Which estimate is realistic? A) Volume of air in an inflated balloon is around 22.4dm³.
B) Weight of an apple is around 3.0N.
C) Area of a piece of tissue paper is around 17cm².
D) Potential energy of an adult living in a 2 story house is around 2500J.
E) Kinetic energy of a baby crawling on the ground is around 9.0J.

Provide a short explanation as to why you believe your answer is the most realistic.

Astone is dropped with no initial velocity from the top of a cliff and hits the ground a time of 3.9 s later. what is the height of the cliff, in units of meters? you may assume that air resistance is negligible. give the answer as a positive number question 15 a figure skater is rotating at a rate of 200 revolutions per minute. what is the angular speed, in units of rad/s? 200 o 20.9 12000 o 3.33

How does the kinetic energy of a charge change as the charge moves under the effect of an electric field from higher potential to lower potential? a.the kinetic energy increases.b.the kinetic energy decreases.c.the kinetic energy remains the same.d.the kinetic energy is always zero.

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.
