Explanation:
an echo mimics exactly what is said, this is like a mirror because when you look in a mirror every action you make is copied by your reflection
Answer: B. The gravitational field strength of Planet X is Wx/m.
Explanation:
Weight is a force, and as we know by the second Newton's law:
F = m*a
Force equals mass times acceleration.
Then if the weight is:
Wx, and the mass is m, we have the equation:
Wx = m*a
Where in this case, a is the gravitational field strength.
Then, isolating a in that equation we get:
Wx/m = a
Then the correct option is:
B. The gravitational field strength of Planet X is Wx/m.

The historical method includes what steps?
Answer:
sp3d
Explanation:
=1
sp=2
sp^2=3
sp^3=4
sp^3d=5
As we add, we can make one more bond...since this says MORE than four bond, the answer must be sp^3d.
