Answer:

23.64 m

Explanation:

Potential energy is given by

PE=mgh

Where m us the mass of snowball, g is acceleration due to gravity, h is height.

Also, the weight of an object is given by W=mg hence replacing mg in the above equation with W we obtain

PE=Wh

Making h the subject of the formula then

$h=\frac {PE}{W}$

Substituting 520 J for PE and 22 N for W then

$h=\frac {520J}{22}=23.636363636363m\\h\approx$

Ions can have a positive or negative charge. Please select the best answer from the choices provided T F

mixas84 [53]

From among the choices provided, the more appropriate
answer is ' T ', the initial letter often used to represent
words that include 'true', 'truth', 'trust', etc., (as well as
'tree', 'train', 'transmit', 'Transylvania', 'trachea', 'travesty',
and 'trick', which are irrelevant to the present discussion).

This response is the most fitting and appropriate, because
the statement that precedes the list of allowable choices is
exemplary in its accuracy and veracity. An ion can, in fact,
have a positive or negative charge, although the same ion
cannot have both.
