The area between the thorajand pelvis in humans constitutes the part of the body
known as the SPINE
I agree with Maria and disagree with Mike.
The earth has gravity and that pulls objects towards the center of the planet
We use mass, volume and density relation as,
Here, m is mass , V is volume and is density.
Also,
Here, and t is thickness.
Given , and.
Therefore, from above formula
.
Thus, diameter of the plate,
Answer: So, our current when our switch is open is going to be equal to the voltage across the resistors, and that's going to be our 12 volts, 12 volts, divided by the equivalent resistance of these resistors. When the switch is open, essentially, we just have R1 and R2 in series, and so this is just gonna be R1+R2.
Hope this helps......... Stay safe and have a Merry Christmas!!!!!! :D
We can solve the problem by using the law of conservation of energy.
Initially, the rock has only gravitational potential energy, which is given by
where mg is the weigth of the rock (2200 N), while h is the height at which the rock has been released (h=15 m). If we calculate it, we get
Just before hitting the ground, the rock height is zero, so its potential energy is now zero. So the total mechanical energy of the rock now is just kinetic energy:
however, the mechanical energy of the rock must be conserved, so
and so we have that the kinetic energy of the rock just before hitting the ground is equal to its initial potential energy:
