Answer:
5 Joules, 7.5 Joules and 10 Joules respectively
Explanation:
Potential energy due to gravity is given by mass*gravity*height or weight*height(As weight= mass*gravity)
The potential energy at the height of 1 meters = 5*1 = 5 Joules
The potential energy at the height of 1.5 meters = 5*1.5 = 7.5 Joules
The potential energy at the height of 2 meters = 5*2 = 10 Joules
Huh? pls elaborate i don’t understand
Answer:
kinectic energy-in physics kinetic energy of an object is the energy that it possesses due to its motion
- it is defined as the work needed to accelerate a body of a given mass from rest to its started velocity.having
- gained this energy during its acceleration
- The body maintains this kinetic energy unless its speed changes.
potential energy-in physics potential energy is the energy held by an object because of its position relative to other objects,its electric charge,or other factors
- in the case of a bow and arrow ,when archer does work on the bow drawing the string back
- some if the chemical energy of the archer's body is transformed into elastic potential energy in the bent limb of bow

Explanation:
14 g is the solubility per 100 g water, since it is difficult to read the graph.
<span>Then, in 130 g H20 the solubility would be 14 g KNO3/100 g H2O x 130 g H2O = 18 g KNO3 </span>
<span>The question asks how much crystallizes. </span>
<span>Initial 34.0 g minus 18.0 g still dissolved = 16.0 g crystallizes.</span>
