Answer: kinetic energy
Explanation:
Kinetic energy is the form of energy related to the motion of an object. The kinetic energy of an object is given by:
where m is the mass of the object and v its speed. Therefore, any object in motion has kinetic energy: in this case, the bowling ball is in motion before the collision, so during the collision it transfers its kinetic energy to the pins.
The height of the plane delivering a food package to people stranded on an island is 722.2 m.
<h3>
Time of motion of the food package</h3>
The time taken for the food package to hit the ground level is calculated as follows;
X = vt
where;
- X is horizontal distance traveled by the food package
- v is horizontal distance
- t is time of motion
t = X/v
t = 789/65
t = 12.14 seconds
<h3>Height of the plane</h3>
h = ¹/₂gt²
where;
- h is height of fall of the food package which is height of the plane
- t is time of motion of food package
- g is acceleration due to gravity
h = (0.5)(9.8)(12.14²)
h = 722.2 m
Thus, the height of the plane delivering a food package to people stranded on an island is 722.2 m.

Answer:
cross-sectional
Explanation:
The full definition of this is ''a research design in which several different age-groups of participants are studied at one particular point in time.''
Answer:
18
Explanation:
we need the to know the extra weight Eric has over Tom. To do that we need to subtract Tom's weight from Eric's, but now we do not know what Eric's weight is or Tom's weight. the only clue we have is that Eric is 4 inches taller than Tom
1. if Eric is 4 inches taller that Tom, then
let
Tom's height be
and
Eric's height will be 4 inches more
let's plug these two information into the formula given in the question
for the difference in their weight;
Eric's weight will be;
w =
Tom's weight will be
w =
taking the difference between the two expressions above
w =
opening the bracket
w =
w = 18 pounds
so Eric's weight is 18 pounds more than Tom's
