The functions that would be performed both by the placenta and the hatchery so that the embryos will survive is to maintain the temperature of the embryos. The temperature should also be at the temperature where the embryos would thrive and develop.
The centre of mass of the objects is (0,1)m .
What do you mean by Centre of mass?
The centre of mass is a position defined relative to an object or system of objects .
We have given
m1=2kg , y1= 3
m2= 3kg ,y2=2.5m
m3=2.5kg ,y3= 0m
m4=4kg , y4= -0.5m
Ycm=mixi/mi
→2×3+3×2.5+2.5×0+4×0.5/4.5
→1m
Centre of mass of these object is at (0,1)m .

Answer:
the potential at point B is 5 V, Option d) is the correct answer
Explanation:
Given that;
from the image;
R = 3 + 4 + 5 = 12 Ω
so I = 12/12 = 1 A
Q = 0 + 12 = 12 V
now
VA - VQ = - I × 3 = -3 V
VA = VQ - 3 = 12 - 3 = 9 V
VB - VA = - I × 4Ω = - 4 V
⇒VB = VA - 4 = 9 V - 4 V = 5 V
Therefore the potential at point B is 5 V
Option d) is the correct answer
Invertebrates vary tremendously in their body composition. It's common for invertebrate species to have four distinct stages to their life cycle: egg, larva, pupa, and adult, although this life cycle can vary. For example, octopus and squid hatch and grow into adults without a larva or pupa stage.
