Your subject squeezes the hand dynamometer as hard as she can with each hand and records a value of 12 for the left hand and 10 for the right hand. What are the four intensities would you use in experiment 1. Select one:

a. 2.5, 5, 7.5, 10 psi
b. 3, 5, 8, 10 psi
c. 3, 6, 9, 12 psi
d. 0, 3, 6, 10 psi

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

its c i just checked it
