.5(-7.5)(t²)
Solving for t,
t = 4s
Thus,
v₀ = 7.5 m/s² * 4s
v₀ = 30 m/s
Answer:
E = 440816.32 N/C
Explanation:
Given data:
Three point charge of charge equal to +3.0 micro coulomb
fourth point charge = - 3.0 micro coulomb
side of square = 0.50 m
N.m^2/c^2
Due to having equal charge on center of square, 2 charge produce equal electric field at center and other two also produce electric field at center of same value
So we have
[
[
]
plugging all value
E = 440816.32 N/C
Answer:
the answer is true Induction charging is a method used to charge an object without actually touching the object to any other charged object.
