Answer: velocity
Explanation: Hope this helps :)
In order to develop this problem it is necessary to use the concepts related to the conservation of both potential cinematic as gravitational energy,


Where,
M = Mass of Earth
m = Mass of Object
v = Velocity
r = Radius
G = Gravitational universal constant
Our values are given as,



Replacing we have,




Therefore the speed of the object when striking the surface of earth is 4456 m/s
Depending on whether they where conjoined initially, or where born separately really changes the answer of this question. Although studies show that twins generally have a kinetic link, more practical research says that twins are 25% more likely to both be left handed, which is a recessive gene, they are also more likely to die in child birth, twins are more likely to understand and be biligual, along with many other advantages twins may have.
Answer:
35.7 mA
Explanation:
The magnetic field inside a solenoid is given by:
(1)
where
is the vacuum permeability
I is the current
n is the number of turns per unit length
Since we have
N = 870 turns
L = 0.390 (length of the solenoid)
we can calculate n

And now we can re-arrange eq.(1) to find the current, I:
