Answer:
false
A hypothesis states a presumed relationship between two variables in a way that can be tested with empirical data. ... The cause is called the independent variable; and the effect is called the dependent variable.
89.67J
Explanation:
Given parameters:
Mass of rock = 6.1kg
Height of fall = 1.5m
Unknown:
Potential energy = ?
Solution:
The potential energy is the energy at rest or due to the position of a body.
Potential energy is mathematically expressed as;
Potential energy = mgh
m is the mass of the rock
g is the acceleration due to gravity of the rock
h is the height of the rock
Potential energy = 6.1 x 9.8 x 1.5 = 89.67J

<h2>Answer:</h2>
The correct answer is option D. Which is "Over time, the lawn has naturally become disorderly".
<h3>Explanation:</h3>
- Entropy, the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.
- It is also a measure of the molecular disorder, or randomness, of a system.
- According to above definitions of entropy option D is correct.
- <u>So entropy of system is randomness/disorder that is increasing with time in case of lawn.</u>
Answer:
Gravity Increases - Mass increases, distance decreases
Gravity Decreaes - Mass decreases, distance increases
